Chairmans Letter
Dear Shareholder,
Small was beautiful again in the first half of Vanguard Explorer Funds new fiscal year. As investors maintained a glass-half-full stance, the stocks of small and medium-sized companies held a sizable lead over their larger counterparts. Growth-oriented small-capitalization stocks, Explorers focus, were stronger still.
For the six months ended April 30, Explorer Fund returned almost 25%a strong absolute performance that nevertheless trailed (by about 2 percentage points) both its Russell 2500 Growth Index benchmark and the average return of its peer group. Compared with the benchmark index, the advisors notable success in health care was countered by missed opportunitiesespecially among consumer discretionary and technology stocks.
Please note: As we previously reported, AXA Rosenberg Investment Management was removed from the funds advisory team last August. On February 3, 2011, AXA Rosenberg announced that it had reached a settlement with the U.S. Securities and Exchange Commission related to a coding error in its quantitative investment process. Under the terms of the settlement, AXA Rosenberg compensated clients that were harmed by the coding error, including Vanguard Explorer Fund. (Please see Note H in Notes to Financial Statements.)

Strong returns around the globe
The headlines were dominated by political upheaval, natural and nuclear disaster, and economic distress, but global stock markets produced outstanding returns for the six months ended April 30. The broad U.S. stock market returned more than 17%. Although rising food and gasoline prices put pressure on consumer budgets, corporate earnings growth remained strong, and the pace of new job creation bounced back from extremely depressed levels.
For U.S.-based investors, international stock markets produced a smaller but still robust six-month return above 12% in U.S. dollars. Almost half of this return reflected exchange-rate gains produced largely by strength in the euro and currencies in emerging economies.
As the economy found its footing, rates edged higher
Rising longer-term interest rates put pressure on bond prices, which led to modest bond market returns for the six-month period. The broad taxable U.S. bond market returned about 0%. The broad municipal market returned 1.68%. The rise in rates reflected both confidence that the economic recovery would prove self-sustaining and thus nudge rates higher, and anxiety that higher rates would be necessary to provide some protection from inflation. Even so, inflation expectations

remained subdued, as measured by the difference between the yields of inflation-protected and nominal U.S. Treasury bonds.
The return on short-term money market instruments such as the 3-month U.S. Treasury bill remained near 0%, consistent with the Federal Reserve Boards target for short-term rates.
Classic growth prevailed, assisted by nuts and bolts
Vanguard Explorer Funds team of six investment advisory firms uses a variety of complementary investment strategies to identify high-quality, small and mid-sized companies that appear to have superior growth potential. Your advisors have tilled fertile ground since the U.S. stock market turnaround began in March 2009.
For the six months ended April 30, the funds holdings notched double-digit gains in nine of ten industry sectors, ranging from about 50% for energy to almost 17% for consumer discretionary stocks. The tiny utilities sector wasnt too far behind, at 9%.
Information technology, a home to many classic growth stocks, remained the funds largest sector by far. Strength was broad and deep: A wide variety of IT holdings participated in a resurgence in consumer spending and business investment as the economic recovery

proceeded. Buoyed by chip makerswhich have benefited from shorter replacement cycles for items such as computers and cell phonesand software companies, the tech sector was responsible for almost one-third of the funds total return.
Health care, the funds second-largest sector, was invigorated by the performance of biotech companies and service providers, including senior living facilities. And as the economy continued to grind into gear, industrialsespecially makers of machinery as well as electrical equipment and componentsprovided fortification. Together, health care and industrial holdings accounted for well more than one-third of the funds total return.
Even with robust results in major sectors, the fund fell short of its benchmark index. Some disappointments among consumer discretionary stocksnotably clothing retailers and gaming companiestrimmed more than 1 percentage point from the funds overall return. The funds IT sector also lagged that of the benchmark: Sizable stakes in top-ten holdings Alliance Data Systems and VeriFone Systems provided a boost, but couldnt make up for other misses. On the plus side, success in health care, notably biotech and health care providers, helped offset the slippage in tech stocks.

Spread your investments across multiple baskets
Equity returns for the six months were again impressivesmall-cap returns even more so. Of course, periods of strength are often followed by stretches of weakness, and market currents can change swiftly.
For example, as I write this letter, many investors are concerned about higher oil pricescould they derail the U.S. economic recovery, and what do they mean for inflation and short-term interest rates? After evaluating several scenarios, Vanguards economists concluded that benchmark U.S. crude oil prices would likely need to persist at $150 per barrel to generate another U.S. recession. And, despite higher prices for food and many commodities, slow growth in key inflation driverssuch as wages, money supply, and bank lendingsuggests that high inflation appears unlikely. Our economists views are available at vanguard.com.
One of the ways you can try to buffer your nest egg from such shocks is to develop allocations to stock, bond, and money market funds in proportions consistent with your goals and ability to withstand the stock markets unpredictable swings. Vanguard Explorer Fund can be
5
a useful, low-cost option in such a diversified portfolio. The funds multi-manager structure can help to dampen some of the volatility that often characterizes the performance of less-seasoned businesses, providing investors with a relatively more conservative source of exposure to those companies. Andeven though recent results have fallen short of the benchmark returnwe are confident that the funds carefully selected, experienced team of advisors has the potential to deliver superior results.
Thank you for entrusting your assets to Vanguard.
Sincerely,
F. William McNabb III

Advisors Report
For the six months ended April 30, 2011, Vanguard Explorer Fund returned almost 25% for both share classes. Your fund is managed by six independent advisors, a strategy that enhances the funds diversification by providing exposure to distinct, yet complementary, investment approaches. Its not uncommon for different advisors to have different views about individual securities or the broader investment environment.
The table following this report lists the advisors, the amount and percentage of fund assets each manages, and brief descriptions of their investment strategies. The advisors have provided the following assessment of the investment environment during the past six months and the notable successes and shortfalls in their portfolios. (Please note that the Granahan and Kalmar discussions refer to industry sectors as defined by Russell classifications, rather than by the Global Industry Classification Standard used elsewhere in this report.) These comments were prepared on May 11, 2011.
Wellington Management Company, LLP
Portfolio Manager:
Kenneth L. Abrams, Senior Vice President and Equity Portfolio Manager
Equities continued to rise as investors largely dismissed potentially unfavorable developments for economic growth, including rising commodity prices and inflation, unrest in the Middle East, the earthquake in Japan, and domestic budgetary deadlock at the federal level.
Strong corporate earnings and positive market sentiment outweighed concerns and continued to fuel gains for stocks.
Successes: Our portion of the fund benefited from strong security selection in the health care and telecommunication services sectors, with positive performance from holdings such as RehabCare and Vonage. The stock price of RehabCare, an operator of long-term care hospital and inpatient rehabilitation facilities, rose when the company agreed to be acquired by Kindred Healthcare. We subsequently exited the position. Vonage shares surged during the period, following its first positive subscriber growth in over two years. We continue to hold Vonage, which has an attractive growth outlook supported by market-share gains in international long distance, compelling new services for mobile users, and a growing base of customers outside the United States.
Shortfalls: Conversely, our stocks within the consumer discretionary and industrial sectors were the primary detractors for the period. For example, feature film company DreamWorks Animation declined following disappointing box office results at the release of its Megamind movie. We continue to hold DreamWorks because of its track record of producing strong content and monetizing its franchise through sequels, television specials, and live productions. U.S. Airways was also a detractor. Prior to the close of the period, we sold the position as higher fuel costs led us to reduce our exposure to airlines.

Granahan Investment Management, Inc.
Portfolio Manager:
Jack Granahan, CFA, Managing Partner
The stock market posted strong six-month results as it climbed a wall of worry that included rising instability in the Middle East, bank and sovereign debt issues in Europe, and rising oil and food prices in the United States as well as ongoing pressures in housing and unemployment. Instead, investors focused on the continued strength in corporate profits and increases in manufacturing. Energy stocks were particularly strong. The companies in our portfolio continued to generate strong sales and earnings growth, especially in producer durables, technology, and energy.
Successes: In terms of sectors, the portfolio benefited from strong relative performance in materials and financial services. Fronteer Gold, a gold exploration company, was acquired by Newmont Mining in our materials sector. Contributors in financial services included Waddell and Reed Financial, Cash America, and Factset Research Systems.
Individual stocks of note included Regeneron in health care, which was a strong contributor for the period on positive clinical results for its drug to treat macular degeneration. Strong stocks in technology included Verifone Systems, which provides point-of-sale electronic payment solutions; Acme Packet, a leading supplier of session border controllers for voice-over-internet communications; and Polycom, a supplier of videoconferencing systems.
Shortfalls: While we correctly underweighted the consumer discretionary sector, we held several significant detractors within the sector. One of these was WMS Gaming, a supplier of gaming products that also operates leased participation machines. Growth in casino purchases has flattened out, with recent earnings declining. We have retained our holding.
Individual detractors in other sectors included health care company Nektar, whose decision to solely handle the next phase of trials on a drug was seen as higher risk; we have retained our holding. In our technology sector, satellite imaging companies GeoEye and Digital Globe were penalized by concerns over government funding. We have added to our holdings of GeoEye.
Kalmar Investment Advisers
Portfolio Manager:
Ford B. Draper, Jr., President and Chief Investment Officer
Fears of a double-dip recession last summer prompted the Federal Reserve to implement a second round of quantitative easing, known as QE2. Since then, growing confidence in the sustainability of economic growth and rising corporate earnings have driven major stock market gains. This confirmed the bull market and allowed it to power past major geopolitical problems. Despite that, Kalmar continues to
8
emphasize better companies able to create their own future growth opportunities through innovation and internal initiatives. Meanwhile, stock market valuations still appear reasonable.
Successes: In a strongly rising market, all of our sector exposures contributed meaningfully to return, with our technology and producer durables holdings adding the most. Our biggest individual successes were: Cooper Cos., the international leader in specialty contact lenses; Alliance Data Systems, the provider of private label credit card, marketing, and loyalty services; Ariba, the leader in spend management software and systems; and Atmel, an improving semiconductor company with an important stake in touch screen technology.
Shortfalls: Our largest shortfalls came from: Acxiom, a business service information company that was hurt by an unexpected departure among its top management; Niko Resources, an offshore oil and gas explorer whose production temporarily slowed; and F5 Networks, a cloud computing networking company whose revenues slowed modestly.
Century Capital Management, LLC
Portfolio Manager:
Alexander L. Thorndike, Chief Investment Officer and Managing Partner
There remains a fragile confidence among investors that the U.S. economy can indeed sustain itself. The question still to be answered is whether private sector growth can assume a leadership role, as state and local governments grapple with budget deficits. We anticipate that corporate profit growth will remain healthy, though below the levels we experienced in 2010. We expect cost pressures to erode operating margins during the balance of 2011. Other areas of concern are the housing market, rising oil and gasoline prices, lingering issues over European debt, and an overheating of the Chinese economy.
Successes: Industrials was our best-performing sector for the period, led by Ladish and General Cable. Health care also contributed to performance, especially Brookdale Senior Living and Jazz Pharmaceuticals.
Shortfalls: Information technology and materials were our weakest-performing sectors for the period. HiSoft Technology International, Radware, and STR Holdings detracted from our performance.
Chartwell Investment Partners, L.P.
Portfolio Managers:
Edward N. Antoian, CFA, CPA, Managing Partner
John A. Heffern, Managing Partner and Senior Portfolio Manager
The global macroeconomic outlook, corporate revenue growth, and profit margins are key themes in the investment environment. They can separate winners from laggards, and we are alert to developing profit-margin pressures. Accordingly, our portfolio decisions reflect
9
our bias toward quality, leadership, defensible margins, and a pattern of successful execution.
Successes: Health care and industrials were our top-performing sectors. Strong stock selection in health services (Accretive Health) and medical specialties (Sirona Dental Systems) contributed to our results. Among industrial holdings, Baldor Electric, a manufacturer of electric motors, drives, and generators, was acquired at a 41% premium.
Shortfalls: Our holdings in IT services (NICE Systems), semiconductors (Marvell Technology Group), and computer peripherals (NetApp) underperformed for the period. Weakness in the energy sector was primarily driven by oil and gas producers (Rex Energy).
Vanguard Quantitative Equity Group
Portfolio Manager:
James D. Troyer, CFA, Principal
In the first half of this fiscal year, despite various global economic and geopolitical concerns, strong corporate earnings and better-than-expected job growth helped the U.S. equity markets to continue rising from the low point reached during the financial crisis two years ago.
While the overall performance of our portfolio is affected by the macro factors described above, it should be noted that our approach to investing focuses on a diversified mix of specific stock fundamentals. For the period, our stock selection model performed well, benefiting most from our quality signalwhich measures balance sheet strength and the sustainability of earningsas well as our market sentiment factor, which captures how investors reflect their opinions of a company through their activity in the market.
Successes: At the individual stock level, two of our best contributors were Sauer-Danfoss (+167%), and OPNET Technologies (+107%). When comparing the portfolios performance relative to its benchmark, we benefited from overweighting those two companies and from underweighting (for example, American Superconductor, 65%) or avoiding (for example, DreamWorks Animation, 25%) several poorly performing stocks.
Shortfalls: Unfortunately, we are not able to avoid all bad performers. Overweighted positions in iGATE (16%) and United Continental Holdings (21%) directly lowered performance. Also, underweighting companies that were not positively identified by the fundamentals in our model, such as Green Mountain Coffee Roasters (+103%) and Polycom (+77%), hurt overall results relative to our benchmark.

Notes to Financial Statements
Vanguard Explorer Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares: Investor Shares and Admiral Shares. Investor Shares are available to any investor who meets the funds minimum purchase requirements. Admiral Shares are designed for investors who meet certain administrative, service, and account-size criteria.
A. The following significant accounting policies conform to generally accepted accounting principles for U.S. mutual funds. The fund consistently follows such policies in preparing its financial statements.
1. Security Valuation: Securities are valued as of the close of trading on the New York Stock Exchange (generally 4 p.m., Eastern time) on the valuation date. Equity securities are valued at the latest quoted sales prices or official closing prices taken from the primary market in which each security trades; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Securities for which market quotations are not readily available, or whose values have been affected by events occurring before the funds 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 funds 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 funds 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. 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 funds 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.
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).
22
Explorer Fund
4. Repurchase Agreements: The fund invests in repurchase agreements. Securities pledged as collateral for repurchase agreements are held by a custodian bank until the agreements mature. Each agreement requires that the market value of the collateral be sufficient to cover payments of interest and principal; however, in the event of default or bankruptcy by the other party to the agreement, retention of the collateral may be subject to legal proceedings.
5. 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 funds tax positions taken for all open federal income tax years (October 31, 20072010), and for the period ended April 30, 2011, and has concluded that no provision for federal income tax is required in the funds financial statements.
6. Distributions: Distributions to shareholders are recorded on the ex-dividend date.
7. Security Lending: The fund may lend its securities to qualified institutional borrowers to earn additional income. Security loans are required to be secured at all times by collateral at least equal to the market value of securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability for the return of the collateral, during the period the securities are on loan. Security lending income represents fees charged to borrowers plus income earned on investing cash collateral, less expenses associated with the loan.
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. 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. Granahan Investment Management, Inc., Wellington Management Company, LLP, Kalmar Investment Advisers, Chartwell Investment Partners, L.P., and Century Capital Management, LLC, 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 fees of Granahan Investment Management, Inc., Kalmar Investment Advisers, Wellington Management Company, LLP and Chartwell Investment Partners, L.P are subject to quarterly adjustments based on performance for the preceding three years relative to the Russell 2500 Growth Index. The basic fee for Century Capital Management, LLC, is subject to quarterly adjustments based on performance since October 31, 2008, relative to a 50/50 blend of the Russell 2500 Index and Russell 2500 Growth Index.
The Vanguard Group provides investment advisory services to a portion of the fund on an at-cost basis; the fund paid Vanguard advisory fees of $315,000 for the six months ended April 30, 2011.
For the six months ended April 30, 2011, the aggregate investment advisory fee represented an effective annual basic rate of 0.20% of the funds average net assets, before an increase of $205,000 (0.00%) 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 April 30, 2011, the fund had contributed capital of $1,698,000 to Vanguard (included in Other Assets), representing 0.02% of the funds net assets and 0.68% of Vanguards capitalization. The funds trustees and officers are also directors and officers 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 funds management and administrative expenses. For the six months ended April 30, 2011, these arrangements reduced the funds expenses by $210,000 (an annual rate of 0.00% of average net assets).
E. Various inputs may be used to determine the value of the funds 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 1Quoted prices in active markets for identical securities.
Level 2Other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.).
Level 3Significant unobservable inputs (including the funds own assumptions used to determine the fair value of investments).
The following table summarizes the funds investments as of April 30, 2011, based on the inputs used to value them:
Level 1 | Level 2 | Level 3 | |
Investments | ($000) | ($000) | ($000) |
Common Stocks | 10,463,645 | 17,089 | |
Temporary Cash Investments | 448,809 | 30,747 | |
Futures ContractsAssets1 | 1,038 | | |
Total | 10,913,492 | 47,836 | |
1 Represents variation margin on the last day of the reporting period. |
F. At April 30, 2011, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:
($000) | ||||
Aggregate | ||||
Number of | Settlement | Unrealized | ||
Long (Short) | Value | Appreciation | ||

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

G. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes.
During the six months ended April 30, 2011, the fund realized net foreign currency losses of $65,000, which decreased distributable net income for tax purposes; accordingly, such losses have been reclassified from accumulated net realized losses to overdistributed net investment income.
During the six months ended April 30, 2011, the fund realized $40,256,000 of net capital gains resulting from in-kind redemptionsin which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized losses to paid-in capital.
The funds tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at October 31, 2010, the fund had available capital loss carryforwards totaling $1,533,525,000 to offset future net capital gains of $88,551,000 through October 31, 2016, and $1,444,974,000 through October 31, 2017. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending October 31, 2011; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balance above.
At April 30, 2011, the cost of investment securities for tax purposes was $8,131,245,000. Net unrealized appreciation of investment securities for tax purposes was $2,829,045,000, consisting of unrealized gains of $2,946,121,000 on securities that had risen in value since their purchase and $117,076,000 in unrealized losses on securities that had fallen in value since their purchase.
H. During the six months ended April 30, 2011, the fund purchased $4,625,085,000 of investment securities and sold $5,174,959,000 of investment securities, other than temporary cash investments. Realized net gains for the six months ended April 30, 2011, include $6,566,000 received from AXA Rosenberg Investment Management, a former investment advisor to the fund, as a result of a settlement with the Securities and Exchange Commission related to a coding error in its quantitative investment process. The settlement proceeds represent 0.06% of the funds average net assets for the six months ended April 30, 2011.

About Your Funds 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 funds gross income, directly reduce the investment return of the fund.
A funds 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 funds 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 funds 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 funds 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 casebecause the return used is not the funds actual returnthe 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 funds 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 funds 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 funds current prospectus.

Six Months Ended April 30, 2011 | |||
Beginning | Ending | Expenses | |
Account Value | Account Value | Paid During | |
Explorer Fund | 10/31/2010 | 4/30/2011 | Period |
Based on Actual Fund Return | |||
Investor Shares | $1,000.00 | $1,247.81 | $2.79 |
Admiral Shares | 1,000.00 | 1,248.85 | 1.90 |
Based on Hypothetical 5% Yearly Return | |||
Investor Shares | $1,000.00 | $1,022.32 | $2.51 |
Admiral Shares | 1,000.00 | 1,023.11 | 1.71 |
The calculations are based on expenses incurred in the most recent six-month period. The funds annualized six-month expense ratios for that period are 0.50% for Investor Shares and 0.34% 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.

Trustees Approve Advisory Arrangements
The board of trustees of Vanguard Explorer Fund renewed the funds investment advisory arrangements with Granahan Investment Management, Inc.; Kalmar Investment Advisers; The Vanguard Group, Inc. (through its Quantitative Equity Group); Chartwell Investment Partners, L.P.; and Century Capital Management, LLC, and approved amendments to the funds investment advisory agreement with Wellington Management Company, LLP, effective February 1, 2011. The amended agreement contains a new advisory fee schedule that increases the advisory fee paid to Wellington Management. The board determined at that time that the retention and amendment to the investment advisory agreement of the advisors was in the best interests of the fund and its shareholders.
The board based its decision upon an evaluation of each advisors investment staff, portfolio management process, and performance. The trustees considered the factors discussed below, among others. However, no single factor determined whether the board approved the arrangements. Rather, it was the totality of the circumstances that drove the boards decision.
Nature, extent, and quality of services
The board considered the quality of the funds investment management over both the short and long term, and took into account the organizational depth and stability of each advisor. The board noted the following:
Granahan Investment Management, Inc. Founded in 1985, Granahan specializes in small-cap growth equity investing. The firm uses fundamental research to select a portfolio of 125175 stocks with sustainable growth characteristics. The advisor achieves portfolio diversification through dedicated allocations to three categories of growth companies: core growth (40%70% of subportfolio assets), represented by companies with strong market position, based on proprietary products or services; pioneers (15%30%), companies with unique technology or innovations; and special value (15%30%), companies with growth potential overlooked by the market. The firm has managed a portion of the fund since 1990.
Wellington Management Company, LLP. Founded in 1928, Wellington Management is among the nations oldest and most respected institutional investment managers. Using a bottom-up, fundamentally driven approach, Wellington Management invests opportunistically in a diversified portfolio of high-quality stocks. The advisor attempts to identify companies that are early in their growth cycle. The research-intensive approach is supported by the teams deep and tenured analytical staff, which may also make use of Wellington Managements extensive industry research capabilities. The firm has advised the fund since 1967.
Kalmar Investment Advisers. Kalmar, together with its parent company, Kalmar Investments Inc., founded in 1982, specializes in small- and mid-cap growth equity investing. Kalmar is a research-driven investment firm that is entirely focused on the management of growth with value small- and mid-cap equity portfolios. Kalmar believes that there is a high-reward and low-risk anomaly offered by the equity market in the stocks of solid, well-managed, rapidly growing smaller companies. Through independent fundamental research, Kalmar attempts to discover such companies, buy them at undervalued levels, and own them for the longer term. The firm has managed a portion of the fund since 2005.
The Vanguard Group, Inc. Vanguard has been managing investments for more than three decades. The Quantitative Equity Group adheres to a sound, disciplined investment management process; the team has considerable experience, stability, and depth. Vanguard has managed a portion of the fund since 1997.
29
Chartwell Investment Partners, L.P. Chartwell is an independent, employee-owned firm, founded in 1997. The firm has expertise in small- and mid-cap equity management and employs a fundamental bottom-up strategy, seeking companies with superior growth potential trading at reasonable valuations. The firm has managed a portion of the fund since 1997.
Century Capital Management, LLC. Century Capital is a Boston-based investment management boutique, owned by the investment professionals within the firm. The public equity team, led by chief investment officer Alexander L. Thorndike, oversees two mutual funds: a small-cap growth fund and a large-cap fund. The team also oversees small-cap growth and small/mid-cap growth portfolios for institutional investors. Century Capital employs a fundamental, bottom-up investment approach that seeks to identify reasonably priced companies that will grow faster than the overall market. Independent research is a core tenet. The ideal investment is a well-managed company that is reasonably valued, in a non-capital-intensive business, with established products or services, a high return on equity, high recurring revenues, and improving margins. The firm has managed a portion of the fund since 2008.
The board concluded that each advisors experience, stability, depth, and performance, among other factors, warranted continuation of and amendment to (as applicable) the advisory arrangements.
Investment performance
The board considered the short- and long-term performance of the fund, including any periods of outperformance or underperformance of a relevant benchmark and peer group. The board concluded that each advisor has carried out the funds investment strategy in disciplined fashion, and that performance results have allowed the fund to remain competitive versus its benchmark and its peer group. Information about the funds most recent performance can be found in the Performance Summary section of this report.
Cost
The board concluded that the funds expense ratio was well below the average expense ratio charged by funds in its peer group and that the funds advisory fee rate was also well below the peer-group average. Information about the funds expenses appears in the About Your Funds Expenses section of this report as well as in the Financial Statements section, which also includes information about the advisory fee rate.
The board did not consider profitability of Granahan, Wellington Management, Kalmar, Chartwell, and Century Capital in determining whether to approve the advisory fees, because the firms are independent of Vanguard and the advisory fees are the result of arms-length negotiations. The board does not conduct a profitability analysis of Vanguard because of Vanguards unique at-cost structure. Unlike most other mutual fund management companies, Vanguard is owned by the funds it oversees, and produces profits only in the form of reduced expenses for fund shareholders.
The benefit of economies of scale
The board concluded that the funds shareholders benefit from economies of scale because of breakpoints in the advisory fee schedules for Granahan, Wellington Management, Kalmar, Chartwell, and Century Capital. The breakpoints reduce the effective rate of the fees as the funds assets managed by each firm increase.
The board also concluded that the funds low-cost arrangement with Vanguard ensures that the fund will realize economies of scale as it grows, with the cost to shareholders declining as the funds assets managed by Vanguard increase.
The board will consider whether to renew the advisory arrangements again after a one-year period.

Glossary
30-Day SEC Yield. A funds 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 funds security holdings in the previous 30 days are used to calculate the funds hypothetical net income for that period, which is then annualized and divided by the funds estimated average net assets over the calculation period. For the purposes of this calculation, a securitys income is based on its current market yield to maturity (in the case of bonds) or its projected dividend yield (for stocks). Because the SEC yield represents hypothetical annualized income, it will differat times significantlyfrom the funds actual experience. As a result, the funds income distributions may be higher or lower than implied by the SEC yield.
Beta. A measure of the magnitude of a funds 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 funds 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 funds investments in stocks and stock futures. Any holdings in short-term reserves are excluded.
Expense Ratio. The percentage of a funds 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 funds 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 funds stocks, weighted by the proportion of the funds assets invested in each stock. Stocks representing half of the funds 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.
31
Price/Earnings Ratio. The ratio of a stocks 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 companys future growth.
R-Squared. A measure of how much of a funds past returns can be explained by the returns from the market in general, as measured by a given index. If a funds total returns were precisely synchronized with an indexs returns, its R-squared would be 1.00. If the funds returns bore no relationship to the indexs 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 shareholders equity (net income divided by shareholders 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 funds 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 funds 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 Vanguards board members are independent, meaning that they have no affiliation with Vanguard or the funds they oversee, apart from the sizable personal investments they have made as private individuals. The independent board members have distinguished backgrounds in business, academia, and public service. Each of the trustees and executive officers oversees 179 Vanguard funds.
The following table provides information for each trustee and executive officer of the fund. More information about the trustees is in the Statement of Additional Information, which can be obtained, without charge, by contacting Vanguard at 800-662-7447, or online at vanguard.com.
