Chairman’s Letter

Dear Shareholder,

The Investor Shares and Admiral Shares of Vanguard Growth and Income Fund returned 8.9% and 9.0%, respectively, during the fiscal half-year ended March 31, 2007. The fund met its goal of outperforming the Standard & Poor’s 500 Index while maintaining a risk profile similar to that of the index. The fund also outpaced the average return of large-capitalization core funds, as shown in the table on page 1.

The fund’s superior stock picks in the energy, consumer discretionary, industrials, information technology, and materials sectors more than compensated for subpar stock selections in other sectors.

Six-month stock market return reflected disparate market moods

The broad U.S. stock market stitched together a solid six-month return from patches of strength and weakness. Stock prices rallied at the start of the period, pulled back in February—in part, a reaction to the Chinese market’s swoon—then recovered in March, buoyed by generally benign economic and corporate-profit reports.

Small-capitalization stocks outpaced large-caps, and international stocks outperformed their U.S. counterparts—patterns that have been in place for much of the past few years.

As the Fed sat tight, bonds produced coupon-like returns

The Federal Reserve Board remained offstage during the six months, keeping its target for the federal funds rate at 5.25% throughout the period. Despite some interim back-and-forth, longer-term bond yields finished the period pretty much where they started. With rates—and prices—more or less stable, bonds’ returns were consistent with their coupons.

The broad taxable bond market returned 2.8% for the six-month period. The municipal securities market posted a return of 1.9%. Money market instruments, one of the fixed income market’s bright spots in recent months, returned 2.5% for the half-year, as measured by the Citigroup 3-Month Treasury Bill Index.

Superior stock picking boosts fund returns

The Growth and Income Fund seeks to maintain a risk level similar to that of the S&P 500 Index by mirroring the benchmark’s sector weights, but it also endeavors to outpace the S&P 500 through superior stock selection within each sector. For the most part, the fund achieved this goal in the first half of fiscal 2007.

For example, the fund maintained a weighting in the energy sector that was about the same as that of its benchmark. But the index sector’s return was 13.5%, compared with a return of 18.4% for the fund’s energy stocks, reflecting the strong performance of the fund’s sizable holdings in companies such as XTO Energy and Marathon Oil.

The fund’s advisor, Franklin Portfolio Associates, uses a battery of computer models to decide which stocks to buy or sell within each sector. Franklin’s models favor reasonably valued stocks, which typically have price/earnings ratios a bit below those of the index.

In addition to energy, the consumer discretionary, industrials, information technology, and materials sectors were the major contributors to the fund’s return. Notable stock selections included International Business Machines, media company News Corporation, and truck manufacturer PACCAR.

The fund was less successful in other sectors such as utilities and health care. Although the fund’s holdings delivered generally positive returns, their performances trailed those of similar companies in the index. The fund had relatively light exposure to solidly performing electric utility stocks, for example, many of which registered double-digit increases during the period.

Maintain a balanced and diversified portfolio

Vanguard Growth and Income Fund has performed well during the most recent fiscal half-year. As always, however, we urge you to look beyond the recent performance of your individual investments and understand the role each fund plays in your portfolio.

The Growth and Income Fund provides broad, low-cost exposure to large-cap U.S. stocks. It incorporates diversification and risk-control benefits similar to those of an index fund while also offering the potential to best the index. We recommend that you consider this fund as a core holding in a portfolio that is further diversified across stock holdings and other asset classes as well—consistent, of course, with your goals, time horizon, and tolerance for risk.

Thank you for entrusting your assets to Vanguard.

Sincerely,

Advisor’s Report

Much of the U.S. economic picture has remained unchanged over the last six months. Although statistical data continue to give mixed signals, overall they suggest that the economy is still expanding, albeit at a slower pace and with a rising risk of a recession sometime in late 2007 or in 2008.

The ultimate impact of the housing industry contraction and the related subprime lending debacle remains unclear. The situation is certainly causing anxiety and difficulties for those directly involved, but the overall economy may prove able to absorb the losses without undue disruption. And while there are other signs that the economy’s current expansion is getting stretched, we do not see the extreme cases of resource pricing that would normally precede a sharp rise in interest rates, which in turn would trigger a contraction. If we do slide into a recession, there is a distinct possibility that it will be shallow and short-lived.

If the stock market is a leading indicator of U.S. economic activity, we should feel some relief. Domestic equities have continued to perform well as corporate profit growth has kept pace with higher prices. From a valuation perspective, large-capitalization U.S. equities appear reasonably attractive. And within the large-cap arena, the pricing of stocks with a tilt toward growth characteristics and higher “quality” may be particularly attractive. While this may not be the time to maximize your exposure to large-cap U.S. equities, it may also be too early to reduce your exposure.

Our successes

The fund’s performance, both in absolute terms and compared with our benchmark, was positive for the six months through March 31. Stock selection was particularly good in the consumer discretionary, information technology, energy, and materials sectors. Stocks that did especially well for the fund—outperforming their industry groups—included XTO Energy (U.S. oil and gas producer), IBM, News Corporation, J.C. Penney, PACCAR (a truck manufacturer), and United States Steel. All of these companies exhibited reasonable or compelling stock valuations coupled with earnings results in line with or exceeding expectations.

While sector tilts (measured as the difference between sector weightings in the portfolio and the S&P 500 Index) are deliberately minimized in the Growth and Income Fund, they are not forced to zero. During the six months, the fund’s modest sector tilts in aggregate improved our relative return. In addition, the fund’s tendency to hold stocks that on average have a lower price-to-earnings ratio than the overall S&P 500 figure enhanced relative performance during the October–December period. The fund’s tilt toward stocks with near-term positive price momentum was a drag on performance until the final month of the period, when momentum was strongly rewarded.

Our shortfalls

Holdings that hurt our overall results included Texas Utilities (despite a takeover bid, the stock had an essentially flat return for the period, and it underperformed other utilities), Lehman Brothers (broker and investment banker), Johnson & Johnson (the health care product giant), and Molex (electronics). Our “evergreen” tilts toward earnings yield and momentum had mixed results for the period. The earnings-yield tilt has detracted from recent performance; the momentum tilt, as noted above, was a drag on results until a strong turnaround in March.

The fund’s positioning

While we are continually adjusting individual holdings—trimming or selling out positions that are no longer attractive, reinvesting the proceeds in top-ranked stocks—we have made no significant changes in the overall structure of the fund. Given the historically low level of risk in U.S. equities today (measured in terms of individual stock price volatility), we are able to meet our risk-control objectives while holding fewer names in the fund. We are also allowing ourselves slightly more leeway in terms of industry and sector weightings relative to the benchmark because of the low cross-sectional risk of U.S. stocks.

But these are minor adjustments within the context of providing our shareholders a diversified portfolio focused on large-cap U.S. equities. And we believe strongly in maintaining a consistent exposure to large-cap U.S. equities as one part of an overall investment program.

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 files reports with the SEC under the company name Vanguard Quantitative Funds. 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 4:00 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. Accordingly, no provision for federal income taxes is required in the 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.

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. 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, 2007, the investment advisory fee represented an effective annual basic rate of 0.09% of the fund’s average net assets, with no adjustment required 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, 2007, the fund had contributed capital of $726,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.73% 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. The fund’s custodian bank has also agreed to reduce its fees when the fund maintains cash on deposit in the non-interest-bearing custody account. For the six months ended March 31, 2007, these arrangements reduced the fund’s management and administrative expenses by $653,000 and custodian fees by $10,000. The total expense reduction represented an effective annual rate of 0.01% of the fund’s 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, 2006, the fund had available realized losses of $130,065,000 to offset future net capital gains through September 30, 2011. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending September 30, 2007; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance(s) above.

At March 31, 2007, the cost of investment securities for tax purposes was $6,731,877,000. Net unrealized appreciation of investment securities for tax purposes was $1,116,373,000, consisting of unrealized gains of $1,182,812,000 on securities that had risen in value since their purchase and $66,439,000 in unrealized losses on securities that had fallen in value since their purchase.

At March 31, 2007, the aggregate settlement value of open futures contracts expiring in June 2007 and the related unrealized appreciation (depreciation) were:

			($000)
	Number	Aggregate	Unrealized
	of Long	Settlement	Appreciation
Futures Contracts	Contracts	Value	(Depreciation)
S&P 500 Index	110	39,358	1,036

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, 2007, the fund purchased $3,861,140,000 of investment securities and sold $4,001,896,000 of investment securities, other than U.S. government securities and temporary cash investments.

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

H. In June 2006, the Financial Accounting Standards Board issued Interpretation No. 48 (“FIN 48”), “Accounting for Uncertainty in Income Taxes.” FIN 48 establishes the minimum threshold for recognizing, and a system for measuring, the benefits of tax-return positions in financial statements. FIN 48 will be effective for the fund’s fiscal year beginning October 1, 2007. Management is in the process of analyzing the fund’s tax positions for purposes of implementing FIN 48; based on the analysis completed to date, management does not believe the adoption of FIN 48 will result in any material impact to the fund’s financial statements.

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 table below 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, 2007
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
Growth and Income Fund	9/30/2006	3/31/2007	Period¹
Based on Actual Fund Return
Investor Shares	$1,000.00	$1,088.98	$1.87
Admiral Shares	1,000.00	1,089.87	0.99
Based on Hypothetical 5% Yearly Return
Investor Shares	$1,000.00	$1,023.14	$1.82
Admiral Shares	1,000.00	1,023.98	0.96

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 0.19% 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 any transactional costs or account maintenance fees. They do not include your fund’s low-balance fee, which is described in the prospectus. If this 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 the appropriate fund 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%. A fund’s beta should be reviewed in conjunction with its R-squared (see definition below). 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.

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.

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 snapshot of a fund’s income from interest and dividends. The yield, expressed as a percentage of the fund’s net asset value, is based on income earned over the past 30 days and is annualized, or projected forward for the coming year. The index yield is based on the current annualized rate of income provided by securities in the index.

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.

Our independent board members bring distinguished backgrounds in business, academia, and public service to their task of working with Vanguard officers to establish the policies and oversee the activities of the funds. Among board members’ responsibilities are selecting investment advisors for the funds; monitoring fund operations, performance, and costs; reviewing contracts; nominating and selecting new trustees/directors; and electing Vanguard officers.

Each trustee serves a fund until its termination; or until the trustee’s retirement, resignation, or death; or otherwise as specified in the fund’s organizational documents. Any trustee may be removed at a shareholders’ meeting by a vote representing two-thirds of the net asset value of all shares of the fund together with shares of other Vanguard funds organized within the same trust. The table on these two pages shows information for each trustee and executive officer of the fund. The mailing address of the trustees and officers is P.O. Box 876, Valley Forge, PA 19482.

Chairman’s Letter

Dear Shareholder,

Since I wrote to you six months ago, Vanguard’s Structured Large-Cap Equity Fund has been joined by three other funds—the Structured Large-Cap Growth, Structured Large-Cap Value, and Structured Broad Market Funds. Each fund works to provide consistent above-benchmark returns while maintaining benchmark risk levels. And each fulfilled its mandate during the first half of the 2007 fiscal year.

In a sense, the newest funds are actually old friends. They had existed at Vanguard in a different organizational form, as trusts. Because they continue to be managed by our Quantitative Equity Group, and have the same investment objectives, strategies, policies, and risks, the funds have adopted the performance history of the trusts.

For details about the performance of each fund, see the table on page 1.

Six-month stock market return reflected disparate market moods

Small-capitalization stocks outpaced large-caps, and international stocks outperformed their U.S. counterparts—patterns that have been in place for much of the past few years.

As the Federal Reserve sat tight, bonds produced coupon-like returns

The Federal Reserve Board remained offstage during the six months, keeping its target for the federal funds rate at 5.25% throughout the period. Despite some interim back-and-forth, longer-term bond yields finished the period pretty much where they started. With rates—and prices—more or less stable, returns from bonds were consistent with their coupons.

The funds met their goals for both risk and return

Our structured equity funds have a common approach to risk and return. Each seeks to match the risk profile of its benchmark index by maintaining sector weightings and other characteristics in line with those of the benchmark. At the same time, each seeks to beat its

benchmark by relying exclusively on stock selection—overweighting or underweighting individual stocks within tightly controlled limits, while remaining highly diversified overall.

The stock market’s gyrations during the fiscal half-year tested the funds’ risk-control techniques—a test the funds successfully passed. The funds also met their performance goal by edging past their benchmarks.

A look at the performance of the structured equity portfolios

The Structured Large-Cap Equity Fund surpassed the return of the benchmark Standard & Poor’s 500 Index thanks to stock selection in the fund’s smallest and largest sectors—materials and financials, respectively. In the materials group, steel stocks, including United States Steel and Nucor, drove returns. The leading contributors within financials were property and casualty insurers and capital markets companies, such as Ameriprise Financial.

The fund’s industrials and energy sectors were the next-largest contributors, followed by consumer staples and health care. Telecommunication services holdings equaled the benchmark’s return. The information technology, consumer discretionary, and utilities sectors detracted from relative performance.

The Structured Large-Cap Growth Fund handily beat its benchmark, the Russell 1000 Growth Index, for the six-month period. The major contributors to return were industrials and information technology, among the fund’s largest sectors, as well as materials, one of the fund’s smallest. Individual stocks that helped the fund to outperform included Avnet, an Internet services provider; Celanese, the chemical company; and JLG Industries, the machinery manufacturer. The only sectors that detracted from the fund’s performance compared with the index were consumer staples and financials.

The Structured Large-Cap Value Fund performed in line with the benchmark Russell 1000 Value Index during the period. In most sectors, the fund’s returns hovered slightly above or slightly below those of the index groups. Holdings in the materials, consumer discretionary, industrials, energy, and health care sectors boosted the relative return, while those in the information technology, financials, and utilities sectors detracted. The fund’s consumer staples and telecommunication services stocks matched the index returns.

The Structured Broad Market Fund invests in growth and value stocks across all capitalizations. One of its smallest sectors—materials—contributed the most to its outperformance of the Russell 3000 Index during the six months. Within this sector, stocks in the steel industry, especially United States Steel and Steel Dynamics, were the leading contributors.

The industrials and telecommunications services sectors were the other major sources of outperformance. Lesser contributions came from the fund’s largest sector, financials, and from the consumer discretionary and health care groups. The return from the fund’s energy stocks matched that of the index sector. Consumer staples, information technology, and utilities detracted from the relative return.

You don’t always need home runs to succeed

Vanguard’s structured equity funds seek to provide consistent above-benchmark returns while matching key characteristics of their benchmarks to maintain tight control over risk.

Another way of looking at the funds’ investment approach is to repeat a baseball metaphor that I’ve used before, and that has the dual advantage of being colorful while getting to the essence of the structured funds’ strategy. The Vanguard structured equity funds don’t try to hit grand slams. Instead, they aim to consistently hit singles and doubles, edging past their benchmarks over time.

Thank you for entrusting your assets to Vanguard.

Sincerely,

John J. Brennan

Chairman and Chief Executive Officer

Advisor’s Report

For the six months ending March 31, 2007, all four of Vanguard’s structured equity funds outperformed their benchmarks.

The Structured Large-Cap Equity Fund returned 7.7% for Institutional Shares and 7.8% for Institutional Plus Shares, topping the return of the benchmark S&P 500 Index by 0.4 percentage point.

The Structured Large-Cap Growth Fund’s

Institutional Plus Shares returned 8.1%, outperforming the Russell 1000 Growth Index by 0.9 percentage point.

The Structured Large-Cap Value Fund’s

Institutional Plus Shares returned 9.4%, just beating the 9.3% return of the Russell 1000 Value Index.

The Structured Broad Market Fund’s

Institutional Plus Shares returned 9.1%, outperforming the Russell 3000 Index by 0.6 percentage point. (The fund’s new Institutional Shares, which existed for only part of the period, returned 2.8%.)

Please note: With the exception of the Structured Large-Cap Equity Fund, these portfolios had previously been offered as trusts. During the past six months, the portfolios began offering mutual fund shares. We are reporting on their performance for the entire six-month period, and the Performance Summary pages show their returns since the trusts’ inceptions.

The investment environment

During the fiscal half-year, small- and mid-capitalization stocks once again outperformed their large-cap brethren.

Large stocks, as measured by the MSCI US Large Cap 300 Index, were up about 7%, while the small- and mid-cap stocks each gained about 12%. The entire market, as measured by the MSCI US Investable Market 2500 Index, returned 8.5%.

In our letter to shareholders six months ago, we remarked upon the ability of our structured equity strategy to withstand a spike in market volatility. We again find ourselves reviewing a period during which volatility doubled, but was kept at bay by our tight risk controls.

Our investment process

The heart of our process is our stock selection model. It contains three elements, each of which measures a stock’s attractiveness relative to its capitalization and industry peers. The first element measures a stock’s valuation; the second evaluates earnings quality; and the last considers market sentiment. These three elements are combined into an overall rating for each stock. To construct our portfolios, we combine our stock ratings with risk measures to minimize our exposure to industry and other factors. The resulting portfolio should capture its benchmark’s return plus the result of our model’s stock selection.

To oversimplify, each fund’s performance will have three components: the return of the benchmark, our model’s stock-picking ability, and some amount of “luck.” During the past six months, that third component was positive for each portfolio, enhancing our model’s stock selection. Over the long run, however, we expect that “luck” will average out to zero.

Following are brief reviews of each fund’s performance.

Structured Large-Cap Equity Fund

Our stock-selection model had a good half-year, with all of the components of the model working in synchronization.

Our best performance over the six months was in the materials industry, where our model picked United States Steel and Phelps Dodge, each of which rose dramatically. Ironically, United States Steel was highlighted in our last letter as the source of a significant drag on performance. Our model was also successful in the energy and capital goods industries. Conversely, the model picked Molex, which dropped in value during the period. These disparate results in the same period are typical of a quantitative process like ours and of a portfolio that holds many securities.

Structured Large-Cap Growth Fund

For this fund, the stock-selection model performed strongly in the period, with all three components in sync. Our best performance was in the technology industry, where the model picked Avnet and IBM, each of which rose dramatically. Our model was also successful in the commercial services and transportation industries. Conversely, it led us to purchase Amgen, which dropped in value during the period.

Structured Large-Cap Value Fund

In contrast with the other portfolios, our stock selection model had a mediocre half-year in the Structured Large-Cap Value Fund. The valuation component of the model worked well, but the other two components delivered lackluster results.

Our best six-month performance was in the materials industry, where our model picked Phelps Dodge and Celanese, each of which climbed steeply. Our model was also successful in the energy and consumer durables industries; however, its selection of Pfizer was disappointing, as the stock fell.

Structured Broad Market Fund

Here, too, the stock selection model had a strong half-year, with all of its components working well. We did best in the materials industry, where the model picked United States Steel and Steel Dynamics. Both rose sharply. Our model was also successful in the diversified financials and telecommunications industries. Its selection of Pfizer and Amgen hurt the overall return, however.

Conclusion

The stock-specific risk that we assumed has paid off so far in this fiscal year for three of the funds; the Structured Large-Cap Value Fund has been an exception. We look forward to the remainder of the fiscal year, believing that the funds offer a strong mix of stocks with attractive valuation and growth characteristics relative to their underlying benchmarks.

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 files reports with the SEC under the company name Vanguard Quantitative Funds. The fund offers two classes of shares, Institutional Shares and Institutional Plus Shares. Institutional Shares are available to investors who invest a minimum amount 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).

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 Equity 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, 2007, the fund had contributed capital of $67,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.07% 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. The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year.

At March 31, 2007, the cost of investment securities for tax purposes was $684,024,000. Net unrealized appreciation of investment securities for tax purposes was $45,507,000, consisting of unrealized gains of $53,206,000 on securities that had risen in value since their purchase and $7,699,000 in unrealized losses on securities that had fallen in value since their purchase.

At March 31, 2007, the aggregate settlement value of open futures contracts expiring in June 2007 and the related unrealized appreciation (depreciation) were:

			($000)
		Aggregate	Unrealized
	Number of	Settlement	Appreciation
Futures Contracts	Long Contracts	Value	(Depreciation)
E-mini S&P 500 Index	7	501	(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, 2007, the fund purchased $513,130,000 of investment securities and sold $149,052,000 of investment securities, other than temporary cash investments.

F. In June 2006, the Financial Accounting Standards Board issued Interpretation No. 48 (“FIN 48”), “Accounting for Uncertainty in Income Taxes.” FIN 48 establishes the minimum threshold for recognizing, and a system for measuring, the benefits of tax-return positions in financial statements. FIN 48 will be effective for the fund’s fiscal year beginning October 1, 2007. Management is in the process of analyzing the fund’s tax positions for purposes of implementing FIN 48; based on the analysis completed to date, management does not believe the adoption of FIN 48 will result in any material impact to the fund’s financial statements.

1	Inception was May 16, 2006, for Institutional Shares and May 15, 2006, for Institutional Plus Shares.

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.

3. Federal Income Taxes: The fund intends to qualify as a regulated investment company and distribute all of its taxable income. Accordingly, no provision for federal income taxes is required in the financial statements.

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

Structured Large-Cap Growth 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 the 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 March 31, 2007, the fund had contributed capital of $5,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.01% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

At March 31, 2007, the cost of investment securities for tax purposes was $49,205,000. Net unrealized appreciation of investment securities for tax purposes was $3,892,000, consisting of unrealized gains of $5,583,000 on securities that had risen in value since their purchase and $1,691,000 in unrealized losses on securities that had fallen in value since their purchase.

At March 31, 2007, the aggregate settlement value of open futures contracts expiring in June 2007 and the related unrealized appreciation (depreciation) were:

			($000)
		Aggregate	Unrealized
	Number of	Settlement	Appreciation
Futures Contracts	Long Contracts	Value	(Depreciation)
E-mini S&P 500 Index	1	72	—

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

D. During the period ended March 31, 2007, the fund purchased $10,059,000 of investment securities and sold $9,786,000 of investment securities, other than temporary cash investments.

E. The market value of securities on loan to broker-dealers at March 31, 2007, was $185,000, for which the fund received cash collateral of $190,000.

Structured Large-Cap Growth Fund

F. Pursuant to a plan of reorganization approved by the trustee of Vanguard Fiduciary Trust Company Structured Large-Cap Growth Trust (the “trust”) on July 18, 2006, the trust purchased shares of the fund through a non-taxable in-kind transfer of all of the trust’s investment securities on October 3, 2006, resulting in the issuance of 976,000 fund shares at a net asset value per share of $50.00. The trust’s net assets transferred to the fund were $48,807,000, including net unrealized appreciation of $473,000. On October 4, 2006, the trust liquidated by distributing to unitholders shares of the fund equal to the value of the unitholders’ investments in the trust.

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 files reports with the SEC under the company name Vanguard Quantitative Funds. The fund offers two classes of shares, Institutional Shares and Institutional Plus Shares. Institutional Shares are available to investors who invest a minimum amount 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, 2007.

2. Federal Income Taxes: The fund intends to qualify as a regulated investment company and distribute all of its taxable income. Accordingly, no provision for federal income taxes is required in the 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 the 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 March 31, 2007, the fund had contributed capital of $7,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.01% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

Structured Large-Cap Value Fund

At March 31, 2007, the cost of investment securities for tax purposes was $69,026,000. Net unrealized appreciation of investment securities for tax purposes was $11,083,000, consisting of unrealized gains of $11,374,000 on securities that had risen in value since their purchase and $291,000 in unrealized losses on securities that had fallen in value since their purchase.

D. During the period ended March 31, 2007, the fund purchased $8,713,000 of investment securities and sold $8,143,000 of investment securities, other than temporary cash investments.

E. The market value of securities on loan to broker-dealers at March 31, 2007, was $131,000, for which the fund received cash collateral of $139,000.

F. Pursuant to a plan of reorganization approved by the trustee of Vanguard Fiduciary Trust Company Structured Large-Cap Value Trust (the “trust”) on October 20, 2006, the trust purchased shares of the fund through a non-taxable in-kind transfer of all of the trust’s investment securities on January 18, 2007, resulting in the issuance of 1,309,000 fund shares at a net asset value per share of $60.09. The trust’s net assets transferred to the fund were $78,661,000, including net unrealized appreciation of $10,857,000. On January 19, 2007, the trust liquidated by distributing to unitholders shares of the fund equal to the value of the unitholders’ investments in the trust.

G. Capital shares issued and redeemed were:

The fund’s trustees and officers are also directors and officers of Vanguard.

At March 31, 2007, the cost of investment securities for tax purposes was $106,569,000. Net unrealized appreciation of investment securities for tax purposes was $14,843,000, consisting of unrealized gains of $17,279,000 on securities that had risen in value since their purchase and $2,436,000 in unrealized losses on securities that had fallen in value since their purchase.

	Number of	Settlement	Appreciation
Futures Contracts	Long Contracts	Value	(Depreciation)
S&P 500 Index	1	358	3

The trust’s net assets transferred to the fund were $95,424,000, including net unrealized appreciation of $8,352,000.

About Your Fund’s Expenses

The expense discussion that follows is limited to the Structured Large-Cap Equity Fund, the only one of the Vanguard Structured Equity Funds that had six months of operating history as a mutual fund on March 31, 2007.

The table below 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.

Six Months Ended March 31, 2007¹
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
Structured Large-Cap Equity	9/30/2006	3/31/2007	Period²
Based on Actual Fund Return
Institutional Shares	$1,000.00	$1,077.03	$1.29
Institutional Plus Shares	1,000.00	1,077.77	0.78
Based on Hypothetical 5% Yearly Return
Institutional Shares	$1,000.00	$1,023.68	$1.26
Institutional Plus Shares	1,000.00	1,024.18	0.76

1	Results are shown only for portfolios that have operated as mutual funds for at least six months.

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 0.25% for Institutional Shares and 0.15% for 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.

Note that the expenses shown in the table are meant to highlight and help you compare ongoing costs only and do not reflect any transactional costs or account maintenance fees. Your fund does not charge transaction fees, such as purchase or redemption fees, nor does it carry a “sales load.”

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 funds’ investment advisor. 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 its most recent 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 the funds’ investment management since their inceptions, and took into account the organizational depth and stability of the advisor. Vanguard has been managing investments for more than two decades. George U. Sauter, Vanguard managing director and chief investment officer, has been in the investment management business since 1985 and has led the Quantitative Equity Group since 1987. James D. Troyer and James P. Stetler, the managers primarily responsible for the day-to-day management of the funds, have worked in investment management since 1979 and 1996, respectively. The Quantitative Equity Group adheres to a sound, disciplined investment management process; the team has considerable experience, stability, and depth.

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

Investment performance

The board considered the performance of the funds since their inceptions. The board noted that the funds have performed in line with expectations, and that their results have been consistent with their investment strategies. Information about the funds’ most recent performances can be found in the Performance Summary pages of this report.

Cost

The board concluded that the funds’ expense ratios were far below the average expense ratios charged by funds in their peer groups. The funds’ advisory expense ratios were also well below the peer-group averages. Information about the funds’ expense ratios appears in the About Your Fund’s Expenses section of this report as well as in the Financial Statements pages for each fund.

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

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