Investment Objective
Long-term capital growth.

Investment Strategy
The Fund invests principally in equity securities of growth companies. The Fund invests principally in equity securities of companies with market capitalizations greater than that of the largest company included in the Russell 2000^® Index on the last day of the most recent quarter (currently, approximately $8.5 billion, based on the size of the largest company on December 31, 2007). The Fund may at times invest a substantial portion of its assets in technology companies.

The Fund may hold a substantial portion of its assets in cash and cash equivalents, although it will not necessarily do so.

Investment Process
In selecting investments for the Fund, we may look to see:
  •   whether the company has experienced or has the potential for superior earnings-per-share growth;
  •   whether there is a possible catalyst that has the potential to drive earnings and valuations higher, such as new management or a new product launch;
  •   whether the company has a superior management team.

Sell Discipline
We consider selling or initiating the process when:
  •   the price of the security appears relatively high or attains RS Investments' price target;
  •   the company's business fundamentals turn negative;
  •   RS Investments believes that another investment offers a better opportunity;
  •   the stock price declines substantially below the purchase price.

Risk Factors
Investing in mid-size companies can involve risks such as having less publicly available information, higher volatility, and less liquidity than in the case of larger companies. Overweighting investments in certain sectors or industries increases the risk of loss due to general declines in the prices of stocks in those sectors or industries. Investments in technology companies may be highly volatile.

1 "Other Expenses" have been restated to reflect current fees. "Other Expenses" include expenses indirectly incurred by the Fund through investments in certain pooled investment vehicles ("Acquired Funds") of 0.01% or less of the Fund’s average daily net assets for the fiscal year ended December 31, 2006. 2 RS Investments has contractually agreed through April 30, 2008 to reduce its management fee with respect to Class A shares of the Fund to the extent that Class A's Total Annual Fund Operating Expenses (excluding expenses indirectly incurred by the Fund through investments in Acquired Funds, interest, taxes, and extraordinary expenses) exceed 1.49%, and to reduce the management fee paid by each of the other classes of the Fund so that, at all times through April 30, 2008, each of those classes pays management fees at the same rate as do the Class A shares. 3 Risk characteristics are relative to the Russell 1000® Growth Index as of 3/31/08, and for the three-year period.

Performance Update (Class A)
Average Annual Total Returns For Periods ended 3/31/08

Performance quoted represents past performance and does not guarantee future results. Investment return and principal value will fluctuate, so shares, when redeemed, may be worth more or less than their original cost. Please keep in mind that any high double-digit returns are highly unusual and cannot be sustained. The Fund's total gross annual operating expense ratio as of the most current prospectus is as follows: Class A 1.62%, Class K 2.03%. Class A performance quoted "with maximum sales charge" reflects the current maximum sales charge of 4.75%. Please read the prospectus carefully for more information on sales charges as they do not apply in all cases and if applied are reduced for larger purchases. There is no sales charge for Class K shares. Any sales charges are in addition to the Fund's fees and expenses as detailed in the Fund's most current prospectus. Fees and expenses are factored into the net asset value of your shares and any performance numbers we release. Total return figures reflect an expense limitation in effect during the periods shown; without such limitation, the performance shown would have been lower. Performance results assume the reinvestment of dividends and capital gains. The return figures shown do not reflect the deduction of taxes that a shareholder may pay on Fund distributions or the redemption of Fund shares. Current and month-end performance information, which may be lower or higher than that cited, is available by contacting RS Investments at 1-800-766-FUND and is frequently updated on our Web site: www.RSinvestments.com.

Index results assume the reinvestment of dividends paid on the stocks constituting the index. You may not invest in the index, and, unlike the Fund, the index does not incur fees and expenses.
** The S&P 500^® Index is an unmanaged market capitalization-weighted index of 500 stocks designed to measure performance of the broad domestic economy through changes in the aggregate market value of 500 stocks representing all major industries.
