Rydex NASDAQ-100 Fund (RYCOX) is an open-end mutual fund that seeks to provide investment results corresponding to the performance of the NASDAQ-100 Index before fees and expenses. The fund employs a replication strategy to invest at least 80% of its net assets in securities of the underlying index and in depositary receipts representing securities of the index; it may also utilize derivative instruments such as swap agreements, futures contracts, and options on futures for exposure, hedging, or risk management. It offers daily liquidity to investors through share redemptions at net asset value, with no load structure and a focus on large-cap growth equities primarily in technology, consumer discretionary, and communication services sectors.
Established in 2001 and managed by Rydex Advisors, LLC, a subsidiary of Guggenheim Partners, LLC headquartered in Chicago, Illinois, the fund operates globally through its exposure to U.S.-listed securities of multinational companies, targeting institutional and retail investors seeking NASDAQ-100 benchmark performance. Its portfolio typically holds around 100-110 positions mirroring the index's composition, including major holdings like Apple Inc., Microsoft Corp., and NVIDIA Corp., with an emphasis on non-financial growth stocks. The fund maintains a low turnover rate aligned with index reconstitution and provides detailed holdings, performance metrics, and risk disclosures via regulatory filings.
In recent developments, the Rydex family of funds, including RYCOX, underwent a strategic rebranding and integration under Guggenheim Investments following the 2021 acquisition of Rydex by Guggenheim Partners, enhancing distribution channels and operational efficiencies. In 2024, the fund benefited from expanded ETF offerings in the Rydex/Guggenheim lineup, including leveraged and inverse variants tied to the NASDAQ-100, alongside a shift toward enhanced tax-efficiency through securities lending programs. No major mergers, liquidations, or performance-altering changes were reported in 2025, though ongoing portfolio adjustments reflect NASDAQ-100 quarterly rebalances amid AI-driven market rallies.
