Stock Index Fund

A LETTER FROM THE CHAIRMAN AND CEO

Dear Shareholder:

We are pleased to present this semiannual report for Dreyfus International Stock Index Fund covering the six-month period from November 1, 2009, through April 30, 2010.

Psychology plays a very important role in how investors — especially retail investors — perceive the markets and make asset allocation decisions. Unlike in an ideal world populated by the purely rational investor who would seek out investments that deliver the best risk/ return characteristics, the everyday investor is generally influenced by emotions. Currently, investor emotions appear to be deeply divided, with a large amount of investors still seeking low risk investments (such as cash instruments) and others seeking high risk investments (such as smaller-cap and emerging market securities), while the investment classes in the middle of the risk spectrum have seemingly been ignored.

It is important to note that the investor sentiment cycle usually lags the economic cycle.That’s why we continue to stress the importance of a long-term, well-balanced asset allocation strategy that can help cushion the volatility produced by the emotional swings of the financial markets. If you have not revisited your investment portfolio in the past year, we urge you to speak with your financial advisor about positioning your portfolio to take advantage of long-term market fundamentals rather than lie susceptible to short-term emotions.

For information about how the fund performed during the reporting period, as well as general market perspectives, we have provided a Discussion of Fund Performance.

Thank you for your continued confidence and support.

Jonathan R. Baum
Chairman and Chief Executive Officer
The Dreyfus Corporation

DISCUSSION OF FUND PERFORMANCE

For the period of November 1, 2009, through April 30, 2010, as provided by Karen Q.Wong and Richard A. Brown, Portfolio Managers

Fund and Market Performance Overview

For the six-month period ended April 30, 2010, Dreyfus International Stock Index Fund produced a total return of 2.36%.¹This compares with a 2.48% total return for the fund’s benchmark, the Morgan Stanley Capital International Europe, Australasia, Far East Index (the “MSCI EAFE Index” or the “Index”), during the same period.²

International stock markets encountered heightened volatility during the reporting period, as the worldwide economy gradually recovered but Europe suffered through a sovereign debt crisis.As a result, international stocks produced disparate results from one region of the world to another.The difference in returns between the fund and the Index was primarily the result of transaction costs and operating expenses that are not reflected in the Index’s return.

The Fund’s Investment Approach

The fund seeks to match the performance of the MSCI EAFE Index, a broadly diversified,international index composed of approximately 1,000 companies located in developed markets outside the United States and Canada.The fund attempts to match the Index’s return before fees and expenses by aligning the portfolio composition with the composition of the MSCI EAFE Index.The fund also invests in securities that represent the market as a whole, such as stock index futures, and manages its exposure to foreign currencies so that the fund’s currency profile matches the currency makeup of the MSCI EAFE Index.

Economic Recovery, Debt Crisis Sparked Volatility

Although unemployment has remained stubbornly high and credit availability has been relatively tight in many regions of the world, improved manufacturing activity and robust demand for energy and industrial commodities, particularly from the emerging markets, gener-

ally helped boost confidence among businesses,consumers and investors. However, market conditions differed significantly from one region to another.While the emerging markets of Asia and Latin America seemed to thrive, Europe was mired in a sovereign debt crisis.The United States showed encouraging signs of economic growth, but Japan continued to struggle with persistent economic weakness and deflationary forces.

The global stock market rally began to lose momentum during the final months of 2009, and investors appeared to shift their focus from bargain-hunting among beaten-down stocks to fundamental research into higher-quality companies with predictable earnings. However, stocks pulled back sharply in January 2010 when Greece’s debt crisis dominated the headlines, and investors again sought attractive values among stocks that may have been punished too severely. Still, rising corporate earnings helped most non-European markets bounce back by the reporting period’s end, largely erasing previous losses.

International Banks Produced Mixed Results

The Index’s results were bolstered by its holdings in Japan, where large exporters such as Nintendo, Canon, Hitachi and Sony benefited from economic recoveries in overseas markets. An increase in commodity prices helped fuel gains for metals-and-mining giants Rio Tinto and BHP Billiton, both of which are dual-listed in the United Kingdom and Australia, as well as for U.K.-based mining company Anglo American. In Sweden, the Index’s returns were enhanced by apparel retailer Hennes & Mauritz, wireless telecommunications company Sandvik and automakerVolvo, which was recently sold by Ford Motor Company to Chinese carmaker Zhejiang Geely Holding Group.

Results among the Index’s bank holdings proved to be more varied. Several Australian banks produced solid results during the reporting period, most notably Commonwealth Bank of Australia, Westpac Banking, and Australia and New Zealand Banking Group. On the other hand, banks in Spain, Italy, France and Greece undermineded the Index’s performance as the European debt crisis intensified. In Spain, laggards included Banco Santander, Banco BilbaoVizcaya Argentaria and Banco Popular Español. UniCredit and Societe Generale disappointed in Italy

and France, respectively. On an absolute basis, banks in Greece produced the most significant declines for the Index, as National Bank of Greece, Alpha Bank, Piraeus Bank and EFG Eurobank Ergasias posted stock price declines of 50% or more.While these developments certainly were significant, Greece comprises a relatively small portion of the Index, helping to cushion its impact on overall performance.

From a market sector standpoint, stocks in the distribution services, producer manufacturing, non-energy minerals, electronic technology and process industries industry groups contributed positively to the Index’s performance, while the communications, finance, utilities and energy minerals sectors generally lost value.

Index Funds Offer Diversification Benefits

An as index fund, we attempt to replicate the returns of the MSCI EAFE Index by closely approximating its composition. In our view, one of the greatest benefits of an index fund is that it offers a broadly diversified investment vehicle that can help investors manage risks by limiting the impact on the overall portfolio of unexpected losses in any single country, industry group or holding.

May 17, 2010

Equity funds are subject generally to market, market sector, market liquidity, issuer, and investment style risks, among other factors, to varying degrees, all of which are more fully described in the fund’s prospectus.

The fund’s performance will be influenced by political, social and economic factors affecting investments in foreign companies. Special risks associated with investments in foreign companies include exposure to currency fluctuations, less liquidity, less developed or less efficient trading markets, lack of comprehensive company information, political instability and differing auditing and legal standards.

Total return includes reinvestment of dividends and any capital gains paid. Past performance is no guarantee of future results. Share price, yield and investment return fluctuate such that upon redemption, fund shares may be worth more or less than their original cost.

SOURCE: LIPPER INC. — Reflects reinvestment of net dividends and, where applicable, capital gain distributions.The Morgan Stanley Capital International Europe,Australasia, Far East (MSCI EAFE) Index is an unmanaged index composed of a sample of companies representative of the market structure of European and Pacific Basin countries.The index reflects actual investable opportunities for global investors for stocks that are free of foreign ownership limits or legal restrictions at the country level. Investors cannot invest directly in any index.

NOTES TO FINANCIAL STATEMENTS (Unaudited)

NOTE 1—Significant Accounting Policies:

Dreyfus International Stock Index Fund (the “fund”) is a separate non-diversified series of Dreyfus Index Funds, Inc. (the “Company”), which is registered under the Investment Company Act of 1940, as amended (the “Act”), as an open-end management investment company and operates as a series company currently offering three series, including the fund.The fund’s investment objective is to match the performance of the Morgan Stanley Capital International Europe, Australasia, Far East Free Index (MSCI EAFE^®). The Dreyfus Corporation (the “Manager” or “Dreyfus”), a wholly-owned subsidiary of The Bank of New York Mellon Corporation (“BNY Mellon”), serves as the fund’s investment adviser. MBSC Securities Corporation (the “Dist ributor”), a wholly-owned subsidiary of the Manager, is the distributor of the fund’s shares, which are sold to the public without a sales charge.

The Company accounts separately for the assets, liabilities and operations of each series. Expenses directly attributable to each series are charged to that series’ operations; expenses which are applicable to all series are allocated among them on a pro rata basis.

The Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) is the exclusive reference of authoritative U.S. generally accepted accounting principles (“GAAP”) recognized by the FASB to be applied by nongovernmental entities.Rules and interpretive releases of the Securities and Exchange Commission (“SEC”) under authority of federal laws are also sources of authoritative GAAP for SEC registrants. The fund’s financial statements are prepared in accordance with GAAP, which may require the use of management estimates and assumptions.Actual results could differ from those estimates.

The Company enters into contracts that contain a variety of indemnifications. The fund’s maximum exposure under these arrangements is unknown.The fund does not anticipate recognizing any loss related to these arrangements.

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

(a) Portfolio valuation: Investments in securities are valued at the last sales price on the securities exchange or national securities market on which such securities are primarily traded. Securities listed on the National Market System for which market quotations are available are valued at the official closing price or, if there is no official closing price that day, at the last sales price. Securities not listed on an exchange or the national securities market, or securities for which there were no transactions, are valued at the average of the most recent bid and asked prices, except for open short positions, where the asked price is used for valuation purposes. Bid price is used when no asked price is available. Registered investment companies that are not traded on an exchange are valued at their net asset value.When market quotations or officia l closing prices are not readily available, or are determined not to reflect accurately fair value,such as when the value of a security has been significantly affected by events after the close of the exchange or market on which the security is principally traded (for example, a foreign exchange or market), but before the fund calculates its net asset value, the fund may value these investments at fair value as determined in accordance with the procedures approved by the Board of Directors. Fair valuing of securities may be determined with the assistance of a pricing service using calculations based on indices of domestic securities and other appropriate indicators, such as prices of relevant American Depository Receipts and futures contracts. For other securities that are fair valued by the Board of Directors, certain factors may be considered such as: fundamental analytical data, the nature and duration of restrictions on disposition, an evaluation of the forces that influence the market in which the secur ities are purchased and sold, and public trading in similar securities of the issuer or comparable issuers. Financial futures are valued at the last sales price.Investments denominated in foreign currencies are translated to U.S. dollars at the prevailing rates of exchange. Forward foreign currency exchange contracts (“forward contracts”) are valued at the forward rate.

The fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e. the exit price). GAAP establishes a fair value hierarchy that prioritizes the inputs of valuation techniques used to measure fair value.This hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements).

Additionally, GAAP provides guidance on determining whether the volume and activity in a market has decreased significantly and whether such a decrease in activity results in transactions that are not orderly. GAAP requires enhanced disclosures around valuation inputs and techniques used during annual and interim periods.

Various inputs are used in determining the value of the fund’s investments relating to fair value measurements.These inputs are summarized in the three broad levels listed below:

Level 1—unadjusted quoted prices in active markets for identical investments.

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

Level 3—significant unobservable inputs (including the fund’s own assumptions in determining the fair value of investments).

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used as of April 30, 2010 in valuing the fund’s investments:

In January 2010, FASB issued Accounting Standards Update (“ASU”) No. 2010-06 “Improving Disclosures about Fair Value Measurements”. ASU 2010-06 will require reporting entities to make new disclosures about amounts and reasons for significant transfers in and out of Level 1 and Level 2 fair value measurements as well as inputs and valuation techniques used to measure fair value for both recurring and nonrecurring fair value measurements that fall in either Level 2 or Level 3, and information on purchases, sales, issuances and settlements on a gross basis in the reconciliation of activity in Level 3 fair value measurements. The new and revised disclosures are required to be implemented for fiscal years beginning after December 15, 2009 except for the disclosures surrounding purchases,sales,issuances and settlements on a gross basis in the reconciliation of Level 3 fair value measurements, which are effective f or fiscal years beginning after December 15, 2010. Management is currently evaluating the impact the adoption of ASU No. 2010-06 may have on the fund’s financial statement disclosures.

(b) Foreign currency transactions: The fund does not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held. Such fluctuations are included with the net realized and unrealized gain or loss on investments.

Net realized foreign exchange gains or losses arise from sales of foreign currencies, currency gains or losses realized on securities transactions between trade and settlement date, and the difference between the amounts of dividends, interest and foreign withholding taxes recorded on the fund’s books and the U.S. dollar equivalent of the amounts actually received or paid. Net unrealized foreign exchange gains and losses arise from changes in the value of assets and liabilities other than investments resulting from changes in exchange rates. Foreign currency gains and losses on investments are included with net realized and unrealized gain or loss on investments.

(c) Securities transactions and investment income: Securities transactions are recorded on a trade date basis. Realized gains and losses from securities transactions are recorded on the identified cost basis. Dividend income is recognized on the ex-dividend date and interest income, including, where applicable, accretion of discount and amortization of premium on investments, is recognized on the accrual basis.

Investing in foreign markets may involve special risks and considerations not typically associated with investing in the U.S. These risks include revaluation of currencies, high rates of inflation, repatriation restrictions on income and capital, and adverse political and economic developments. Moreover, securities issued in these markets may be less liquid, subject to government ownership controls and delayed settlements, and their prices may be more volatile than those of comparable securities in the U.S.

(d) Affiliated issuers: Investments in other investment companies advised by the Manager are defined as “affiliated” in the Act.

The Fund 45

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

(e) Dividends to shareholders: Dividends are recorded on the ex-dividend date. Dividends from investment income-net and dividends from net realized capital gains, if any, are normally declared and paid annually, but the fund may make distributions on a more frequent basis to comply with the distribution requirements of the Internal Revenue Code of 1986, as amended (the “Code”).To the extent that net realized capital gains can be offset by capital loss carryovers, it is the policy of the fund not to distribute such gains. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP.

(f) Federal income taxes: It is the policy of the fund to continue to qualify as a regulated investment company, if such qualification is in the best interests of its shareholders, by complying with the applicable provisions of the Code, and to make distributions of taxable income sufficient to relieve it from substantially all federal income and excise taxes.

As of and during the period ended April 30, 2010, the fund did not have any liabilities for any uncertain tax positions.The fund recognizes interest and penalties, if any, related to uncertain tax positions as income tax expense in the Statement of Operations. During the period, the fund did not incur any interest or penalties.

Each of the tax years in the three-year period ended October 31, 2009 remains subject to examination by the Internal Revenue Service and state taxing authorities.

The tax character of distributions paid to shareholders during the fiscal year ended October 31, 2009 was as follows: ordinary income $9,805,885 and long-term capital gains $778,245.The tax character of current year distributions will be determined at the end of the current fiscal year.

NOTE 2—Bank Lines of Credit:

a “Facility”), each to be utilized primarily for temporary or emergency purposes, including the financing of redemptions. In connection therewith, the fund has agreed to pay its pro rata portion of commitment fees for each Facility. Interest is charged to the fund based on rates determined pursuant to the terms of the respective Facility at the time of borrowing. During the period ended April 30, 2010, the fund did not borrow under the Facilities.

NOTE 3—Management Fee and Other Transactions With Affiliates:

(a) Pursuant to a management agreement (“Agreement”) with the Manager, the management fee is computed at the annual rate of .35% of the value of the fund’s average daily net assets, and is payable monthly. Under the terms of the Agreement, the Manager has agreed to pay all the expenses of the fund, except management fees, brokerage fees and commissions, taxes, interest fees, commitment fees, Shareholder Services Plan fees, fees and expenses of non-interested Board members (including counsel fees) and extraordinary expenses. In addition, the Manager is required to reduce its fee in an amount equal to the fund’s allocable portion of the accrued fees and expenses of the non-interested Board members (including counsel fees). Each Board member also serves as a Board member of other funds within the Dreyfus complex (collectively, the 7;Fund Group”). Currently, the Company and 10 other funds (comprised of 33 portfolios) in the Dreyfus Family of Funds pay each Board member their respective allocated portion of an annual retainer of $85,000 and an attendance fee of $10,000 for each regularly scheduled Board meeting, an attendance fee of $2,000 for each separate in-person committee meeting that is not held in conjunction with a regularly scheduled Board meeting and an attendance fee of $1,000 for each Board meeting and separate committee meeting that is conducted by telephone.The Chairman of the Board receives an additional 25% of such compensation and the Audit Committee Chairman receives an additional $15,000 per annum. The Company also reimburses each Board member for travel and out-of-pocket expenses in connection

The Fund 47

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

with attending Board or committee meetings. Subject to the Company’s Emeritus Program Guidelines, Emeritus Board members, if any, receive 50% of the Company’s annual retainer fee and per meeting fee paid at the time the Board member achieves emeritus status.

(b) Under the Shareholder Services Plan, the fund pays the Distributor for the provision of certain services, at the annual rate of .25% of the value of the fund’s average daily net assets.The services provided may include personal services relating to shareholder accounts, such as answering shareholder inquiries regarding the fund and providing reports and other information, and services related to the maintenance of shareholder accounts. The Distributor may make payments to Service Agents (a securities dealer, financial institution or other industry professional) in respect of these services. The Distributor determines the amounts to be paid to Service Agents. During the period ended April 30, 2010, the fund was charged $704,592 pursuant to the Shareholder Services Plan.

The components of “Due to The Dreyfus Corporation and affiliates” in the Statement of Assets and Liabilities consist of: management fees $170,735 and shareholder services plan fees $121,953.

(c) A 2% redemption fee is charged and retained by the fund on certain shares redeemed within sixty days following the date of issuance subject to exceptions, including redemptions made through use of the fund’s exchange privilege. During the period ended April 30, 2010, redemption fees charged and retained by the fund amounted to $19,183.

NOTE 4—Securities Transactions:

The aggregate amount of purchases and sales of investment securities, excluding short-term securities, forward contracts and financial futures, during the period ended April 30, 2010, amounted to $44,191,672 and $13,188,489, respectively.

The fund may invest in shares of certain affiliated investment companies also advised or managed by the adviser. Investments in affiliated investment companies for the period ended April 30, 2010 were as follows:

The provisions of ASC Topic 815 “Derivatives and Hedging” require qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of gains and losses on derivative instruments and disclosures about credit-risk-related contingent features in derivative agreements. The disclosure requirements distinguish between derivatives, which are accounted for as “hedges” and those that do not qualify for hedge accounting. Because investment companies value their derivatives at fair value and recognize changes in fair value through the Statement of Operations, they do not qualify for such accounting. Accordingly, even though a fund’s investments in derivatives may represent economic hedges, they are considered to be non-hedge transactions for purposes of this disclosure.The following tables show the fund’s exposure to different types of market risk as it relates to the Statement of Assets and Liabilities and the Statement of Operations, respectively.

Futures Contracts: In the normal course of pursuing its investment objective, the fund is exposed to market risk, including equity price risk as a result of changes in value of underlying financial instruments.The fund invests in financial futures contracts in order to manage its exposure to or protect against changes in the market.A futures contract represents a commitment for the future purchase or a sale of an asset at a specified date. Upon entering into such contracts, these investments require initial margin deposits with a broker, which consist of cash or cash equivalents. The amount of these deposits is determined by the exchange or Board of Trade on which the contract is traded and is subject to change. Accordingly, variation margin payments are received or made to reflect daily unrealized gains or losses which are recorded in the Statement of Operations. Futures contracts are valued daily at the last sales price established by the Board of Trade or exchange upon which they are traded.When the contracts are closed, the fund recognizes a realized gain or loss.There is minimal counterparty credit risk to the fund with futures, since futures are exchange traded and the

exchange’s clearinghouse, as counterparty to all exchange traded futures, guarantees the futures against default. Contracts open at April 30, 2010 are set forth in the Statement of Financial Futures.

Forward Foreign Currency Exchange Contracts: The fund enters into forward contracts in order to hedge its exposure to changes in foreign currency exchange rates on its foreign portfolio holdings, to settle foreign currency transactions or as a part of its investment strategy. When executing forward contracts, the fund is obligated to buy or sell a foreign currency at a specified rate on a certain date in the future. With respect to sales of forward contracts, the fund incurs a loss if the value of the contract increases between the date the forward contract is opened and the date the forward contract is closed.The fund realizes a gain if the value of the contract decreases between those dates. With respect to purchases of forward contracts, the fund incurs a loss if the value of the contract decreases between the date the forward contract is opened and the date the forward contract is closed.The fund realizes a gain if the value of the contract increases between those dates. Any realized gain or loss which occurred during the period is reflected in the Statement of Operations.The fund is exposed to foreign currency risk as a result of changes in value of underlying financial instruments. The fund is also exposed to credit risk associated with counterparty nonperformance on these forward contracts, which is typically limited to the unrealized gain on each open contract.The following summarizes open forward contracts at April 30, 2010:

INFORMATION ABOUT THE REVIEW AND APPROVAL
OF THE FUND’S MANAGEMENT AGREEMENT (Unaudited)

Analysis of Nature, Extent and Quality of Services Provided to the Fund. The Board members received a presentation from representatives of Dreyfus regarding services provided to the fund and other funds in the Dreyfus fund complex, and discussed the nature, extent and quality of the services provided to the fund pursuant to its Management Agreement. Dreyfus’ representatives reviewed the fund’s distribution of accounts and the relationships Dreyfus has with various intermediaries and the different needs of each. Dreyfus’ representatives noted the various distribution channels for the fund as well as the diverse methods of distribution among other funds in the Dreyfus fund complex, and Dreyfus’ corresponding need for broad, deep and diverse resources to be able to provide ongoing shareholder services to each distribution channel, including tho se of the fund. Dreyfus also provided the number of accounts investing in the fund, as well as the fund’s asset size.

The Board members also considered Dreyfus’ research and portfolio management capabilities and Dreyfus’ oversight of day-to-day fund operations, including fund accounting, administration and assistance in meeting legal and regulatory requirements. The Board members also considered Dreyfus’ extensive administrative, accounting and compliance infrastructure.The Board also considered Dreyfus’ brokerage policies and practices, the standards applied in seeking best execution and Dreyfus’ policies and practices regarding soft dollars.

Comparative Analysis of the Fund’s Performance and Management Fee and Expense Ratio. The Board members reviewed the fund’s performance and comparisons to a group of retail front-end load and no-load pure index international large-cap core funds that are benchmarked against the Morgan Stanley Capital International Europe, Australasia, Far East (Free) Index (the “Performance Group”), and also to a larger universe of funds, consisting of all retail and institutional international large-cap core funds (the “Performance Universe”) selected and provided by Lipper, Inc. (“Lipper”), an independent provider of investment company data.The Board was provided with a description of the methodology Lipper used to select the Performance Group and Performance Universe, as well as the Expense Group and Expense Universe (discussed below). The Board members discussed the results of the comparisons and noted the fund’s average annual total return was variously below, above and at the Performance Group medians for all periods, and was above the Performance Universe medians for all periods, except the three- and ten-year periods ended December 31, 2009 when it was below the Performance Universe medians. Dreyfus also provided a comparison of the fund’s calendar year total returns to the returns of the fund’s benchmark index.

The Board members also discussed the fund’s contractual and actual management fees and expense ratio and reviewed the range of management fees and expense ratios as compared to a comparable group of funds (the “Expense Group”) and a broader group of funds (the “Expense Universe”), each selected and provided by Lipper. The Board members noted that the fund’s contractual management fee was below the Expense Group median, the fund’s actual management fee was at the Expense Group and Expense Universe medians and the fund’s total expense ratio was below the Expense Group and Expense Universe medians. Management noted that, pursuant to the fund’s Management Agreement, Dreyfus pays all of the fund’s expenses, except management fees, shareholder services fees, and certain other

expenses, including the fees and expenses of the independent Board members and their counsel.Additionally, Dreyfus has agreed to reduce its management fee in an amount equal to the fees and expenses of the independent Board members and their counsel.

Representatives of Dreyfus reviewed with the Board members the fees paid to Dreyfus or its affiliates by mutual funds and/or separate accounts with similar investment objectives, policies and strategies as the fund (the “Similar Accounts”), and explained the nature of the Similar Accounts and the differences, from Dreyfus’ perspective, as applicable, in providing services to the Similar Accounts as compared to the fund. The Board analyzed differences in fees paid to Dreyfus and discussed the relationship of the advisory fees paid in light of the services provided.The Board members considered the relevance of the fee information provided for the Similar Accounts to evaluate the appropriateness and reasonableness of the fund’s management fees.

Analysis of Profitability and Economies of Scale. Dreyfus’ representatives reviewed the dollar amount of expenses allocated and profit received by Dreyfus and the method used to determine such expenses and profit.The Board previously had been provided with information prepared by an independent consulting firm regarding Dreyfus’ approach to allocating costs to, and determining the profitability of, individual funds and the entire Dreyfus mutual fund complex. The Board also was informed that the methodology had also been reviewed by an independent registered public accounting firm which, like the consultant, found the methodology to be reasonable. The consulting firm also analyzed where any economies of scale might emerge in connection with the management of the fund. The Board members also considered potential benefits to Dreyfus from acting as invest ment adviser and noted there were no soft dollar arrangements with respect to trading the fund’s investments.

ship to the mix of services provided by Dreyfus, including the nature, extent and quality of such services and that a discussion of economies of scale is predicated on a fund having achieved a substantial size with increasing assets and that, if a fund’s assets had been static or decreasing, the possibility that Dreyfus may have realized any economies of scale would be less. It also was noted that Dreyfus did not realize a profit on the fund’s operations.

At the conclusion of these discussions, the Board agreed that it had been furnished with sufficient information to make an informed business decision with respect to continuation of the Management Agreement. Based on the discussions and considerations as described above, the Board made the following conclusions and determinations.

The Board concluded that the nature, extent and quality of the services provided by Dreyfus are adequate and appropriate.
The Board was generally satisfied with the fund’s relative performance.
The Board concluded that the fee paid by the fund to Dreyfus was reasonable in light of the considerations described above.
The Board determined that the economies of scale which may accrue to Dreyfus and its affiliates in connection with the management of the fund had been adequately considered by Dreyfus in connection with the management fee rate charged to the fund and that, to the extent in the future it were determined that material economies of scale had not been shared with the fund, the Board would seek to have those economies of scale shared with the fund.

The Board members considered these conclusions and determinations, along with information received on a routine and regular basis throughout the year, and, without any one factor being dispositive, the Board determined that continuation of the Management Agreement was in the best interests of the fund and its shareholders.

Dreyfus
S&P 500 Index Fund

A LETTER FROM THE CHAIRMAN AND CEO

Dear Shareholder:

We are pleased to present this semiannual report for Dreyfus S&P 500 Index Fund, covering the six-month period from November 1, 2009, through April 30, 2010.

For information about how the fund performed during the reporting period, as well as general market perspectives, we have provided a Discussion of Fund Performance.

Thank you for your continued confidence and support.

Chairman and Chief Executive Officer
The Dreyfus Corporation

DISCUSSION OF FUND PERFORMANCE

For the period of November 1, 2009, through April 30, 2010, as provided by Thomas Durante, CFA, Portfolio Manager

Fund and Market Performance Overview

For the six-month period ended April 30, 2010, Dreyfus S&P 500 Index Fund produced a total return of 15.46%.¹In comparison, the Standard & Poor’s 500 Composite Stock Price Index (the “S&P 500 Index”), the fund’s benchmark, produced a 15.66% return for the same period.^2,3

Large-cap stocks generally produced positive absolute returns during the reporting period, as investor sentiment was buoyed by a sustained U.S. economic recovery. The difference in returns between the fund and the S&P 500 Index was primarily the result of transaction costs and operating expenses that are not reflected in the S&P 500 Index’s return.

The Fund’s Investment Approach

The fund seeks to match the total return of the S&P 500 Index by generally investing in all 500 stocks in the S&P 500 Index in proportion to their respective weighting. Often considered a barometer for the stock market in general, the S&P 500 Index is made up of 500 widely held common stocks across 10 economic sectors. Each stock is weighted by its float-adjusted market capitalization; that is, larger companies have greater representation in the S&P 500 Index than smaller ones.

Economic Rebound Helped Buoy the Equity Markets

When the reporting period began, the U.S. economy had returned to growth, aided in large part by a number of fiscal and monetary stimulus programs. Improving manufacturing activity and an apparent bottoming of housing prices helped to bolster confidence among businesses, consumers and investors. In this environment, consumer and corporate spending improved, and stock and commodity prices rose sharply. However, a number of economic headwinds remained—including stubbornly high unemployment and foreclosure rates—and the economic rebound so far has proved to be less robust than most previous recoveries.

The Fund 3

DISCUSSION OF FUND PERFORMANCE (continued)

Indeed, faced with the subpar recovery and low inflation, the Federal Reserve Board (the “Fed”) made it clear throughout the reporting period that it would continue to employ all available tools to stimulate economic growth. In each of five meetings of its Federal Open Market Committee from November 2009 through April 2010, the Fed maintained the overnight federal funds rate in an unprecedented low range between 0% and 0.25%.The Fed consistently reiterated at the conclusion of those meetings that it intended to keep interest rates low for an “extended period.”

S&P 500 Index Posted Gains in All Market Sectors

All 10 of the economic sectors that comprise the S&P 500 Index produced positive absolute returns during the reporting period, a testament to the breadth of the economic recovery. Much of the S&P 500 Index’s positive performance stemmed from the information technology sector, where stocks generally gained value after posting steep declines in the previous year. Results from technology companies were further fueled by an uptick in consumer and corporate spending. Cost-cutting measures, such as staff reductions, factory closures and moving operations to lower-cost sites, also helped boost performance within the sector. Hardware and software companies with significant exposure to overseas markets fared especially well. In fact, many technology firms expanded their overseas presence during the reporting period, made possible, in part, by their ability to borrow money at low interest rates. Videoconferencing providers, which helped their business customers reduce travel costs, also ranked among the sector’s top performers.

Industrial stocks posted above-average results, as aerospace and defense companies performed well amid continued geopolitical uncertainty. Railroad stocks benefited when shipping volumes increased in the improving economy. Industrial companies that create fuel efficiencies for corporate customers also gained substantial value.

A number of consumer discretionary stocks posted relatively strong results, as specialty retailers, automotive retailers and department stores rebounded from previously beaten-down levels. Improved consumer

spending during the reporting period created a “barbell” of positive performance from low-cost casual dining chains on one end to upscale hotels on the other. Media companies advanced in anticipation of greater advertising spending.

Returns were less impressive in the telecommunications services and utilities sectors.The S&P 500 Index’s greater laggards included some of its traditionally defensive components, including companies with large cash reserves that had held up relatively well during the recession. Investors felt more comfortable assuming greater risks as the economy recovered, and they turned away from defensive companies in favor of more speculative stocks.

Index Funds Offer Diversification Benefits

As an index fund, we attempt to replicate the returns of the S&P 500 Index by closely approximating its composition. In our view, one of the greatest benefits of an index fund is that it offers a broadly diversified investment vehicle that can help investors manage risks by limiting the impact on the overall portfolio of unexpected losses in any single industry group or holding.

NOTES TO FINANCIAL STATEMENTS (Unaudited)

NOTE 1—Significant Accounting Policies:

Dreyfus S&P 500 Index Fund (the “fund”) is a separate non-diversified series of Dreyfus Index Funds, Inc. (the “Company”), which is registered under the Investment Company Act of 1940, as amended (the “Act”), as an open-end management investment company and operates as a series company currently offering three series, including the fund.The fund’s investment objective is to match the performance of the Standard & Poor’s 500 Composite Stock Price Index.The Dreyfus Corporation (the “Manager” or “Dreyfus”), a wholly-owned subsidiary of The Bank of New York Mellon Corporation (“BNY Mellon”), serves as the fund’s investment adviser. MBSC Securities Corporation (the “Distributor”), a wholly-owned subsidiary of the Manager, is the distributor of the fund’s shares, which are sold to the public without a sales charge.

National Market System for which market quotations are available are valued at the official closing price or, if there is no official closing price that day, at the last sales price. Securities not listed on an exchange or the national securities market, or securities for which there were no transactions, are valued at the average of the most recent bid and asked prices, except for open short positions, where the asked price is used for valuation purposes. Bid price is used when no asked price is available. Registered investment companies that are not traded on an exchange are valued at their net asset value.When market quotations or official closing prices are not readily available, or are determined not to reflect accurately fair value, such as when the value of a security has been significantly affected by events after the close of the exchange or market on which the security is principally traded (for example, a foreign exc hange or market), but before the fund calculates its net asset value, the fund may value these investments at fair value as determined in accordance with the procedures approved by the Board of Directors. Fair valuing of securities may be determined with the assistance of a pricing service using calculations based on indices of domestic securities and other appropriate indicators, such as prices of relevant American Depository Receipts and futures contracts. For other securities that are fair valued by the Board of Directors, certain factors may be considered such as: fundamental analytical data, the nature and duration of restrictions on disposition, an evaluation of the forces that influence the market in which the securities are purchased and sold, and public trading in similar securities of the issuer or comparable issuers. Financial futures are valued at the last sales price.

The Fund 29

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

Various inputs are used in determining the value of the fund’s investments relating to fair value measurements.These inputs are summarized in the three broad levels listed below:

Level 1—unadjusted quoted prices in active markets for identical investments.

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

Level 3—significant unobservable inputs (including the fund’s own assumptions in determining the fair value of investments).

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used as of April 30, 2010 in valuing the fund’s investments:


		Level 2—Other	Level 3—

^††	Other financial instruments include derivative instruments, such as futures, forward foreign currency
	exchange contracts, swap contracts and options contracts.Amounts shown represent unrealized
	appreciation (depreciation), or in the case of options, market value at period end.

In January 2010, FASB issued Accounting Standards Update ("ASU") No. 2010-06 “Improving Disclosures about Fair Value Measurements". ASU 2010-06 will require reporting entities to make new disclosures about amounts and reasons for significant transfers in and out of Level 1 and Level 2 fair value measurements as well as inputs and valuation techniques used to measure fair value for both recurring and nonrecurring fair value measurements that fall in either Level 2 or Level 3, and information on purchases, sales, issuances and settlements on a gross basis in the reconciliation of activity in Level 3 fair value measurements. The new and revised disclosures are required to be implemented for fiscal years beginning after December 15, 2009 except for the disclosures surrounding purchases,sales,issuances and settlements on a gross basis in the reconciliation of Level 3 fair value measurements, which are effective for fiscal years beginning after December 15, 2010. Management is currently evaluating the impact the adoption of ASU No. 2010-06 may have on the fund’s financial statement disclosures.

(b) Securities transactions and investment income: Securities transactions are recorded on a trade date basis. Realized gains and losses from securities transactions are recorded on the identified cost basis. Dividend income is recognized on the ex-dividend date and interest income, including, where applicable, accretion of discount and amortization of premium on investments, is recognized on the accrual basis.

Pursuant to a securities lending agreement with The Bank of New York Mellon, a subsidiary of BNY Mellon and an affiliate of Dreyfus, the fund may lend securities to qualified institutions. It is the fund’s policy that, at origination, all loans are secured by collateral of at least 102% of the value of U.S. securities loaned and 105% of the value of foreign securities loaned. Collateral equivalent to at least 100% of the market value of securities on loan is maintained at all times. Collateral is either in the form of cash, which can be invested in certain money market mutual funds managed by the Manager, U.S. Government and Agency securities or letters of credit.The fund is entitled to receive all

The Fund 31

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

income on securities loaned, in addition to income earned as a result of the lending transaction. Although each security loaned is fully collateralized, the fund bears the risk of delay in recovery of, or loss of rights in, the securities loaned should a borrower fail to return the securities in a timely manner. During the period ended April 30, 2010, The Bank of New York Mellon earned $41,364 from lending portfolio securities, pursuant to the securities lending agreement.

(c) Affiliated issuers: Investments in other investment companies advised by the Manager are defined as “affiliated” in the Act.

(d) Dividends to shareholders: Dividends are recorded on the ex-dividend date. Dividends from investment income-net and dividends from net realized capital gains, if any, are normally declared and paid annually, but the fund may make distributions on a more frequent basis to comply with the distribution requirements of the Internal Revenue Code of 1986, as amended (the “Code”).To the extent that net realized capital gains can be offset by capital loss carryovers, it is the policy of the fund not to distribute such gains. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP.

(e) Federal income taxes: It is the policy of the fund to continue to qualify as a regulated investment company, if such qualification is in the best interests of its shareholders, by complying with the applicable provisions of the Code, and to make distributions of taxable income sufficient to relieve it from substantially all federal income and excise taxes.

Each of the tax years in the three-year period ended October 31, 2009 remains subject to examination by the Internal Revenue Service and state taxing authorities.

The fund has an unused capital loss carryover of $49,545,241 available for federal income tax purposes to be applied against future net securities profits, if any, realized subsequent to October 31, 2009. If not applied, $9,724,313 of the carryover expires in fiscal 2015, $39,787,647 expires in fiscal 2016 and $33,281 expires in fiscal 2017.

The tax character of distributions paid to shareholders during the fiscal year ended October 31, 2009 was as follows: ordinary income $50,992,476. The tax character of current year distributions will be determined at the end of the current fiscal year.

NOTE 2—Bank Lines of Credit:

The fund participates with other Dreyfus-managed funds in a $225 million unsecured credit facility led by Citibank, N.A. and a $300 million unsecured credit facility provided by The Bank of New York Mellon (each, a “Facility”), each to be utilized primarily for temporary or emergency purposes, including the financing of redemptions. In connection therewith, the fund has agreed to pay its pro rata portion of commitment fees for each Facility. Interest is charged to the fund based on rates determined pursuant to the terms of the respective Facility at the time of borrowing. During the period ended April 30, 2010, the fund did not borrow under the Facilities.

NOTE 3—Management Fee and Other Transactions With Affiliates:

(a) Pursuant to a management agreement (“Agreement”) with the Manager, the management fee is computed at the annual rate of .25% of the value of the fund’s average daily net assets and is payable monthly. Under the terms of the Agreement, the Manager has agreed to pay all the expenses of the fund, except management fees, brokerage fees and commissions, taxes, interest fees, commitment fees, Shareholder Services Plan fees, fees and expenses of non-interested Board members (including counsel fees) and extraordinary expenses. In addition, the Manager

The Fund 33

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

is required to reduce its fee in an amount equal to the fund’s allocable portion of the accrued fees and expenses of the non-interested Board members (including counsel fees). Each Board member also serves as a Board member of other funds within the Dreyfus complex (collectively, the “Fund Group”). Currently, the Company and 10 other funds (comprised of 33 portfolios) in the Dreyfus Family of Funds pay each Board member their respective allocated portion of an annual retainer of $85,000 and an attendance fee of $10,000 for each regularly scheduled Board meeting, an attendance fee of $2,000 for each separate in-person committee meeting that is not held in conjunction with a regularly scheduled Board meeting and an attendance fee of $1,000 for each Board meeting and separate committee meeting that is conducted by telephone. The Chairman of the Board receives an additional 25% of such compensation and the Audit Comm ittee Chairman receives an additional $15,000 per annum. The Company also reimburses each Board member for travel and out-of-pocket expenses in connection with attending Board or committee meetings. Subject to the Company’s Emeritus Program Guidelines, Emeritus Board members, if any, receive 50% of the Company’s annual retainer fee and per meeting fee paid at the time the Board member achieves emeritus status.

The components of “Due to The Dreyfus Corporation and affiliates” in the Statement of Assets and Liabilities consist of: management fees $502,888 and shareholder services plan fees $502,888.

NOTE 4—Securities Transactions:

The aggregate amount of purchases and sales of investment securities, excluding short-term securities and financial futures, during the period ended April 30, 2010, amounted to $83,923,803 and $182,721,645, respectively.

Futures Contracts: In the normal course of pursuing its investment objective, the fund is exposed to market risk, including equity price risk

The Fund 35

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

as a result of changes in value of underlying financial instruments.The fund invests in financial futures contracts in order to manage its exposure to or protect against changes in the market. A futures contract represents a commitment for the future purchase or a sale of an asset at a specified date. Upon entering into such contracts, these investments require initial margin deposits with a broker, which consist of cash or cash equivalents. The amount of these deposits is determined by the exchange or Board of Trade on which the contract is traded and is subject to change. Accordingly, variation margin payments are received or made to reflect daily unrealized gains or losses which are recorded in the Statement of Operations. Futures contracts are valued daily at the last sales price established by the Board of Trade or exchange upon which they are traded. When the contracts are closed, the fund recognizes a realized gain or lo ss. There is minimal counterparty credit risk to the fund with futures, since futures are exchange traded and the exchange’s clearinghouse, as counterparty to all exchange traded futures, guarantees the futures against default. Contracts open at April 30, 2010 are set forth in the Statement of Financial Futures.

At April 30, 2010, accumulated net unrealized appreciation on investments was $672,270,001, consisting of $915,476,631 gross unrealized appreciation and $243,206,630 gross unrealized depreciation.

At April 30, 2010, the cost of investments for federal income tax purposes was substantially the same as the cost for financial reporting purposes (see the Statement of Investments).

NOTE 5—Subsequent Events Evaluation:

INFORMATION ABOUT THE REVIEW AND APPROVAL
OF THE FUND’S MANAGEMENT AGREEMENT (Unaudited)

At a meeting of the fund’s Board of Directors held on March 2, 2010, the Board unanimously approved the continuation of the fund’s Management Agreement with Dreyfus for a one-year term ending March 30, 2011. The Board members, none of whom are “interested persons” (as defined in the Investment Company Act of 1940, as amended) of the fund, were assisted in their review by independent legal counsel and met with counsel in executive session separate from representatives of Dreyfus. In approving the continuance of the Management Agreement, the Board members considered all factors that they believed to be relevant, including, among other things, the factors discussed below. In evaluating the Management Agreement, the Board members relied on their knowledge, gained through their meetings and other interactions with Dreyfus, its affiliates, the fund, and the services provided to the fund.The Board also relied on ma terials regularly received throughout the year relating to the investment management and other services provided under the Management Agreement, including (a) information on the investment performance of the fund in comparison to similar mutual funds and benchmark performance indices; (b) general investment outlooks in the markets in which the fund invests; (c) compliance reports; and (d) fund expenses.

Analysis of Nature, Extent and Quality of Services Provided to the Fund. The Board members received a presentation from representatives of Dreyfus regarding services provided to the fund and other funds in the Dreyfus fund complex, and discussed the nature, extent and quality of the services provided to the fund pursuant to its Management Agreement. Dreyfus’ representatives reviewed the fund’s distribution of accounts and the relationships Dreyfus has with various intermediaries and the different needs of each. Dreyfus’ representatives noted the various distribution channels for the fund as well as the diverse methods of distribution among other funds in the Dreyfus fund complex, and Dreyfus’ corresponding need for broad, deep, and diverse resources to be able to provide ongoing shareholder services to each distribution channel, including th ose of the fund. Dreyfus also provided the number of accounts investing in the fund, as well as the fund’s asset size.

The Board members also considered Dreyfus’ extensive administrative, accounting and compliance infrastructure.The Board also considered Dreyfus’ brokerage policies and practices and the standards applied in seeking best execution.

The Board members reviewed the fund’s performance and comparisons to a group of retail no-load S&P 500 Index funds (the “Performance Group”) and to a larger universe of funds, consisting of all retail and institutional S&P 500 Index funds (the “Performance Universe”) selected and provided by Lipper, Inc. (“Lipper”), an independent provider of investment company data.The Board was provided with a description of the methodology Lipper used to select the Performance Group and Performance Universe, as well as the Expense Group and Expense Universe (discussed below). The Board members discussed the results of the comparisons and noted the fund’s average annual total return was slightly below the median of its Performance Group and Performance Universe for the one- and two-year periods ended December 31, 2009. The Board considered the narrow range of returns of funds included in the Performance Group, and observed that the difference between the highest and lowest returns was only 43 basis points. Dreyfus also provided a comparison of the fund’s calendar year total returns to the returns of the fund’s benchmark index.

The Board members also discussed the fund’s contractual and actual management fee and expense ratio and reviewed the range of management fees and expense ratios as compared to the same group of funds included in the Performance Group (the “Expense Group”) and a broader group of funds (the “Expense Universe”), each selected and provided by Lipper.The fund’s actual management fee was higher than the Expense Group and Expense Universe medians, and the fund’s

expense ratio was higher than the Expense Group and Expense Universe medians. Management noted that, pursuant to the fund’s Management Agreement, Dreyfus pays all of the fund’s expenses, except management fees, shareholder services fees, and certain other expenses, including the fees and expenses of the independent Board members and their counsel. Additionally, Dreyfus voluntarily has agreed to reduce its management fee in an amount equal to the fees and expenses of the independent Board members and their counsel.

Representatives of Dreyfus reviewed with the Board members the fees paid to Dreyfus or its affiliates by a mutual fund and separate accounts with similar investment objectives, policies and strategies as the fund (the “Similar Accounts”), and explained the nature of the Similar Accounts and the differences, from Dreyfus’ perspective, as applicable, in providing services to the Similar Accounts as compared to the fund. The Board members considered the relevance of the fee information provided for the Similar Accounts to evaluate the appropriateness and reasonableness of the fund’s management fees. Representatives of Dreyfus noted that mutual fund shares can be sold through different types of distribution channels, including retail direct, intermediary and separate accounts, and that this fund is sold primarily through the intermediary channel in which the intermediaries are paid for their services through a R ule 12b-1 fee and/or revenue sharing payments. The Board reviewed differences in fees paid to Dreyfus and discussed the relationship of the advisory fees and other fees paid in light of the services provided. The Board acknowledged that differences in fees paid by the Similar Accounts and the fund seemed to be consistent with the services provided, which were described in detail in materials previously provided to the Board.

prepared by an independent consulting firm regarding Dreyfus’ approach to allocating costs to, and determining the profitability of, individual funds and the entire Dreyfus mutual fund complex. The Board also was informed that the methodology had also been reviewed by an independent registered public accounting firm which, like the consultant, found the methodology to be reasonable. The consulting firm also analyzed where any economies of scale might emerge in connection with the management of the fund. The Board members evaluated the profitability analysis in light of the relevant circumstances for the fund and the extent to which economies of scale would be realized if the fund grows and whether fee levels reflect these economies of scale for the benefit of fund investors.The Board members also considered potential benefits to Dreyfus from acting as investment adviser and noted there were no soft dollar arrangements with respect to trading the fund’s investments.

The Board then considered Dreyfus’ profitability with respect to the fund as part of their evaluation of whether the fees under the Management Agreement bear a reasonable relationship to the mix of services provided by Dreyfus, including the nature, extent and quality of such services and that a discussion of economies of scale is predicated on a fund having achieved a substantial size with increasing assets and that, if a fund’s assets had been static or decreasing, the possibility that Dreyfus may have realized any economies of scale would be less. It also was noted that Dreyfus received no profit for managing the fund during the year. The Board also considered the fee waiver and expense reimbursement arrangements in place for the fund and their effect on Dreyfus’ profitability.

Agreement. Based on the discussions and considerations as described above, the Board made the following conclusions and determinations.

The Board concluded that the nature, extent and quality of the services provided by Dreyfus are adequate and appropriate.
The Board was generally satisfied with the fund’s relative performance.
The Board concluded that the fee paid by the fund to Dreyfus was reasonable in light of the considerations described above.
The Board determined that the economies of scale which may accrue to Dreyfus and its affiliates in connection with the manage- ment of the fund had been adequately considered by Dreyfus in connection with the management fee rate charged to the fund and that, to the extent in the future it were determined that material economies of scale had not been shared with the fund, the Board would seek to have those economies of scale shared with the fund.

The Board members considered these conclusions and determinations, along with information received on a routine and regular basis throughout the year, and, without any one factor being dispositive, the Board determined that continuation of the fund’s Management Agreement was in the best interests of the fund and its shareholders.

Dreyfus
Smallcap Stock Index Fund

A LETTER FROM THE CHAIRMAN AND CEO

Dear Shareholder:

We are pleased to present this semiannual report for Dreyfus Smallcap Stock Index Fund, covering the six-month period from November 1, 2009, through April 30, 2010.

For information about how the fund performed during the reporting period, as well as general market perspectives, we have provided a Discussion of Fund Performance.

Thank you for your continued confidence and support.

Jonathan R. Baum
Chairman and Chief Executive Officer
The Dreyfus Corporation

DISCUSSION OF FUND PERFORMANCE

For the period of November 1, 2009, through April 30, 2010, as provided by Thomas Durante, CFA, Portfolio Manager

Fund and Market Performance Overview

For the six-month period ended April 30, 2010, Dreyfus Smallcap Stock Index Fund produced a total return of 27.96%.¹In comparison, the Standard & Poor’s SmallCap 600 Index (the “S&P 600 Index”), the fund’s benchmark, produced a 28.14% return for the same period.^2,3

Small-cap stocks generally rallied during the reporting period, as investor sentiment was buoyed by sustained economic recovery. In addition, small-cap stocks posted higher returns, on average, than mid-and large-cap stocks.The difference in returns between the fund and its benchmark was primarily due to transaction costs and fund operating expenses that are not reflected in the benchmark’s return.

The Fund’s Investment Approach

The fund seeks to match the total return of the S&P 600 Index by generally investing in a representative sample of the stocks listed in the S&P 600 Index. The S&P 600 Index is composed of 600 domestic stocks across 10 economic sectors. Each stock is weighted by its market capitalization; that is, larger companies have greater representation in the S&P 600 Index than smaller ones.The fund may also use stock index futures as a substitute for the sale or purchase of stocks.

Economic Recovery Helped Buoy the Equity Markets

When the reporting period began, the U.S. economy had returned to growth, aided in large part by a number of fiscal and monetary stimulus programs. As the recovery gained traction, improving manufacturing activity and an apparent bottoming of housing prices helped to bolster confidence among businesses, consumers and investors. In this environment, consumer and corporate spending improved, and stock and commodity prices rose sharply. However, a number of economic headwinds remained—including stubbornly high unemployment and

foreclosure rates—and the economic rebound so far has proved to be less robust than most previous recoveries.

Indeed, faced with the subpar recovery and low inflation, the Federal Reserve Board (the“Fed”) made it clear throughout the reporting period that it would continue to employ all available tools to stimulate the economy. In each of five meetings of its Federal Open Market Committee from November 2009 through April 2010, the Fed maintained the overnight federal funds rate in an unprecedented low range between 0% and 0.25%. The Fed consistently reiterated at the conclusion of those meetings that it intended to keep interest rates low for an “extended period.”

S&P 600 Index Posted Gains in All Market Sectors

All of the market sectors represented in the S&P 600 Index posted gains for the reporting period. Relative performance was particularly strong in the consumer discretionary sector, where specialty retailers, farming equipment suppliers, office supply stores and department stores rebounded from previously beaten-down levels. Many of these companies also benefited from cost-cutting measures implemented during the recession. A number of textile, apparel and luxury goods companies also advanced due to improved consumer spending, as did casual dining chains.

Financial stocks generated especially robust returns when mending credit markets and low interest rates helped regional banks and other small-cap financial institutions rebound from their previous lows. Real estate investment trusts (REITs) benefited from the combination of a reduction in supply and a less restrictive lending environment.The most robust gains among REITs were produced by those specializing in the apartment, self storage and industrial segments. Commercial banks, thrifts and mortgage finance companies also fared well when housing markets began to stabilize.

A significant portion of the reporting period’s gains in the technology sector can be attributed to semiconductor equipment producers and software developers that cut costs by halting production early in the

downturn, selling off unsold inventories at reduced prices and waiting for demand to return before restocking. Electronic equipment makers also fared well, largely in anticipation of future growth.

Returns were less impressive from the telecommunications services, consumer staples and utilities areas. All three sectors traditionally are considered defensive investments, and they comprise a relatively small portion of the benchmark. Indeed, the S&P 600 Index’s greater laggards included a number of traditionally defensive companies with ample cash reserves that had held up relatively well during the recession. Investors felt more comfortable assuming greater risks as the economy recovered, and they turned away from defensive companies in favor of more speculative stocks.

Index Investing Offers Diversification Benefits

As an index portfolio, our strategy is to attempt to replicate the returns of the S&P 600 Index by investing in a representative sample of the small-cap stocks listed in the S&P 600 Index. The fund offers a diversified investment vehicle that can help investors manage the risks of investing in small-cap stocks by limiting the impact on the overall portfolio of unexpected losses in any single industry group or holding.

May 17, 2010

Equity funds are subject generally to market, market sector, market liquidity, issuer and investment style risks, among other factors, to varying degrees, all of which are more fully described in the fund’s prospectus. Stocks of small-cap companies often experience sharper price fluctuations than stocks of larger-cap companies.

NOTES TO FINANCIAL STATEMENTS (Unaudited)

NOTE 1—Significant Accounting Policies:

Dreyfus Smallcap Stock Index Fund (the “fund”) is a separate non-diversified series of Dreyfus Index Funds, Inc. (the “Company”), which is registered under the Investment Company Act of 1940, as amended (the “Act”), as an open-end management investment company and operates as a series company currently offering three series, including the fund.The fund’s investment objective is to match the performance of the Standard & Poor’s SmallCap 600 Index.The Dreyfus Corporation (the “Manager” or “Dreyfus”), a wholly-owned subsidiary of The Bank of NewYork Mellon Corporation (“BNY Mellon”), serves as the fund’s investment adviser. MBSC Securities Corporation (the “Distributor”), a wholly-owned subsidiary of the Manager, is the distributor of the fund’s shares, which are sold to the public without a sales charge.

The Fund 31

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

National Market System for which market quotations are available are valued at the official closing price or, if there is no official closing price that day, at the last sales price. Securities not listed on an exchange or the national securities market, or securities for which there were no transactions, are valued at the average of the most recent bid and asked prices, except for open short positions, where the asked price is used for valuation purposes. Bid price is used when no asked price is available. Registered investment companies that are not traded on an exchange are valued at their net asset value.When market quotations or official closing prices are not readily available, or are determined not to reflect accurately fair value, such as when the value of a security has been significantly affected by events after the close of the exchange or market on which the security is principally traded (for example, a foreign exc hange or market), but before the fund calculates its net asset value, the fund may value these investments at fair value as determined in accordance with the procedures approved by the Board of Directors. Fair valuing of securities may be determined with the assistance of a pricing service using calculations based on indices of domestic securities and other appropriate indicators, such as prices of relevant American Depository Receipts and futures contracts. For other securities that are fair valued by the Board of Directors, certain factors may be considered such as:fundamental analytical data,the nature and duration of restrictions on disposition, an evaluation of the forces that influence the market in which the securities are purchased and sold, and public trading in similar securities of the issuer or comparable issuers. Financial futures are valued at the last sales price.

Additionally, GAAP provides guidance on determining whether the volume and activity in a market has decreased significantly and

whether such a decrease in activity results in transactions that are not orderly. GAAP requires enhanced disclosures around valuation inputs and techniques used during annual and interim periods.

Various inputs are used in determining the value of the fund’s investments relating to fair value measurements.These inputs are summarized in the three broad levels listed below:

Level 1—unadjusted quoted prices in active markets for identical investments.

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

Level 3—significant unobservable inputs (including the fund’s own assumptions in determining the fair value of investments).

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used as of April 30, 2010 in valuing the fund’s investments:

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

In January 2010, FASB issued Accounting Standards Update (“ASU”) No. 2010-06 “Improving Disclosures about FairValue Measurements”. ASU 2010-06 will require reporting entities to make new disclosures about amounts and reasons for significant transfers in and out of Level 1 and Level 2 fair value measurements as well as inputs and valuation techniques used to measure fair value for both recurring and nonrecur-ring fair value measurements that fall in either Level 2 or Level 3, and information on purchases, sales, issuances and settlements on a gross basis in the reconciliation of activity in Level 3 fair value measurements. The new and revised disclosures are required to be implemented for fiscal years beginning after December 15, 2009 except for the disclosures surrounding purchases, sales, issuances and settlements on a gross basis in the reconciliation of Level 3 fair value measurements, which are effective for fiscal years beginning after December 15, 2010. Management is currently evaluating the impact the adoption of ASU No. 2010-06 may have on the fund’s financial statement disclosures.

Agency securities or letters of credit.The fund is entitled to receive all income on securities loaned, in addition to income earned as a result of the lending transaction. Although each security loaned is fully collateralized, the fund bears the risk of delay in recovery of, or loss of rights in, the securities loaned should a borrower fail to return the securities in a timely manner. During the period ended April 30, 2010, The Bank of New York Mellon earned $132,822 from lending portfolio securities, pursuant to the securities lending agreement.

(c) Affiliated issuers: Investments in other investment companies advised by the Manager are defined as “affiliated” in the Act.

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

Each of the tax years in the three-year period ended October 31, 2009 remains subject to examination by the Internal Revenue Service and state taxing authorities.

The fund has an unused capital loss carryover of $9,572,587 available for federal income tax purposes to be applied against future net securities profits, if any, realized subsequent to October 31, 2009. If not applied, the carryover expires in fiscal 2017.

The tax character of distributions paid to shareholders during the fiscal year ended October 31, 2009 was as follows: ordinary income $10,989,421 and long-term capital gains $49,266,320.The tax character of current year distributions will be determined at the end of the current fiscal year.

NOTE 2—Bank Lines of Credit:

The average amount of borrowings outstanding under the Facilities during the period ended April 30, 2010, was approximately $18,800 with a related weighted average annualized interest rate of 1.40%.

NOTE 3—Management Fee and Other Transactions With Affiliates:

to pay all the expenses of the fund, except management fees, brokerage fees and commissions, taxes, interest fees, commitment fees, Shareholder Services Plan fees, fees and expenses of non-interested Board members (including counsel fees) and extraordinary expenses. In addition, the Manager is required to reduce its fee in an amount equal to the fund’s allocable portion of the accrued fees and expenses of the non-interested Board members (including counsel fees). Each Board member also serves as a Board member of other funds within the Dreyfus complex (collectively, the “Fund Group”). Currently, the Company and 10 other funds (comprised of 33 portfolios) in the Dreyfus Family of Funds pay each Board member their respective allocated portion of an annual retainer of $85,000 and an attendance fee of $10,000 for each regularly scheduled Board meeting, an attendance fee of $2,000 for each separate in-person committee meeting that is not held in conjunction with a regularly scheduled Board meeting and an attendance fee of $1,000 for each Board meeting and separate committee meeting that is conducted by telephone.The Chairman of the Board receives an additional 25% of such compensation and the Audit Committee Chairman receives an additional $15,000 per annum.The Company also reimburses each Board member for travel and out-of-pocket expenses in connection with attending Board or committee meetings. Subject to the Company’s Emeritus Program Guidelines, Emeritus Board members, if any, receive 50% of the Company’s annual retainer fee and per meeting fee paid at the time the Board member achieves emeritus status.

tingent features in derivative agreements. The disclosure requirements distinguish between derivatives, which are accounted for as “hedges” and those that do not qualify for hedge accounting. Because investment companies value their derivatives at fair value and recognize changes in fair value through the Statement of Operations, they do not qualify for such accounting.Accordingly,even though a fund’s investments in derivatives may represent economic hedges, they are considered to be non-hedge transactions for purposes of this disclosure.

Futures Contracts: In the normal course of pursuing its investment objective, the fund is exposed to market risk, including equity price risk as a result of changes in value of underlying financial instruments.The fund invests in financial futures contracts in order to manage its exposure to or protect against changes in the market. A futures contract represents a commitment for the future purchase or a sale of an asset at a specified date. Upon entering into such contracts, these investments require initial margin deposits with a broker, which consist of cash or cash equivalents.The amount of these deposits is determined by the exchange or Board of Trade on which the contract is traded and is subject to change.Accordingly, variation margin payments are received or made to reflect daily unrealized gains or losses which are recorded in the Statement of Operations. Futures contracts are valued daily at the last sales price established by the Board of Trade or exchange upon which they are traded. When the contracts are closed, the fund recognizes a realized gain or loss.

FUND’S MANAGEMENT AGREEMENT (Unaudited) (continued)

Comparative Analysis of the Fund’s Performance and Management Fee and Expense Ratio. The Board members reviewed the fund’s performance and comparisons to a group of retail no-load pure index small-cap core funds and one small-cap growth fund that are benchmarked against the S&P SmallCap 600 Index (the “Performance Group”) and to a larger universe of funds, consisting of all retail and institutional small-cap core funds (the “Performance Universe”) selected and provided by Lipper, Inc. (“Lipper”), an independent provider of investment company data.The Board was provided with a description of the methodology Lipper used to select the Performance Group and Performance Universe, as well as the Expense Group and Expense Universe (discussed below).The Board members discussed the results of the comparisons and noted the fund ’s average annual total return was at or above the Performance Group and Performance Universe medians for all periods, except the one-year period ended December 31, 2009 when it was below the Performance Group and Performance Universe medians. Dreyfus also provided a comparison of the fund’s calendar year total returns to the returns of the fund’s benchmark index.

The Board members also discussed the fund’s contractual and actual management fees and expense ratio and reviewed the range of management fees and expense ratios as compared to a comparable group of funds (the “Expense Group”) and a broader group of funds (the “Expense Universe”), each selected and provided by Lipper. The Board members noted that the fund’s contractual management fee was below the Expense Group median, the fund’s actual management fee was at the Expense Group and Expense Universe medians and the fund’s total expense ratio was below the Expense Group median and at the Expense Universe median. Management noted that, pursuant to the Management Agreement, Dreyfus pays all of the fund’s expenses, except management fees, shareholder services fees, and certain other expenses, including the fees and expenses of the independent Board members and their counsel.Additionally, Dr eyfus has agreed to reduce its management fee in an amount equal to the fees and expenses of the independent Board members and their counsel.

Representatives of Dreyfus reviewed with the Board members the fees paid to Dreyfus or its affiliates by mutual funds and/or separate accounts with similar investment objectives, policies and strategies as the fund (the “Similar Accounts”), and explained the nature of the Similar Accounts and the differences, from Dreyfus’ perspective, as applicable, in providing services to the Similar Accounts as compared to the fund.The Board analyzed differences in fees paid to Dreyfus and discussed the relationship of the advisory fees paid in light of the services provided. The Board members considered the relevance of the fee information provided for the Similar Accounts to evaluate the appropriateness and reasonableness of the fund’s management fees.

It was noted that the Board members should consider Dreyfus’ profitability with respect to the fund as part of their evaluation of whether the fees under the Management Agreement bear a reasonable relationship to the mix of services provided by Dreyfus, including the nature, extent and quality of such services and that a discussion of economies of scale is predicated on a fund having achieved a substantial size with increasing assets and that, if a fund’s assets had been static or decreas-

ing, the possibility that Dreyfus may have realized any economies of scale would be less. It also was noted that Dreyfus did not realize a profit on the fund’s operations.

The Board concluded that the nature, extent and quality of the services provided by Dreyfus are adequate and appropriate.
The Board was generally satisfied with the fund’s relative performance.
The Board concluded that the fee paid by the fund to Dreyfus was reasonable in light of the considerations described above.
The Board determined that the economies of scale which may accrue to Dreyfus and its affiliates in connection with the manage- ment of the fund had been adequately considered by Dreyfus in connection with the management fee rate charged to the fund and that, to the extent in the future it were determined that material economies of scale had not been shared with the fund, the Board would seek to have those economies of scale shared with the fund.
