About MMIEX

The MASSMUTUAL SELECT FUNDS: MM S&P 500® Index Fund Service Class is an open-end mutual fund designed to closely track the total return of the S&P 500 Index. As an equity fund, it primarily invests at least 80% of its assets in the common stocks of large-cap U.S. companies listed in the S&P 500, providing broad exposure to leading sectors like technology, consumer discretionary, and financials. The portfolio generally mirrors the composition and sector weights of the index, with top holdings often including widely recognized firms such as Apple, Microsoft, and Amazon. This fund aims to replicate the performance of the benchmark index by adopting a passive investment approach, making it suitable for investors seeking diversified exposure to the overall U.S. stock market within a single investment vehicle. Its low expense ratio, transparent structure, and annual dividend distributions contribute to its appeal for long-term investors focused on growth and market representation. Managed by MassMutual, it supports retirement plans and individual investors looking to participate in the growth of major U.S. companies while benefiting from the cost efficiency typically associated with index funds.
