Vanguard’s Principles for Investing Success

We want to give you the best chance of investment success. These principles, grounded in Vanguard’s research and experience, can put you on the right path.

Goals. Create clear, appropriate investment goals.

Balance. Develop a suitable asset allocation using broadly diversified funds. Cost. Minimize cost.

Discipline. Maintain perspective and long-term discipline.

A single theme unites these principles: Focus on the things you can control. We believe there is no wiser course for any investor.

Please note: The opinions expressed in this report are just that—informed opinions. They should not be considered promises or advice. Also, please keep in mind that the information and opinions cover the period through the date on the front of this report. Of course, the risks of investing in your fund are spelled out in the prospectus.

See the Glossary for definitions of investment terms used in this report.

About the cover: Nautical images have been part of Vanguard’s rich heritage since its start in 1975. For an incoming ship, a lighthouse offers a beacon and safe path to shore. You can similarly depend on Vanguard to put you first––and light the way––as you strive to meet your financial goals. Our client focus and low costs, stemming from our unique ownership structure, assure that your interests are paramount.

Your Fund’s Performance at a Glance

• For the six months ended April 30, 2018, Vanguard Selected Value Fund returned –1.62%, behind the 2.55% return of its benchmark, the Russell Midcap Value Index, and the 2.65% average return of its mid-capitalization value fund peers.

• Value stocks trailed their growth counterparts for the period, while large- and small-cap stocks recorded generally similar returns.

• Each of the fund’s three advisors invests in the stocks of mid-cap companies they consider undervalued by the marketplace with solid prospects for recovery.

• Selected Value recorded negative returns in seven of the ten industry sectors it held investments in, and the fund trailed its benchmark counterparts in all ten sectors. Industrials, information technology, and health care detracted most from relative performance.

• Financials and energy contributed the most to the fund’s absolute returns, although the advisors’ stock holdings in those sectors weren’t advantageous.

The fund expense ratio shown is from the prospectus dated February 22, 2018, and represents estimated costs for the current fiscal year. For the six months ended April 30, 2018, the fund’s annualized expense ratio was 0.40%. The peer-group expense ratio is derived from data provided by Lipper, a Thomson Reuters Company, and captures information through year-end 2017.

CEO’s Perspective

Tim Buckley
President and Chief Executive Officer

Dear Shareholder,

I feel extremely fortunate to have the chance to lead a company filled with people who come to work every day passionate about Vanguard’s core purpose: to take a stand for all investors, to treat them fairly, and to give them the best chance for investment success.

When I joined Vanguard in 1991, I found a mission-driven team focused on improving lives—helping people retire more comfortably, put their children through college, and achieve financial security. I also found a company with purpose in an industry ripe for improvement.

It was clear, even early in my career, that the cards were stacked against most investors. Hidden fees, performance-chasing, and poor advice were relentlessly eroding investors’ dreams.

We knew Vanguard could be different and, as a result, could make a real difference. We have lowered the costs of investing for our shareholders significantly. And we’re proud of the performance of our funds.

Vanguard is built for Vanguard investors—we focus solely on you, our fund shareholders. Everything we do is designed to give our clients the best chance for investment success. In my role as CEO, I’ll keep this priority

2

front and center. We’re proud of what we’ve achieved, but we’re even more excited about what’s to come.

Steady, time-tested guidance

Our guidance for investors, as always, is to stay the course, tune out the hyperbolic headlines, and focus on your goals and what you can control, such as costs and how much you save. This time-tested advice has served our clients well over the decades.

Regardless of how the markets perform in the short term, I’m incredibly optimistic about the future for our investors. We have a dedicated team serving you, and we will never stop striving to make Vanguard the best place for you to invest through our high-quality funds and services, advice and guidance to help you meet your financial goals, and an experience that makes you feel good about entrusting us with your hard-earned savings.

Thank you for your continued loyalty.

Sincerely,

Mortimer J. Buckley
President and Chief Executive Officer

Advisors’ Report

For the six months ended April 30, 2018, Vanguard Selected Value Fund returned –1.62%. Your fund is managed by three independent advisors. This provides exposure to distinct yet complementary investment approaches, enhancing the fund’s diversification. It is not uncommon for different advisors to have different views about individual securities or the broader investment environment.

The advisors, the percentage and amount of fund assets each manages, and a brief description of their investment strategies are presented in the table below. The advisors have also prepared a discussion of the investment environment that existed during the fiscal period and of how portfolio positioning reflects this assessment. These comments were prepared on May 17, 2018.

Barrow, Hanley, Mewhinney & Strauss, LLC

Portfolio Managers:

James P. Barrow,
Executive Director

Mark Giambrone,
Managing Director

Over the six months, we saw a resumption of significant volatility created by uncertainties over geopolitics, interest rates, and economic growth. In periods like this, we still believe in focusing on longer-term

4

investment horizons and company fundamentals and try to take advantage of opportunities created by the volatility.

To this end, we still believe we are in a period of positive economic growth, modestly rising rates, and occasional political uncertainties. Therefore, we remain positioned to benefit from this outlook. It has led us to underweight areas of the market that tend to be more defensive but that should not hold up in a rising-rate environment with already stretched valuations. These areas are real estate, utilities, consumer staples, and telecommunication services, sometimes referred to as “the rust stocks.” This does lead us to be overweight in areas that will benefit from this environment, such as financials, consumer discretionary, materials, information technology, and industrials.

Markets appear to be priced for robust earnings growth, continued high profit margins, and the expected enactment of pro-growth policies. We believe that we are positioned appropriately to take advantage of value in the market and that we are past the point of maximum uncertainty, and we expect our performance to continue to recover and benefit from such an environment.

Furthermore, we believe that the most recent environment––a highly correlated, macro-driven bull market now in its eighth year––is turning in favor of differentiated stock selection and that our active management will reap the benefits.

Pzena Investment Management, LLC

Portfolio Managers:

Richard Pzena, Managing Principal and Co-Chief Investment Officer John Flynn, Principal Ben Silver, CFA, CPA, Principal

U.S. equity markets continued their long bull market advance, though volatility in the period’s second half caused by rising interest rates and rumblings of a trade war muted the strong returns of the first half. Positions in financials and consumer discretionary drove our portion of the fund.

Financial holdings benefited from improving economic growth, the new tax law, and deregulation. This sector also showed strength across industries––as with Voya Financial, a life insurer; Regions Financial and Comerica, both regional banks; and Axis Capital, a property and casualty insurer. HPE, the server and networking products business spun out of Hewlett Packard, advanced amid strong earnings, robust sales growth, improved expectations, and plans to return $7 billion to shareholders over the next two years.

The main detractors were JELD-WEN (windows and doors) and Terex (cranes). JELD-WEN’s weakness derived from concerns over labor inflation and housing affordability in light of lower tax incentives and higher interest rates. Terex fell, along with the entire machinery industry, amid fears of margin pressure and greater competitive threats because of potential

5

steel tariffs imposed by the administration. We view the problems as temporary and continue to believe in the company’s value proposition.

A broadening opportunity set led us to trim holdings in financials and information technology, allowing us to add several new holdings in consumer discretionary, health care, and industrials. Two examples are MEDNAX and Carlisle Companies. Despite a long history of stable margins, MEDNAX—the leading provider of neonatal physician services—has seen earnings drop recently because of a lower number of births, an adverse payer mix, and cyclical wage inflation; we expect these factors to be offset by management actions and normalization in births.

Carlisle is an industrial conglomerate with strong positions in commercial roofing, aerospace components, and other businesses. Higher input costs and a challenging technology transition for in-flight entertainment systems have pressured earnings. The company is well-positioned to navigate these challenges and return to normal profitability. We sold our holdings in Lamar Advertising, Hilton Worldwide, and Validus Holdings (which was bought by AIG) as they approached fair value.

In a market that appears expensive, the spread in valuations between the cheapest and costliest stocks is among the widest in 50 years, leaving a broad set of opportunities for the portfolio. We are finding the best ones in financials, industrials, IT, and more recently health care.

Donald Smith & Co., Inc.

Portfolio Managers: Donald G. Smith, President and Chief Investment Officer

Richard L. Greenberg, CFA, Senior Portfolio Manager and Director of Research

The portfolio at the end of April continues to meet our criteria of owning a concentrated set of low price-to-tangible book value stocks with attractive long-term earnings potential. The portfolio currently sells at 113% of tangible book value and 8.2 times our estimate of “normalized” earnings. In contrast, the S&P 500 Index sells at 961% of tangible book value and 15.8 times normalized earnings.

Energy and information technology holdings were the top contributors, while financials and precious metals holdings were mixed. Homebuilders and airline/aircraft leasing companies largely detracted from performance. The biggest contributor was Micron Technology—also the largest holding in the portfolio—as it continued the appreciation it experienced in 2017 on good earnings and solid guidance amid strong memory-product prices.

WPX Energy was up more recently, catching up to the rise in oil prices that has taken place since mid-2017. XL Group rose significantly on the news that AXA had agreed to acquire it at $57.60 per share to create “the number one global property and casualty commercial lines insurer.” This also lifted the property and casualty insurance group more broadly and benefited Axis Capital.

6

Offsetting this was Air France, which has struggled with a union strike over pay. But even amid that uncertainty, Air France-KLM is still solidly profitable, and the recent resignation of the airline’s CEO may be a catalyst for both sides to eventually reach agreement. Insurance company Unum Group declined amid market worries about its exposure to long-term care liabilities. Aircraft leasing company AerCap also declined slightly, but we continue to like its capital deployment approach (that is, share buybacks), and air traffic remains strong.

We added to our holdings in Air France-KLM, Aspen Insurance, Axis Capital, IAMGOLD, and Taylor Morrison, while trimming our exposure in CNA Financial, JetBlue, Kinross Gold, Micron, Toll Brothers, Unum Group, WPX Energy, and XL Group. We sold out of our holdings in News Corp.

We initiated two new positions: Gold Fields and Sanmina. Gold Fields is a substantial gold producer that trades at a discount because of market concerns about its historically troubled South Deep mine in South Africa, but the company’s valuation is compelling even ignoring this mine, which can be viewed as a “free option.” Sanmina, an electronics manufacturing services supplier, differentiates itself with a low-volume/high-mix, high-value-added strategy; a vertically integrated model; and a high-margin components business.

Our largest industry weightings are airlines and aircraft leasing, precious metals, insurance, and technology.

Results of Proxy Voting

At a special meeting of shareholders on November 15, 2017, fund shareholders approved the following proposals:

Proposal 1—Elect trustees for the fund.*

The individuals listed in the table below were elected as trustees for the fund. All trustees with the exception of Ms. Mulligan, Ms. Raskin, and Mr. Buckley (each of whom already serves as a director of The Vanguard Group, Inc.) served as trustees to the funds prior to the shareholder meeting.

Proposal 3—Approve a manager-of-managers arrangement with wholly owned subsidiaries of Vanguard.

This arrangement enables Vanguard or the fund to enter into and materially amend investment advisory arrangements with wholly owned subsidiaries of Vanguard, subject to the approval of the fund’s board of trustees and any conditions imposed by the Securities and Exchange Commission (SEC), while avoiding the costs and delays associated with obtaining future shareholder approval. The ability of the fund to operate in this manner is contingent upon the SEC’s approval of a pending application for an order of exemption.

8

Sector categories are based on the Global Industry Classification Standard (“GICS”), except for the “Other” category (if applicable), which includes securities that have not been provided a GICS classification as of the effective reporting period.

These measures show the degree and timing of the fund’s fluctuations compared with the indexes over 36 months.

The holdings listed exclude any temporary cash investments and equity index products.

1 The expense ratio shown is from the prospectus dated February 22, 2018, and represents estimated costs for the current fiscal year. For the six months ended April 30, 2018, the annualized expense ratio was 0.40%.

Selected Value Fund

Notes to Financial Statements

Vanguard Selected Value Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund.

A. The following significant accounting policies conform to generally accepted accounting principles for U.S. investment companies. 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 affected by events occurring before the fund’s pricing time but after the close of the securities’ primary markets, are valued at their fair values calculated according to procedures adopted by the board of trustees. These procedures include obtaining quotations from an independent pricing service, monitoring news to identify significant market- or security-specific events, and evaluating changes in the values of foreign market proxies (for example, ADRs, futures contracts, or exchange-traded funds), between the time the foreign markets close and the fund’s pricing time. When fair-value pricing is employed, the prices of securities used by a fund to calculate its net asset value may differ from quoted or published prices for the same securities. Investments in Vanguard Market Liquidity Fund are valued at that fund’s net asset value. Temporary cash investments 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.

2. Foreign Currency: Securities and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars using exchange rates obtained from an independent third party as of the fund’s pricing time on the valuation date. Realized gains (losses) and unrealized appreciation (depreciation) on investment securities include the effects of changes in exchange rates since the securities were purchased, combined with the effects of changes in security prices. Fluctuations in the value of other assets and liabilities resulting from changes in exchange rates are recorded as unrealized foreign currency gains (losses) until the assets or liabilities are settled in cash, at which time they are recorded as realized foreign currency gains (losses).

3. 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. Counterparty risk involving futures is mitigated because a regulated clearinghouse is the counterparty instead of the clearing broker. To further mitigate counterparty risk, the fund trades futures contracts on an exchange, monitors the financial strength of its clearing brokers and clearinghouse, and has entered into clearing agreements with its clearing brokers. The clearinghouse imposes initial margin requirements to secure the fund’s performance and requires daily settlement of variation margin representing changes in the market value of each contract.

18

Selected Value Fund

Futures contracts are valued at their quoted daily settlement prices. The notional 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 Assets and Liabilities 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).

During the six months ended April 30, 2018, the fund’s average investments in long and short futures contracts represented 2% and 0% of net assets, respectively, based on the average of the notional amounts at each quarter-end during the period.

4. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Management has analyzed the fund’s tax positions taken for all open federal income tax years (October 31, 2014–2017), and for the period ended April 30, 2018, and has concluded that no provision for federal income tax is required in the fund’s financial statements.

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

6. Securities Lending: To earn additional income, the fund lends its securities to qualified institutional borrowers. Security loans are subject to termination by the fund at any time, and are required to be secured at all times by collateral in an amount at least equal to the market value of securities loaned. Daily market fluctuations could cause the value of loaned securities to be more or less than the value of the collateral received. When this occurs, the collateral is adjusted and settled before the opening of the market on the next business day. The fund further mitigates its counterparty risk by entering into securities lending transactions only with a diverse group of prequalified counterparties, monitoring their financial strength, and entering into master securities lending agreements with its counterparties. The master securities lending agreements provide that, in the event of a counterparty’s default (including bankruptcy), the fund may terminate any loans with that borrower, determine the net amount owed, and sell or retain the collateral up to the net amount owed to the fund; however, such actions may be subject to legal proceedings. While collateral mitigates counterparty risk, in the event of a default, the fund may experience delays and costs in recovering the securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability in the Statement of Assets and Liabilities for the return of the collateral, during the period the securities are on loan. Securities lending income represents fees charged to borrowers plus income earned on invested cash collateral, less expenses associated with the loan. During the term of the loan, the fund is entitled to all distributions made on or in respect of the loaned securities.

7. Credit Facility: The fund and certain other funds managed by The Vanguard Group (“Vanguard”) participate in a $3.1 billion committed credit facility provided by a syndicate of lenders pursuant to a credit agreement that may be renewed annually; each fund is individually liable for its borrowings, if any, under the credit facility. Borrowings may be utilized for temporary and emergency purposes, and are subject to the fund’s regulatory and contractual borrowing restrictions. The participating funds are charged administrative fees and an annual commitment fee of 0.10% of the undrawn amount of the facility; these fees are allocated to the funds based on a method approved by the fund’s board of trustees and included in Management and Administrative expenses on the fund’s Statement of Operations. Any borrowings under this facility bear interest at a rate based upon the higher of the one-month London Interbank Offered Rate, federal funds effective rate, or overnight bank funding rate plus an agreed-upon spread.

The fund had no borrowings outstanding at April 30, 2018, or at any time during the period then ended.

19

Selected Value Fund

8. 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. Premiums and discounts on debt securities purchased are amortized and accreted, respectively, to interest income over the lives of the respective securities. 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.

B. The investment advisory firms Barrow, Hanley, Mewhinney & Strauss, LLC, Pzena Investment Management, LLC, and Donald Smith & Co., Inc., each provide investment advisory services to a portion of the fund for a fee calculated at an annual percentage rate of average net assets managed by the advisor. The basic fee of Barrow, Hanley, Mewhinney & Strauss, LLC, and Pzena Investment Management, LLC, are subject to quarterly adjustments based on performance relative to the Russell Midcap Value Index for the preceding three years. The basic fee of Donald Smith & Co., Inc., is subject to quarterly adjustments based on performance relative to the MSCI Investable Market 2500 Index for the preceding five years.

Vanguard manages the cash reserves of the fund as described below.

For the six months ended April 30, 2018, the aggregate investment advisory fee represented an effective annual basic rate of 0.22% of the fund’s average net assets, before a net increase of $534,000 (0.01%) based on performance.

C. In accordance with the terms of a Funds’ Service Agreement (the “FSA”) between Vanguard and the fund, Vanguard furnishes to the fund corporate management, administrative, marketing, distribution, and cash management services at Vanguard’s cost of operations (as defined by the FSA). These costs of operations are allocated to the fund based on methods and guidelines approved by the board of trustees. Vanguard does not require reimbursement in the current period for certain costs of operations (such as deferred compensation/benefits and risk/insurance costs); the fund’s liability for these costs of operations is included in Payables to Vanguard on the Statement of Assets and Liabilities. All other costs of operations payable to Vanguard are generally settled twice a month.

Upon the request of Vanguard, the fund may invest up to 0.40% of its net assets as capital in Vanguard. At April 30, 2018, the fund had contributed to Vanguard capital in the amount of $566,000, representing 0.01% of the fund’s net assets and 0.23% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and employees, respectively, of Vanguard.

D. The fund has asked its investment advisors 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 April 30, 2018, these arrangements reduced the fund’s management and administrative expenses by $72,000 and custodian fees by $12,000. The total expense reduction represented an effective annual rate of 0.00% of the fund’s average net assets.

Selected Value Fund

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

Level 1—Quoted prices in active markets for identical securities.

Level 2—Other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.).

Level 3—Significant unobservable inputs (including the fund’s own assumptions used to determine the fair value of investments). Any investments valued with significant unobservable inputs are noted on the Statement of Net Assets.

The following table summarizes the market value of the fund’s investments as of April 30, 2018, based on the inputs used to value them:

F. 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 April 30, 2018, the cost of investment securities for tax purposes was $8,387,311,000. Net unrealized appreciation of investment securities for tax purposes was $2,145,778,000, consisting of unrealized gains of $2,742,874,000 on securities that had risen in value since their purchase and $597,096,000 in unrealized losses on securities that had fallen in value since their purchase.

G. During the six months ended April 30, 2018, the fund purchased $1,857,118,000 of investment securities and sold $1,617,674,000 of investment securities, other than temporary cash investments.

21

I. Certain of the fund’s investments are in companies that are considered to be affiliated companies of the fund because the fund owns more than 5% of the outstanding voting securities of the company or the issuer is another member of The Vanguard Group. Transactions during the period in securities of these companies were as follows:

1 Not applicable—at October 31, 2017, the issuer was not an affiliated company of the fund. 2 Not applicable—purchases and sales are for temporary cash investment purposes.

J. Management has determined that no material events or transactions occurred subsequent to April 30, 2018, that would require recognition or disclosure in these 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 accompanying table illustrates your fund’s costs in two ways:

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

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

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

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

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

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

The calculations are based on expenses incurred in the most recent six-month period. The fund’s annualized six-month expense ratio for that period is 0.40%. 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 (181/365).

Trustees Approve Advisory Arrangements

The board of trustees of Vanguard Selected Value Fund has renewed the fund’s investment advisory arrangements with Barrow, Hanley, Mewhinney & Strauss, LLC (Barrow Hanley), Donald Smith & Co., Inc. (Donald Smith & Co.), and Pzena Investment Management, LLC (Pzena). The board determined that renewing the advisory arrangements was in the best interests of the fund and its shareholders.

The board based its decision upon an evaluation of each advisor’s investment staff, portfolio management process, and performance. This evaluation included information provided to the board by Vanguard’s Portfolio Review Department, which is responsible for fund and advisor oversight and product management. The Portfolio Review Department met regularly with the advisors and made monthly presentations to the board during the fiscal year that directed the board’s focus to relevant information and topics.

The board, or an investment committee made up of board members, also received information throughout the year during advisor presentations. For each advisor presentation, the board was provided with letters and reports that included information about, among other things, the advisory firm and the advisor’s assessment of the investment environment, portfolio performance, and portfolio characteristics.

In addition, the board received monthly reports, which included a Market and Economic Report, a Fund Dashboard Monthly Summary, and a Fund Performance Report.

Prior to their meeting, the trustees were provided with a memo and materials that summarized the information they received over the course of the year. They also considered the factors discussed below, among others. However, no single factor determined whether the board approved the arrangements. Rather, it was the totality of the circumstances that drove the board’s decision.

Nature, extent, and quality of services

The board reviewed the quality of the fund’s investment management services over both the short and long term, and took into account the organizational depth and stability of each advisor. The board considered the following:

Barrow Hanley. Founded in 1979, Barrow Hanley is known for its commitment to value investing. A subsidiary of Old Mutual Asset Managers, Barrow Hanley remains independently managed. Using fundamental research, Barrow Hanley seeks to make long-term investments in quality or improving businesses that are undervalued because of short-term disappointments. The advisor seeks to construct a portfolio with strict adherence to valuation factors, with below-average price/ earnings and price/book value ratios, and above-average current yields. Barrow Hanley has advised the fund since its inception in 1996.

Donald Smith & Co. Founded in 1983, Donald Smith & Co. is a deep-value-oriented firm that manages large-, mid-, and small-capitalization value portfolios. Donald Smith & Co. employs a strictly bottom-up approach, focusing on companies in the bottom decile of price-to-tangible-book value in the benchmark. The advisor uses fundamental analysis to invest in those companies that it considers to be inexpensive relative to their estimate of normalized earnings power and to have solid balance sheets and asset quality. Donald Smith & Co. has managed a portion of the fund since 2005.

25

Pzena. Founded in 1995, Pzena is a global investment management firm that employs a deep value investment approach. Pzena uses in-depth fundamental research to identify companies that are temporarily underperforming their long-term earnings power. Companies are purchased when Pzena judges that: (1) the company’s problems are temporary; (2) management has a viable strategy to generate recovery; and (3) there is meaningful downside protection in case the earnings recovery does not materialize. Pzena has managed a portion of the fund since 2014.

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

Investment performance

The board considered the short- and long-term performance of the fund and each advisor, including any periods of outperformance or underperformance compared with a relevant benchmark index and peer group. The board concluded that the performance was such that the advisory arrangements should continue. Information about the fund’s most recent performance can be found in the Performance Summary section of this report.

Cost

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

The board did not consider the profitability of Barrow Hanley, Donald Smith & Co., or Pzena in determining whether to approve the advisory fees, because the firms are independent of Vanguard and the advisory fees are the result of arm’s-length negotiations.

The benefit of economies of scale

The board concluded that the fund’s shareholders benefit from economies of scale because of breakpoints in the advisory fee schedules for Barrow Hanley, Donald Smith & Co., and Pzena. The breakpoints reduce the effective rate of the fees as the fund’s assets managed by each advisor increase.

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

Glossary

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

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

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

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

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

Expense Ratio. A fund’s total annual operating expenses expressed as a percentage of the fund’s average net assets. The expense ratio includes management and administrative expenses, but does not include the transaction costs of buying and selling portfolio securities.

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

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

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

Price/Book Ratio. The share price of a stock divided by its net worth, or book value, per share.

For a fund, the weighted average price/book ratio of the stocks it holds.

27

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

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

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

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

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

The People Who Govern Your Fund

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

A majority of Vanguard’s board members are independent, meaning that they have no affiliation with Vanguard or the funds they oversee, apart from the sizable personal investments they have made as private individuals. The independent board members have distinguished backgrounds in business, academia, and public service. Each of the trustees and executive officers oversees 208 Vanguard funds.

Information for each trustee and executive officer of the fund appears below. The mailing address of the trustees and officers is P.O. Box 876, Valley Forge, PA 19482.

Your Fund’s Performance at a Glance

• Stocks advanced as the period opened, supported by improving economic data, solid corporate earnings, and new tax reform legislation. But as the half year progressed, investors’ inflation fears increased, causing stocks to decline.

• Value stocks trailed their growth counterparts, while large-cap stocks outpaced their small-cap peers.

• The industrial, health care, and energy sectors helped drive relative performance.

• Consumer staples and consumer discretionary stocks were among the biggest detractors from relative performance.

The fund expense ratio shown is from the prospectus dated February 22, 2018, and represents estimated costs for the current fiscal year.

CEO’s Perspective

Tim Buckley
President and Chief Executive Officer

Dear Shareholder,

I feel extremely fortunate to have the chance to lead a company filled with people who come to work every day passionate about Vanguard’s core purpose: to take a stand for all investors, to treat them fairly, and to give them the best chance for investment success.

When I joined Vanguard in 1991, I found a mission-driven team focused on improving lives—helping people retire more comfortably, put their children through college, and achieve financial security. I also found a company with purpose in an industry ripe for improvement.

It was clear, even early in my career, that the cards were stacked against most investors. Hidden fees, performance-chasing, and poor advice were relentlessly eroding investors’ dreams.

We knew Vanguard could be different and, as a result, could make a real difference. We have lowered the costs of investing for our shareholders significantly. And we’re proud of the performance of our funds.

Vanguard is built for Vanguard investors—we focus solely on you, our fund shareholders. Everything we do is designed to give our clients the best chance for investment success. In my role as CEO, I’ll keep this priority

2

front and center. We’re proud of what we’ve achieved, but we’re even more excited about what’s to come.

Steady, time-tested guidance

Our guidance for investors, as always, is to stay the course, tune out the hyperbolic headlines, and focus on your goals and what you can control, such as costs and how much you save. This time-tested advice has served our clients well over the decades.

Regardless of how the markets perform in the short term, I’m incredibly optimistic about the future for our investors. We have a dedicated team serving you, and we will never stop striving to make

Vanguard the best place for you to invest through our high-quality funds and services, advice and guidance to help you meet your financial goals, and an experience that makes you feel good about entrusting us with your hard-earned savings.

Thank you for your continued loyalty.

Sincerely,

Mortimer J. Buckley
President and Chief Executive Officer

Advisors’ Report

For the six months ended April 30, 2018, Vanguard Mid-Cap Growth Fund returned 7.58%. It outpaced its benchmark, the Russell Midcap Growth Index, and the average return of its mid-capitalization growth peer funds.

Your fund is managed by two independent advisors, a strategy that enhances the fund’s diversification by providing exposure to distinct yet complementary investment approaches. It’s not uncommon for different advisors to have different views about individual securities or the broader investment environment.

The fund’s advisors, the percentage of fund assets each manages, and brief descriptions of their investment strategies are presented in the table that follows. The advisors have also prepared a discussion of the investment environment that existed during the six-month period and of how their portfolio positioning reflects this assessment. These comments were prepared on May 11, 2018.

U.S. equity markets were positive but mixed for the half year ended April 30, 2018. Mid-cap growth stocks, as measured by the Russell Midcap Growth Index, outperformed value-oriented mid-caps, as measured by the Russell Midcap Value Index. Underlying fundamentals were strong. Earnings were higher than expected for all styles and market caps, driven by strong economic growth, the largest corporate tax cuts in decades, and solid execution.

However, the six-month time frame was really a tale of two very different periods. The Russell Midcap Growth Index returned almost 10% for the three months ended January 31. An uptick in volatility arrived in February, driven in part by increased expectations for interest rate hikes under new Federal Reserve Chairman Jerome Powell. Other factors included uncertainty surrounding trade policy following the threat of tariffs and the potential for a trade war with China.

Markets also grew concerned about the possibility of increased regulation for some of the largest technology companies after it emerged that they may have been

collecting more user data than previously thought. This resulted in negative performance for the Russell Midcap Growth Index for the three months ended April 30.

Sector returns for our portion of the portfolio were mixed. Stock selection in information technology, consumer staples, consumer discretionary, and real estate weighed on returns. But selection in health care, industrials, materials, energy, and financials was positive.

The underperformance in information technology was led by software and services holding Euronet Worldwide. Euronet provides electronic payment and transaction processing solutions for financial institutions, retailers, service providers, and individual consumers.

We purchased the stock because of the high barriers to entry in each of the company’s three core segments (ATM, ePay, and money transfer), its strong management team, and the opportunity it had to expand its profit margins through expense management. It declined following concerns that the European Union would effectively cap ATM charges for customers traveling abroad. Although this would affect the company’s future earnings, we felt the reaction was overblown based on the likely timeline of the regulation’s implementation (2023) and the relative size of the business. As a result, we continue to hold Euronet.

5

Health care was the top-performing sector, led by pharmaceutical and biotechnology stocks and life-sciences holding bluebird bio. Bluebird has focused on developing gene therapies that target “orphan diseases,” conditions that affect small, underserved but high-need populations. The company’s technology uses an HIV-1 virus, lentivirus, to modify genes and correct a patient’s abnormal stem cells. These cells are then reintroduced into a patient’s bone marrow via transplant, where they produce properly functioning daughter cells to correct the disorder. In late 2017, bluebird bio shared strong results for its ongoing Phase 1 therapy study in late-stage, relapsed multiple myeloma. We believe the company is in the early stages of its potential, and we continue to hold the position.

William Blair Investment Management, LLC

Portfolio Managers: Robert C. Lanphier, Partner David Ricci, CFA, Partner Dan Crowe, CFA, Partner

The equity market as measured by the Russell Midcap Growth Index advanced from November to January, supported by improving economic data and solid corporate earnings growth. Further bolstering investor optimism was the reduction of the U.S. corporate statutory tax rate in December.

However, the market weakened and volatility spiked after inflationary fears arose in late January as the future ramifications of a tight labor market weighed on investors’ minds. Companies generally reported strong financial results and economic data was mostly positive for the first half of the period, but the Russell Midcap Growth Index posted declines from February to April.

Our performance was driven by a combination of strong stock selection and our investment style. After trailing modestly in the first half of the period, our strategy added significant value beginning in February when the market turned negative. As investors digested the inflation-related cost pressures on businesses, our higher and more sustainable growth bias, which leads us to companies with value-added products and services and flexible pricing, was helpful.

Stock selection was strong in most sectors. The top contributors were industrials, including Copart and Verisk Analytics; health care, including ABIOMED; and information technology, including Red Hat. The best performer was Copart, an auction platform for salvage vehicles. It benefited from higher volumes of newer and more expensive cars as insurers chose to scrap vehicles sooner because of the rising cost of repairs. This was a key component of our investment thesis.

6

Shares of Red Hat, an open-source software provider, advanced on strong demand for Red Hat Linux and the company’s cloud-based solutions. We believe the firm will continue to benefit from the massive shift in enterprise IT architectures to Linux-based operating systems, for which it provides support, services, and other products.

Domino’s Pizza was also among the period’s standouts, but in aggregate, stock selection in the consumer discretionary sector detracted from results. Notable laggards included Newell Brands, CarMax, and Mohawk Industries.

Newell Brands, a diversified consumer and commercial products company, underperformed in part because of a challenging retail environment. Its 2016 acquisition of Jarden also proved to be more complex than anticipated. Other large detractors included Ball and Coherent.

Ball provides metal packaging for beverages, foods, and household products. Its share price weakness was primarily due to a drop in North American beverage can sales in late 2017 as hurricanes resulted in lost production.

Looking forward, we continue to focus on identifying quality growth businesses at attractive valuations. The economic recovery following the global financial crisis began almost nine years ago, and we are entering a period of unprecedented late-cycle fiscal stimulus. Although the effect of this stimulus remains to be seen, we believe it is in our clients’ best interest for us to concentrate on bottom-up, fundamental analysis. We believe purchasing companies with durable growth drivers that are underappreciated by other investors will allow us to outperform in a variety of economic scenarios and over the long term.

Results of Proxy Voting

At a special meeting of shareholders on November 15, 2017, fund shareholders approved the following proposals:

Proposal 1—Elect trustees for the fund.*

The individuals listed in the table below were elected as trustees for the fund. All trustees with the exception of Ms. Mulligan, Ms. Raskin, and Mr. Buckley (each of whom already serves as a director of The Vanguard Group, Inc.) served as trustees to the funds prior to the shareholder meeting.

Proposal 3—Approve a manager-of-managers arrangement with wholly owned subsidiaries of Vanguard.

This arrangement enables Vanguard or the fund to enter into and materially amend investment advisory arrangements with wholly owned subsidiaries of Vanguard, subject to the approval of the fund’s board of trustees and any conditions imposed by the Securities and Exchange Commission (SEC), while avoiding the costs and delays associated with obtaining future shareholder approval. The ability of the fund to operate in this manner is contingent upon the SEC’s approval of a pending application for an order of exemption.
