Chairman’s Letter

Dear Shareholder,

Stock prices scampered higher in the face of uncertainty about the strength of the global recovery. For the six months ended June 30, Vanguard 500 Index Fund followed the market’s gains and retreats, performing in line with the 6.02% return of the S&P 500 Index. The fund topped the average return of its peer group, large-capitalization core funds.

All but one of the fund’s ten sectors posted positive returns for the period. The double-digit returns delivered by health care and energy stocks were notable bright spots. Weakness in the information technology sector, the single largest component of the S&P 500 Index, and a decline in the financial sector held back the six-month returns.

For most stock markets, a ragged six-month gain
Like the U.S. market, global stock markets climbed unsteadily as investor attitudes swung from optimism about the strength of corporate earnings to fears that the slow, grinding recovery was losing momentum. Stock prices rallied through the first four months of 2011, pulled back as economic news turned gloomier, then bounced up again at the end of the period.

The broad U.S. stock market returned about 6% for the six months. International stock markets finished a few steps behind, restrained by sovereign-debt dramas in Europe and the economic aftershocks of the Japanese natural and nuclear disaster. Gains were modest in emerging markets, too, as big economies such as China and Brazil grappled with inflationary pressures.

Low yields, solid returns in the U.S. bond market
Bonds delivered solid six-month returns even as interest rates hovered near generational lows. Bond prices rallied in the spring as economic anxiety prompted a search for safer havens in fixed income. The broad taxable bond market returned almost 3%. The municipal market performed even better. Municipal securities were hammered early in the year as unsettling (and in our opinion, overstated) headlines raised doubts about their safety. Toward the end, investors’ worries began to recede and prices rose.

The yields on money market instruments remained nearly invisible, consistent with the Federal Reserve Board’s target for short-term interest rates, which since December 2008 has been anchored between 0% and 0.25%.

Strength in health care and energy carried the fund’s stocks higher
The 500 Index Fund produced a solid half-year return despite the anxiety and pronounced volatility triggered by unsettling events on the global stage. The market’s— and corporate America’s—resilience was

notable. Nine of the S&P 500 Index’s ten sectors produced gains, and corporate earnings continued to rebound powerfully from their recessionary depths.

Health care stocks contributed the most to the fund’s performance, returning nearly 14% for the period and accounting for almost 1.5 percentage points of the overall gain. The sector’s rise was driven in part by strong returns for large pharmaceutical companies. Stocks of these firms returned to favor as investors grew more comfortable with how their managements are handling patent expirations of valuable products and a challenging regulatory environment. The energy sector was another highlight as integrated oil and gas companies benefited from the prospect that energy prices will stay high.

Financial stocks, which make up the second-largest sector in the index, declined overall during the period. Large diversified financial services firms saw a drop in revenues from trading and investments, while the big banks continued to wrestle with bad loans and other legacies of the deep recession.

Information technology stocks, the index’s largest sector, also lagged the broader market. The sector showed signs of strength in late 2010 as investors reacted to prospects for increased business spending and to consumers’ enthusiasm for new devices such as tablet computers. Some of that enthusiasm dissipated in the past six months, however, as the economic recovery appeared to stall while competition intensified among industry bellwethers.

Some age-old counsel for an unsettled era
Over the decades, our counsel to clients has remained consistent, even boring: Build a broadly diversified, low-cost portfolio that includes a mix of stock and bond funds and short-term investments consistent with your goals and circumstances. With its low costs and broad diversification, Vanguard 500 Index Fund, the world’s first index mutual fund for individual investors, can be an important component of such a plan.

Since the financial crisis, of course, a series of once-hard-to-imagine developments has reverberated through the global stock and bond markets. Is our simple, straightforward counsel still relevant? In a word, yes.

Impulsive portfolio changes can do damage to sensible long-term investment plans. A commitment to those plans, by contrast, has proven a reliable strategy for enhancing wealth. A recent Vanguard study of defined contribution plans found that, despite significant market shocks, participants, on average, had higher account balances in 2010 than in 2007, the eve of the financial crisis. The increase reflected the benefits of regular contributions, diversification, and the global stock markets’ rebound from crisis lows.

Thank you for entrusting your assets to Vanguard.

Sincerely,

F. William McNabb III
Chairman and Chief Executive Officer

500 Index Fund

Notes to Financial Statements

Vanguard 500 Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers four classes of shares: Investor Shares, Admiral Shares, Signal Shares, and ETF Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. Admiral Shares and Signal Shares are designed for investors who meet certain administrative, service, and account-size criteria. ETF Shares are listed for trading on the NYSE Arca, Inc.; they can be purchased and sold through a broker.

A. The following significant accounting policies conform to generally accepted accounting principles for U.S. mutual funds. The fund consistently follows such policies in preparing its financial statements.

1. Security Valuation: Securities are valued as of the close of trading on the New York Stock Exchange (generally 4 p.m., Eastern time) on the valuation date. Equity securities are valued at the latest quoted sales prices or official closing prices taken from the primary market in which each security trades; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Securities for which market quotations are not readily available, or whose values have been materially affected by events occurring before the fund’s pricing time but after the close of the securities’ primary markets, are valued by methods deemed by the board of trustees to represent fair value. Investments in Vanguard Market Liquidity Fund are valued at that fund’s net asset value. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value.

2. Futures Contracts: The fund uses index futures contracts to a limited extent, with the objectives of maintaining full exposure to the stock market, enhancing returns, maintaining liquidity, and minimizing transaction costs. The fund may purchase futures contracts to immediately invest incoming cash in the market, or sell futures in response to cash outflows, thereby simulating a fully invested position in the underlying index while maintaining a cash balance for liquidity. The fund may seek to enhance returns by using futures contracts instead of the underlying securities when futures are believed to be priced more attractively than the underlying securities. The primary risks associated with the use of futures contracts are imperfect correlation between changes in market values of stocks held by the fund and the prices of futures contracts, and the possibility of an illiquid market.

Futures contracts are valued at their quoted daily settlement prices. The aggregate principal amounts of the contracts are not recorded in the Statement of Net Assets. Fluctuations in the value of the contracts are recorded in the Statement of Net Assets as an asset (liability) and in the Statement of Operations as unrealized appreciation (depreciation) until the contracts are closed, when they are recorded as realized futures gains (losses).

3. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Management has analyzed the fund’s tax positions taken for all open federal income tax years (December 31, 2007–2010), and for the period ended June 30, 2011, and has concluded that no provision for federal income tax is required in the fund’s financial statements.

4. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

500 Index Fund

5. Security Lending: The fund may lend its securities to qualified institutional borrowers to earn additional income. Security loans are required to be secured at all times by collateral at least equal to the market value of securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability for the return of the collateral, during the period the securities are on loan. Security lending income represents fees charged to borrowers plus income earned on investing cash collateral, less expenses associated with the loan.

6. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

Each class of shares has equal rights as to assets and earnings, except that each class separately bears certain class-specific expenses related to maintenance of shareholder accounts (included in Management and Administrative expenses) and shareholder reporting. Marketing and distribution expenses are allocated to each class of shares based on a method approved by the board of trustees. Income, other non-class-specific expenses, and gains and losses on investments are allocated to each class of shares based on its relative net assets.

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At June 30, 2011, the fund had contributed capital of $17,419,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 6.97% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

Level 1—Quoted prices in active markets for identical securities.
Level 2—Other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.).
Level 3—Significant unobservable inputs (including the fund’s own assumptions used to determine the fair value of investments).

The following table summarizes the fund’s investments as of June 30, 2011, based on the inputs used to value them:

D. At June 30, 2011, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


				($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
S&P 500 Index	June 2011	547	179,895	4,668
E-mini S&P 500 Index	June 2011	550	36,176	1,293

Unrealized appreciation (depreciation) on open futures contracts is required to be treated as realized gain (loss) for tax purposes.

E. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes.

During the six months ended June 30, 2011, the fund realized $717,930,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at December 31, 2010, the fund had available capital loss carryforwards totaling $2,057,911,000 to offset future net capital gains of $293,941,000 through December 31, 2014, and $1,763,970,000 through December 31, 2016. In addition, the fund realized losses of $317,773,000 during the period from November 1, 2010, through December 31,2010, which are deferred and will be treated as realized for tax purposes in fiscal 2011. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending December 2011; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At June 30, 2011, the cost of investment securities for tax purposes was $75,861,667,000. Net unrealized appreciation of investment securities for tax purposes was $32,377,711,000, consisting of unrealized gains of $41,412,119,000 on securities that had risen in value since their purchase and $9,034,408,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the six months ended June 30, 2011, the fund purchased $3,534,653,000 of investment securities and sold $3,087,965,000 of investment securities, other than temporary cash investments.

About Your Fund’s Expenses

As a shareholder of the fund, you incur ongoing costs, which include costs for portfolio management, administrative services, and shareholder reports (like this one), among others. Operating expenses, which are deducted from a fund’s gross income, directly reduce the investment return of the fund.

A fund’s expenses are expressed as a percentage of its average net assets. This figure is known as the expense ratio. The following examples are intended to help you understand the ongoing costs (in dollars) of investing in your fund and to compare these costs with those of other mutual funds. The examples are based on an investment of $1,000 made at the beginning of the period shown and held for the entire period.

The accompanying table illustrates your fund’s costs in two ways:

• Based on actual fund return. This section helps you to estimate the actual expenses that you paid over the period. The ”Ending Account Value“ shown is derived from the fund‘s actual return, and the third column shows the dollar amount that would have been paid by an investor who started with $1,000 in the fund. You may use the information here, together with the amount you invested, to estimate the expenses that you paid over the period.

To do so, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number given for your fund under the heading ”Expenses Paid During Period.“

• Based on hypothetical 5% yearly return. This section is intended to help you compare your fund‘s costs with those of other mutual funds. It assumes that the fund had a yearly return of 5% before expenses, but that the expense ratio is unchanged. In this case—because the return used is not the fund’s actual return—the results do not apply to your investment. The example is useful in making comparisons because the Securities and Exchange Commission requires all mutual funds to calculate expenses based on a 5% return. You can assess your fund’s costs by comparing this hypothetical example with the hypothetical examples that appear in shareholder reports of other funds.

Note that the expenses shown in the table are meant to highlight and help you compare ongoing costs only and do not reflect transaction costs incurred by the fund for buying and selling securities. Further, the expenses do not include any purchase, redemption, or account service fees described in the fund prospectus. If such fees were applied to your account, your costs would be higher. Your fund does not carry a “sales load.”

The calculations assume no shares were bought or sold during the period. Your actual costs may have been higher or lower, depending on the amount of your investment and the timing of any purchases or redemptions.

You can find more information about the fund’s expenses, including annual expense ratios, in the Financial Statements section of this report. For additional information on operating expenses and other shareholder costs, please refer to your fund’s current prospectus.

Six Months Ended June 30, 2011


	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
500 Index Fund	12/31/2010	6/30/2011	Period
Based on Actual Fund Return
Investor Shares	$1,000.00	$1,059.52	$0.87
Admiral Shares	1,000.00	1,060.06	0.26
Signal Shares	1,000.00	1,059.99	0.26
ETF Shares	1,000.00	1,060.16	0.26
Based on Hypothetical 5% Yearly Return
Investor Shares	$1,000.00	$1,023.95	$0.85
Admiral Shares	1,000.00	1,024.55	0.25
Signal Shares	1,000.00	1,024.55	0.25
ETF Shares	1,000.00	1,024.55	0.25

The calculations are based on expenses incurred in the most recent six-month period. The fund’s annualized six-month expense ratios for that period are 0.17% for Investor Shares, 0.05% for Admiral Shares, 0.05% for Signal Shares, and 0.05% for ETF Shares. The dollar amounts shown as “Expenses Paid” are equal to the annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent six-month period, then divided by the number of days in the most recent 12-month period.

Trustees Approve Advisory Arrangement

The board of trustees of Vanguard 500 Index Fund has renewed the fund’s investment advisory arrangement with The Vanguard Group, Inc. Vanguard—through its Quantitative Equity Group—serves as the investment advisor for the fund. The board determined that continuing the fund’s internalized management structure was in the best interests of the fund and its shareholders.

The board based its decision upon an evaluation of the advisor’s investment staff, portfolio management process, and performance. The trustees considered the factors discussed below, among others. However, no single factor determined whether the board approved the arrangement. Rather, it was the totality of the circumstances that drove the board’s decision.

Nature, extent, and quality of services
The board considered the quality of the fund’s investment management over both the short and long term, and took into account the organizational depth and stability of the advisor. The board noted that Vanguard has been managing investments for more than three decades. The Quantitative Equity Group adheres to a sound, disciplined investment management process; the team has considerable experience, stability, and depth.

The board concluded that Vanguard’s experience, stability, depth, and performance, among other factors, warranted continuation of the advisory arrangement.

Investment performance
The board considered the short- and long-term performance of the fund, including any periods of outperformance or underperformance of its target index and peer group. The board concluded that the fund has performed in line with expectations, and that its results have been consistent with its investment strategies. Information about the fund’s most recent performance can be found in the Performance Summary section of this report.

Cost
The board concluded that the fund’s expense ratio was well below the average expense ratio charged by funds in its peer group and that the fund’s advisory fee rate was also well below its peer-group average. Information about the fund’s expenses appears in the About Your Fund’s Expenses section of this report as well as in the Financial Statements section.

The board does not conduct a profitability analysis of Vanguard because of Vanguard’s unique “at-cost” structure. Unlike most other mutual fund management companies, Vanguard is owned by the funds it oversees, and produces “profits” only in the form of reduced expenses for fund shareholders.

The benefit of economies of scale
The board concluded that the fund’s low-cost arrangement with Vanguard ensures that the fund will realize economies of scale as it grows, with the cost to shareholders declining as fund assets increase.

The board will consider whether to renew the advisory arrangement again after a one-year period.

Glossary

30-Day SEC Yield. A fund’s 30-day SEC yield is derived using a formula specified by the U.S. Securities and Exchange Commission. Under the formula, data related to the fund’s security holdings in the previous 30 days are used to calculate the fund’s hypothetical net income for that period, which is then annualized and divided by the fund’s estimated average net assets over the calculation period. For the purposes of this calculation, a security’s income is based on its current market yield to maturity (in the case of bonds) or its projected dividend yield (for stocks). Because the SEC yield represents hypothetical annualized income, it will differ—at times significantly—from the fund’s actual experience. As a result, the fund’s income distributions may be higher or lower than implied by the SEC yield.

Beta. A measure of the magnitude of a fund’s past share-price fluctuations in relation to the ups and downs of a given market index. The index is assigned a beta of 1.00. Compared with a given index, a fund with a beta of 1.20 typically would have seen its share price rise or fall by 12% when the index rose or fell by 10%. For this report, beta is based on returns over the past 36 months for both the fund and the index. Note that a fund’s beta should be reviewed in conjunction with its R-squared (see definition). The lower the R-squared, the less correlation there is between the fund and the index, and the less reliable beta is as an indicator of volatility.

Dividend Yield. Dividend income earned by stocks, expressed as a percentage of the aggregate market value (or of net asset value, for a fund). The yield is determined by dividing the amount of the annual dividends by the aggregate value (or net asset value) at the end of the period. For a fund, the dividend yield is based solely on stock holdings and does not include any income produced by other investments.

Earnings Growth Rate. The average annual rate of growth in earnings over the past five years for the stocks now in a fund.

Equity Exposure. A measure that reflects a fund’s investments in stocks and stock futures. Any holdings in short-term reserves are excluded.

Expense Ratio. The percentage of a fund’s average net assets used to pay its annual administrative and advisory expenses. These expenses directly reduce returns to investors.

Foreign Holdings. The percentage of a fund represented by securities or depositary receipts of companies based outside the United States.

Inception Date. The date on which the assets of a fund (or one of its share classes) are first invested in accordance with the fund’s investment objective. For funds with a subscription period, the inception date is the day after that period ends. Investment performance is measured from the inception date.

Median Market Cap. An indicator of the size of companies in which a fund invests; the midpoint of market capitalization (market price x shares outstanding) of a fund’s stocks, weighted by the proportion of the fund’s assets invested in each stock. Stocks representing half of the fund’s assets have market capitalizations above the median, and the rest are below it.

Price/Book Ratio. The share price of a stock divided by its net worth, or book value, per share. For a fund, the weighted average price/book ratio of the stocks it holds.

Price/Earnings Ratio. The ratio of a stock’s current price to its per-share earnings over the past year. For a fund, the weighted average P/E of the stocks it holds. P/E is an indicator of market expectations about corporate prospects; the higher the P/E, the greater the expectations for a company’s future growth.

R-Squared. A measure of how much of a fund’s past returns can be explained by the returns from the market in general, as measured by a given index. If a fund’s total returns were precisely synchronized with an index’s returns, its R-squared would be 1.00. If the fund’s returns bore no relationship to the index’s returns, its R-squared would be 0. For this report, R-squared is based on returns over the past 36 months for both the fund and the index.

Return on Equity. The annual average rate of return generated by a company during the past five years for each dollar of shareholder’s equity (net income divided by shareholder’s equity). For a fund, the weighted average return on equity for the companies whose stocks it holds.

Short-Term Reserves. The percentage of a fund invested in highly liquid, short-term securities that can be readily converted to cash.

Turnover Rate. An indication of the fund’s trading activity. Funds with high turnover rates incur higher transaction costs and may be more likely to distribute capital gains (which may be taxable to investors). The turnover rate excludes in-kind transactions, which have minimal impact on costs.

The People Who Govern Your Fund

The trustees of your mutual fund are there to see that the fund is operated and managed in your best interests since, as a shareholder, you are a part owner of the fund. Your fund’s trustees also serve on the board of directors of The Vanguard Group, Inc., which is owned by the Vanguard funds and provides services to them on an at-cost basis.

A majority of Vanguard’s board members are independent, meaning that they have no affiliation with Vanguard or the funds they oversee, apart from the sizable personal investments they have made as private individuals. The independent board members have distinguished backgrounds in business, academia, and public service. Each of the trustees and executive officers oversees 178 Vanguard funds.

The following table provides information for each trustee and executive officer of the fund. More information about the trustees is in the Statement of Additional Information, which can be obtained, without charge, by contacting Vanguard at 800-662-7447, or online at vanguard.com.

Chairman’s Letter

Dear Shareholder,

After a strong 2010, small-capitalization stocks remained a few steps ahead of the broader market through the first half of 2011. Vanguard Small-Cap Growth Index Fund was the top performer, returning about 10%. Vanguard Small-Cap Value Index Fund was the weakest, returning about 5%. The return of Vanguard Small-Cap Index Fund, a blend of growth and value stocks, was in the middle.

The returns of all three funds were in line with those of their benchmark indexes and superior to the average returns of their peer groups.

After the close of the period, we announced that in late September, the Small-Cap Growth and Value Index Funds will introduce low-cost Admiral Shares, part of Vanguard’s ongoing efforts to reduce the cost of investing. Admiral Shares are available to clients with a fund balance of $10,000 or more. (The Small-Cap Index Fund already offers Admiral Shares.) We expect the expense ratio for the growth fund’s Admiral Shares to be 0.10%; the value fund’s Admiral Shares are expected to have an expense ratio of 0.21%.

For stock markets, a ragged six-month gain
Global stock markets climbed unsteadily as investor attitudes swung from optimism about the strength of corporate earnings to fears that the slow, grinding recovery was losing momentum. Stock prices rallied through the first four months of 2011,

pulled back as economic news turned gloomier, then bounced back at the end of the period.

Small-cap strength was broad and deep
Despite the anxiety and pronounced volatility triggered by unsettling events on the global stage, the U.S. market’s small stocks produced strong six-month returns. The market’s—and corporate America’s— resilience was notable. With the exception of the financial stocks in Vanguard Small- Cap Value Index Fund, every sector of the small-cap market registered gains as corporate earnings continued to rebound from their recessionary depths.

The health care sector was a bright spot. Biotechnology stocks rallied on encouraging developments in companies’ product pipelines, while health care providers, which had languished through most of 2010, found renewed favor with investors. Small-cap information technology companies posted robust returns, spurred higher by a growing appetite for takeover activity among the technology industry’s cash-rich giants. Both sectors have relatively heavy weightings in Vanguard Small-Cap Growth Index Fund, which leaped past the Small-Cap and Small-Cap Value Index Funds for the period.

Energy stocks made big contributions to all three funds. Growing energy demand along with the prospect of higher energy prices was a key contributor to the double-digit returns in that sector.

The fund expense ratios shown are from the prospectus dated April 29, 2011, and represent estimated costs for the current fiscal year. For the six months ended June 30, 2011, the funds’ annualized expense ratios were: for the Small-Cap Index Fund, 0.25% for Investor Shares, 0.10% for Admiral Shares, 0.10% for Signal Shares, 0.08% for Institutional Shares, 0.06% for Institutional Plus Shares, and 0.11% for ETF Shares; for the Small-Cap Growth Index Fund, 0.24% for Investor Shares, 0.08% for Institutional Shares, and 0.10% for ETF Shares; and for the Small-Cap Value Index Fund, 0.24% for Investor Shares, 0.08% for Institutional Shares, and 0.10% for ETF Shares. The peer-group expense ratios are derived from data provided by Lipper Inc. and capture information through year-end 2010.

Peer groups: For the Small-Cap Index Fund, Small-Cap Core Funds; for the Small-Cap Growth Index Fund, Small-Cap Growth Funds; for the Small-Cap Value Index Fund, Small-Cap Value Funds.

Although weak spots were few, they were most visible in Vanguard Small-Cap Value Index Fund, which produced the lowest six-month return. Like its index, the fund held more than one-third of its assets in financial stocks. These holdings produced a slightly negative return as banks wrestled with bad loans, new regulatory developments, and other legacies of the deep recession.

All three funds captured the returns of their target indexes, a tribute to the funds’ advisor, Vanguard Quantitative Equity Group, whose skilled portfolio managers and traders have long distinguished themselves as the indexing experts in almost every segment of the public stock markets.

Some age-old counsel for an unsettled era
Over the decades, our counsel to clients has remained consistent, even boring: Build a broadly diversified, low- cost portfolio that includes a mix of stock and bond funds and short-term investments consistent with your goals and circumstances. With their low costs and broad diversification across the small-cap market, the Vanguard Small-Cap Index Funds can be important components of such a plan.

A note on expense ratios

The Expense Ratios table in each report’s Chairman’s Letter displays fund expense

ratios from the most recent prospectus. These figures include the funds’ actual

operating expenses. For some funds, the figures also include “acquired fund fees

and expenses,” which result from the funds’ holdings in business development

companies (BDCs).

Although the Securities and Exchange Commission requires that BDC costs be

included in a fund’s expense ratio, these fees are not incurred by the fund. They

have no impact on a fund’s total return or on its tracking error relative to an index.

A footnote to the Expense Ratios table reports an annualized calculation of the

fund’s actual expenses for the period, a more accurate tally of the operating costs

incurred by shareholders.

The fund offers six classes of shares: Investor Shares, Admiral Shares, Signal Shares, Institutional Shares, Institutional Plus Shares, and ETF Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. Admiral Shares, Signal Shares, Institutional Shares, and Institutional Plus Shares are designed for investors who meet certain administrative, service, and account-size criteria. ETF Shares are listed for trading on the NYSE Arca, Inc.; they can be purchased and sold through a broker.

4. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

Small-Cap Index Fund

Liquidity Fund, and records a liability for the return of the collateral, during the period the securities are on loan. Security lending income represents fees charged to borrowers plus income earned on investing cash collateral, less expenses associated with the loan.

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At June 30, 2011, the fund had contributed capital of $4,229,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 1.69% of Vanguard’s capitalization.

D. At June 30, 2011, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


				($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
E-mini Russell 2000 Index	September 2011	1,126	92,940	5,310

Unrealized appreciation (depreciation) on open futures contracts is required to be treated as realized gain (loss) for tax purposes.

During the six months ended June 30, 2011, the fund realized $1,282,574,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at December 31, 2010, the fund had available capital loss carryforwards totaling $2,405,922,000 to offset future net capital gains of $326,341,000 through December 31, 2011, $23,049,000 through December 31, 2015, $481,807,000 through December 31, 2016, $970,576,000 through December 31, 2017, and $604,149,000 through December 31, 2018. In addition, the fund realized losses of $104,033,000 during the period from November 1, 2010, through December 31, 2010, which are deferred and will be treated as realized for tax purposes in fiscal 2011. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending December 31, 2011; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At June 30, 2011, the cost of investment securities for tax purposes was $22,692,990,000. Net unrealized appreciation of investment securities for tax purposes was $3,783,183,000, consisting of unrealized gains of $5,643,160,000 on securities that had risen in value since their purchase and $1,859,977,000 in unrealized losses on securities that had fallen in value since their purchase.

The fund offers three classes of shares: Investor Shares, Institutional Shares, and ETF Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. Institutional Shares are designed for investors who meet certain administrative, service, and account-size criteria. ETF Shares are listed for trading on the NYSE Arca, Inc.; they can be purchased and sold through a broker.

4. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

Small-Cap Growth Index Fund

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At June 30, 2011, the fund had contributed capital of $1,513,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 0.61% of Vanguard’s capitalization.

D. At June 30, 2011, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


				($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
E-mini Russell 2000 Index	September 2011	274	22,616	956

Unrealized appreciation (depreciation) on open futures contracts is required to be treated as realized gain (loss) for tax purposes.

During the six months ended June 30, 2011, the fund realized $470,709,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at December 31, 2010, the fund had available capital loss carryforwards totaling $1,428,308,000 to offset future net capital gains of $13,814,000 through December 31, 2011, $15,893,000 through December 31, 2014, $12,561,000 through December 31, 2015, $302,440,000 through December 31, 2016, $822,482,000 through December 31, 2017, and $261,118,000 through December 31, 2018. In addition, the fund realized losses of $59,809,000 during the period from November 1, 2010, through December 31, 2010, which are deferred and will be treated as realized for tax purposes in fiscal 2011. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending December 31, 2011; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

Small-Cap Growth Index Fund

At June 30, 2011, the cost of investment securities for tax purposes was $7,780,562,000. Net unrealized appreciation of investment securities for tax purposes was $1,646,264,000, consisting of unrealized gains of $1,950,239,000 on securities that had risen in value since their purchase and $303,975,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the six months ended June 30, 2011, the fund purchased $3,690,398,000 of investment securities and sold $2,810,727,000 of investment securities, other than temporary cash investments.

Small-Cap Value Index Fund

Notes to Financial Statements

Vanguard Small-Cap Value Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers three classes of shares: Investor Shares, Institutional Shares, and ETF Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. Institutional Shares are designed for investors who meet certain administrative, service, and account-size criteria. ETF Shares are listed for trading on the NYSE Arca, Inc.; they can be purchased and sold through a broker.

4. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

Small-Cap Value Index Fund

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At June 30, 2011, the fund had contributed capital of $1,194,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 0.48% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

Temporary Cash Investments	27,495	850	—
Total	7,362,536	850	162

The following table summarizes changes in investments valued based on Level 3 inputs during the six months ended June 30, 2011:

Transfers into Level 3	162
Balance as of June 30, 2011	162

D. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes.

During the six months ended June 30, 2011, the fund realized $349,171,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at December 31, 2010, the fund had available capital loss carryforwards totaling $1,638,969,000 to offset future net capital gains of $67,032,000 through December 31, 2011, $86,085,000 through December 31, 2015, $318,931,000 through December 31, 2016, $778,148,000 through December 31, 2017, and $388,773,000 through December 31, 2018. In addition, the fund realized losses of $105,048,000 during the period from November 1, 2010, through December 31, 2010, which are deferred and will be treated as realized for tax purposes in fiscal 2011. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending December 31, 2011; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At June 30, 2011, the cost of investment securities for tax purposes was $6,678,346,000. Net unrealized appreciation of investment securities for tax purposes was $685,202,000, consisting of unrealized gains of $1,106,722,000 on securities that had risen in value since their purchase and $421,520,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the six months ended June 30, 2011, the fund purchased $2,151,732,000 of investment securities and sold $2,142,079,000 of investment securities, other than temporary cash investments.

About Your Fund’s Expenses

The accompanying table illustrates your fund’s costs in two ways:

Six Months Ended June 30, 2011


	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
	12/31/2010	6/30/2011	Period
Based on Hypothetical 5% Yearly Return
Small-Cap Index Fund
Investor Shares	$1,000.00	$1,023.55	$1.25
Admiral Shares	1,000.00	1,024.30	0.50
Signal Shares	1,000.00	1,024.30	0.50
Institutional Shares	1,000.00	1,024.40	0.40
Institutional Plus Shares	1,000.00	1,024.50	0.30
ETF Shares	1,000.00	1,024.25	0.55
Small-Cap Growth Index Fund
Investor Shares	$1,000.00	$1,023.60	$1.20
Institutional Shares	1,000.00	1,024.40	0.40
ETF Shares	1,000.00	1,024.30	0.50
Small-Cap Value Index Fund
Investor Shares	$1,000.00	$1,023.60	$1.20
Institutional Shares	1,000.00	1,024.40	0.40
ETF Shares	1,000.00	1,024.30	0.50

The calculations are based on expenses incurred in the most recent six-month period. The funds’ annualized six-month expense ratios for that period are: for the Small-Cap Index Fund, 0.25% for Investor Shares, 0.10% for Admiral Shares, 0.10% for Signal Shares, 0.08% for Institutional Shares, 0.06% for Institutional Plus Shares, and 0.11% for ETF Shares; for the Small-Cap Growth Index Fund, 0.24% for Investor Shares, 0.08% for Institutional Shares, and 0.10% for ETF Shares; and for the Small-Cap Value Index Fund, 0.24% for Investor Shares, 0.08% for Institutional Shares, and 0.10% for ETF Shares. The dollar amounts shown as “Expenses Paid” are equal to the annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent six-month period, then divided by the number of days in the most recent 12-month period.

Trustees Approve Advisory Arrangement

The board of trustees of Vanguard Small-Cap Index Fund, Small-Cap Growth Index Fund, and Small-Cap Value Index Fund has renewed the funds’ investment advisory arrangement with The Vanguard Group, Inc. Vanguard—through its Quantitative Equity Group—serves as the investment advisor for the funds. The board determined that continuing the funds’ internalized management structure was in the best interests of the funds and their shareholders.

Nature, extent, and quality of services
The board considered the quality of the funds’ investment management over both the short and long term, and took into account the organizational depth and stability of the advisor. The board noted that Vanguard has been managing investments for more than three decades. The Quantitative Equity Group adheres to a sound, disciplined investment management process; the team has considerable experience, stability, and depth.

The board concluded that Vanguard’s experience, stability, depth, and performance, among other factors, warranted continuation of the advisory arrangement.

Investment performance
The board considered the short- and long-term performance of the funds, including any periods of outperformance or underperformance of their target indexes and peer groups. The board concluded that the funds have performed in line with expectations, and that their results have been consistent with their investment strategies. Information about the funds’ most recent performance can be found on the Performance Summary pages of this report.

Cost
The board concluded that each fund’s expense ratio was well below the average expense ratio charged by funds in its peer group, and that the funds’ advisory fee rates were also well below their peer-group averages. Information about the funds’ expenses appears in the About Your Fund’s Expenses section of this report as well as in the Financial Statements sections.

The board does not conduct a profitability analysis of Vanguard because of Vanguard’s unique “at-cost” structure. Unlike most other mutual fund management companies, Vanguard is owned by the funds it oversees, and produces “profits” only in the form of reduced expenses for fund shareholders.

The benefit of economies of scale
The board concluded that the funds’ low-cost arrangement with Vanguard ensures that the funds will realize economies of scale as they grow, with the cost to shareholders declining as fund assets increase.

The board will consider whether to renew the advisory arrangement again after a one-year period.

Chairman’s Letter

Dear Shareholder,

Despite market gyrations in the face of dramatic global events, Vanguard’s four U.S. mid-capitalization index funds delivered strong returns for the six months ending June 30, ranging from more than 9% for Vanguard Mid-Cap Growth Index Fund to close to 7% for Vanguard Mid-Cap Value Index Fund. Returns for Vanguard Mid-Cap Index Fund and Vanguard Extended Market Index Fund, which hold a combination of growth and value stocks, fell in the middle of the range.

All four mid-cap funds closely tracked their respective benchmark indexes. While the Extended Market Index Fund return was in line with the 7.38% return of its peer group, the other three funds bested the average returns posted by their peers.

After the close of the period, we announced that in late September, the Mid-Cap Growth and Value Index Funds will introduce low-cost Admiral Shares, part of Vanguard’s ongoing efforts to reduce the cost of investing. (The other funds in this report already offer Admiral Shares.) Admiral shares are available to clients with a fund balance of $10,000 or more. We expect the expense ratio of the new shares to be 0.10%.

prices rallied through the first four months of 2011, pulled back as economic news turned gloomier, then bounced back at the end of the period.

Low yields, solid returns in the bond market
Bonds delivered solid six-month returns even as interest rates hovered near generational lows. Bond prices rallied in the spring as economic anxiety prompted a search for safer havens in fixed income. The broad taxable bond market returned almost 3%. The municipal market performed even better.

The yields on money market instruments remained nearly invisible, consistent with the Federal Reserve Board’s target for short-term interest rates, which since December 2008 has been anchored between 0% and 0.25%.

In a strong mid-cap market growth led value
The four mid-cap index funds finished the period a few steps ahead of the broad market. The Mid-Cap Growth Index Fund got a boost from its holdings in the consumer discretionary and health-care sectors. Consumer discretionary stocks, including media and textiles, apparel, and luxury goods holdings, posted double-digit returns as consumer spending held up in the face of higher food and energy costs. That sector also lifted the returns of the Mid-Cap Index Fund and the Extended Market Index Fund.

Health care buoyed the return of the Mid-Cap Growth Index Fund, thanks in part to the strength of the biotechnology industry. The Extended Market Index Fund also benefited from its biotechnology stocks, while the Mid-Cap Index Fund was powered by its holdings in health-care providers and services.

The return of the Mid-Cap Growth Index Fund was dampened by its heavy weighting in information technology, its second-largest sector exposure. The fund’s—and the index’s—communications equipment holdings lagged in the face of intense competition and technology spending cuts by state and local governments. The fund also paid a price for its relatively modest exposure to utilities, which posted strong returns as their healthy dividends appealed to investors facing low yields on many fixed income investments. The Mid-Cap Index Fund and the Extended Market Index Fund were also relatively light in utilities.

The weakest performer was the Mid-Cap Value Index Fund. While the fund benefited from its heavy concentration in utilities, its largest sector weighting was in financial stocks, which fared poorly as low trading volumes and asset prices hurt capital market stocks and weak loan and revenue growth hampered the performance of commercial banks. A significant concentration in information technology also detracted.

All four funds captured the returns of their target indexes, a tribute to the skilled portfolio management and sophisticated risk-control and trading systems of the funds’ advisor, Vanguard Quantitative Equity Group. The advisor was helped in this task by the funds’ low expense ratios.

Some age-old counsel for an unsettled time
Over the decades, our counsel to clients has remained consistent: Build a broadly diversified, low-cost portfolio that includes a mix of stock and bond funds and short-term investments consistent with your goals and circumstances.

Since the financial crisis, a series of once-hard-to-imagine developments has reverberated through the global stock and bond markets. Is our simple, straightforward counsel still relevant? In a word, yes.

Impulsive portfolio changes can damage sensible long-term investment plans. A commitment to those plans, by contrast, can help protect your assets from the markets’ inevitable ups and downs. A recent Vanguard study of defined- contribution plans found that, despite significant market shocks, participants, on average, had higher account balances in 2010 than in 2007, the eve of the financial crisis. The increase reflected the benefits of regular contributions, diversification, and the global stock markets’ rebound from crisis lows. For investors seeking exposure to midsize companies in the U.S. stock market, Vanguard’s mid-cap index funds can be a valuable component of a balanced portfolio.

Thank you for entrusting your assets to Vanguard.

Sincerely,

F. William McNabb III
Chairman and Chief Executive Officer
July 25, 2011

A note on expense ratios

The Expense Ratios table in each report’s Chairman’s Letter displays fund expense

ratios from the most recent prospectus. These figures include the funds’ actual

operating expenses. For some funds, the figures also include “acquired fund fees

and expenses,” which result from the funds’ holdings in business development

companies (BDCs).

Although the Securities and Exchange Commission requires that BDC costs be

included in a fund’s expense ratio, these fees are not incurred by the fund. They

have no impact on a fund’s total return or on its tracking error relative to an index.

A footnote to the Expense Ratios table reports an annualized calculation of the

fund’s actual expenses for the period, a more accurate tally of the operating costs

incurred by shareholders.

D. At June 30, 2011, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


				($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation

E-mini S&P MidCap 400 Index	September 2011	227	22,167	924
E-mini Russell 2000 Index	September 2011	234	19,314	1,023

Unrealized appreciation (depreciation) on open futures contracts is required to be treated as realized gain (loss) for tax purposes.

During the six months ended June 30, 2011, the fund realized $187,938,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at December 31, 2010, the fund had available capital loss carryforwards totaling $1,684,629,000 to offset future net capital gains of $100,407,000 through December 31, 2011, $60,375,000 through December 31, 2014, $168,517,000 through December 31, 2015, $708,199,000 through December 31, 2016, $622,547,000 through December 31, 2017, and $24,584,000 through December 31, 2018. In addition, the fund realized losses of $1,466,000 during the period from November 1, 2010, through December 31, 2010, which are deferred and will be treated as realized for tax purposes in fiscal 2011. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending December 31, 2011; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

Extended Market Index Fund

At June 30, 2011, the cost of investment securities for tax purposes was $16,589,473,000. Net unrealized appreciation of investment securities for tax purposes was $3,764,527,000, consisting of unrealized gains of $5,265,652,000 on securities that had risen in value since their purchase and $1,501,125,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the six months ended June 30, 2011, the fund purchased $3,094,129,000 of investment securities and sold $1,543,221,000 of investment securities, other than temporary cash investments.

D. At June 30, 2011, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


				($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
E-mini S&P MidCap Index	September 2011	80	7,812	355

Unrealized appreciation (depreciation) on open futures contracts is required to be treated as realized gain (loss) for tax purposes.

During the six months ended June 30, 2011, the fund realized $626,661,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at December 31, 2010, the fund had available capital loss carryforwards totaling $3,627,445,000 to offset future net capital gains of $14,378,000 through December 31, 2011, $63,490,000 through December 31, 2014, $1,194,245,000 through December 31, 2016, $1,793,234,000 through December 31, 2017, and $562,098,000 through December 31, 2018. In addition, the fund realized losses of $158,499,000 during the period from November 1, 2010, through December 31, 2010, which are deferred and will be treated as realized for tax purposes in fiscal 2011. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending December 31, 2011; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At June 30, 2011, the cost of investment securities for tax purposes was $24,223,006,000. Net unrealized appreciation of investment securities for tax purposes was $5,429,130,000, consisting of unrealized gains of $6,734,081,000 on securities that had risen in value since their purchase and $1,304,951,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the six months ended June 30, 2011, the fund purchased $5,634,622,000 of investment securities and sold $4,201,850,000 of investment securities, other than temporary cash investments.

Mid-Cap Growth Index Fund

Notes to Financial Statements

Vanguard Mid-Cap Growth Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares: Investor Shares and ETF Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. ETF Shares are listed for trading on the NYSE Arca, Inc.; they can be purchased and sold through a broker.

2. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Management has analyzed the fund’s tax positions taken for all open federal income tax years (December 31, 2007–2010), and for the period ended June 30, 2011, and has concluded that no provision for federal income tax is required in the fund’s financial statements.

3. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

4. Security Lending: The fund may lend its securities to qualified institutional borrowers to earn additional income. Security loans are required to be secured at all times by collateral at least equal to the market value of securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability for the return of the collateral, during the period the securities are on loan. Security lending income represents fees charged to borrowers plus income earned on investing cash collateral, less expenses associated with the loan.

5. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

Mid-Cap Growth Index Fund

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At June 30, 2011, the fund had contributed capital of $401,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 0.16% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

At June 30, 2011, 100% of the fund’s investments were valued based on Level 1 inputs.

During the six months ended June 30, 2011, the fund realized $101,961,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at December 31, 2010, the fund had available capital loss carryforwards totaling $398,186,000 to offset future net capital gains of $35,000 through December 31, 2014, $480,000 through December 31, 2015, $48,884,000 through December 31, 2016, $265,769,000 through December 31, 2017, and $83,018,000 through December 31, 2018. In addition, the fund realized losses of $5,204,000 during the period from November 1, 2010, through December 31, 2010, which are deferred and will be treated as realized for tax purposes in fiscal 2011. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending December 31, 2011; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At June 30, 2011, the cost of investment securities for tax purposes was $2,094,225,000. Net unrealized appreciation of investment securities for tax purposes was $400,011,000, consisting of unrealized gains of $451,566,000 on securities that had risen in value since their purchase and $51,555,000 in unrealized losses on securities that had fallen in value since their purchase.

Mid-Cap Growth Index Fund

E. During the six months ended June 30, 2011, the fund purchased $1,124,289,000 of investment securities and sold $819,594,000 of investment securities, other than temporary cash investments.

F. Capital share transactions for each class of shares were:

ETF Shares are listed for trading on the NYSE Arca, Inc.; they can be purchased and sold through a broker.

3. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At June 30, 2011, the fund had contributed capital of $267,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 0.11% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

Mid-Cap Value Index Fund

C. Various inputs may be used to determine the value of the fund’s investments. These inputs are summarized in three broad levels for financial statement purposes. The inputs or methodologies used to value securities are not necessarily an indication of the risk associated with investing in those securities.

Level 1—Quoted prices in active markets for identical securities.
Level 2—Other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.).
Level 3—Significant unobservable inputs (including the fund’s own assumptions used to determine the fair value of investments).

At June 30, 2011, 100% of the fund’s investments were valued based on Level 1 inputs.

During the six months ended June 30, 2011, the fund realized $46,101,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at December 31, 2010, the fund had available capital loss carryforwards totaling $237,495,000 to offset future net capital gains of $11,000 through December 31, 2014, $390,000 through December 31, 2015, $47,840,000 through December 31, 2016, $125,799,000 through December 31, 2017, and $63,455,000 through December 31, 2018. In addition, the fund realized losses of $8,006,000 during the period from November 1, 2010, through December 31, 2010, which are deferred and will be treated as realized for tax purposes in fiscal 2011. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending December 31, 2011; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At June 30, 2011, the cost of investment securities for tax purposes was $1,444,823,000. Net unrealized appreciation of investment securities for tax purposes was $214,346,000, consisting of unrealized gains of $245,804,000 on securities that had risen in value since their purchase and $31,458,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the six months ended June 30, 2011, the fund purchased $590,747,000 of investment securities and sold $452,457,000 of investment securities, other than temporary cash investments.

The calculations are based on expenses incurred in the most recent six-month period. The funds’ annualized six-month expense ratios for that period are: for the Extended Market Index Fund, 0.24% for Investor Shares, 0.10% for Admiral Shares, 0.10% for Signal Shares, 0.08% for Institutional Shares, and 0.10% for ETF Shares; for the Mid-Cap Index Fund, 0.25% for Investor Shares, 0.10% for Admiral Shares, 0.10% for Signal Shares, 0.08% for Institutional Shares, 0.06% for Institutional Plus Shares, and 0.10% for ETF Shares; for the Mid-Cap Growth Index Fund, 0.24% for Investor Shares and 0.10% for ETF Shares; and for the Mid-Cap Value Index Fund, 0.24% for Investor Shares and 0.10% for ETF Shares. The dollar amounts shown as “Expenses Paid” are equal to the annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent six-month period, then divided by the number of days in the most recent 12-month period. This table does not include data for funds or share classes of funds with fewer than six months of history.

Trustees Approve Advisory Arrangement

The board of trustees of Vanguard Extended Market Index Fund, Mid-Cap Index Fund, Mid-Cap Growth Index Fund, and Mid-Cap Value Index Fund has renewed the funds’ investment advisory arrangement with The Vanguard Group, Inc. Vanguard—through its Quantitative Equity Group—serves as the investment advisor for the funds. The board determined that continuing the funds’ internalized management structure was in the best interests of the funds and their shareholders.

Nature, extent, and quality of services
The board considered the quality of the funds’ investment management over both the short and long term, and took into account the organizational depth and stability of the advisor. The board noted that Vanguard has been managing investments for more than three decades. The Quantitative Equity Group adheres to a sound, disciplined investment management process; the team has considerable experience, stability, and depth.

The board concluded that Vanguard’s experience, stability, depth, and performance, among other factors, warranted continuation of the advisory arrangement.

Investment performance
The board considered the short- and long-term performance of the funds, including any periods of outperformance or underperformance of their target indexes and peer groups. The board concluded that the funds have performed in line with expectations, and that their results have been consistent with their investment strategies. Information about the funds’ most recent performance can be found on the Performance Summary pages of this report.

Cost
The board concluded that each fund’s expense ratio was well below the average expense ratio charged by funds in its peer group and that the funds’ advisory fee rates were also well below their peer-group averages. Information about the funds’ expenses appears in the About Your Fund’s Expenses section of this report as well as in the Financial Statements sections.

The board does not conduct a profitability analysis of Vanguard because of Vanguard’s unique “at-cost” structure. Unlike most other mutual fund management companies, Vanguard is owned by the funds it oversees, and produces “profits” only in the form of reduced expenses for fund shareholders.

The benefit of economies of scale
The board concluded that the funds’ low-cost arrangement with Vanguard ensures that the funds will realize economies of scale as they grow, with the cost to shareholders declining as fund assets increase.

The board will consider whether to renew the advisory arrangement again after a one-year period.

Chairman’s Letter

Dear Shareholder,

Vanguard’s trio of large-capitalization U.S. index funds delivered solid performances for the six months ended June 30, 2011, posting returns ranging from 5.90% for Vanguard Growth Index Fund to 6.33% for Vanguard Value Index Fund. Vanguard Large-Cap Index Fund, which invests in both value and growth stocks, fell in the middle of the pack, returning 6.11% for the half-year. (All returns are for the funds’ Investor Shares.)

The performances of all three funds closely tracked those of their respective target indexes and bested the average returns of their peer groups for the period.

For stock markets, a ragged six-month gain
Global stock markets climbed unsteadily as investor attitudes swung from giddy optimism about the strength of corporate earnings to fears that the slow, grinding recovery was losing momentum. Stock prices rallied through the first four months of 2011, pulled back as economic news turned gloomier, then bounced back at the end of the period.

Low yields, solid returnsin the bond market
Bonds delivered solid six-month returns even as interest rates hovered near generational lows. Bond prices rallied in spring as economic anxiety prompted a search for safer havens in fixed income. The broad taxable bond market returned almost 3%. The municipal market performed even better. Municipal securities were hammered early in the year as unsettling headlines raised doubts about their safety. Toward the end, investors’ worries began to recede and prices rose.

Value stocks outperformed during uncertain times
Vanguard’s three large-cap index funds posted solid returns for the fiscal half-year ended June 30. During the period, value stocks outperformed growth stocks, giving a slight advantage to the Value Index Fund, which was the trio’s top performer for the period. Returns for the Large-Cap Index Fund, which consists of both value and growth stocks, fell between those of the other two funds. Although the Growth Index Fund was the laggard of the group, the fund posted gains in all ten market sectors for the period.

All three funds generally saw similar results on a sector level. Overall, stocks performed well and all sectors—-with the exception of financials in the Value Index and Large-Cap Index Funds—-gained for the period. Battered investment and commercial banks weighed heaviest on the two funds’ performances. The Growth Index Fund’s holdings in the sector fared better and generated a positive return.

Stocks in the health care, energy, and consumer discretionary sectors contributed significantly to returns. Health care, the market’s top performer for the six months, lagged early in the period, but bounced back in the final weeks as investors looked to the sector for stability amid rising concerns over economic uncertainty. Health care stocks were mostly positive across the board, with pharmaceuticals, biotechnology firms, and health care providers leading the way.

Energy stocks were also significant contributors to the funds’ six-month returns. The sector was led by oil and gas companies, as oil prices remained high throughout the period. The consumer discretionary sector was also a strong performer, with stocks of media companies and restaurants among the top contributors. Stocks within the industrials and consumer staples sectors also helped boost returns.

Throughout the six-month period, each fund closely tracked its respective benchmark. Such close index-tracking performance is a tribute to the funds’ advisor, Vanguard Quantitative Equity Group, which employs skilled portfolio management and sophisticated risk-control and trading systems in its efforts. The advisor was helped in this task by the funds’ low expense ratios.

Focus on your goals, not the market’s ups and downs
The stock market turned in solid results for the most recent six months. But the financial markets are unpredictable, and nobody knows what the next six months will bring. Good or bad, there will always be unexpected news that drives global stock markets up or down.

At Vanguard, we believe that the best way to deal with the market’s uncertainty is to ignore short-term volatility and, instead, focus on the long term. We urge investors to create a balanced investment plan that includes a mix of stock, bond, and money market funds appropriate for their goals and risk tolerance—and to stick with that plan regardless of market conditions.

Vanguard’s large-cap index funds can help to diversify such a balanced long-term investment portfolio by providing exposure to the large-cap segment of the U.S. stock market—both the segment as a whole and its growth and value components. Each fund offers a low-cost way to invest in some of the United States’ biggest companies.

Thank you for entrusting your assets to Vanguard.

Sincerely,

F. William McNabb III
Chairman and Chief Executive Officer
July 12, 2011

Growth Index Fund

Notes to Financial Statements

Vanguard Growth Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers five classes of shares: Investor Shares, Admiral Shares, Signal Shares, Institutional Shares, and ETF Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. Admiral Shares, Signal Shares, and Institutional Shares are designed for investors who meet certain administrative, service, and account-size criteria. ETF Shares are listed for trading on the NYSE Arca, Inc.; they can be purchased and sold through a broker.

3. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

Growth Index Fund

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At June 30, 2011, the fund had contributed capital of $3,375,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 1.35% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

At June 30, 2011, 100% of the fund’s investments were valued based on Level 1 inputs.

During the six months ended June 30, 2011, the fund realized $18,010,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

Value Index Fund

Notes to Financial Statements

Vanguard Value Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers five classes of shares: Investor Shares, Admiral Shares, Signal Shares, Institutional Shares, and ETF Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. Admiral Shares, Signal Shares, and Institutional Shares are designed for investors who meet certain administrative, service, and account-size criteria. ETF Shares are listed for trading on the NYSE Arca, Inc.; they can be purchased and sold through a broker.

3. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

Value Index Fund

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At June 30, 2011, the fund had contributed capital of $2,515,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 1.01% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

At June 30, 2011, 100% of the fund’s investments were valued based on Level 1 inputs.

During the six months ended June 30, 2011, the fund realized $18,523,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at December 31,2010, the fund had available capital loss carryforwards totaling $2,510,548,000 to offset future net capital gains of $188,450,000 through December 31, 2011, $40,920,000 through December 31, 2014, $73,605,000 through December 31, 2015, $574,313,000 through December 31, 2016 and $1,633,260,000 through December 31, 2017. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending December 31, 2011; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At June 30, 2011, the cost of investment securities for tax purposes was $14,964,498,000. Net unrealized appreciation of investment securities for tax purposes was $752,853,000, consisting of unrealized gains of $1,988,888,000 on securities that had risen in value since their purchase and $1,236,035,000 in unrealized losses on securities that had fallen in value since their purchase.

Value Index Fund

E. During the six months ended June 30, 2011, the fund purchased $2,807,674,000 of investment securities and sold $2,035,842,000 of investment securities, other than temporary cash investments.

F. Capital share transactions for each class of shares were:

Large-Cap Index Fund

Notes to Financial Statements

Vanguard Large-Cap Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers five classes of shares: Investor Shares, Admiral Shares, Signal Shares, Institutional Shares, and ETF Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. Admiral Shares, Signal Shares, and Institutional Shares are designed for investors who meet certain administrative, service, and account-size criteria. ETF Shares are listed for trading on the NYSE Arca, Inc.; they can be purchased and sold through a broker.

4. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

Large-Cap Index Fund

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At June 30, 2011, the fund had contributed capital of $827,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 0.33% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

D. At June 30, 2011, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


				($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
S&P 500 Index	September 2011	13	4,275	110
E-mini S&P 500 Index	September 2011	14	921	12

Unrealized appreciation (depreciation) on open futures contracts is required to be treated as realized gain (loss) for tax purposes.

During the six months ended June 30, 2011, the fund realized $30,130,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at December 31, 2010, the fund had available capital loss carryforwards totaling $201,206,000 to offset future net capital gains of $11,000 through December 31, 2013, $463,000 through December 31, 2014, $1,570,000 through December 31, 2015, $48,005,000 through December 31, 2016, $117,390,000 through December 31, 2017, and $33,767,000 through December 31, 2018. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending December 31, 2011; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At June 30, 2011, the cost of investment securities for tax purposes was $4,637,089,000. Net unrealized appreciation of investment securities for tax purposes was $691,860,000, consisting of unrealized gains of $954,418,000 on securities that had risen in value since their purchase and $262,558,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the six months ended June 30, 2011, the fund purchased $776,472,000 of investment securities and sold $224,120,000 of investment securities, other than temporary cash investments.

About Your Fund’s Expenses

The accompanying table illustrates your fund’s costs in two ways:


Six Months Ended June 30, 2011
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
	12/31/2010	6/30/2011	Period
Based on Hypothetical 5% Yearly Return

Institutional Shares	1,000.00	1,024.40	0.40
ETF Shares	1,000.00	1,024.30	0.50
Large-Cap Index Fund
Investor Shares	$1,000.00	$1,023.60	$1.20
Admiral Shares	1,000.00	1,024.30	0.50
Signal Shares	1,000.00	1,024.30	0.50
Institutional Shares	1,000.00	1,024.40	0.40
ETF Shares	1,000.00	1,024.30	0.50

The calculations are based on expenses incurred in the most recent six-month period. The funds’ annualized six-month expense ratios for that period are: for the Growth Index Fund, 0.25% for Investor Shares, 0.10% for Admiral Shares, 0.10% for Signal Shares, 0.08% for Institutional Shares, and 0.10% for ETF Shares; for the Value Index Fund, 0.25% for Investor Shares, 0.10% for Admiral Shares, 0.10% for Signal Shares, 0.08% for Institutional Shares, and 0.10% for ETF Shares; and for the Large-Cap Index Fund, 0.24% for Investor Shares, 0.10% for Admiral Shares, 0.10% for Signal Shares, 0.08% for Institutional Shares, and 0.10% for ETF Shares. The dollar amounts shown as “Expenses Paid” are equal to the annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent six-month period, then divided by the number of days in the most recent 12-month period.

Trustees Approve Advisory Arrangement

The board of trustees of Vanguard Growth Index Fund, Value Index Fund, and Large-Cap Index Fund has renewed the funds’ investment advisory arrangement with The Vanguard Group, Inc. Vanguard—through its Quantitative Equity Group—serves as the investment advisor for the funds. The board determined that continuing the funds’ internalized management structure was in the best interests of the funds and their shareholders.

Nature, extent, and quality of services
The board considered the quality of the funds’ investment management over both the short and long term, and took into account the organizational depth and stability of the advisor. The board noted that Vanguard has been managing investments for more than three decades. The Quantitative Equity Group adheres to a sound, disciplined investment management process; the team has considerable experience, stability, and depth.

The board concluded that Vanguard’s experience, stability, depth, and performance, among other factors, warranted continuation of the advisory arrangement.

Investment performance
The board considered the short- and long-term performance of the funds, including any periods of outperformance or underperformance of their target indexes and peer groups. The board concluded that the funds have performed in line with expectations, and that their results have been consistent with their investment strategies. Information about the funds’ most recent performance can be found on the Performance Summary pages of this report.

Cost
The board concluded that each fund’s expense ratio was well below the average expense ratio charged by funds in its peer group and that the funds’ advisory fee rates were also well below their peer-group averages. Information about the funds’ expenses appears in the About Your Fund’s Expenses section of this report as well as in the Financial Statements sections.

The board does not conduct a profitability analysis of Vanguard because of Vanguard’s unique “at-cost” structure. Unlike most other mutual fund management companies, Vanguard is owned by the funds it oversees, and produces “profits” only in the form of reduced expenses for fund shareholders.

The benefit of economies of scale
The board concluded that the funds’ low-cost arrangement with Vanguard ensures that the funds will realize economies of scale as they grow, with the cost to shareholders declining as fund assets increase.

The board will consider whether to renew the advisory arrangement again after a one-year period.

Chairman’s Letter

Dear Shareholder,

For the six months ended June 30, Investor Shares of Vanguard Total Stock Market Index Fund returned 6.31%, closely tracking the target MSCI US Broad Market Index and outperforming the average return of peer funds.

The fund posted positive results in nine of ten sectors, with health care and energy stocks contributing most significantly. Only the financial sector recorded a loss.

Health care and energy stocks led the fund’s returns
Vanguard Total Stock Market Index Fund is designed to provide investors with exposure to the entire U.S. equity market, including small-, mid-, and large-cap growth and value stocks. Although the fund (like the market itself) is more heavily weighted in large-caps, its limited exposure to mid- and small-cap stocks—which outperformed their larger counterparts for the period— helped boost returns.

On a sector basis, the fund’s performance was led by holdings in health care and energy. Health care—the market’s top

performer for the six months—lagged early on but bounced back later on as investors looked to the sector for stability amid rising concerns over economic uncertainty. These stocks generally gained across the industry, with pharmaceuticals and health care providers leading the way.

Despite signs of a weakening global economy, crude oil prices remained high, boosting stocks within the energy sector. Oil and gas companies added the most to fund returns. Consumer discretionary and industrial stocks also contributed significantly to the fund’s six-month performance.

As I noted earlier, the financial sector—which accounted for about 16% of fund holdings, on average—ended the period in negative territory. Battered investment and commercial banks weighed heaviest on performance.

The fund closely tracked its target index, as it has done since its inception in 1992 (a ten-year track record is in the Performance Summary, later in this report). Such tight tracking is a credit to the advisor, Vanguard Quantitative Equity Group, which combines skilled portfolio management with sophisticated risk-control and trading systems. The fund’s low expense ratio is important as well.

Focus on your goals rather than the market’s swings
The stock market turned in solid results for the six months just ended. But the financial markets are unpredictable, and nobody

knows what the next six months will bring. Good or bad, there will always be unexpected news that drives returns up or down.

At Vanguard, we believe that the best way to deal with this uncertainty is to ignore short-term volatility and, instead, focus on the long term. We urge investors to create an investment plan that includes a mix of stock, bond, and money market funds that is appropriate for their goals and risk tolerance—and to stick with that plan regardless of market conditions.

By offering broad, low-cost exposure to all segments of the U.S. stock market, Vanguard Total Stock Market Index Fund can serve as a cornerstone in your long-term investment plan.

As always, thank you for entrusting your assets to Vanguard.

Sincerely,

F. William McNabb III
Chairman and Chief Executive Officer

A note on expense ratios

The Expense Ratios table in each report’s Chairman’s Letter displays fund expense

ratios from the most recent prospectus. These figures include the funds’ actual

operating expenses. For some funds, the figures also include “acquired fund fees

and expenses,” which result from the funds’ holdings in business development

companies (BDCs).

Although the Securities and Exchange Commission requires that BDC costs be

included in a fund’s expense ratio, these fees are not incurred by the fund. They

have no impact on a fund’s total return or on its tracking error relative to an index.

A footnote to the Expense Ratios table reports an annualized calculation of the fund’s

actual expenses for the period, a more accurate tally of the operating costs incurred

by shareholders.

D. At June 30, 2011, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


				($000)
			Aggregate

E-mini S&P MidCap 400 Index	September 2011	280	27,342	1,070

Unrealized appreciation (depreciation) on open futures contracts is required to be treated as realized gain (loss) for tax purposes.

During the six months ended June 30, 2011, the fund realized $1,052,275,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at December 31, 2010, the fund had available capital loss carryforwards totaling $2,492,045,000 to offset future net capital gains of $209,043,000 through December 31, 2013, $19,516,000 through December 31, 2015, and $2,263,486,000 through December 31, 2016. In addition, the fund realized losses of $169,635,000 during the period from November 1, 2010, through December 31, 2010, which are deferred and will be treated as realized for tax purposes in fiscal 2011. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending December 31, 2011; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

Total Stock Market Index Fund

At June 30, 2011, the cost of investment securities for tax purposes was $144,819,171,000. Net unrealized appreciation of investment securities for tax purposes was $24,137,586,000, consisting of unrealized gains of $36,865,715,000 on securities that had risen in value since their purchase and $12,728,129,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the six months ended June 30, 2011, the fund purchased $14,619,367,000 of investment securities and sold $4,773,561,000 of investment securities, other than temporary cash investments.

About Your Fund’s Expenses

The accompanying table illustrates your fund’s costs in two ways:


Six Months Ended June 30, 2011
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
Total Stock Market Index Fund	12/31/2010	6/30/2011	Period
Based on Actual Fund Return

Admiral Shares	1,000.00	1,063.39	0.26
Signal Shares	1,000.00	1,063.37	0.26
Institutional Shares	1,000.00	1,063.74	0.26
ETF Shares	1,000.00	1,063.38	0.26
Based on Hypothetical 5% Yearly Return
Investor Shares	$1,000.00	$1,023.95	$0.85
Admiral Shares	1,000.00	1,024.55	0.25
Signal Shares	1,000.00	1,024.55	0.25
Institutional Shares	1,000.00	1,024.55	0.25
ETF Shares	1,000.00	1,024.55	0.25

The calculations are based on expenses incurred in the most recent six-month period. The fund’s annualized six-month expense ratios for that period are: 0.17% for Investor Shares, 0.05% for Admiral Shares, 0.05% for Signal Shares, 0.05% for Institutional Shares, and 0.05% for ETF Shares. The dollar amounts shown as “Expenses Paid” are equal to the annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent six-month period, then divided by the number of days in the most recent 12-month period.

The board of trustees of Vanguard Total Stock Market Index Fund has renewed the fund’s investment advisory arrangement with The Vanguard Group, Inc. Vanguard—through its Quantitative Equity Group—serves as the investment advisor for the fund.
