- iShares S&P 500 Index Fund Investor A Shares (BSPAX) is an open-end mutual fund managed by BlackRock that seeks to provide investment results corresponding to the total return performance of the S&P 500 Index by investing substantially all of its assets in a master portfolio that holds the same securities and in the same approximate proportions as the benchmark index. The fund offers Investor A shares with a net expense ratio of 0.35%, a minimum initial investment of $1,000, and subsequent investments of $50, featuring daily pricing and no front-end or deferred loads. It primarily invests at least 90% of its assets in large-cap U.S. equities comprising the S&P 500, with top holdings including NVIDIA Corporation (7.35%), Apple Inc. (7.04%), Microsoft Corporation (6.22%), Alphabet Inc. (5.71%), and Amazon.com Inc. (3.85%), providing diversified exposure across technology (34.39%), financial services (13.67%), consumer cyclical (10.54%), communication services (9.80%), and healthcare (9.34%) sectors.
Launched on April 10, 2013, and domiciled in the United States, BSPAX operates within the large blend category and targets retail and institutional investors seeking core equity market exposure, with total net assets exceeding $49.92 billion and Investor A share class assets at $3.35 billion as of recent data. The fund is headquartered with BlackRock Funds III in the U.S., specifically associated with BlackRock Fund Advisors at 55 East, and remains available for sale exclusively in the United States. Geographically, its portfolio is overwhelmingly U.S.-focused (99.55% U.S. stocks), with minimal non-U.S. exposure (0.51%).
Portfolio management includes longstanding manager Jennifer Hsui (since April 8, 2016) alongside recent additions Peter Sietsema, Matt Waldron, and Steven White (all effective April 1, 2025), reflecting a strategic team expansion to enhance oversight of the index-tracking approach. No major acquisitions, funding rounds, partnerships, or product launches specific to BSPAX were reported in 2024 or 2025; however, BlackRock continued broader iShares expansions, such as the July 2025 launch of the iShares Infrastructure Active ETF and other active ETFs, alongside routine prospectus updates effective June 30, 2025. The fund maintained its passive strategy amid market volatility, delivering a 2024 total return of 24.54% for Investor A shares, closely tracking the S&P 500's 25.02%.
