Rydex S&P 500 H (RYSPX) is a mutual fund offered by Rydex Funds, managed by Guggenheim Partners, that seeks to provide investment results that match the performance of the S&P 500 Index before fees and expenses; it employs a replication strategy by investing at least 80% of its net assets in securities comprising the benchmark index, including common stocks, depositary receipts, and securities convertible into common stocks. The fund offers class H shares characterized by a high initial sales load of up to 4.75%, a 1% contingent deferred sales charge on redemptions within one year, and an expense ratio typically around 1.65%, targeting long-term investors seeking broad U.S. large-cap equity exposure with leveraged or inverse alternatives available in the broader Rydex lineup. Rydex Funds operates primarily in the United States, with administrative headquarters in Chicago, Illinois, as part of Guggenheim Partners' asset management division founded in the late 1990s to provide specialized index-based and sector-focused investment products. In recent developments, Guggenheim Investments has expanded its Rydex variable annuity series integrations and announced enhancements to ETF offerings mirroring S&P 500 strategies in 2024, alongside strategic partnerships for sustainable investing mandates amid market shifts toward ESG-aligned index tracking.
