Fund profile
As filed in the prospectus · 2026 Q2
The fund seeks to match the total return of the S&P 500 Index.
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.

Portfolio growth profile
How much of the fund’s stock holdings are in fast-growing companies · as of 2026 Q2
Share of the fund’s equity (by value) in companies whose trailing five-year revenue — or net-income — growth ranks in the top 25% of U.S. public companies. Foreign and newly-listed holdings are excluded, so the figure covers only part of the book. From SEC filings — not investment advice. How we measure this.

Return profile
Total return as filed — price change plus distributions reinvested · trailing figures to 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.
