Fund profile
As filed in the prospectus · 2026 Q2
The investment objective of the Fund (Fund or Master Fund) is to track the performance of the S&P MidCap 400 Index to provide long-term capital growth by investing in equity securities of medium capitalization-weighted domestic corporations.
The fund tracks the S&P MidCap 400 Index by investing substantially all its assets in the stocks that compose the index, weighted by market capitalization, and may also hold ETFs and cash to maintain correlation or facilitate rebalances and redemptions. The fund may employ financial futures to assist in replicating index performance. Because the fund may be invested in a non-diversified manner to the extent the index itself is non-diversified, concentration risk can arise from the index composition.

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.
