Fund profile

As filed in the prospectus · 2026 Q1

The PRIMECAP Odyssey Aggressive Growth Fund seeks to provide long-term capital appreciation.

Strategy · summarised

The fund invests in common stocks of U.S. companies selected through bottom-up fundamental research for prospects of rapid earnings growth, with particular emphasis on mid- and small-capitalization stocks. The manager seeks companies it believes will outperform the S&P 500 Index over three to five years, identifying catalysts such as new products, new markets, or shifts in industry dynamics. The fund may maintain significant overweight or underweight positions in particular sectors relative to the S&P 500 and may also invest substantial assets in foreign securities. Because the fund emphasizes smaller-capitalization stocks and sector concentrations may diverge materially from the index, performance may differ substantially from broad market returns.
