American Century Disciplined Growth Fund Investor Class 

The investment seeks long-term capital growth. In selecting stocks for the fund, the portfolio managers initially identify an eligible universe of growth stocks then 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. Second, the portfolio managers use a quantitative model to build a portfolio of stocks from the ranking that they believe will provide the optimal balance between risk and expected return.
