The Fund seeks long-term growth of capital.
The fund invests at least 80% of assets in equity securities of U.S. companies with the largest market capitalizations in the S&P 500 Index, selected and weighted using a proprietary quantitative model that emphasizes financial strength, cash flow, and pricing power. The fund is non-diversified and may invest a higher percentage of assets in individual issuers than a diversified fund, so changes in the value of a single investment could cause greater fluctuations in share price.

How it has done
USMC share class · total returns with dividends reinvested
Volatility over the last 12 months: 12.93%. Past returns are a record, not a forecast.
Jun 2026 has been filed since the trailing figures were struck, so it is not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
