The fund tracks the CRSP US Large Cap Growth Index, but its portfolio has become top-heavy. As of June 5, 2026, NVIDIA accounted for 13.3% of the fund's assets, Apple for 12.3%, Google for 9.9%, and Microsoft for 9.1%. Analysis suggests that this makes the fund more like a portfolio dominated by semiconductor and platform companies, supplemented by investments in healthcare and payments, rather than a traditionally diversified index fund.
