Example

The Example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	1 Year	3 Years	5 Years	10 Years
Class A	$683	$911	$1,156	$1,860
Class C	$302	$624	$1,073	$2,317
Class I	$83	$259	$450	$1,002

You would pay the following expenses if you did not redeem your shares:

	1 Year	3 Years	5 Years	10 Years
Class A	$683	$911	$1,156	$1,860
Class C	$202	$624	$1,073	$2,317
Class I	$83	$259	$450	$1,002

Portfolio Turnover

The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During the most recent fiscal year, the fund's portfolio turnover rate was 191.46% of the average value of its portfolio.

Principal Investment Strategy

To pursue its goal, the fund normally invests at least 80% of its assets in equity securities of small-cap and mid-cap U.S. companies. The fund currently considers small-cap and mid-cap companies to be those with total market capitalizations, at the time of purchase, that are equal to or less than the total market capitalization of the largest company included in Russell 2500^® Growth Index. The fund’s portfolio managers employ a growth-oriented investment style in managing the fund’s portfolio, which means the portfolio managers seek to identify those small-cap and mid-cap companies which are experiencing or are expected to experience rapid earnings or revenue growth. The portfolio managers focus on high quality companies, especially those with products or services that are believed to be leaders in their market niches. The portfolio managers focus on individual stock selection instead of trying to predict which industries or sectors will perform best and select stocks by:

·Using fundamental research to identify and follow companies considered to have attractive characteristics, such as strong business and competitive positions, solid cash flows and balance sheets, high quality management and high sustainable growth; and

·Investing in a company when the portfolio managers’ research indicates that the company will experience accelerating revenues and expanding operating margins, which may lead to rising estimate trends and favorable earnings surprises.

The fund’s investment strategy may lead it to emphasize certain sectors, such as technology, health care, business services and communications.

Principal Risks

An investment in the fund is not a bank deposit. It is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. It is not a complete investment program. The fund's share price fluctuates, sometimes dramatically, which means you could lose money.

·Risks of stock investing. Stocks generally fluctuate more in value than bonds and may decline significantly over short time periods. There is the chance that stock prices overall will decline because stock markets tend to move in cycles, with periods of rising prices and falling prices. The market value of a stock may decline due to general weakness in the stock market or because of factors that affect the company or its particular industry.

·Small and midsize company risk. Small and midsize companies carry additional risks because the operating histories of these companies tend to be more limited, their earnings and revenues less predictable (and some companies may be experiencing significant losses), and their share prices more volatile than those of larger, more established companies.

·Growth stock risk. Investors often expect growth companies to increase their earnings at a certain rate. If these expectations are not met, investors can punish the stocks inordinately, even if earnings do increase. In addition, growth stocks may lack the dividend yield that may cushion stock prices in market downturns.

·Market sector risk. The fund may significantly overweight or underweight certain companies, industries or market sectors, which may cause the fund's performance to be more or less sensitive to developments affecting those companies, industries or sectors.

Performance

The following bar chart and table provide some indication of the risks of investing in the fund. The bar chart shows changes in the performance of the fund's Class I shares from year to year. The table compares the average annual total returns of the fund's shares to those of a broad measure of market performance. The fund's past performance (before and after taxes) is no guarantee of future results. Sales charges, if any, are not reflected in the bar chart, and if those charges were included, returns would have been less than those shown. More recent performance information may be available at www.dreyfus.com.

Year-by-Year Total Returns as of 12/31 each year (%) Class I
	Best Quarter Q2, 2003: 19.24% Worst Quarter Q3, 2001: -24.33%

After-tax performance is shown only for Class I shares. After-tax performance of the fund’s other share classes will vary. After-tax returns are calculated using the historical highest individual federal marginal tax rates, and do not reflect the impact of state and local taxes. Actual after-tax returns depend on the investor's tax situation and may differ from those shown, and the after-tax returns shown are not relevant to investors who hold their shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

The performance figures for the fund’s Class A and Class C shares for periods prior to 3/31/09 reflect the performance of the fund’s Class I shares, adjusted to reflect each share class’ applicable sales charges. Such performance figures have not been adjusted, however, to reflect applicable class fees and expenses; if such fees and expenses had been reflected, the performance shown for Class A and Class C shares for such periods may have been lower.

Average Annual Total Returns (as of 12/31/10) Class (Inception Date)
	1 Year	5 Years	10 Years
Class I (9/1/90) returns before taxes	22.30%	6.29%	5.13%

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase shares through a broker-dealer or other financial intermediary (such as a bank), the fund and its related companies may pay the intermediary for the sale of fund shares and related services.

Ask your salesperson or visit your financial intermediary's website for more information.
