What the fund is made of
Percentages are of fund net assets. Rounding, liabilities and short positions can make totals differ from 100%.
| Stocks | 99.79% |
| Cash & short-term | 17.02% |
| Derivatives | 0.00% |
| Other | 0.00% |
These positions come to 116.82% of the fund's net assets. This counts only what the fund reported holding — the holdings disclosure covers assets, not liabilities such as borrowings — so it is not expected to reconcile to 100%.
Derivatives are shown at market value, not notional exposure.

How it has done
IWM share class · total returns with dividends reinvested

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.
