To approximate the aggregate total return of a broad-based U.S. domestic equity market index.
The fund is managed by a subadvisor that seeks to approximate the total return of the S&P 500 Index by holding common stocks in the index and securities outside it that the subadvisor believes will behave similarly to the index as a group. The fund may also use futures, swaps, and ETFs to achieve this tracking objective. Because the fund incurs operating expenses and transaction costs while the index does not, its returns will typically lag the index.

How it has done
JAGMX share class · total returns with dividends reinvested
Volatility over the last 12 months: 13.14%. 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.
The 3 share classes hold the same portfolio
| Share class | Expense ratio | 1 year | 3 years | 5 years | Worst fall |
|---|---|---|---|---|---|
| 0.25% | +29.47% | +87.34% | +91.23% | -8.34% | |
| 0.30% | +29.40% | +87.04% | +90.73% | -8.34% | |
| 0.50% | +29.13% | +85.93% | +88.79% | -8.39% |
These classes hold the same portfolio, so the 2.44pp spread over 5 years is the cost difference between them — roughly 0.49pp a year — not a difference in what they own.
