President’s Letter

Dear Shareholder,

During what was an extremely difficult six months for the U.S. stock market, Vanguard Growth and Income Fund returned about –33%. The fund under-performed its benchmark, the Standard & Poor’s 500 Index, as well as the average return of large-cap core funds.

Throughout the period, the ongoing recession affected all corners of the market, and the Growth and Income Fund, like the market, posted negative results in all ten industry sectors. The fund’s biggest losses stemmed from financials and industrials, two of the stock market’s weakest performers during the six months.

Extreme distress dappled with glimmers of hope

The six months ended March 31 witnessed extreme distress in global stock markets, with both U.S. and international stocks returning about –31%. The embattled financial sector continued to struggle, prompting regulators in the United States and abroad to take ever-more-aggressive actions to help the big banks fortify their fragile balance sheets.

Even as the gloom intensified, a few signs of recovery appeared on the horizon. Toward the end of the period, the swift contraction in manufacturing activity seemed to lessen. And throughout the six months, news from the housing sector seemed to improve. From their early March lows through the end of the period, global stock markets generated a double-digit return.

Credit-market turmoil provoked dramatic response

Developments in the fixed income market were, if anything, even more unusual. In the months after the September collapse of Lehman Brothers, a major presence in the bond market, the trading of corporate bonds came to a near standstill as investors stampeded into U.S. Treasury bonds—considered the safest, most liquid credits—driving prices higher and yields lower. The difference between the yields of Treasuries and corporate bonds surged to levels not seen since the 1930s.

The Fed also created new programs designed to bring borrowers and lenders back to the market. For the six-month period, the Barclays Capital U.S. Aggregate Bond Index returned 4.70% on the strength of Treasuries and other government-backed bonds. The broad municipal bond market returned 5.00%.

Losses in all sectors hindered fund performance

The primary objective of Growth and Income Fund’s advisor, Mellon Capital Management (formerly known as Franklin Portfolio Associates, LLC), is to outpace the returns of the fund’s benchmark, the S&P 500 Index. In an effort to do so, the advisor relies on stock-selection models to overweight and underweight individual stocks relative to the index, while closely

mirroring the index’s sector weightings. For the six-month period, the fund managers followed these models but fell short of the ultimate goal of surpassing the benchmark’s return.

The fund was at a slight disadvantage during the period. Unlike its benchmark, the fund tends to favor value stocks—those that are generally out of favor with investors and typically have lower-than-average price/earnings ratios and higher-than-average dividend yields. Value stocks generally underperformed their growth counterparts for the period.

All sectors were down for the period, but financial stocks were the weakest performers by far, trimming almost 10 percentage points from the fund’s return. Insurance stocks in particular weighed on performance. Although these companies initially held up well amid the credit crisis, many succumbed to market forces later in the period. Poor stock selection in other areas of financials also hurt fund returns.

The industrial sector was also a major sore spot for the fund. Often considered cyclical in nature, industrial stocks tend to rise when the economy is doing well and fall during tougher times. During the six months, widespread weakness in manufacturing, mining, and other capital-intensive industries hurt machinery makers, engineering firms, and transportation companies.

The peer-group expense ratio is derived from data provided by Lipper Inc. and captures information through year-end 2008.

One small positive note: Although the fund’s energy holdings were down for the period, a combination of good stock selection and limited exposure to oil equipment companies helped the fund perform better than its benchmark in this area of the market.

Diversification is important regardless of market conditions

The period ended March 31 was a very difficult time for the U.S. stock market. As the recession deepened, it affected all areas of the market and left investors feeling anxious and uncertain.

Although the market’s volatility can be jarring, it’s important not to let short-term extremes blind us to the long-term case for equities. The stock market’s recent declines are an unavoidable, if extreme, trade-off for the potential to produce superior returns in the long term.

At Vanguard, we encourage investors to build a portfolio that is diversified across asset classes, including stocks, bonds, and money market funds, with the proportions determined by your long-term investment goals. Diversification can provide you with some protection from extreme market swings; however, even a well-balanced portfolio isn’t immune to the difficult market conditions we’ve experienced during the past six months.

Still, we believe that broad diversification among and within asset classes is the right long-term policy, and can position you to weather the occasional storm while helping you benefit from the inevitable return to better times. The Growth and Income Fund can play an important role in such a portfolio.

Thank you for entrusting your assets to Vanguard.

Sincerely,

F. William McNabb III

Advisor’s Report

For the six-month period ended March 31, 2009, the Standard & Poor’s 500 Index (S&P 500) returned about –31%. In the fourth quarter of 2008, markets fell precipitously as it became increasingly clear that the ongoing credit crisis would result in an extended global recession. The September bankruptcy of investment banking firm Lehman Brothers worsened the precarious state of the credit markets, and the S&P 500 returned –23% for October and November combined. The U.S. government progressively increased its interventions, with the passage of the TARP plan in October and monetary easing by the Federal Reserve, including its December reduction of the target federal funds rate to between 0% and 0.25%.

At the start of 2009, hopes for a comprehensive bailout after President Obama’s inauguration faded. Stocks fell anew as economic metrics worsened and Congress debated the bailout package. The package was eventually passed in February, but the economy continued to worsen. However, the tide turned on March 10, when Citigroup CEO Vikram Pandit said the firm was profitable year-to-date through February; other financial services firms announced similar positive news. Soon, following some early month-over-month positive economic data, a rally was under way and the market—led by the financial services sector—rose sharply in March.

As of quarter-end, the markets continued to be highly dependent on government support. As we look ahead, the Federal Reserve and the Obama administration have a difficult balancing act. If they reduce government aid too quickly, the economy may collapse again. If they continue the stimulus for too long, significant inflation could result.

Our fund’s shortfalls

The fund underperformed the S&P 500 for the half-year. Underperformance was primarily attributable to stock selection, although several small industry/sector tilts also detracted from performance, including our underweighted exposure to the relatively strong telecommunications sector.

Overall, the stocks that were rated most attractive in our ranking process underperformed the benchmark during the period. Our process seeks stocks with strong momentum at attractive valuations, and, during the period, neither of these elements was rewarded in the market. However, our portfolio tilt toward companies with lower debt levels—which was implemented during the credit crisis—added value over the period and helped to offset the overall underperformance of the portfolio.

Stock selection was weakest among industrial and health care holdings. In the industrial sector, an overweighting to General Electric had a negative impact on the fund. Concern about asset quality and earnings at GE Capital, the company’s financial services arm, created a drag on the stock’s performance. Ingersoll-Rand also underperformed, as the slumping economy hurt sales for the industrial parts maker. In the health care sector, medical equipment maker Stryker struggled during the period, as growth slowed amid the drop in hospital budgets.

Our fund’s successes

Stock selection was considerably more favorable among technology and energy holdings. In the technology sector, Adobe Systems—which we recently added to the portfolio—was a strong performer, as it met revenue expectations and controlled costs during the period. In the energy sector, Southwestern Energy added to performance as a result of its strong growth in oil and gas production and reserves. Finally, our holdings of several discount retailers, including Wal-Mart and Family Dollar Stores, contributed to performance. These discount retailers benefited from the current price-conscious consumer climate.

During the period, financial services companies, banks in particular, received significant investor attention. Overall, the portfolio’s bank industry holdings performed slightly better than those in the benchmark. Several positions, including an overweighting in Bank of America and an underweighting to the better-performing JPMorgan Chase, detracted from performance. However, overall, we benefited from not holding certain banks, such as Citigroup, and from holding relatively better-performing banks, such as Northern Trust and Hudson City Bancorp.

The fund’s positioning

We have and will continue to emphasize stocks with strong momentum and reasonable prices. These stocks have historically represented the most desirable market segment. At the same time, in the current highly volatile environment, we have continued to be particularly watchful of our risk controls. We have strictly limited industry and sector differences, compared with the S&P 500—particularly those, like financials and energy, that have exhibited the most volatile performances. In addition, we continue to avoid overexposure to leverage and are maintaining a slight tilt toward less-leveraged firms, which has proven beneficial in the recent period.

Growth and Income Fund

Notes to Financial Statements

Vanguard Growth and Income 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 Admiral Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. Admiral Shares are designed for investors who meet certain administrative, service, tenure, and account-size criteria.

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 objective of maintaining full exposure to the stock market while maintaining liquidity. The fund may purchase or sell futures contracts to achieve a desired level of investment, whether to accommodate portfolio turnover or cash flows from capital share transactions. 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 on federal income tax returns for all open tax years (tax years ended September 30, 2005–2008) and for the period ended March 31, 2009, 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.

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 the income earned on investing cash collateral, less expenses associated with the loan.

Growth and Income Fund

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. Mellon Capital Management Corporation (formerly Franklin Portfolio Associates, LLC) provides investment advisory services to the fund for a fee calculated at an annual percentage rate of average net assets. The basic fee is subject to quarterly adjustments based on the fund’s performance for the preceding three years relative to the S&P 500 Index. For the six months ended March 31, 2009, the investment advisory fee represented an effective annual basic rate of 0.10% of the fund’s average net assets before a decrease of $919,000 (0.04%) based on performance.

C. The Vanguard Group furnishes at cost 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 March 31, 2009, the fund had contributed capital of $968,000 to Vanguard (included in Other Assets), representing 0.03% of the fund’s net assets and 0.39% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

D. The fund has asked its investment advisor to direct certain security trades, subject to obtaining the best price and execution, to brokers who have agreed to rebate to the fund part of the commissions generated. Such rebates are used solely to reduce the fund’s management and administrative expenses. For the six months ended March 31, 2009, these arrangements reduced the fund’s expenses by $283,000 (an annual rate of 0.01% of average net assets).

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.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at September 30, 2008, the fund had available realized losses of $570,743,000 to offset future net capital gains through September 30, 2017. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending September 30, 2009; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

Growth and Income Fund

At March 31, 2009, the cost of investment securities for tax purposes was $4,946,533,000. Net unrealized depreciation of investment securities for tax purposes was $1,263,445,000, consisting of unrealized gains of $157,801,000 on securities that had risen in value since their purchase and $1,421,246,000 in unrealized losses on securities that had fallen in value since their purchase.

At March 31, 2009, the aggregate settlement value of open futures contracts expiring in June 2009 and the related unrealized appreciation (depreciation) were:

			($000)
	Number of	Aggregate	Unrealized
	Long (Short)	Settlement	Appreciation
Futures Contracts	Contracts	Value	(Depreciation)
S&P 500 Index	290	57,623	2,070

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

F. During the six months ended March 31, 2009, the fund purchased $1,641,479,000 of investment securities and sold $1,842,885,000 of investment securities, other than temporary cash investments.

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

H. In September 2006, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 157 (“FAS 157”), “Fair Value Measurements.” FAS 157 establishes a framework for measuring fair value and expands disclosures about fair value measurements in financial statements.

The various inputs that may be used to determine the value of the fund’s investments are summarized in three broad levels. The inputs or methodologies used for valuing 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 March 31, 2009, based on the inputs used to value them:

	Investments	Futures
	in Securities	Contracts
Valuation Inputs	($000)	($000)
Level 1—Quoted prices	3,675,641	2,070
Level 2—Other significant observable inputs	7,447	—

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.

Six Months Ended March 31, 2009
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
Growth and Income Fund	9/30/2008	3/31/2009	Period¹
Based on Actual Fund Return
Investor Shares	$1,000.00	$673.25	$1.50
Admiral Shares	1,000.00	673.56	0.92
Based on Hypothetical 5% Yearly Return
Investor Shares	$1,000.00	$1,023.14	$1.82
Admiral Shares	1,000.00	1,023.83	1.11

1 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 0.36% for Investor Shares and 0.22% for Admiral 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.

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.

Glossary

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.

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.

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.

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 157 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 www.vanguard.com.

President’s Letter

Dear Shareholder,

During what was an extremely difficult six months for the U.S. stock market, returns for the Vanguard Structured Equity Funds ranged from about –27% for the Structured Large-Cap Growth Fund to about –36% for the Structured Large-Cap Value Fund. The other two funds, the Structured Large-Cap Equity Fund and the Structured Broad Market Fund, both returned about –32%. All four funds underperformed their benchmarks for the period.

The ongoing recession affected all corners of the market during the six-month period. The widespread volatility resulted in negative returns for all sectors for the four Structured Equity Funds. The funds suffered their most significant losses in the financial, energy, industrial, and information technology sectors—all of which were severely weakened by the troubled economy.

Extreme distress dappled with glimmers of hope

The six months ended March 31 witnessed extreme distress in global stock markets, with both U.S. and international stocks returning about –31%. The embattled financial sector continued to struggle, prompting regulators in the United States and abroad to take evermore-aggressive actions to help the big banks fortify their fragile balance sheets.

Even as the gloom intensified, a few signs of recovery appeared on the horizon. Toward the end of the period, the swift contraction in manufacturing activity seemed to lessen. And throughout the six months, news from the housing sector seemed to improve. From their lows in early March through the end of the period, global stock markets generated a double-digit return.

Credit-market turmoil provoked dramatic response

The Federal Reserve Board responded to the credit-market and economic crises with a dramatic easing of monetary policy, reducing its target for short-term interest rates to an all-time low of 0% to 0.25%. The Fed also created new programs designed to bring borrowers and lenders back to the market. For the six-month period, the Barclays Capital U.S. Aggregate Bond Index returned 4.70% on the strength of Treasuries and other government-backed bonds. The broad municipal bond market returned 5.00%.

Trouble in all sectors led to disappointing results

The Vanguard Structured Equity Funds are designed to maintain index-like risk profiles while producing index-beating returns through superior stock selection. During an exceptionally difficult six months for U.S. stocks, the four funds fell short of this goal.

On an absolute basis, the Structured Large-Cap Growth Fund had the best results for the period, while the Structured Large-Cap Value Fund was the worst performer of the bunch. This came as no surprise, since value stocks generally underperformed their growth counterparts for the period. Meanwhile, the performance of the Structured Large-Cap Equity Fund—which is a blend of large-cap growth and large-cap value stocks—fell somewhere in the middle. Unlike the three other funds, the Structured Broad Market Fund has exposure to small- and mid-capitalization stocks, which underperformed large-cap stocks. Despite this exposure, the fund performed about the same as its large-cap blend counterpart.

Although there were no true bright spots during the six-month period, some sectors were hit harder by the flailing economy than others. As the credit crisis continued, it affected all corners of the financial sector, from investment banks to insurance companies. Many high-profile information technology stocks plummeted as the global economic downturn hindered sales of PCs and other tech products. Industrial and energy stocks also suffered.

All four funds trailed their benchmark indexes. The Structured Large-Cap Value Fund had the smallest margin of shortfall—about 0.5 percentage point—while the Structured Large-Cap Equity Fund had the greatest, a little more than 1 percentage point.

Relative to their respective benchmarks, the funds’ weakest performances came from the energy, materials, and information technology sectors. Thanks to good stock selection in the consumer discretionary, financial, and health care sectors, the funds held up better in these areas than their indexes.

Diversification is important regardless of market conditions

The six months ended March 31 represented a terrible time for the U.S. stock market. As the recession deepened, it affected all areas of the market and left both investors and investment managers feeling anxious and uncertain.

Although the market’s volatility can be jarring, it’s important not to let short-term extremes blind us to the long-term case for equities. The stock market’s recent declines are an unavoidable, if extreme, trade-off for stocks’ potential to produce superior returns in the long run.

At Vanguard, we encourage investors to build a portfolio that is diversified across asset classes, including stocks, bonds, and

money market funds, with the proportions determined by their institution’s long-term investment goals.

Although even a well-balanced portfolio isn’t immune to the difficult market conditions we’ve experienced during the past six months, we believe that broad diversification among and within asset classes represents the right policy, and can position your institution to weather the occasional storm while helping it to benefit from the inevitable return to better times. As part of a well-diversified long-term strategy, we believe the Vanguard Structured Equity Funds can play an integral role in helping your organization reach its investment goals.

Thank you for entrusting your assets to Vanguard.

Sincerely,

William McNabb III

President and Chief Executive Officer

Advisor’s Report

The six months ended March 31, 2009 were a difficult period for Vanguard’s Structured Equity Funds. All the funds showed double-digit losses and lagged their benchmarks for the period.

The investment environment

The attractively valued, high-quality stocks that we prefer underperformed the market during the past six months.

We base our view on judgment and empirical evidence. In our judgment, although the market is relatively effective in assigning prices to stocks, investors as a group can still overreact to new information. This overreaction can cause prices to diverge a bit from “true” or “fair” value, providing opportunities to profit from these discrepancies.

We identify potentially attractive stocks by looking at multiple signals. Market participants send some signals, such as measures of relative performance or changes in analysts’ opinions. Other signals are provided by the company’s management, such as changes in capital spending or dividends. Finally, there are valuation signals, such as price/earnings ratios and yields.

Over time, our signals have indicated future outperformance, although there are periods, sometimes measured in years, when our models are not effective. Nonetheless, consistent exposure to these signals does seem to be rewarded over time.

Given our opinion that it is better to own attractive stocks at low multiples, we feel that our portfolios are well-positioned for a market rebound.

Here are brief reviews of each fund’s performance relative to its benchmark.

Structured Large-Cap Equity Fund

Our best performance was in the capital goods industry, where our underweighting in General Electric was very helpful. Automobile and bank holdings also performed well, led by Ford and PNC Financial. Materials stocks underperformed, with United States Steel our worst pick.

Structured Large-Cap Growth Fund

Consumer services was our best-performing industry, led by ITT Educational Services. Diversified financial stocks and health care holdings helped performance, while materials stocks were our worst performers, led by United States Steel.

Structured Large-Cap Value Fund

Consumer durables stocks were our best-performing holdings, helped by our positions in Stanley Works and Hasbro Bradley. Consumer services and transportation companies also performed well. Technology hardware firms reduced performance, with NCR dropping significantly. Pharmaceutical stocks also weakened performance.

Structured Broad Market Fund

Consumer durables were our best-performing stocks, led by VF Corp. Automobiles also contributed positively. Pharmaceuticals, particularly King Pharmaceutical, hurt returns.

Conclusion

Our investment philosophy is to buy high-quality stocks at relatively low valuations, relying on a process that focuses on multiple inputs. In constructing a portfolio from these inputs, we believe that a low level of relative risk is preferable, as are low costs. We have been successful in keeping our tracking error within our expectations, and while we are disappointed that our portfolios did not outpace our benchmarks, we are confident in our preference for low-valuation, high-quality stocks. Although these stocks have not been favored by the market over the six-month period of this report, we believe in their long-term prospects.

We thank you for your investment and look forward to the rest of the fiscal year.

Structured Large-Cap Equity Fund

Notes to Financial Statements

Vanguard Structured Large-Cap Equity 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: Institutional Shares and Institutional Plus Shares. Institutional Shares are designed for investors who meet certain administrative and service criteria and invest a minimum of $5 million. Institutional Plus Shares are available to investors who invest a minimum amount of $200 million ($100 million for investors with total Vanguard investments of at least $1 billion).

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 on federal income tax returns for all open tax years (tax years ended September 30, 2006–2008), and for the period ended March 31, 2009, 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.

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 March 31, 2009, the fund had contributed capital of $115,000 to Vanguard (included in Other Assets), representing 0.03% of the fund’s net assets and 0.05% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

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

During the six months ended March 31, 2009, the fund realized $20,147,000 of net capital losses resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such losses are not taxable losses to the fund, they have been reclassified from accumulated net realized losses to paid-in capital.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at September 30, 2008, the fund had available realized losses of $61,104,000 to offset future net capital gains through September 30, 2017. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending September 30, 2009; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At March 31, 2009, the cost of investment securities for tax purposes was $575,470,000. Net unrealized depreciation of investment securities for tax purposes was $132,663,000, consisting of unrealized gains of $7,524,000 on securities that had risen in value since their purchase and $140,187,000 in unrealized losses on securities that had fallen in value since their purchase.

Structured Large-Cap Equity Fund

At March 31, 2009, the aggregate settlement value of open futures contracts expiring in June 2009 and the related unrealized appreciation (depreciation) were:

Futures Contracts	Contracts	Value	(Depreciation)
S&P 500 Index	2	398	38
E-mini S&P 500 Index	3	119	1

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

D. During the six months ended March 31, 2009, the fund purchased $328,486,000 of invest

Structured Large-Cap Growth Fund

Notes to Financial Statements

Vanguard Structured Large-Cap Growth 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: Institutional Shares and Institutional Plus Shares. Institutional Shares are designed for investors who meet certain administrative and service criteria and invest a minimum of $5 million. Institutional Plus Shares are available to investors who invest a minimum amount of $200 million ($100 million for investors with total Vanguard investments of at least $1 billion).

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 on federal income tax returns for all open tax years (tax years ended September 30, 2007–2008) and for the period ended March 31, 2009, 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.

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.

Structured Large-Cap Growth 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 March 31, 2009, the fund had contributed capital of $11,000 to Vanguard (included in Other Assets), representing 0.03% of the fund’s net assets and 0.00% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at September 30, 2008, the fund had available realized losses of $3,839,000 to offset future net capital gains through September 30, 2017. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending September 30, 2009; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At March 31, 2009, the cost of investment securities for tax purposes was $50,217,000. Net unrealized depreciation of investment securities for tax purposes was $9,139,000, consisting of unrealized gains of $1,436,000 on securities that had risen in value since their purchase and $10,575,000 in unrealized losses on securities that had fallen in value since their purchase.

At March 31, 2009, the aggregate settlement value of open futures contracts expiring in June 2009 and the related unrealized appreciation (depreciation) were:

			($000)
	Number of	Aggregate	Unrealized
	Long (Short)	Settlement	Appreciation
Futures Contracts	Contracts	Value	(Depreciation)
E-mini S&P 500 Index	4	159	(6)

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

Structured Large-Cap Value Fund

Notes to Financial Statements

Vanguard Structured Large-Cap Value 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: Institutional Shares and Institutional Plus Shares. Institutional Shares are available to investors who invest a minimum of $5 million. Institutional Plus Shares are available to investors who invest a minimum amount of $200 million ($100 million for investors with total Vanguard investments of at least $1 billion). The fund has not issued any Institutional Shares through March 31, 2009.

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 on federal income tax returns for all open tax years (tax years ended September 30, 2007–2008) and for the period ended March 31, 2009, 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.

Structured Large-Cap Value 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 March 31, 2009, the fund had contributed capital of $10,000 to Vanguard (included in Other Assets), representing 0.03% of the fund’s net assets and 0.00% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at September 30, 2008, the fund had available realized losses of $4,504,000 to offset future net capital gains through September 30, 2017. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending September 30, 2009; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At March 31, 2009, the cost of investment securities for tax purposes was $51,444,000. Net unrealized depreciation of investment securities for tax purposes was $14,084,000, consisting of unrealized gains of $978,000 on securities that had risen in value since their purchase and $15,062,000 in unrealized losses on securities that had fallen in value since their purchase.

At March 31, 2009, the aggregate settlement value of open futures contracts expiring in June 2009 and the related unrealized appreciation (depreciation) were:

			($000)
	Number of	Aggregate	Unrealized
	Long (Short)	Settlement	Appreciation
Futures Contracts	Contracts	Value	(Depreciation)
E-mini S&P 500 Index	1	40	2

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

At March 31, 2009, the fund had contributed capital of $53,000 to Vanguard (included in Other Assets), representing 0.03% of the fund’s net assets and 0.02% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at September 30, 2008, the fund had available realized losses of $27,520,000 to offset future net capital gains through September 30, 2017. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending September 30, 2009; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.

At March 31, 2009, the cost of investment securities for tax purposes was $266,451,000. Net unrealized depreciation of investment securities for tax purposes was $60,943,000, consisting of unrealized gains of $4,335,000 on securities that had risen in value since their purchase and $65,278,000 in unrealized losses on securities that had fallen in value since their purchase.

At March 31, 2009, the aggregate settlement value of open futures contracts expiring in June 2009 and the related unrealized appreciation (depreciation) were:

			($000)
	Number of	Aggregate	Unrealized
	Long (Short)	Settlement	Appreciation
Futures Contracts	Contracts	Value	(Depreciation)
E-mini S&P 500 Index	10	397	(14)

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

Institutional Plus Shares	1,000.00	1,024.13	0.81

1 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 0.24% for the Structured Large-Cap Equity Fund Institutional Shares, 0.16% for the Institutional Plus Shares; 0.24% for the Structured Large-Cap Growth Fund Institutional Shares, 0.16% for the Institutional Plus Shares; 0.16% for the Structured Large-Cap Value Fund Institutional Plus Shares; 0.25% for the Structured Broad Market Fund Institutional Shares, 0.16% for the Institutional Plus Shares. The dollar amounts shown as “Expenses Paid” are equal to the annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent six-month period, then divided by the number of days in the most recent 12-month period.

Trustees Approve Advisory Arrangement

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

The board based its decision upon an evaluation of the advisor’s investment staff, portfolio management process, and performance. The trustees considered the factors discussed below, among others. However, no single factor determined whether or not the board approved the arrangement. Rather, it was the totality of the circumstances that drove the board’s decision.

Nature, extent, and quality of services

The board considered the quality of each fund’s investment management since its inception, and took into account the organizational depth and stability of the advisor. Vanguard has been managing investments for more than 25 years. George U. Sauter, Vanguard managing director and chief investment officer, has been in the investment management business since 1985. Mr. Sauter has led the Quantitative Equity Group since 1987. The Quantitative Equity Group adheres to a sound, disciplined investment management process; the team has considerable experience, stability, and depth.

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

Investment performance

The board considered the performance of each fund since its inception, including any periods of outperformance or underperformance of the relevant benchmark and peer group. The board concluded that the advisor has carried out each fund’s investment strategy in disciplined fashion, and that performance results have been within competitive norms. Information about the funds’ most recent performance can be found on the Performance Summary pages of this report.

Cost

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

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

The benefit of economies of scale

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

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