Fund profile

As filed in the prospectus · 2026 Q2

The fund seeks to match the total return of the S&P 500 Index.

Strategy · summarised

The fund holds all 500 stocks in the S&P 500 Index in proportion to their market-capitalization weights, with the aim of tracking the index's total return. Because the fund carries expenses, its performance will lag the index slightly. The fund is non-diversified to the extent the S&P 500 Index itself is non-diversified, and may concentrate up to 25% or more of assets in a single industry or sector in line with index weightings.

Cumulative return· Jul 2023 – Apr 2026

May 2026 and Jun 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.

This fund changed legal form during the period shown. The history above is continuous — it spans both eras, and the change is not a gap in reporting.
