Fund profile

As filed in the prospectus · 2026 Q1

The fund seeks long-term capital growth.

Strategy · summarised

The fund invests in common stocks of medium-sized companies selected for attractive returns on invested capital and signs of business improvement such as accelerating earnings growth or strengthening cash flows. The portfolio managers rely on fundamental analysis of individual companies rather than economic forecasts to identify stocks with favorable growth prospects. The fund may also hold smaller- and larger-sized companies and foreign securities when they meet selection criteria, and may write covered calls on a portion of holdings. Because investment decisions depend on the portfolio managers' analysis of individual company characteristics, performance will diverge from broad market returns.

covering 94% of the fund’s equity

Share of the fund’s equity (by value) in companies whose trailing five-year revenue — or net-income — growth ranks in the top 25% of U.S. public companies. Foreign and newly-listed holdings are excluded, so the figure covers only part of the book. From SEC filings — not investment advice. How we measure this.

These classes hold the same portfolio, so the 9.07pp spread over 3 years is the cost difference between them — roughly 3.02pp a year — not a difference in what they own.
