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

How it has done
POAGX share class · total returns with dividends reinvested
Volatility over the last 12 months: 23.10%. Past returns are a record, not a forecast.
Jun 2026 and Jul 2026 have been filed since the trailing figures were struck, so they are not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
