American Century Equity Growth Fund I Class

Over

The fund invests at least 80% of its net assets in equity securities. In selecting stocks for the fund, the portfolio managers use quantitative and qualitative management techniques in a multi-step process. First, the managers rank stocks, primarily large capitalization, publicly traded U.S. companies from most attractive to least attractive based on an objective set of measures. The portfolio managers then review the output of the quantitative model and also consider other factors to build a portfolio that they believe will provide a balance between risk and return.
