Chairman’s Letter

Dear Shareholder,

Global financial markets took a roller-coaster ride during 2010. Still, despite many ups and downs, Vanguard 500 Index Fund returned about 15% for the period, closely tracking its benchmark, the Standard & Poor’s 500 Index. The fund outperformed the average return of its large-capitalization core fund peers, which stood at about 13% for the year.

In September, Vanguard launched a suite of index mutual funds and exchange-traded funds based on the S&P domestic stock benchmarks. Vanguard S&P 500 ETF, which offers exchange-traded shares of Vanguard’s 500 Index Fund, is among the new offerings. The ETF Shares returned just under 16% for the brief period since their inception.

Please note that on October 6, Vanguard broadened the availability of our lower-cost Admiral Shares. We reduced the Admiral minimums on most of our broad-market index funds to $10,000 from $100,000, as part of our ongoing efforts to lower the cost of investing for our clients.

Although Vanguard 500 Index Fund posted impressive results for the year, it made no capital gains distributions—a benefit to shareholders in taxable accounts. You may wish to review the fund’s after-tax returns that appear later in this report.

Stocks rallied as the forecast seemed to brighten
After a series of false starts, hesitations, and retreats, global stock markets finished 2010 with powerful gains. As the prospect of a double-dip recession faded, the broad U.S. stock market clambered higher, shrugging off high unemployment and distress in Europe’s debt markets to return 17.70%. Small- and mid-capitalization stocks did even better.

Outside the United States, gains were more muted, in part because Europe’s sovereign debt challenges continued to reverberate through local stock markets. Emerging markets were the best performers. Asia’s developed markets performed weakly, though the strength of the yen, the Australian dollar, and other regional currencies bolstered returns for U.S.-based investors.

The fixed income market reprised a familiar theme
Although U.S. Treasury securities rallied through the summer, total return tables were dominated by riskier bonds for the full 12 months, a pattern we also saw in 2009. Low interest rates and a sense that the economic recovery was gathering momentum prompted investors to seek higher yields in both high-quality and below-investment-grade corporate bonds. The broad U.S. bond market returned 6.54%. Late in the year, yields bounced

off summer lows, putting pressure on bond prices. The dynamic was especially pronounced among municipal bonds.

As it has since December 2008, the Federal Reserve Board held its target for short-term interest rates near 0%, keeping the returns available from money market instruments such as the 3-month Treasury bill in the same neighborhood.

Gains in all sectors boosted fund returns
During 2010, the S&P 500 Index, a barometer of the market’s larger stocks, hit some rough spots, but it managed to post an impressive return of about 15% for the year. Your fund’s advisor, Vanguard Quantitative Equity Group, closely tracked the index’s performance, consistent with its long tradition of superior index fund management. The market’s recovery was broad-based, and all ten market sectors posted gains for the year.

The consumer discretionary sector was the index’s top performer for the period, gaining almost 28%. Improved consumer sentiment helped boost consumer stocks across the board, including holdings in media conglomerates, hotels, and restaurants. Retailers benefited from a better-than-expected back-to-school season and signs that shoppers were opening their wallets as the holidays approached.

	Investor	Admiral	Signal	ETF	Peer Group
	Shares	Shares	Shares	Shares	Average
500 Index Fund	0.18%	0.07%	0.07%	0.06%	1.27%

The fund expense ratios shown are from the prospectus dated September 7, 2010, for the ETF share class and April 29, 2010, for the Investor, Admiral, and Signal share classes and represent estimated costs for the current fiscal year. For the fiscal year ended December 31, 2010, the fund’s expense ratios were 0.17% for Investor Shares, 0.06% for Admiral Shares, 0.06% for Signal Shares, and 0.06% (annualized) for ETF Shares. The peer-group expense ratio is derived from data provided by Lipper Inc. and captures information through year-end 2009.

Peer group: Large-Cap Core Funds.

Stocks in the industrials sector also helped, returning almost 27% for the year. Equipment and machinery companies rose on high demand from emerging markets, most notably China, India, and Latin American countries.

Your fund benefited from double-digit gains in the energy and financial sectors. In energy, an increase in oil prices boosted gas companies while insurance companies, commercial banks, and real estate investment trusts led the way in financials. Returns from stocks in the information technology and consumer staples sectors also helped returns.

Long-term performance has been competitive
For the decade ended December 31, Investor Shares of 500 Index Fund generated an average annual return of 1.31%. These results were in line with those of the fund’s unmanaged benchmark, the S&P 500 Index, which has no transaction costs or operating expenses. The fund outperformed the –0.09% average annual result posted by its large-cap core fund peers for the same period. The peer group is mostly made up of actively managed funds, whose higher expenses are a drag on performance.

The figures shown represent past performance, which is not a guarantee of future results. (Current performance may be lower or higher than the performance data cited. For performance data current to the most recent month-end, visit our website at vanguard.com/performance.) Note, too, that both investment returns and principal value can fluctuate widely, so an investor’s shares, when sold, could be worth more or less than their original cost.

Though the fund’s ten-year return is clearly unimpressive, keep in mind the time period that it represents. The 500 Index Fund’s performance reflects a decade that included double-digit negative stock market returns in 2001 and 2002 as the late-1990s tech stock bubble deflated and the trauma of the 2008–2009 financial crisis.

The fund’s advisor, Vanguard Quantitative Equity Group, succeeded in tracking its benchmark index—cold comfort, perhaps, but an important measure of the kind of indexing skill that puts you in position to maximize your share of the market’s returns in better times. The advisor is helped in this task by the fund’s low expenses, which are far below the average for its peer group.

Focus on your goals rather than the market’s swings
Over the past few years, investors have been forced to endure an unusually bumpy ride in the U.S. stock market. While these times have, without a doubt, been nerve-racking, they have also been a good reminder that in can be unwise to let market swings influence your long-term investment strategy. Changes have been swift and unpredictable, potentially imposing penalties on investors who use past performance as a guide to the future.

Vanguard encourages you to create a long-term investment plan that includes a mix of stocks, bonds, and short-term investments appropriate for your goals and risk tolerance. Once your plan is in place, it’s important to stick with that plan, regardless of market conditions.

Such a well-balanced portfolio can help cushion some of the market’s volatility while allowing you to participate in its long-term potential for growth. Vanguard 500 Index Fund can play an important role in your long-term investment plan by providing broad, low-cost exposure to the large-cap segment of the stock market.

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 were first issued on September 7, 2010, and first offered to the public on September 9, 2010. 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 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 December 31, 2010, the fund had contributed capital of $16,883,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 6.75% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

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).

The following table summarizes the fund’s investments as of December 31, 2010, based on the inputs used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	102,340,874	—	—
Temporary Cash Investments	373,300	24,985	—
Futures Contracts—Liabilities¹	(283)	—	—
Total	102,713,891	24,985	—
1 Represents variation margin on the last day of the reporting period.

D. At December 31, 2010, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:


				($000)
		Number of	Aggregate	Unrealized
		Long (Short)	Settlement	Appreciation
Futures Contracts	Expiration	Contracts	Value	(Depreciation)
E-mini S&P 500 Index	March 2011	2,000	125,300	770
S&P 500 Index	March 2011	354	110,891	2,220

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 year ended December 31, 2010, the fund realized $967,491,000 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.

For tax purposes, at December 31, 2010, the fund had $8,777,000 of ordinary income available for distribution. 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.

At December 31, 2010, the cost of investment securities for tax purposes was $74,974,401,000.

Net unrealized appreciation of investment securities for tax purposes was $27,764,758,000, consisting of unrealized gains of $37,123,583,000 on securities that had risen in value since their purchase and $9,358,825,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the year ended December 31, 2010, the fund purchased $4,653,528,000 of investment securities and sold $7,170,928,000 of investment securities, other than temporary cash investments.

Report of Independent Registered Public Accounting Firm

To the Trustees of Vanguard Index Funds and the Shareholders of Vanguard 500 Index Fund:

In our opinion, the accompanying statement of net assets and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Vanguard 500 Index Fund (constituting a separate portfolio of Vanguard Index Funds, hereafter referred to as the “Fund”) at December 31, 2010, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management; our responsibility is to express an opinion on these financial statements based on our audits. We co nducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at December 31, 2010 by correspondence with the custodian and broker and by agreement to the underlying ownership records of Vanguard Market Liquidity Fund, provide a reasonable basis for our opinion.

Special 2010 tax information (unaudited) for Vanguard 500 Index Fund

This information for the fiscal year ended December 31, 2010, is included pursuant to provisions of the Internal Revenue Code.

The fund distributed $1,821,281,000 of qualified dividend income to shareholders during the fiscal year.

For corporate shareholders, 100% of investment income (dividend income plus short-term gains, if any) qualifies for the dividends-received deduction.

Your Fund’s After-Tax Returns

This table presents returns for your fund both before and after taxes. The after-tax returns are shown in two ways: (1) assuming that an investor owned the fund during the entire period and paid taxes on the fund’s distributions, and (2) assuming that an investor paid taxes on the fund’s distributions and sold all shares at the end of each period.

Calculations are based on the highest individual federal income tax and capital gains tax rates in effect at the times of the distributions and the hypothetical sales. State and local taxes were not considered. After-tax returns reflect any qualified dividend income . (In the example, returns after the sale of fund shares may be higher than those assuming no sale. This occurs when the sale would have produced a capital loss. The calculation assumes that the investor received a tax deduction for the loss.) The table shows returns for Investor Shares only; returns for other share classes will differ. Please note that your actual after-tax returns will depend on your tax situation and may differ from those shown. Also note that if you own the fund in a tax-deferred account, such as an individual retirement account or a 401(k) plan, this information does not apply to you. Such accounts are not subject to current taxes.

Finally, keep in mind that a fund’s performance—whether before or after taxes—does not guarantee future results.


Average Annual Total Returns: 500 Index Fund Investor Shares
Periods Ended December 31, 2010
	One	Five	Ten
	Year	Years	Years
Returns Before Taxes	14.91%	2.21%	1.31%
Returns After Taxes on Distributions	14.60	1.90	0.97

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 the account service fee described in the prospectus. If such a fee were applied to your account, your costs would be higher. Your fund does not charge transaction fees, such as purchase or redemption fees, nor does it 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 December 31, 2010
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
500 Index Fund	6/30/2010	12/31/2010	Period
Based on Actual Fund Return
Investor Shares	$1,000.00	$1,231.79	$0.96
Admiral Shares	1,000.00	1,232.61	0.28
Signal Shares	1,000.00	1,232.64	0.28
Based on Hypothetical 5% Yearly Return
Investor Shares	$1,000.00	$1,024.35	$0.87
Admiral Shares	1,000.00	1,024.95	0.26
Signal Shares	1,000.00	1,024.95	0.26

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, and 0.05% for Signal 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 table does not include data for share classes of funds with fewer than six months of history.

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 stocks 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 179 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,

Small-capitalization stocks turned in a strong showing for the second consecutive year. The three Vanguard small-cap index funds again closely tracked their respective target indexes; each logged total returns of about 25% or higher for 2010.

Of the three funds, Vanguard Small-Cap Growth Index Fund was the best performer, returning about 31%; Vanguard Small-Cap Value Index Fund, the worst performer, returned “only” about 25% for the year. The broader-based Vanguard Small-Cap Index Fund, which covers both the growth and value segments of the small-cap market, fell in between, with a return of about 28%.

Although outperforming funds that invest in similar stocks is not the objective of these three funds, the Small-Cap and Small-Cap Growth Index Funds did outperform their peer-group averages in 2010. The Small-Cap Value Index Fund trailed its comparable industry average by about one percentage point.

Please note that on October 6, Vanguard broadened the availability of our lower-cost Admiral Shares. We reduced the Admiral minimums on most of our broad-market index funds, including Small-Cap Index Fund, to $10,000 from $100,000, as part of our ongoing efforts to lower the cost of investing for our clients. (Admiral minimums were also lowered for many of our actively managed funds.)

Also, in December we launched Institutional Plus Shares for the Small-Cap Index Fund. These shares require a minimum initial investment of $100 million.

Stocks rallied as the forecast
seemed to brighten
After a series of false starts, hesitations,

and retreats, global stock markets finished 2010 with powerful gains. As the prospect of a double-dip recession faded, the broad U.S. stock market clambered higher, shrugging off high unemployment and distress in Europe’s debt markets to return 17.70%. Small- and mid-capitalization stocks did even better.

Outside the United States, gains were more muted, in part because Europe’s sovereign debt challenges continued to reverberate through local stock markets. Emerging markets were the best performers. Asia’s developed markets performed poorly, though the strength of the yen, the Australian dollar, and other regional currencies bolstered returns for U.S.-based investors.

The fixed income market
reprised a familiar theme
Although U.S. Treasury securities rallied

through the summer, total return tables were dominated by riskier bonds for the full 12 months, a pattern we also saw in 2009. Low interest rates and a sense that the economic recovery was gathering

momentum prompted investors to seek higher yields in both high-quality and below-investment-grade corporate bonds. The broad U.S. bond market returned 6.54%. Late in the year, yields bounced off summer lows, putting pressure on bond prices. The dynamic was especially pronounced among municipal bonds.

As it has since December 2008, the Federal Reserve held its target for short-term interest rates near 0%, keeping the returns available from money market instruments such as the 3-month Treasury bill in the same neighborhood.

IT stocks again led small-caps to strong gains
As the economic recovery gained some modest momentum, smaller-company stocks continued to outperform larger companies in 2010, just as they did in 2009. And once again, every sector across the small-cap arena registered gains.

Small-cap information technology companies represented the largest contributor to Small-Cap Index Fund’s advance as consumers and businesses stepped up computer-related purchases and investors remained optimistic about continued growth in the sector. IT stocks also did the best of any sector in Small-Cap Growth Index Fund. Software firms, which comprise one of the largest IT subsectors, were the best performers.

For the fiscal year ended December 31, 2010, the funds’ expense ratios were: for the Small-Cap Index Fund, 0.26% for Investor Shares, 0.12% for Admiral Shares, 0.12% for Signal Shares, 0.08% for Institutional Shares, and 0.12% for ETF Shares; for the Small-Cap Growth Index Fund, 0.26% for Investor Shares, 0.08% for Institutional Shares, and 0.12% for ETF Shares; and for the Small-Cap Value Index Fund, 0.26% for Investor Shares, 0.08% for Institutional Shares, and 0.12% for ETF Shares. For the fiscal period ended December 31, 2010, the annualized expense ratio for the Small-Cap Index Fund Institutional Plus Shares was 0.06%.

Unsurprisingly, given that the economy is recovering from a recession, traditionally cyclical sectors such as industrials did well, with manufacturing, transportation, and shipping companies advancing. Another cyclical bellwether, the consumer discretionary sector, also advanced sharply as consumers felt more confident in opening their wallets.

Financial firms, the largest small-cap sector, posted healthy gains, although they were not as robust as those made in the aforementioned industries. Real estate investment trusts, insurance companies, banks, and the like continued to make progress in repairing their balance sheets.

Energy, a relatively small sector in the small-cap arena, showed the sharpest rise. Increasing demand and prices powered energy-related stocks to gains that, in all three funds, exceeded 35%.

A look at a decade of returns provides an important perspective
While the investment community tends to focus on short-term performance, we’ve always believed the long-term view is far more important. Looking at returns over longer periods can filter out short-term market trends, giving a truer picture of a fund’s performance.

For the decade ended December 31, 2010, each of the funds captured the performance of its respective benchmark, producing a solid single-digit return.

The funds’ longer-term track records are a credit to the funds’ advisor, Vanguard Quantitative Equity Group, and its team of experienced professionals. The group relies on its time-tested portfolio management strategies to help keep the funds closely aligned with their benchmarks in both up and down markets. As a result, the three funds have successfully tracked the returns from the small-cap market, whether those returns are for the entire small-cap segment or for a subset of it.

When measured against industry averages for small-cap funds, two of the three funds have outperformed for the ten years.

Small-Cap Value Index Fund’s 10-year figure trails that of the industry by about half a percentage point.

It’s worth noting that for the ten-year period all three funds far outperformed the broad U.S. stock market (as measured by the Dow Jones U.S. Total Stock Market Index), which posted average annual returns of less than 3%. Compared with mid- and large-cap stocks, small-cap stocks have been relatively stellar performers over the past 10 years. Given the fact that larger-company stocks have often outperformed small-caps during different periods, small-cap investors would be wise not to count on a repeat performance over the next decade. No one knows whether it will be large-cap stocks’ turn to take the lead in the years ahead, but we encourage our clients to maintain reasonable expectations, especially after a particular investment category has outperformed.

Our small-cap funds can serve as a useful building block
Although the past year did not experience the severe swings of 2008 or 2009, periods of instability still buffeted investors as the global marketplace continued to reverberate with aftershocks from the financial crisis. During times of volatility, it helps to remember that adopting a long-term perspective and maintaining a diversified portfolio can help make month-to-month price swings seem less threatening.

In practice, this means building a cost-efficient portfolio that includes a steady mix of stocks, bonds, and short-term reserves, one that can provide some protection against market losses while allowing you to participate in the long-term potential for accumulating returns in each asset class. So while our small-cap index funds offer a convenient way to seek to capture the returns across this sometimes-volatile market segment, we consider the funds best suited to be part of a broad-based, diversified investment program.

Thank you for investing with Vanguard.

Sincerely,

F. William McNabb III
Chairman and Chief Executive Officer

Small-Cap Index Fund

Notes to Financial Statements

Vanguard Small-Cap Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. 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. Institutional Plus Shares were first issued on December 17, 2010. 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

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 December 31, 2010, the fund had contributed capital of $3,862,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 1.54% 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 December 31, 2010, based on the inputs
used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	23,968,134	—	—
Temporary Cash Investments	477,032	9,597	—

Futures Contracts—Liabilities¹	(570)	—	—
Total	24,444,734	9,597	—
1 Represents variation margin on the last day of the reporting period.

Small-Cap Index Fund

D. At December 31, 2010, 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	March 2011	696	54,448	(444)

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 are primarily attributed to tax deferral of losses on wash sales and 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 year ended December 31, 2010, the fund realized $1,388,743 ,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.

For tax purposes, at December 31, 2010, the fund had $332,000 of ordinary income available for distribution. 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.

At December 31, 2010, the cost of investment securities for tax purposes was $20,281,503,000. Net unrealized appreciation of investment securities for tax purposes was $4,173,260,000, consisting of unrealized gains of $5,615,865,000 on securities that had risen in value since their purchase and $1,442,605,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the year ended December 31, 2010, the fund purchased $7,298,774,000 of investment securities and sold $5,183,605,000 of investment securities, other than temporary cash investments.

Small-Cap Growth Index Fund

Notes to Financial Statements

Vanguard Small-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 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 December 31, 2010, the fund had contributed capital of $1,185,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 0.47% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

D. At December 31, 2010, 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	March 2011	505	39,506	192

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 are primarily attributed to tax deferral of losses on wash sales and 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 year ended December 31, 2010, the fund realized $424,274,000 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.

For tax purposes, at December 31, 2010, the fund had $62,000 of ordinary income available for distribution. 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.

At December 31, 2010, the cost of investment securities for tax purposes was $6,019,301,000. Net unrealized appreciation of investment securities for tax purposes was $1,758,776,000, consisting of unrealized gains of $1,966,364,000 on securities that had risen in value since their purchase and $207,588,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the year ended December 31, 2010, the fund purchased $3,867,886,000 of investment securities and sold $3,046,573,000 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 December 31, 2010, the fund had contributed capital of $1,155,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 0.46% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

D. At December 31, 2010, 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	March 2011	132	10,326	(37)

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

During the year ended December 31, 2010, the fund realized $349,443,000 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.

For tax purposes, at December 31, 2010, the fund had $317,000 of ordinary income available for distribution. 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.

At December 31, 2010, the cost of investment securities for tax purposes was $5,915,195,000. Net unrealized appreciation of investment securities for tax purposes was $1,170,479,000, consisting of unrealized gains of $1,415,456,000 on securities that had risen in value since their purchase and $244,977,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the year ended December 31, 2010, the fund purchased $3,219,592,000 of investment securities and sold $2,509,345,000 of investment securities, other than temporary cash investments.

Report of Independent Registered Public Accounting Firm

To the Trustees of Vanguard Index Funds and the Shareholders of Vanguard Small-Cap Index Fund, Vanguard Small-Cap Growth Index Fund and Vanguard Small-Cap Value Index Fund: In our opinion, the accompanying statements of net assets-investments summary and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Vanguard Small-Cap Index Fund, Vanguard Small-Cap Growth Index Fund and Vanguard Small-Cap Value Index Fund (constituting separate portfolios of Vanguard Index Funds, hereafter referred to as the “Funds”) at December 31, 2010, the results of each of their operations for the year then ended, the changes in each of their net assets for each of the two years in the period then ended and the financial highlights for each of the periods indicated, in conformity with accounting principles generally accepted i n the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Funds’ management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at December 31, 2010 by correspondence with the custodian and broker and by agreement to the underlying ownership records of Vanguard Market Liquidity Fund, provide a reasonable basis for our opinion.

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, 0.26% for Investor Shares, 0.12% for Admiral Shares, 0.12% for Signal Shares, 0.08% for Institutional Shares, and 0.12% for ETF Shares; for the Small-Cap Growth Index Fund, 0.26% for Investor Shares, 0.08% for Institutional Shares, and 0.12% for ETF Shares; and for the Small-Cap Value Index Fund, 0.26% for Investor Shares, 0.08% for Institutional Shares, and 0.12% 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 f unds with fewer than six months of history.

Chairman’s Letter

Dear Shareholder,

The first half of 2010 was marked by uncertainty about the strength of the global economic recovery and about the sovereign debt crisis in Europe. As evidence of a solid economic rebound mounted, and as plans to aid struggling countries in Europe materialized, the market posted robust gains in the second half of the year. The returns of small- and mid-sized stocks were especially strong.

For the full year, the returns of the four Vanguard Mid-Capitalization Index Funds in this report ranged from almost 22% for Vanguard Mid-Cap Value Index Fund to about 29% for Vanguard Mid-Cap Growth Index Fund. That performance reflected the strength of mid-cap stocks during the year. Vanguard Extended Market Index Fund, which invests in both small- and mid-cap stocks, turned in the second-best performance. The fund’s exposure to high-flying small-caps kept it a few steps ahead of Vanguard Mid-Cap Index Fund. All four funds closely tracked their benchmark indexes.

Index strategies can be a tax-efficient approach to investing in mid-cap stocks. If you own shares of the fund in a taxable account, you may wish to review the fund’s after-tax returns, which appear later in this report.

Please note that on October 6, Vanguard broadened the availability of our lower-cost Admiral Shares. We reduced the minimum investment requirement for these shares to $10,000 in most of our broad-market index funds, down from $100,000. In addition, in December we announced the addition of Institutional Plus Shares for several funds, including the Extended Market Index Fund and the Mid-Cap Index Fund. (The Extended Market Index Fund’s new shares were launched in January, shortly after the close of the reporting period.) The changes are part of our ongoing efforts to lower the cost of investing for our clients.

Outside the United States, gains were more muted, in part because Europe’s sovereign debt challenges continued to reverberate through local stock markets. Emerging markets were the best

performers. Asia’s developed markets performed weakly, though the strength of the yen, the Australian dollar, and other regional currencies bolstered returns for U.S.-based investors.

As it has since December 2008, the Fed held its target for short-term interest rates near 0%, keeping the returns available from money market instruments such as the 3-month Treasury bill in the same neighborhood.

Most market sectors displayed signs of strength during the year
Throughout the first half of the year, stocks across all market capitalizations were on a roller-coaster ride as worries about economic growth and the debt issues plaguing nations in Europe grabbed headlines. But as concerns on both fronts receded, markets rebounded in the second half, with mid-cap and small-cap stocks outperforming their large-cap brethren, a familiar pattern in the early stages of an economic recovery. The rally was broad-based, with all ten stock market sectors in the four funds posting gains for the year.

Consumer discretionary stocks were a big driver of performance, gaining about 30% or more for the year in all four funds. With consumer spending showing signs of improvement, hotels, restaurants, and leisure stocks, as well as specialty retailers, posted major gains. At the

same time, the economic recovery and a rebound in advertising helped power strong performance by media stocks. The consumer discretionary sector was the biggest contributor to performance in all but the Mid-Cap Value Index Fund, which has less exposure to the sector than the three other funds. Even so, these stocks were the second-biggest contributor to that fund’s performance for the year.

Financial stocks also posted strong gains in all four funds. Real estate investment trusts were strong performers. Over the past few years, the real estate meltdown forced many REITs to shore up their balance sheets, which put them in a strong position as the economy started to pick up and the outlook for rents and vacancy rates improved. Commercial banks posted healthy returns as credit quality began to improve. The strength of financial stocks was a key driver of the performance of the Mid-Cap Value Index Fund in particular. The sector was the fund’s single biggest concentration, accounting for about 30% of portfolio assets, on average.

Although technology stocks produced ordinary returns in the Mid-Cap Value Fund, the sector was a strength in the Mid-Cap Growth and Extended Market Index Funds. Software stocks posted gains as corporate IT spending, which was slashed during the recession, made a comeback. The Mid-Cap Value Index Fund has less exposure to software, as its index places greater emphasis on semiconductor and hardware stocks, which were some of the sector’s weaker performers.

Industrial stocks performed well in all four funds, particularly in the Mid-Cap Growth and the Extended Market Index Funds. Shares of companies that make and sell construction and farm machinery and heavy trucks saw outsized returns, a consequence, perhaps, of the global boom in prices for farm products.

A decade of small but important triumphs
The funds’ long-term returns have been solid, if somewhat below historical stock market averages, a reflection of the decade’s tough investment environment. The four funds have nevertheless done an excellent job of tracking the performance of their target indexes, the primary goal for any index fund.

The two funds that have been in existence for more than ten years—the Extended Market Index Fund and the Mid-Cap Index Fund—have captured most of the returns of their target indexes, trailing by small amounts consistent with the costs of managing real-world portfolios. The Mid-Cap Growth and Value Index Funds, which made their debuts in August 2006, have also succeeded in tracking the returns of their benchmarks.

The records are a testament to the funds’ advisor, Vanguard Quantitative Equity Group, which has been managing index portfolios for more than 30 years. This group of experienced professionals uses well-honed portfolio construction and trading methodologies that allow Vanguard to provide effective index tracking and fund

management regardless of the market’s volatility or direction. That approach also benefits, of course, from the funds’ low operating expenses.

The two older funds have outperformed their peer groups over the past decade, while the two newer funds have returned a bit less than theirs since their 2006 inceptions. Over time, we would expect Vanguard’s low-cost indexing strategies to provide competitive returns relative to their peer groups, which consist largely of higher-cost, actively managed funds.

Diversifying: An effective response to uncertainty in investing
The ups and downs of the past year, not to mention the steep and painful declines of the recent past, have tested investors in fundamental ways. Although many economic signs point toward a positive investing environment over the next year, it is impossible to predict when the next crisis may erupt or whether the gains of late 2010 will continue.

In the face of such uncertainty, it is more important than ever to follow a disciplined, time-tested approach to investing. That’s why Vanguard has always advocated that investors hold a diversified portfolio that includes stock, bond, and money market funds in a weighting that matches their risk tolerance and time horizon. Vanguard’s mid-cap index funds can be a valuable component of such a balanced investment portfolio.

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

Sincerely,

F. William McNabb III

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

S&P MidCap 400 Index	March 2011	36	16,295	241

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

During the year ended December 31, 2010, the fund realized $628,567,000 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.

For tax purposes, at December 31, 2010, the fund had $4,094,000 of ordinary income available for distribution. 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.

Extended Market Index Fund

At December 31, 2010, the cost of investment securities for tax purposes was $14,433,519,000. Net unrealized appreciation of investment securities for tax purposes was $3,187,892,000, consisting of unrealized gains of $4,585,007,000 on securities that had risen in value since their purchase and $1,397,115,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the year ended December 31, 2010, the fund purchased $3,838,085,000 of investment securities and sold $2,384,996,000 of investment securities, other than temporary cash investments.

Mid-Cap Index Fund

Notes to Financial Statements

Vanguard Mid-Cap Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. 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. Institutional Plus Shares were first issued on December 15, 2010. 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.

Mid-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 December 31, 2010, the fund had contributed capital of $4,278,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 1.71% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

The following table summarizes the fund’s investments as of December 31, 2010, based on the inputs used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	26,069,369	—	—
Temporary Cash Investments	154,634	400	—
Futures Contracts—Liabilities¹	(22)	—	—
Total	26,223,981	400	—
1 Represents variation margin on the last day of the reporting period.

Mid-Cap Index Fund

D. At December 31, 2010, 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 MidCap 400 Index	March 2011	7	3,169	49

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 are primarily attributed to tax deferral of losses on wash sales and 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 year ended December 31, 2010, the fund realized $1,085,523,000 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.

For tax purposes, at December 31, 2010, the fund had $2,352,000 of ordinary income available for distribution. 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.

At December 31, 2010, the cost of investment securities for tax purposes was $21,268,220,000. Net unrealized appreciation of investment securities for tax purposes was $4,956,183,000, consisting of unrealized gains of $6,201,277,000 on securities that had risen in value since their purchase and $1,245,094,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the year ended December 31, 2010, the fund purchased $7,670,344,000 of investment securities and sold $5,913,593,000 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 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 December 31, 2010, the fund had contributed capital of $305,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 0.12% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

At December 31, 2010, 100% of the fund’s investments were valued based on Level 1 inputs.

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 are primarily attributed to tax deferral of losses on wash sales and 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 year ended December 31, 2010, the fund realized $113,188,000 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.

For tax purposes, at December 31, 2010, the fund had $179,000 of ordinary income available for distribution. 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 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.

Mid-Cap Growth Index Fund

At December 31, 2010, the cost of investment securities for tax purposes was $1,602,914,000. Net unrealized appreciation of investment securities for tax purposes was $398,900,000, consisting of unrealized gains of $431,299,000 on securities that had risen in value since their purchase and $32,399,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended December 31, 2010, the fund purchased $1,329,254,000 of investment securities and sold $914,802,000 of investment securities, other than temporary cash investments.

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

Mid-Cap Value Index Fund

Notes to Financial Statements

Vanguard Mid-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 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.

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

Mid-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 December 31, 2010, the fund had contributed capital of $232,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 0.09% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

Common Stocks	1,429,391	—	—
Temporary Cash Investments	3,631	100	—
Total	1,433,022	100	—

During the year ended December 31, 2010, the fund realized $97,850,000 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.

Mid-Cap Value Index Fund

For tax purposes, at December 31, 2010, the fund had $166,000 of ordinary income available for distribution. 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.

At December 31, 2010, the cost of investment securities for tax purposes was $1,204,383,000. Net unrealized appreciation of investment securities for tax purposes was $228,739,000, consisting of unrealized gains of $252,962,000 on securities that had risen in value since their purchase and $24,223,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended December 31, 2010, the fund purchased $971,732,000 of investment securities and sold $803,302,000 of investment securities, other than temporary cash investments.

In our opinion, the accompanying statement of net assets—investments summary and statements of net assets and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Vanguard Extended Market Index Fund, Vanguard Mid-Cap Index Fund, Vanguard Mid-Cap Growth Index Fund and Vanguard Mid-Cap Value Index Fund (constituting separate portfolios of Vanguard Index Funds, hereafter referred to as the “Funds”) at December 31, 2010, the results of each of their operations for the year then ended, the changes in each of their net assets for each of the two years in the period then ended and the financial highlights for each of the periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Funds’ management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at December 31, 2010 by correspondence with the custodian and broker and by agreement to the underlying ownership records of Vanguard Market Liquidity Fund, provide a reasonable bas is for our opinion.

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, 0.26% for Investor Shares, 0.12% for Admiral Shares, 0.12% for Signal Shares, 0.08% for Institutional Shares, and 0.12% for ETF Shares; for the Mid-Cap Index Fund, 0.26% for Investor Shares, 0.12% for Admiral Shares, 0.12% for Signal Shares, 0.08% for Institutional Shares, and 0.12% for ETF Shares; for the Mid-Cap Growth Index Fund, 0.26% for Investor Shares and 0.12% for ETF Shares; and for the Mid-Cap Value Index Fund, 0.26% for Investor Shares and 0.12% 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.

Chairman’s Letter

Dear Shareholder,

The first half of 2010 was marked by uncertainty about the strength of the global economic recovery and the sovereign debt crisis in Europe. As evidence of a solid economic rebound mounted, and as plans to aid struggling countries in Europe materialized, the market posted sizable gains in the second half of the year.

With global economies reviving, growth stocks outperformed value stocks for the 12 months. Vanguard Growth Index Fund returned about 17%, the Value Index Fund returned about 14%, and the Large-Cap Index Fund, which blends the two styles, fell in between. All three funds closely tracked their target indexes for the 12-month period, and all outpaced the average returns of their peer groups. (Vanguard Total Stock Market Index Fund, which was previously included in this report, now has its own report.)

Large-cap indexing strategies have the potential to be relatively tax-efficient. Despite their strong total returns, none of the Vanguard Large-Cap Index Funds distributed a capital gain in 2010. If you hold any of these funds in a taxable account, you may wish to review the after-tax returns that appear later in this report.

Please note that on October 6, Vanguard broadened the availability of our lower-cost Admiral Shares. We reduced the minimum investment requirement for these shares to $10,000 in most of our broad-market index funds, down from $100,000. The change is part of our ongoing efforts to lower the cost of investing for our clients.

higher yields in both high-quality and below-investment-grade corporate bonds. The broad U.S. bond market returned 6.54%. Late in the year, yields bounced off summer lows, putting pressure on bond prices. The dynamic was especially pronounced among municipal bonds.

As it has since December 2008, the Fed held its target for short-term interest rates near 0%, keeping the returns available from money market instruments, such as the 3-month Treasury bill, in the same neighborhood.

The large-cap funds rallied with the markets’ return to health
Despite ongoing challenges, such as high unemployment and a weak housing market, the three Vanguard large-cap index funds posted double-digit returns, thanks in large part to the broad market rally in the second half of 2010.

Although the funds didn’t reproduce the outsized gains earned in 2009, performance was solid across the board, with strength in just about every sector. The funds recorded their big gains in consumer discretionary and industrial stocks, both of which are sensitive to turns in the business cycle.

The fund expense ratios shown are from the prospectus dated April 29, 2010, and represent estimated costs for the current fiscal year. For the fiscal year ended December 31, 2010, the funds’ expense ratios were: for the Growth Index Fund, 0.26% for Investor Shares, 0.12% for Admiral Shares, 0.12% for Signal Shares, 0.08% for Institutional Shares, and 0.12% for ETF Shares; for the Value Index Fund, 0.26% for Investor Shares, 0.12% for Admiral Shares, 0.12% for Signal Shares, 0.08% for Institutional Shares, and 0.12% for ETF Shares; and for the Large-Cap Index Fund, 0.26% for Investor Shares, 0.12% for Admiral Shares, 0.12% for Signal Shares, 0.08% for Institutional Shares, and 0.12% for ETF Shares. The peer-group expense ratios are derived from data provided by Lipper Inc. and capture information through year-end 2009.

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

Consumer discretionary stocks contributed almost a quarter of the overall return of the Growth Index Fund—more than any other sector. The sector also made sizable, if somewhat smaller, contributions to the Large-Cap and Value Index Funds. The economic recovery and a rebound in advertising helped power strong performance by media stocks. With consumer spending showing signs of improvement, restaurants and hotels, resorts, and cruise lines also posted major gains.

Industrial stocks were a significant contributor to returns, posting a gain of 20% or more in each fund. Machinery stocks, which were hit hard in the recession, continued to benefit from the ongoing U.S. recovery. Shares of

companies that make and sell construction and farm machinery and heavy trucks produced outsized returns amid a boom in prices for agricultural products.

Financial stocks registered solid gains as banks, brokerages, and insurance companies continued to put some distance between the financial crisis and their financial statements. Insurance stocks, in particular, saw healthy returns. And despite a high number of bank failures during the year, commercial banks overall produced good returns as credit quality for most of the group continued to show gradual improvement. These stocks account for about one-fourth of the Value Index Fund’s assets; they have more modest allocations in the two other funds.

Recent market traumas haunt the funds’ long-term returns
Although the past year’s gains have been encouraging, we advise investors to beware of focusing too closely on short-term returns. Instead, we counsel our shareholders to adopt a longer-term perspective, which can provide a better sense of how an investment performs over time and through a variety of market environments.

Even with that patient perspective, however, there is no escaping the impact of the stunning market decline two years ago, the worst since the 1930s. As a result of that collapse, the Large-Cap Index Fund has posted a modest 4.09% average annual return since its inception in early 2004. For the Growth and Value Index Funds, which have existed longer, the record is further affected by the market plunge that followed the bursting of the tech-stock bubble in 2000. Over the past ten years, each has produced average annual returns of less than 2%. Although these numbers seem paltry, the returns of all three large-cap index funds were superior to the average returns of their peer groups.

Certainly investors have had to weather some unsettling market gyrations over the last several years. But Vanguard’s large-cap index funds have delivered on their primary objective of matching the performance of their respective benchmarks. That performance is a testament to the funds’ advisor, Vanguard Quantitative Equity Group, which has been developing its indexing expertise for more than 30 years. This group of experienced professionals uses well-honed portfolio construction and

trading methodologies that allow Vanguard to provide effective index-tracking fund management regardless of the market’s volatility or direction. That approach also benefits, of course, from the funds’ low operating expenses.

Diversifying: An effective response to uncertainty in investing
The ups and downs of the past year, not to mention the steep and painful declines of the recent past, have tested investors in very fundamental ways. Although many economic signs point toward a positive investing environment over the next year, it is impossible to predict when the next crisis may erupt or whether the gains of late 2010 will continue.

In the face of such uncertainty, it is more important than ever to follow a disciplined, time-tested approach to investing. That’s why Vanguard has always advocated that investors hold a diversified portfolio that includes stock, bond, and money market funds in weightings that match their risk tolerance and time horizon. Vanguard’s large-cap index funds can be a valuable component of that balanced investment portfolio.

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

Sincerely,

F. William McNabb III
Chairman and Chief Executive Officer

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 December 31, 2010, the fund had contributed capital of $3,187,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 1.27% 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).

At December 31, 2010, 100% of the fund’s investments were valued based on Level 1 inputs.

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 year ended December 31, 2010, the fund realized $37,719,000 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.

For tax purposes, at December 31, 2010, the fund had $1,092,000 of ordinary income available for distribution. The fund had available capital loss carryforwards totaling $1,739,149,000 to offset future net capital gains of $742,396,000 through December 31, 2011, and $996,753,000 through December 31, 2017. Capital loss carryforwards of $251,682,000 expired on December 31, 2010; accordingly, such losses have been reclassified from accumulated net realized losses to paid-in capital.

At December 31, 2010, the cost of investment securities for tax purposes was $15,096,347,000. Net unrealized appreciation of investment securities for tax purposes was $4,196,113,000, consisting of unrealized gains of $4,597,651,000 on securities that had risen in value since their purchase and $401,538,000 in unrealized losses on securities that had fallen in value since their purchase.

Growth Index Fund

E. During the year ended December 31, 2010, the fund purchased $5,431,557,000 of investment securities and sold $4,398,831,000 of investment securities, other than temporary cash investments.

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

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 December 31, 2010, the fund had contributed capital of $2,305,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 0.92% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

At December 31, 2010, 100% of the fund’s investments were valued based on Level 1 inputs.

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 year ended December 31, 2010, the fund realized $16,227,000 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.

For tax purposes, at December 31, 2010, the fund had $1,936,000 of ordinary income available for distribution. 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.

At December 31, 2010, the cost of investment securities for tax purposes was $13,579,604,000. Net unrealized appreciation of investment securities for tax purposes was $656,863,000, consisting of unrealized gains of $1,742,031,000 on securities that had risen in value since their purchase and $1,085,168,000 in unrealized losses on securities that had fallen in value since their purchase.

E. During the year ended December 31, 2010, the fund purchased $4,473,890,000 of investment securities and sold $3,363,075,000 of investment securities, other than temporary cash investments.

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 December 31, 2010, the fund had contributed capital of $739,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 0.30% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

The following table summarizes the fund’s investments as of December 31, 2010, based on the inputs used to value them:


	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	4,513,429	—	—
Temporary Cash Investments	16,131	750	—
Futures Contracts—Liabilities¹	(8)	—	—
Total	4,529,552	750	—
1 Represents variation margin on the last day of the reporting period.

D. At December 31, 2010, 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	March 2011	20	6,265	110

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

During the year ended December 31, 2010, the fund realized $33,838,000 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.

For tax purposes, at December 31, 2010, the fund had $394,000 of ordinary income available for distribution. 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.

At December 31, 2010, the cost of investment securities for tax purposes was $4,064,071,000. Net unrealized appreciation of investment securities for tax purposes was $466,239,000, consisting of unrealized gains of $728,337,000 on securities that had risen in value since their purchase and $262,098,000 in unrealized losses on securities that had fallen in value since their purchase.

Large-Cap Index Fund

F. During the year ended December 31, 2010, the fund purchased $582,562,000 of investment securities and sold $410,919,000 of investment securities, other than temporary cash investments.

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

Report of Independent Registered Public Accounting Firm

To the Trustees of Vanguard Index Funds and the Shareholders of Vanguard Growth Index Fund, Vanguard Value Index Fund and Vanguard Large-Cap Index Fund:

In our opinion, the accompanying statements of net assets and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Vanguard Growth Index Fund, Vanguard Value Index Fund and Vanguard Large-Cap Index Fund (constituting separate portfolios of Vanguard Index Funds, hereafter referred to as the “Funds”) at December 31, 2010, the results of each of their operations for the year then ended, the changes in each of their net assets for each of the two years in the period then ended and the financial highlights for each of the periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Funds’ management; our responsibil ity is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at December 31, 2010 by correspondence with the custodian and broker and by agreement to the underlying ownership records of Vanguard Market Liquidity Fund, provide a reasonable basis for our opinion.

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.

Chairman’s Letter

Dear Shareholder,

Vanguard Total Stock Market Index Fund, which holds a blend of growth and value stocks of all market capitalizations, closely tracked the performance of its benchmark, the MSCI US Broad Market Index, which posted a 17.28% gain for the year. The average return of the fund’s peer group was 15.55%.

A broad market index fund can be a tax-efficient stock market investment. Despite its strong return, Vanguard Total Stock Market Index Fund distributed no capital gains in 2010. If you hold the fund in a taxable account, you may wish to review the after-tax returns that appear later in this report.

Please note that on October 6, Vanguard broadened the availability of our lower-cost Admiral Shares. We reduced the minimum investment requirement for these shares to $10,000 in most of our broad-market index funds, down from $100,000. The change is part of our ongoing efforts to lower the cost of investing for our clients.

Stocks rallied as the forecast seemed to brighten
After a series of false starts, hesitations, and retreats, global stock markets finished 2010 with powerful gains. As the prospect of a double-dip recession faded, the broad U.S. stock market clambered higher, shrugging off high unemployment and distress in Europe’s debt markets to return more than 17%. Small- and mid-capitalization stocks did even better.

Most market sectors displayed signs of strength during the year
Vanguard Total Stock Market Index Fund, designed to track the performance of the broad U.S. market, was bolstered by an apparent acceleration of the U.S. economic recovery. As fears faded that the U.S. would slip back into recession, and as the prospects for an uptick in consumer spending and in business investment brightened, the market enjoyed a strong rally.

Gains were broad-based, with all but the health care and utilities sectors posting double-digit returns. Consumer discretionary and industrial stocks turned in the best performances.

Consumer discretionary stocks gained more than 30% for the period. The economic recovery and a rebound in advertising helped power strong performance by media stocks. And with consumer spending showing signs of improvement, restaurants and hotels, resorts, and cruise lines posted major gains.

Peer group: Multi-Cap Core Funds.

Stocks in the industrial sector were close behind, returning 27%. Machinery stocks, which were hit hard in the recession, continued to benefit from the ongoing U.S. recovery. Shares of companies that make and sell construction and farm machinery and heavy trucks saw outsized returns, a consequence, perhaps, of the global boom in prices of agricultural products. Energy and materials stocks, two sectors with an industrial flavor, also delivered impressive gains.

Financial stocks rose as banks, brokerages, and insurance companies continued to put some distance between the financial crisis and their financial statements. Insurance stocks, in particular, saw healthy returns. And despite a high number of bank failures during the year, commercial banks overall posted good returns as credit quality for most of the group continued to show gradual improvement.

The utilities and health care sectors produced more pedestrian returns. A variety of company-specific concerns weighed on the big pharmaceutical companies and medical-equipment makers, while the sluggish economic expansion left power producers with idle capacity.

Over the last ten years the Total Stock Market Index Fund’s Investor Shares have produced an average annual return of 2.45%. That is in line with the benchmark return over the period and nearly one

percentage point higher than the average for its peer group of funds, many of which are actively managed.

Tight index tracking is the definition of success for an index fund manager. The goal is simple, but the task can be challenging, especially during episodes of extreme volatility, such as the bursting of the tech stock bubble early in the decade and the global financial crisis near the end. The fund’s success in tracking its index is a testament to the expertise of the fund’s advisor, Vanguard Quantitative Equity Group. Drawing on more than 30 years of experience, this group of professionals uses well-honed portfolio construction and trading methodologies that have allowed Vanguard to provide effective index-tracking fund management regardless of the market’s volatility or direction. The fund has also benefited from its low costs, which close the gap between index results and your results.

A tough decade demands perspective from investors
Although investors may be less than enthusiastic about the returns of the Total Stock Market Index Fund and other equity funds over the last ten years, it is critical to put those returns in perspective. This decade was among the worst in U.S. stock market history. Investors who are willing to weather these sometimes long-lasting storms can keep themselves in position to earn better returns when the stock market recovers, as it has over the past two years.

A key to waiting out the storm is to resist impulses such as the often counterproductive urge to flee when markets turn rough. Balance and diversification, which can blunt the impact of downturns, are useful allies in this struggle. That is why Vanguard counsels investors to build a diversified portfolio of stock, bond, and money market investments tailored to their risk tolerance and time horizon in order to be best positioned to prosper, regardless of the market’s short-term gyrations. Vanguard Total Stock Market Index Fund, with its broad mandate and low cost, can be a useful core element in such a portfolio.

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

Sincerely,

F. William McNabb III

Total Stock Market Index Fund

Notes to Financial Statements

Vanguard Total Stock Market 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.

Total Stock Market 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 December 31, 2010, the fund had contributed capital of $25,640,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 10.25% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

D. At December 31, 2010, 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

S&P MidCap 400 Index	March 2011	56	25,348	334

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

During the year ended December 31, 2010, the fund realized $3,256,405,000 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.

In December 2007, the fund issued 17,301,549 capital shares for a value of $583,408,000 in connection with a nontaxable in-kind transfer of investment securities from a common trust fund. The securities received in the transfer had net unrealized appreciation, creating a difference between the cost of investments for financial statement and tax purposes that reverses when the securities are sold; $59,748,000 of this difference remained at December 31, 2009. Through December 31, 2010, the remaining securities were sold; as a result the remaining difference between financial statement and tax-basis realized and unrealized gains and losses reversed during the current period.

Total Stock Market Index Fund

For tax purposes, at December 31, 2010, the fund had $34,151,000 of ordinary income available for distribution. 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.

At December 31, 2010, the cost of investment securities for tax purposes was $135,501,129,000. Net unrealized appreciation of investment securities for tax purposes was $15,554,230,000, consisting of unrealized gains of $29,058,771,000 on securities that had risen in value since their purchase and $13,504,541,000 in unrealized losses on securities that had fallen in value since their purchase.

F. During the year ended December 31, 2010, the fund purchased $22,022,781,000 of investment securities and sold $12,021,550,000 of investment securities, other than temporary cash investments.

Report of Independent Registered Public Accounting Firm

To the Trustees of Vanguard Index Funds and the Shareholders of Vanguard Total Stock Market Index Fund:

In our opinion, the statement of net assets–investments summary and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Vanguard Total Stock Market Index Fund (constituting a separate portfolio of Vanguard Index Funds, hereafter referred to as the “Fund”) at December 31, 2010, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at December 31, 2010 by correspondence with the custodian and broker and by agreement to the underlying ownership records of Vanguard Market Liquidity Fund, provide a reasonable basis for our opinion.
