Fund Profile

What is the fund`s objective?

The fund seeks to provide long-term capital growth. Income is a secondary objective.

What is the fund`s principal investment strategy?

The fund will normally invest at least 80% of net assets in the common stocks of large and medium-sized blue chip growth companies. These are firms that, in our view, are well established in their industries and have the potential for above-average earnings growth. We focus on companies with leading market position, seasoned management, and strong financial fundamentals. Our investment approach reflects our belief that solid company fundamentals (with emphasis on strong growth in earnings per share or operating cash flow) combined with a positive industry outlook will ultimately reward investors with strong investment performance. Some of the companies we target will have good prospects for dividend growth.

In pursuing its investment objective, the fund`s management has the discretion to purchase some securities that do not meet its normal investment criteria, as described abo ve, when it perceives an unusual opportunity for gain. These special situations might arise when the fund`s management believes a security could increase in value for a variety of reasons, including a change in management, an extraordinary corporate event, or a temporary imbalance in the supply of or demand for the securities.

While most assets will be invested in U.S. common stocks, other securities may also be purchased, including foreign stocks, futures, and options, in keeping with fund objectives.

The fund may sell securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into more promising opportunities.

Further information about the fund`s investments, including a review of market conditions and fund strategies and their impact on performance, is available in the annual and semiannual shareholder reports. To obtain free copies of these documents, call 1-800-638-5660. These documents are also available at troweprice.com.

What are the main risks of investing in the fund?

Even well-established growth stocks can be volatile. Since growth companies usually invest a high portion of earnings in their own businesse s, their stocks may lack the dividends that can cushion share prices in a down market. Since many investors buy these stocks because of anticipated superior earnings growth, earnings disappointments often result in sharp price declines. Also, medium-sized companies may have greater volatility than larger ones.

Fund Profile

As with all equity funds, this fund`s share price can fall because of weakness in the broad market, a particular industry, or specific holdings. The market as a whole can decline for many reasons, including adverse political or economic developments here or abroad, changes in investor psy chology, or heavy institutional selling. The prospects for an industry or company may deteriorate because of a variety of factors, including disappointing earnings or changes in the competitive environment. In addition, our assessment of companies held in the fund may prove incorrect, resulting in losses or poor performance even in a rising market. Finally, the fund`s investment approach could fall out of favor with the investing public, resulting in lagging performance versus other types of stock funds.

Foreign stock holdings are subject to the risk that some holdings may lose value because of declining foreign currencies or adverse political or economic events overseas. Investments in futures and options, if any, are subject to additional volatility and potential losses.

As with any mutual fund, there can be no guarantee the fund will achieve its objective.

The fund`s share price may decline, so when you sell your shares, you may lose money. An investment in the fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

How can I tell if the fund is appropriate for me?

Consider your investment goals, your time horizon for achieving them, and your tolerance for risk. If you are willing to accept the risk of investing in established growth stocks in an effort to achieve long-term capital growth, the fund could be appropriate for you. This fund should not represent your complete investment program or be used for short-term trading purposes.

The fund can be used in both regular and tax-deferred accounts, such as IRAs.

Equity investors should have a long-term investment horizon and be willing to wait out bear markets.

How has the fund performed in the past?

The bar chart showing calendar year returns and the average annual total returns table indicate risk by illustrating how much returns can differ from one year to the next and how fund performance compares with that of a comparable market index. Fund past returns (before and after taxes) are not necessarily an indication of future performance.

The fund can also experience short-term performance swings, as shown by the best and worst calendar quarter returns during the years depicted.

Fund Profile

In addition, the average annual total returns table shows hypothetical after-tax returns to suggest how taxes paid by the shareholder may influence returns. Actual after-tax returns depend on each investor`s situation and may differ from those shown. After-tax returns are not relevant if the shares are held in a tax-deferred account, such as a 401(k) or IRA. During periods of fund losses, the post-liquidation after-tax return may exceed the fund`s other returns because the loss generates a tax benefit that is factored into the result.

Returns are based on changes in principal value, reinvested dividends, and capital gain distributions, if any. Returns before taxes do not reflect effects of any income or capital gains taxes. Taxes are computed using the highest federal income tax rate. The after-tax returns reflect the rates applicable to ordinary and qualified dividends and capital gains effective in 2003. The returns do not reflect the impact of state and local taxes. Returns after taxes on distributions reflect the taxed return on the payment of dividends and capital gains. Returns after taxes on distributions and sale of fund shares assume the shares were sold at period-end and, therefore, are also adjusted for any capital gains or losses incurred by the shareholder. Market indexes do not include expenses, which are deducted from fund returns, or taxes.

S&P 500 Index tracks the stocks of 500 U.S. companies.
