Dreyfus
Enhanced Income Fund

A LETTER FROM THE CHAIRMAN AND CEO

Dear Shareholder:

We present this last semiannual report for Dreyfus Enhanced Income Fund, covering the six-month period from January 1, 2009, through June 30, 2009.

Although these developments give us reasons for optimism, we remain cautious due to the speed and magnitude of the corporate bond market’s 2009 rebound. Indeed, the market’s advance was fueled more by investors’ renewed appetites for risk than improving business fundamen-tals.We would prefer to see a steadier rise in asset prices supported by more concrete economic data, as the rapid rise increases the possibility that profit-taking could move the market lower. In uncertain markets such as this one, even the most seasoned investors can benefit from professional counsel. To determine how your investments should be positioned for the challenges and opportunities that lie ahead, we continue to stress that you talk regularly with your financial advisor. For information about how the fund performed during the reporting period, as well as market perspectives, we have provided a Discussion of Fund Performance given by the Portfolio Managers.

Thank you for your continued confidence and support.

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

July 15, 2009

DISCUSSION OF FUND PERFORMANCE

For the period of January 1, 2009, through June 30, 2009, as provided by Laurie Carroll and Theodore Bair, Jr., Portfolio Managers

Fund and Market Performance Overview

For the six-month period ended June 30, 2009, Dreyfus Enhanced Income Fund’s Institutional Class shares achieved a total return of –3.28% and the fund’s Investor shares achieved a total return of –2.80%.¹In comparison, the Merrill Lynch U.S. Dollar LIBOR 3-Month Constant Maturity Index, the fund’s benchmark, achieved a total return of 0.73%.²

During the reporting report, the U.S. bond market remained volatile due to the lingering effects of the global financial crisis and recession. However, continued declines among higher-yielding bonds early in the reporting period were offset by a springtime rally as investors grew more comfortable with credit risk. As a result, the fund produced returns that were lower than its benchmark.

Lastly, on August 12, 2009, the fund was liquidated and subsequently ceased operations.

August 13, 2009

1	Total return includes reinvestment of dividends and any capital gains paid, and, for the fund’s Investor shares for periods prior to September 12, 2008, do not take into consideration the maximum initial sales charge imposed on the predecessor fund’s Class A shares. Had these charges been reflected, returns would have been lower. 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. Return figures provided reflect the absorption of certain fund expenses by The Dreyfus Corporation pursuant to an agreement in effect through the fund’s liquidation. Had these expenses not been absorbed, the fund’s returns would have been lower.
2	SOURCE: BLOOMBERG — Reflects reinvestment of dividends and, where applicable, capital gain distributions.The Merrill Lynch U.S. Dollar LIBOR 3-Month Constant Maturity Index is an unmanaged index that measures current interest rates on 3-month constant maturity dollar- denominated deposits.The index does not reflect fees and expenses to which the fund is subject.

UNDERSTANDING YOUR FUND’S EXPENSES (Unaudited)

As a mutual fund investor, you pay ongoing expenses, such as management fees and other expenses. Using the information below, you can estimate how these expenses affect your investment and compare them with the expenses of other funds.You also may pay one-time transaction expenses, including sales charges (loads) and redemption fees, which are not shown in this section and would have resulted in higher total expenses. For more information, see your fund’s prospectus or talk to your financial adviser.

Review your fund’s expenses

The table below shows the expenses you would have paid on a $1,000 investment in Dreyfus Enhanced Income Fund from January 1, 2009 to June 30, 2009. It also shows how much a $1,000 investment would be worth at the close of the period, assuming actual returns and expenses.


Expenses and Value of a $1,000 Investment
assuming actual returns for the six months ended June 30, 2009
	Institutional	Investor
Expenses paid per $1,000^†	$ 1.80	$ 3.18
Ending value (after expenses)	$967.20	$972.00

COMPARING YOUR FUND’S EXPENSES WITH THOSE OF OTHER FUNDS (Unaudited)

Using the SEC’s method to compare expenses

The Securities and Exchange Commission (SEC) has established guidelines to help investors assess fund expenses. Per these guidelines, the table below shows your fund’s expenses based on a $1,000 investment, assuming a hypothetical 5% annualized return. You can use this information to compare the ongoing expenses (but not transaction expenses or total cost) of investing in the fund with those of other funds.All mutual fund shareholder reports will provide this information to help you make this comparison. Please note that you cannot use this information to estimate your actual ending account balance and expenses paid during the period.


Expenses and Value of a $1,000 Investment
assuming a hypothetical 5% annualized return for the six months ended June 30, 2009
	Institutional	Investor
Expenses paid per $1,000^†	$ 1.86	$ 3.26
Ending value (after expenses)	$1,022.96	$1,021.57

† Expenses are equal to the fund’s annualized expense ratio of .37% for Institutional Shares and .65% for Investor shares, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period).

FINANCIAL HIGHLIGHTS

Please note that the financial highlights information in the following tables for the fund’s Institutional and Investor shares represents the financial highlights of the Institutional and Class A shares, respectively, of the fund’s predecessor, BNY Hamilton Enhanced Income Fund (“Enhanced Income Fund”), before the fund commenced operations as of the close of business on September 12, 2008, and represents the performance of the fund’s Institutional and Investor shares thereafter. Before the fund commenced operations, all of the assets of the Enhanced Income Fund were transferred to the fund in exchange for Institutional and Investor shares of the fund in a tax-free reorganization. Total return shows how much an investment in the fund would have increased (or decreased), assuming all dividends and distributions were reinvested.These figures have been derived from the fund’s and the fund’s predecessor’s financial statements.

NOTES TO FINANCIAL STATEMENTS (Unaudited)

NOTE 1—Significant Accounting Policies:

Dreyfus Enhanced Income Fund (the “fund”) is a separate diversified series of Dreyfus Premier Investment 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 nine series, including the fund. The fund’s investment objective is high current income with preservation of capital and maintenance of liquidity.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.

As of the close of business on September 12, 2008, pursuant to an Agreement and Plan of Reorganization previously approved by the fund’s Board of Directors, all of the assets, subject to the liabilities, of BNY Hamilton Enhanced Income Fund (“Enhanced Income Fund”), a series of BNY Hamilton Funds, were transferred to the fund in exchange for corresponding class of shares of Common Stock of the fund of equal value. Shareholders of Institutional shares and Class A of Hamilton Enhanced Income Fund received Institutional shares and Investor shares of the fund, respectively, in each case in an amount equal to the aggregate net asset value of their investment in Enhanced Income Fund at the time of the exchange.The net asset value of the fund’s shares on the close of business September 12, 2008, after the reorganization was $1.74 for Institutional shares and $1.75 for Investor shares, and a total of 7,358,435 Institutional shares and 787,846 Investor shares, representing net assets of $14,198,125 (including $787,393 net unrealized depreciation on investments) were issued to shareholders of Hamilton Enhanced Income Fund shareholders in the exchange. The exchange was a tax-free event to shareholders. Enhanced Income Fund is the Accounting Survivor and its historical performance is presented for periods through September 12, 2008.

The Fund 13

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

MBSC Securities Corporation (the “Distributor”), a wholly-owned subsidiary of the Manager, is the distributor of the funds’ shares, which are sold to the public without a sales charge.The fund is authorized to issue 50 million shares of $.001 Common Stock in each of the following classes of shares:Institutional and Investor.Other differences between the classes include the services offered to and the expenses borne by each class, the allocation of certain transfer agency costs and certain voting rights. Income, expenses (other than expenses attributable to a specific class), and realized and unrealized gains or losses on investments are allocated to each class of shares based on its relative net assets.

As of June 30, 2009, MBC Investments Corp., an indirect subsidiary of BNY Mellon, held 5,714 Investor shares of the fund.

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 fund’s financial statements are prepared in accordance with U.S. generally accepted accounting principles, which may require the use of management estimates and assumptions. Actual results could differ from those estimates.

The fund 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.

(a) Portfolio valuation: Investments in securities excluding short-term investments (other than U.S.Treasury Bills), are valued each business day by an independent pricing service (the “Service”) approved by the Board of Directors. Investments for which quoted bid prices are readily available and are representative of the bid side of the market in

the judgment of the Service are valued at the mean between the quoted bid prices (as obtained by the Service from dealers in such securities) and asked prices (as calculated by the Service based upon its evaluation of the market for such securities). Other investments (which constitute a majority of the portfolio securities) are valued as determined by the Service, based on methods which include consideration of: yields or prices of securities of comparable quality, coupon, maturity and type; indications as to values from dealers; and general market conditions. Restricted securities, as well as securities or other assets for which recent market quotations are not readily available,that are not valued by a pricing service approved by the Board of Directors, or are determined by the fund not to reflect accurately fair value, are valued at fair value as determined in good faith under the direction of the Board of Directors. The factors that may be considered when fair valuing a security include 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. Short-term investments, excluding U.S.Treasury Bills, are carried at amortized cost, which approximates value. Registered investment companies that are not traded on an exchange are valued at their net asset value. Financial futures and options, which are traded on an exchange, are valued at the last sales price on the securities exchange on which such securities are primarily traded or at the last sales price on the national securities market on each business day. Options traded over-the-counter are priced at the mean between the bid and the asked price.

The fund adopted Statement of Financial Accounting Standards No. 157 “FairValue Measurements” (“FAS 157”). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair value measurements.

The Fund 15

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

Various inputs are used in determining the value of the fund’s investments relating to FAS 157.These inputs are summarized in the three broad levels listed below.

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

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

Level 3—significant unobservable inputs (including the fund’s own assumptions 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 June 30, 2009 in valuing the fund’s investments:


		Level 2—Other	Level 3—
	Level 1—	Significant	Significant
	Quoted	Observable	Unobservable
	Prices	Inputs	Inputs	Total

Other Financial
Instruments^†	—	—	—	—

† 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.

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.

The fund has arrangements with the custodian and cash management bank whereby the fund may receive earnings credits when positive cash balances are maintained, which are used to offset custody and cash management fees. For financial reporting purposes, the fund includes net earnings credits as an expense offset in the Statement of Operations.

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

(d) Concentration of risk: The fund invests primarily in debt securities. Failure of an issuer of the debt securities to make timely interest or principal payments, or a decline or the perception of a decline in the credit quality of a debt security, can cause the debt security’s price to fall, potentially lowering the fund’s share price. High yield (“junk”) bonds involve greater credit risk, including the risk of default, than investment grade bonds, and are considered predominantly speculative with respect to the issuer’s continuing ability to make principal and interest payments. In addition, the value of debt securities may decline due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic conditions, changes in outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment. They may also decline because of factors that affect a particular industry.

(e) Dividends to shareholders: It is the policy of the fund to declare dividends daily from investment income-net. Such dividends are paid monthly.

Global Real Estate

Securities Fund

A LETTER FROM THE CHAIRMAN AND CEO

Dear Shareholder:

We are pleased to present this semiannual report for Dreyfus Global Real Estate Securities Fund, covering the six-month period from January 1, 2009, through June 30, 2009.

The severe global recession and banking crisis that dominated the financial markets at the start of 2009 appear to have eased as of mid-year. Previously frozen credit markets have thawed, giving businesses access to the capital they need to grow.After reaching multi-year lows in early March, equities staged an impressive rally, enabling most major international stock market indices to post gains for the six-month reporting period.While the global economy remains weak overall, we have seen encouraging evidence of potential recovery that could take firmer hold later this year, including signs of healing in the battered financial and manufacturing sectors. Meanwhile, inflation in most developed markets has remained tame in the face of high unemployment and unused manufacturing capacity.

Although these developments give us reasons for optimism, we remain cautious due to the speed and magnitude of the international stock markets’ 2009 rebound. Indeed, the markets’ advance was led mainly by the emerging markets as investors developed renewed appetites for risk. We would prefer to see a steadier rise in stock prices supported by more concrete economic data, as the rapid rise increases the possibility that profit-taking could move the markets lower. In uncertain markets such as these, even the most seasoned investors can benefit from professional counsel.To determine how your investments should be positioned for the challenges and opportunities that lie ahead, we continue to stress that you talk regularly with your financial advisor.

For information about how the fund performed during the reporting period, as well as market perspectives, we have provided a Discussion of Fund Performance given by the fund’s Portfolio Managers.

Thank you for your continued confidence and support.

DISCUSSION OF FUND PERFORMANCE

For the period of January 1, 2009, through June 30, 2009, as provided by Peter Zabierek and Dean Frankel, Portfolio Managers, Urdang Securities Management, Inc., Sub-Investment Adviser

Fund and Market Performance Overview

For the six-month period ended June 30, 2009, Dreyfus Global Real Estate Securities Fund’s Class A shares produced a total return of 5.52%, Class C shares returned 5.27% and Class I shares returned 5.88%.¹In comparison, the FTSE EPRA/NAREIT Global Real Estate Securities Index, the fund’s benchmark, achieved a total return of 5.88% for the same period.²

Heightened risk aversion among global investors early in the reporting period gave way to optimism in the spring, fueling a sustained market rebound. The fund’s results were roughly in line with its benchmark Index, as the fund’s conservative positioning caused it to hold up better than market averages early in the reporting period but lag during the subsequent rally.

The Fund’s Investment Approach

The fund seeks capital appreciation and current income by investing at least 80% of its assets in companies principally engaged in the real estate sector. The fund normally invests at least 40% of its assets in companies located outside the United States, and invests in at least 10 different countries.The fund also may invest in companies located in emerging markets and in companies of any market capitalization. Our proprietary approach quantifies investment opportunity both from a real estate and stock perspective and combines “bottom-up” research with a Relative Value Model that includes direct contact with the companies in the fund’s investable universe.

Real Estate Stocks Staged a Swift Rebound

2009 opened in the midst of a deep and prolonged global recession stemming from rising unemployment, plummeting housing values and depressed consumer sentiment.The economic downturn was intensified

The Fund 3

DISCUSSION OF FUND PERFORMANCE (continued)

by a financial crisis that nearly led to the collapse of the global banking system. The real estate industry was especially damaged as property values plunged and access to capital was nearly frozen.

However, by early March, equity markets staged a quick about-face as investors responded to stabilizing credit markets and beaten-down stock prices.The fear of bankruptcies in the real estate segment also moderated as credit markets recovered and leaner, less leveraged companies regained prudent access to capital.

A Conservative Bias Aided the Fund in the Downturn

The fund’s conservative positioning in the first quarter of 2009 supported its relative performance as anxious investors fled to traditionally defensive stocks.However,this cautious approach limited the fund’s participation in the market rally, when riskier assets came into favor.

An underweighted allocation to weaker U.S. real estate markets early in 2009 supported the fund’s performance, as did an increase in U.S. exposure later in the reporting period when domestic markets rebounded. Strong security selections also enabled the fund to keep pace with its benchmark Index.Winners included National Retail Properties, which produced favorable results over the first quarter of 2009 due to its relatively defensive portfolio of real estate holdings.

Solid stock selections in the United Kingdom, Europe, Canada and Australia benefited the fund’s relative performance. An underweight position in the U.K.’s Land Securities helped protect the fund when the real estate investment trust’s (REIT) stock price fell. Britain’s BigYellow Group benefited from strong brand recognition, a capable management team and sustained demand within the self-storage industry.

On the other hand, the fund’s measured shift away from relatively conservative real estate stocks in Hong King proved to be a drag on performance as nearly $1 trillion of government fiscal stimulus, primarily injected within the banking and real estate areas, allowed economically sensitive stocks in this region to surge higher. Hong Kong’s Link REIT performed well in the earlier defensive environment, but as investors’ risk appetites increased, we reallocated assets into property developer Shimao Property Holdings, a stronger beneficiary of the market rally.Although this move proved advantageous, it was not

made quickly enough to fully capture the positive impact of Shimao Property’s gains on the benchmark Index. Singaporean development companies also benefited as investors became more tolerant of risks, but we remained unconvinced of many of these firms’ long-term earnings power, and the fund did not participate in their relative strength. An overweight position in U.S.-based Alexandria Real Estate Equities also produced a drag as the REIT’s efforts to raise capital and its exposure to real estate development weighed on the stock.

Adopting Clear Regional Strategies

We believe we have corrected course appropriately in response to the financial markets’ general change.We have shifted the fund’s focus away from traditionally conservative companies and into more aggressive —yet fundamentally sound — stocks that we believe are positioned to benefit from the market’s upward momentum.We have maintained an overweighted allocation to discounted Hong Kong securities in anticipation of recovering demand as fiscal stimulus lifts the Chinese real estate segment. Conversely, we have maintained an underweighted position in the European real estate industry due to stifled demand and heavy debt. Finally, we have emphasized companies with healthy balance sheets and easier access to financing, as the failures of weaker companies could create opportunities for stronger firms to obtain assets inexpensively.

1	The total return figures presented for Class A and I shares of the fund reflect the performance of BNY Hamilton Global Real Estate Securities Fund’s (the “predecessor fund”) Class A shares and Institutional shares, respectively, prior to 9/13/08. Performance for each share class includes returns for the predecessor fund (Class A and Class I only) and the current maximum sales load, and reflects current distribution and servicing fees in effect only since the reorganization date.
	Investors should consider, when deciding whether to purchase a particular class of shares, the investment amount, anticipated holding period and other relevant factors. Past performance is no guarantee of future results. Share price and investment return fluctuate such that upon redemption, fund shares may be worth more or less than their original cost. Return figures provided reflect the absorption of certain fund expenses by The Dreyfus Corporation pursuant to an undertaking in effect for Classes A and C through May 1, 2010, and in effect for Class I through September 30, 2010, at which time it may be extended, terminated or modified. Had these expenses not been absorbed, the fund’s returns would have been lower.

NOTES TO FINANCIAL STATEMENTS (Unaudited)

NOTE 1—Significant Accounting Policies:

Dreyfus Global Real Estate Securities Fund (the “fund”) is a separate diversified series of Dreyfus Premier Investment 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 nine series, including the fund.The fund’s investment objective is to maximize total return consisting of capital appreciation and current income. 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. Urdang Securities Management, Inc. (“Urdang”) serves as the fund’s sub-investment advisor. Urdang is a wholly-owned subsidiary of BNY Mellon.

MBSC Securities Corporation (the “Distributor”), a wholly-owned subsidiary of Dreyfus, is the distributor of the fund’s shares.The fund is authorized to issue 50 million shares of $.001 par value Common Stock in the following classes of shares: Class A and Class C and 100 million shares of $.001 par value Common Stock of Class I. Class A shares are subject to a sales charge imposed at the time of purchase. Class C shares are subject to a contingent deferred sales charge (“CDSC”) imposed on Class C shares redeemed within one year of purchase. Class I shares are sold at net asset value per share only to institutional investors. Other differences between the classes include the services offered to and the expenses borne by each class, the allocation of certain transfer agency costs and certain voting rights. Income, expenses (other than expenses attributable to a specific class), and realized and unrealized gains or losses on investments are allocated to each class of shares based on its relative net assets.

Effective December 3, 2008, investments for new accounts were no longer permitted in Class T shares of the fund, except that participants in certain group retirement plans were able to open a new account in Class T shares of the fund, provided that the fund was established as an investment option under the plans before December 3, 2008. On February 4, 2009, the fund issued to each holder of its Class T shares,

in exchange for said shares, Class A shares of the fund having an aggregate net asset value equal to the aggregate net asset value of the shareholder’s Class T shares. Subsequent investments in the fund’s Class A shares made by prior holders of the fund’s Class T shares who received Class A shares of the fund in exchange for their ClassT shares are subject to the front-end sales load schedule that was in effect for Class T shares at the time of the exchange. Otherwise, all other Class A share attributes will be in effect. Effective as of the close of business on February 4, 2009, the fund no longer offers Class T shares.

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.

(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

The Fund 19

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

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 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 ADRs 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. 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.

Various inputs are used in determining the value of the fund’s investments relating to FAS 157.These inputs are summarized in the three broad levels listed below.

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

Level 2—other significant observable inputs (including quoted

prices for similar securities, interest rates, prepayment speeds,

credit risk, etc.).

Level 3—significant unobservable inputs (including the fund’s own

assumptions 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 June 30, 2009 in valuing the fund’s investments:

† 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.

(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 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

The Fund 21

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

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 Dreyfus are defined as “affiliated” in the Act.

(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 distribu-

tions are determined in accordance with income tax regulations, which may differ from U.S. generally accepted accounting principles.

Each of the tax years in the three-year period ended December 31, 2008 remains subject to examination by the Internal Revenue Service and state taxing authorities.

The fund has an unused capital loss carryover of $9,463,089 available for federal income tax purposes to be applied against future net securities profits, if any, realized subsequent to December 31, 2008. If not applied, $561,698 of the carryover expires in fiscal 2015 and $8,901,391 expires in fiscal 2016.

The tax character of distributions paid to shareholders during the fiscal year ended December 31, 2008 was as follows: ordinary income $1,032,854. The tax character of current year distributions will be determined at the end of the current fiscal year.

or emergency purposes, including the financing of redemptions. In connection therewith, the fund has agreed to pay its pro rata portion of Facility 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 the borrowing.

The average amount of borrowings outstanding under the Facilities during the period ended June 30, 2009 was approximately $2,800, with a related weighted average annualized interest rate of 1.62%.

NOTE 3—Management Fee and Other Transactions With Affiliates:

(a) Pursuant to a management agreement (“Agreement”) with Dreyfus, the management fee is computed at an annual rate of .95% of the value of the fund’s average daily net assets and is payable monthly.

Dreyfus has contractually agreed, until September 30, 2010, to waive receipt of its fees and/or assume the expenses of the fund so that the direct expenses of Class I shares (excluding taxes, interest, brokerage commissions, commitment fees on borrowings and extraordinary expenses) do not exceed 1.20%.

Dreyfus has also agreed, until May 1, 2010, to waive receipt of its fees and/or assume the expenses of the fund so that the direct expenses of Class A and Class C shares (excluding taxes, interest, brokerage commissions, commitment fees on borrowings, extraordinary expenses, shareholder services fees and Rule 12b-1 fees) do not exceed 1.35%.

The reduction in expenses, pursuant to the undertakings, amounted to $60,214 during the period ended June 30, 2009.

Pursuant to a sub-investment advisory agreement between Dreyfus and Urdang, Dreyfus pays Urdang a monthly fee at an annual rate of .46% of the value of the fund’s average daily net assets.

During the period ended June 30, 2009, the Distributor retained $361 from commissions earned on sales of the fund’s Class A shares.

(b) Under the Distribution Plan (the “Plan”) adopted pursuant to Rule 12b-1 under the Act, Class C shares pay and Class T shares paid the Distributor for distributing their shares at an annual rate of .75% and .25%, respectively, of the value of their average daily net assets. During the period ended June 30, 2009, Class C and Class T shares were charged $24 and $2, respectively, pursuant to the Plan.

(c) Under the Shareholder Services Plan, Class A and Class C shares pay and Class T shares paid the Distributor at an annual rate of .25% of the value of their average daily net assets for the provision of certain services. 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 June 30, 2009, Class A, Class C and Class T shares were charged $45, $8, and $2, respectively, pursuant to the Shareholder Services Plan.

The fund compensates Dreyfus Transfer, Inc., a wholly-owned subsidiary of Dreyfus, under a transfer agency agreement for providing personnel and facilities to perform transfer agency services for the fund. During the period ended June 30, 2009, the fund was charged $1,783 pursuant to the transfer agency agreement.

The fund compensates The Bank of NewYork Mellon, a subsidiary of BNY Mellon and an affiliate of Dreyfus, under a cash management agreement for performing cash management services related to fund subscriptions and redemptions. During the period ended June 30, 2009, the fund was charged $20 pursuant to the cash management agreement.These fees were offset by earnings credits pursuant to the cash management agreement.

The Fund 25

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

The fund also compensates The Bank of New York Mellon under a custody agreement for providing custodial services for the fund. During the period ended June 30, 2009, the fund was charged $32,767 pursuant to the custody agreement.

During the period ended June 30, 2009, the fund was charged $3,341 for services performed by the Chief Compliance Officer.

The components of “Due to The Dreyfus Corporation and affiliates” in the Statement of Assets and Liabilities consist of: management fees $40,108, Rule 12b-1 distribution plan fees $5, shareholder services plan fees $17, custodian fees $14,897, chief compliance officer fees $1,670 and transfer agency per account fees $95, which are offset against an expense reimbursement currently in effect in the amount of $18,512.

(d) Each Board member also serves as a Board member of other funds within the Dreyfus complex. Annual retainer fees and attendance fees are allocated to each fund based on net assets.

NOTE 4—Securities Transactions:

The aggregate amount of purchases and sales of investment securities, excluding short-term securities and forward contracts, during the period ended June 30, 2009, amounted to $22,856,225 and $20,580,599, respectively.

The fund adopted Statement of Financial Accounting Standards No. 161 “Disclosures about Derivative Instruments and Hedging Activities” (“FAS 161”). FAS 161 requires 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. All changes to accounting policies and disclosures have been made in accordance with FAS 161 and are incorporated for the current period as part of the disclosures within this Note.

During the period ended June 30, 2009, the average notional value of foreign exchange contracts was $129,608, which represented .30% of average net assets.

Forward Foreign Currency Exchange Contracts:The fund may enter 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 an 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 would incur a loss if the value of the contracts increases between the date the forward contracts are opened and the date the forward contracts are closed.The fund realizes a gain if the value of the contracts decreases between those dates. With respect to purchases of forward contracts, the fund would incur a loss if the value of the contracts decreases between the date the forward contracts are opened and the date the forward contracts are closed. The fund realizes a gain if the value of the contracts increases between those dates.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. At June 30, 2009, there were no open forward contracts outstanding.

At June 30, 2009, accumulated net unrealized depreciation on investments was $11,460,627, consisting of $2,320,418 gross unrealized appreciation and $13,781,045 gross unrealized depreciation.

At June 30, 2009, 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).

Large Cap Equity Fund

A LETTER FROM THE CHAIRMAN AND CEO

Dear Shareholder:

We are pleased to present this semiannual report for Dreyfus Large Cap Equity Fund, covering the six-month period from January 1, 2009, through June 30, 2009.

The severe recession and banking crisis that dominated the financial markets at the start of 2009 appear to have moderated as of mid-year. Previously frozen credit markets have thawed, giving businesses access to the capital they need to grow. After reaching multi-year lows in early March, equities staged an impressive rally, enabling most major stock market indices to end the six-month reporting period close to where they began.While the U.S. economy remains weak overall, we have seen encouraging evidence of potential recovery, including a recovering housing market and improvements within certain manufacturing sectors. Meanwhile, inflation has remained tame in the face of high unemployment and unused manufacturing capacity. Although these developments give us reasons for optimism, we remain cautious due to the speed and magnitude of the stock market’s 2009 rebound. Indeed, the market’s advance was led mainly by lower-quality stocks when investors developed renewed appetites for risk. We would prefer to see a steadier rise in stock prices supported by more concrete economic data, as the rapid rise increases the possibility that profit-taking could move the market lower. In uncertain markets such as this one, even the most seasoned investors can benefit from professional counsel. To determine how your investments should be positioned for the challenges and opportunities that lie ahead, we continue to stress that you talk regularly with your financial advisor.

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

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 reporting period of January 1, 2009, through June 30, 2009, as provided by Irene O’Neill, Portfolio Manager

Fund and Market Performance Overview

For the six-month period ended June 30, 2009, Dreyfus Large Cap Equity Fund’s Class A shares produced a total return of 4.32%, Class C shares returned 4.47% and Class I shares returned 5.14%.¹In comparison, the Standard and Poor’s 500 Composite Stock Price Index (“S&P 500 Index”), the fund’s benchmark, achieved a total return of 3.19%.²

Despite a deep recession and severe banking crisis, stocks rallied in the spring of 2009, more than offsetting losses incurred earlier in the year. The fund produced higher returns than its benchmark, primarily due to an early shift to a less defensive investment posture in anticipation of the beginning stages of a cyclical recovery.

The Fund’s Investment Approach

The fund seeks long-term capital appreciation.To pursue this goal, the fund normally invests at least 80% of its assets in equity securities of large-capitalization companies with market capitalizations of $5 billion or more at the time of purchase.

The fund invests primarily in large, established companies that we believe have proven track records and the potential for superior relative earnings growth. The investment process begins with a “top-down” assessment of broad economic, political and social trends and their implications for different market and industry sectors. Fundamental research is used to identify companies with the potential for above-average earnings and revenue growth; sustainable competitive advantage; strong or improving financial condition; and/or earnings power that is either unrecognized or underestimated by the market.

A Sustained Market Rally Lifted Stock Prices

The U.S. stock market continued to decline early in 2009 amid rising unemployment, plunging housing prices and depressed consumer confidence. At the same time, a global banking crisis had reduced

The Fund 3

DISCUSSION OF FUND PERFORMANCE (continued)

credit availability and damaged a number of major financial institu-tions.These influences fueled a bear market that drove the benchmark to multi-year lows.

Market sentiment began to improve in early March, as aggressive remedial measures adopted by government and monetary authorities appeared to avert a collapse of the banking system, and investors looked forward to better economic times. As investors became more tolerant of risk, a sustained rally enabled the market to recover the ground it had lost earlier in the reporting period.

A More Constructive Investment Posture

Early in the year, we began to shift the fund’s investment posture to a less defensive position as the rate of economic deterioration appeared to slow and investors looked forward to a recovery.We trimmed the fund’s exposure to the traditionally defensive consumer staples, health care, telecommunications services and utilities sectors. Instead, we placed greater emphasis on consumer discretionary stocks, especially retailers that historically have been among the first to rally in the early stages of recovery.We boosted the fund’s exposure to the energy sector, where we expected oil prices to rise in response to heavier demand from emerging markets.We also established modestly overweighted positions in the financials sector, where we believed massive intervention by government and monetary authorities would prove effective, and the information technology sector, where companies generally exhibited strong balance sheets and faced few regulatory or overcapacity issues.

The fund’s more aggressive tilt helped it participate more fully in the springtime rally. In addition, our stock selection strategy produced above-average results in the information technology sector during the reporting period, as electronics seller Apple bounced back from earlier weakness, glass producer Corning saw better-than-expected demand for flat-panel television screens, and chip makers Broadcom and Taiwan Semiconductor rallied in anticipation of stronger demand and pricing. In the energy sector, winners included natural gas producer Southwestern Energy, drilling rig operator Nabors Industries and exploration-and-production supplier Smith International. The fund’s energy investments also benefited from underweighted exposure to industry

bellwether Exxon Mobil as investors turned away from traditionally defensive stocks. Among financial stocks, positive contributors included Morgan Stanley, State Street and Invesco, which are relatively sensitive to improving capital markets but depend less than their peers on lending.

On the other hand, the industrials and health care sectors generally weighed on the fund’s relative performance. Industrial conglomerate Textron was hurt by weakness in its credit subsidiary, and heavy equipment manufacturer Caterpillar suffered amid weak global capital spending.The health care sector was generally hurt by slower drug sales and uncertainty regarding government reform efforts, which forced declines in pharmaceutical developer Abbott Laboratories and biotechnology companies Cephalon and Gilead Sciences.

Positioned for a Mild Economic Recovery

We expect that an eventual economic recovery will prove relatively mild as a resumption of previous borrowing and spending behavior by consumers and businesses appears unlikely anytime soon. Indeed, the recent market rally may currently reflect a misplaced degree of optimism among investors over the near term.Therefore, we recently have shifted to a more neutral investment posture. However, we are prepared to return to a more constructive positioning should economic conditions show greater signs of improvement later this year.

1	The total return figures presented for Class A and I shares of the fund reflect the performance of BNY Hamilton Large Cap Equity Fund (the “predecessor fund”) Class A shares and Institutional shares, respectively, prior to 9/13/08. Performance for each share class includes returns for the predecessor fund (Class A and Class I only) and the current maximum sales load, and reflects current distribution and servicing fees in effect only since the reorganization date.
	Investors should consider, when deciding whether to purchase a particular class of shares, the investment amount, anticipated holding period and other relevant factors. Past performance is no guarantee of future results. Share price and investment return fluctuate such that upon redemption, fund shares may be worth more or less than their original cost. Return figures provided reflect the absorption of certain fund expenses by The Dreyfus Corporation pursuant to an undertaking in effect for Classes A and C through May 1, 2010, and in effect for Class I through September 30, 2010, at which time it may be extended, terminated or modified. Had these expenses not been absorbed, the fund’s returns would have been lower.

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

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 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 ADRs 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.

Various inputs are used in determining the value of the fund’s investments relating to FAS 157.These inputs are summarized in the three broad levels listed below.

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

Level 2—other significant observable inputs (including quoted

prices for similar securities, interest rates, prepayment speeds,

credit risk, etc.).

Level 3—significant unobservable inputs (including the fund’s own

assumptions 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 June 30, 2009 in valuing the fund’s investments:

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

(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 U.S. generally accepted accounting principles.

(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 December 31, 2008 remains subject to examination by the Internal Revenue Service and state taxing authorities.

The fund has an unused capital loss carryover of $6,041,050 available for federal income tax purposes to be applied against future net securities profits, if any, realized subsequent to December 31, 2008. If not applied, the carryover expires in fiscal 2016.

The tax character of distributions paid to shareholders during the fiscal year ended December 31, 2008 was as follows: ordinary income $4,819,925, long-term capital gains $14,213,338 and return of capital $3,311,030.The tax character of current year distributions, if any, will be determined at the end of the current fiscal year.

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

Futures Contracts: In the normal course of pursuing its investment objectives, the fund is exposed to market risk (including equity price risk, interest rate risk and foreign currency exchange risk) as a result of changes in value of underlying financial instruments. The fund may invest 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 ofTrade 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 settlement 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. At June 30, 2009, there were no open financial futures contracts outstanding.

At June 30, 2009, accumulated net unrealized depreciation on investments was $27,995,928, consisting of $8,574,945 gross unrealized appreciation and $36,570,873 gross unrealized depreciation.

At June 30, 2009, 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).

Large Cap Growth Fund

A LETTER FROM THE CHAIRMAN AND CEO

Dear Shareholder:

We are pleased to present this semiannual report for Dreyfus Large Cap Growth Fund, covering the six-month period from January 1, 2009, through June 30, 2009.

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

Thank you for your continued confidence and support.

Jonathan R. Baum
Chairman and Chief Executive Officer
The Dreyfus Corporation
July 15, 2009

DISCUSSION OF FUND PERFORMANCE

For the reporting period of January 1, 2009, through June 30, 2009, as provided by Irene O’Neill, Portfolio Manager

Fund and Market Performance Overview

For the six-month period ended June 30, 2009, Dreyfus Large Cap Growth Fund’s Class A shares produced a total return of 7.96%, Class C shares returned 7.68% and Class I shares returned 8.33%.¹In comparison, the Russell 1000 Growth Index (the “Index”), the fund’s benchmark, achieved a total return of 11.53%.²

Despite a deep recession and severe banking crisis, stocks rallied in the spring of 2009, more than offsetting losses incurred earlier in the year. Although the fund participated substantially in the rally, it produced lower returns than its benchmark, primarily due to relative weakness in the health care, producer durables and consumer discretionary sectors.

The Fund’s Investment Approach

The fund invests primarily in large, established companies that we believe have proven track records and the potential for superior relative earnings growth. The investment process begins with a “top-down” assessment of broad economic, political and social trends and their implications for different market and industry sectors. Fundamental research is used to identify companies with the potential for accelerating earnings and revenue growth, favorable market positions, improving operating efficiencies, and/or increasing earnings per share.

A Sustained Market Rally Lifted Stock Prices

The U.S. stock market continued to decline early in 2009 amid rising unemployment, plunging housing prices and depressed consumer confidence. At the same time, a global banking crisis had reduced credit availability and damaged a number of major financial institu-tions.These influences fueled a bear market that drove the benchmark to multi-year lows.

The Fund 3

DISCUSSION OF FUND PERFORMANCE (continued)

Market sentiment began to improve in early March, as aggressive remedial measures adopted by government and monetary authorities appeared to avert a collapse of the banking system, and investors looked forward to better economic times. As investor sentiment improved, a sustained rally enabled the market to recover the ground it had lost earlier in the reporting period. Growth stocks substantially outperformed their value-oriented counterparts in this environment.

A More Constructive Investment Posture

Early in the year, we began to shift the fund to a more constructive positioning as the rate of economic deterioration slowed and investors looked forward to a recovery.We trimmed the fund’s exposure to the traditionally defensive consumer staples and health care sectors, and we placed greater emphasis on consumer discretionary stocks, especially retailers that historically have been among the first to rally in the early stages of recovery.We boosted the fund’s exposure to the integrated oils and other energy sectors, as we expected energy prices to rise in response to heavier demand from emerging markets.We also established modestly overweighted positions in the financial services sector, where we believed massive government intervention would prove effective in repairing credit markets, and the technology sector, where companies generally exhibited strong balance sheets and faced few regulatory or overcapacity issues.

The fund’s more aggressive tilt helped it participate to a significant degree in the springtime rally. However, our security selection strategies in the health care, consumer discretionary and producer durables sectors prevented the fund from matching its benchmark’s performance. The health care sector was generally hurt by slower drug sales and uncertainty regarding government reform efforts, which adversely affected biotech-nology companies Celgene, Cephalon and Gilead Sciences. Contract research provider Pharmaceutical Product Development faltered due to concerns regarding consolidation in the health care sector. The fund’s results in the consumer discretionary sector were undermined by weakness in retail chain Lowe’s Companies.Producer durables companies Emerson Electric and Caterpillar suffered amid expectations of weak global capital spending.

On the other hand, our stock selection strategy produced above-average results in the technology sector during the reporting period, as consumer electronics seller Apple bounced back from earlier weakness, glass producer Corning saw better-than-expected demand for flat-panel television screens, chip maker Broadcom rallied in anticipation of stronger demand and pricing, and online media company Google benefited from a shift in advertising spending to the Internet. In the other energy sector, winners included oil services provider Weatherford International, natural gas producer Southwestern Energy, and exploration-and-production supplier Smith International. Among financial stocks, positive contributors included Goldman Sachs, Invesco and American Express.

Positioned for a Mild Economic Recovery

July 15, 2009

1	The total return figures presented for Class A and I shares of the fund reflect the performance of BNY Hamilton Large Cap Growth Fund’s (the “predecessor fund”) Class A shares and Institutional shares, respectively, prior to 9/13/08. Performance for each share class includes returns for the predecessor fund (Class A and Class I only) and the current maximum sales load, and reflects current distribution and servicing fees in effect only since the reorganization date.
	Investors should consider, when deciding whether to purchase a particular class of shares, the investment amount, anticipated holding period and other relevant factors. Past performance is no guarantee of future results. Share price and investment return fluctuate such that upon redemption, fund shares may be worth more or less than their original cost. Return figures provided reflect the absorption of certain fund expenses by The Dreyfus Corporation pursuant to an undertaking in effect for Classes A and C through May 1, 2010, and in effect for Class I through September 30, 2010, at which time it may be extended, terminated or modified. Had these expenses not been absorbed, the fund’s returns would have been lower.
2	SOURCE: LIPPER INC. — Reflects reinvestment of net dividends and, where applicable, capital gain distributions.The Russell 1000 Growth Index is an unmanaged index that measures the performance of those Russell 1000 companies with higher price-to-book ratios and higher forecasted growth values. Index return does not reflect fees and expenses associated with operating a mutual fund.

NOTES TO FINANCIAL STATEMENTS (Unaudited)

NOTE 1—Significant Accounting Policies:

Dreyfus Large Cap Growth Fund (the “fund”) is a separate diversified series of Dreyfus Premier Investment 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 nine series, including the fund. The fund’s investment objective is long-term capital appreciation.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. The fund is authorized to issue 50 million shares of $.001 par value Common Stock in the following classes of shares: Class A and Class C and 100 million share of $.001 par value Common Stock of Class I. Class A shares are subject to a sales charge imposed at the time of purchase. Class C shares are subject to a contingent deferred sales charge (“CDSC”) imposed on Class C shares redeemed within one year of purchase. Class I shares are sold at net asset value per share only to institutional investors. Other differences between the classes include the services offered to and the expenses borne by each class, the allocation of certain transfer agency costs and certain voting rights. Income, expenses (other than expenses attributable to a specific class), and realized and unrealized gains or losses on investments are allocated to each class of shares based on its relative net assets.

Effective December 3, 2008, investments for new accounts were no longer permitted in ClassT of the fund, except that participants in certain group retirement plans were able to open a new account in Class T of the fund, provided that the fund was established as an investment option under the plans before December 3, 2008. On February 4, 2009, the fund issued to each holder of its Class T shares, in exchange for said shares, Class A shares of the fund having an aggregate net asset value equal to the aggregate net asset value of the shareholder’s Class

T shares. Subsequent investments in the fund’s Class A shares made by prior holders of the fund’s Class T shares who received Class A shares of the fund in exchange for their Class T shares are subject to the front-end sales load schedule that was in effect for Class T shares at the time of the exchange. Otherwise, all other Class A share attributes will be in effect. Effective as of the close of business on February 4, 2009, the fund no longer offers Class T shares.

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.

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

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 ADRs 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.

Various inputs are used in determining the value of the fund’s investments relating to FAS 157.These inputs are summarized in the three broad levels listed below.

Level 1—quoted prices in active markets for identical investments

Level 2—other significant observable inputs (including quoted

prices for similar securities, interest rates, prepayment speeds,

credit risk, etc.).

Level 3—significant unobservable inputs (including the fund’s

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 June 30, 2009 in valuing the fund’s investments:

Large Cap Value Fund

A LETTER FROM THE CHAIRMAN AND CEO

Dear Shareholder:

We are pleased to present this semiannual report for Dreyfus Large CapValue Fund, covering the six-month period from January 1, 2009, through June 30, 2009.

For information about how the fund performed during the reporting period, as well as market perspectives, we have provided a Discussion of Fund Performance given by the fund’s Portfolio Managers.

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 reporting period of January 1, 2009, through June 30, 2009, as provided by Julianne McHugh and Brian Ferguson, Portfolio Managers

Fund and Market Performance Overview

For the six-month period ended June 30, 2009, Dreyfus Large Cap Value Fund’s Class A shares achieved a total return of –1.83%, Class C shares returned –2.00% and Class I shares returned –1.38%.¹

Effective May 1, 2009, the fund’s primary benchmark index was changed from the Standard & Poor’s 500 Composite Stock Price Index (“S&P 500 Index”) to the Russell 1000Value Index (the “Index”), which more accurately reflects the fund’s investment approach. The Russell 1000 Value Index achieved a total return of –2.87% for the six-month period.²The S&P 500 Index returned 3.19% for the same period.³

Despite a deep economic recession and an ongoing banking crisis, stocks rallied in the spring of 2009, offsetting a substantial portion of losses incurred earlier in the year. The fund fared relatively well in this environment, as the success of its security selection strategy in eight of 10 economic sectors enabled it to produce higher returns than its benchmark.

The Fund’s Investment Approach

The fund seeks to provide long-term capital appreciation; its secondary goal is current income.To pursue these goals, the fund normally invests at least 80% of its assets in equity securities of large capitalization companies with market capitalizations of $5 billion or more at the time of purchase.The fund invests primarily in equity securities of U.S. issuers, but may invest up to 20% of its assets in equity securities of foreign issuers, including those in emerging markets.

When choosing stocks, we focus on individual stock selection (a “bottom-up” approach) rather than forecasting stock market trends. We employ a three-step value screening process that seeks to identify the stocks of companies that are underpriced relative to their intrinsic worth or business prospects, and that exhibit sound business fundamentals, positive business momentum or a catalyst that may trigger an improving stock price.

The Fund 3

DISCUSSION OF FUND PERFORMANCE (continued)

A Sustained Market Rally Lifted Stock Prices

The U.S. stock market continued to decline early in 2009 amid rising unemployment, plunging housing prices and depressed consumer confidence. At the same time, a global banking crisis continued to roil the world’s credit markets.These influences fueled a severe bear market that drove stock market averages to multi-year lows.

Market sentiment began to improve in early March, as aggressive measures adopted by government and monetary authorities appeared to avert a collapse of the banking system, and investors looked forward to better economic times. Bargain hunters began to bid beaten-down stock prices higher, fueling a sustained market rally that enabled many stocks to recover much of the ground they had lost earlier in the reporting period.

Energy and Financial Stocks Drove Fund Performance

Our value-oriented stock selection strategy proved relatively ineffective when 2009 began, as investors responded indiscriminately to fear of losses rather than the strengths and weaknesses of individual companies. However, our security selection process worked better during the springtime rally when investors refocused on fundamentals. Consequently, the fund ended the reporting period with above-average returns in eight of the benchmark’s 10 economic sectors. The fund’s relative performance was especially robust in the energy, financial services and technology sectors.

In the economically sensitive energy sector, an underweighted position in Exxon Mobil proved advantageous as investors sold the industry bellwether in favor of more aggressive investments. Similarly, the fund benefited from its lack of exposure to another energy giant, ConocoPhillips. Instead, we emphasized smaller oil services and exploration-and-production companies, including Occidental Petroleum and XTO Energy.

The battered financial services sector rebounded after it was reported in the spring that major U.S. banks had passed government-ordered “stress tests.”We also successfully avoided most of the credit crisis’s more severely damaged financial institutions in favor of healthier companies, such as Northern Trust and JPMorgan Chase & Co. The technology

sector represented the fund’s largest overweighted position, a stance that proved successful as pent-up demand for technology upgrades drove stock prices higher.

The fund’s performance lagged its benchmark in only two market sectors. Results in the consumer discretionary sector were undermined by the fund’s lack of exposure to Ford Motor Company,which gained when its chief U.S. competitors filed for bankruptcy protection.The fund also did not participate fully in a rebound among retailers,where we preferred relatively defensive investments, such as auto parts seller AutoZone. In the telecommunications area, the fund did not own Sprint Nextel Corp., which rallied strongly due to factors we consider unsustainable.

Positioned for an Economic Recovery

Despite the recent market rally, we have continued to find what we believe to be attractively valued opportunities in companies that appear poised to prosper during an economic rebound, particularly in the financial services and technology sectors.We continue to believe that a highly disciplined and selective approach to security selection is required to produce consistently superior performance over the long term.

July 15, 2009

1	The total return figures presented for Class A and I shares of the fund reflect the performance of BNY Hamilton Large Cap Value Fund’s (the “predecessor fund”) Class A shares and Institutional shares, respectively, prior to 9/13/08. Performance for each share class includes returns for the predecessor fund (Class A and Class I only) and the current maximum sales load, and reflects current distribution and servicing fees in effect only since the reorganization date.
	Investors should consider, when deciding whether to purchase a particular class of shares, the investment amount, anticipated holding period and other relevant factors. Past performance is no guarantee of future results. Share price and investment return fluctuate such that upon redemption, fund shares may be worth more or less than their original cost. Return figures provided reflect the absorption of certain fund expenses by The Dreyfus Corporation pursuant to an undertaking in effect for Classes A and C through May 1, 2010, and in effect for Class I through September 30, 2010, at which time it may be extended, terminated or modified.

NOTES TO FINANCIAL STATEMENTS (Unaudited)

NOTE 1—Significant Accounting Policies:

Dreyfus Large CapValue Fund (the “fund”) is a separate diversified series of Dreyfus Premier Investment 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 nine series, including the fund. The fund’s investment objective is long-term capital appreciation.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.

Effective December 3, 2008, investments for new accounts were no longer permitted in ClassT shares of the fund, except that participants in certain group retirement plans were able to open a new account in Class T shares of the fund, provided that the fund was established as an investment option under the plans before December 3, 2008. On February 4, 2009, the fund issued to each holder of its Class T shares, in exchange for said shares, Class A shares of the fund having an

aggregate net asset value equal to the aggregate net asset value of the shareholder’s Class T shares. Subsequent investments in the fund’s Class A shares made by prior holders of the fund’s Class T shares who received Class A shares of the fund in exchange for their ClassT shares are subject to the front-end sales load schedule that was in effect for Class T shares at the time of the exchange. Otherwise, all other Class A share attributes will be in effect. Effective as of the close of business on February 4, 2009, the fund no longer offers Class T shares.

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.

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, foreign exchange or market), but before the fund calculates its net asset value, the fund may value these investments at fair value as deter mined 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 ADRs 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 adopted Statement of Financial Accounting Standards No. 157 “FairValue Measurements” (“FAS 157”). FAS 157 establishes an author itative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair value measurements

Various inputs are used in determining the value of the fund’s invest ments relating to FAS 157.These inputs are summarized in the three broad levels listed below.

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

Level 2—other significant observable inputs (including quoted

prices for similar securities, interest rates, prepayment speeds,

credit risk, etc.).

Level 3—significant unobservable inputs (including the fund’s own

assumptions 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 June 30, 2009 in valuing the fund’s investments:
