GuideStone Funds Equity Index Fund (GEQYX) is a passively managed open-end mutual fund that seeks to approximate the price and dividend performance of the S&P 500 Index by investing substantially all, and normally at least 80%, of its total assets in the equity securities, primarily common stocks and stock index derivatives, included in the S&P 500 Index, in weightings that mirror the index's relative composition; it may invest to a lesser extent in derivative instruments, including exchange-listed options, futures and swap agreements. The fund, part of the GuideStone Funds family--the nation's largest faith-based mutual fund complex with approximately $18.9 billion in assets under management as of June 30, 2024--belongs to the Large Blend category and is available to institutional investors with a minimum initial investment of $1 million, featuring a net expense ratio of 0.12% and daily pricing. GuideStone Funds operates under GuideStone Capital Management, LLC, the investment adviser and a controlled affiliate of GuideStone Financial Resources of the Southern Baptist Convention, founded in 1918 and headquartered in Dallas, Texas, serving over 250,000 members and 24,000 ministry partners nationwide with retirement, insurance, investment and related financial services aligned with evangelical Christian values. Launched on August 27, 2001, GEQYX has grown to manage total net assets of about $5.52 billion, with its share class at roughly $3.95 billion. In recent developments, GuideStone Funds announced plans in 2025 to terminate and liquidate the Impact Equity Fund (GMEZX), with final liquidation scheduled for July 25, 2025, reflecting ongoing portfolio optimization amid its manager-of-managers approach that combines strategies from multiple investment firms; additionally, GuideStone Investment Services secured an outsourced chief investment officer mandate in October 2025 from WatersEdge, managing over $500 million in assets, while the broader organization continues expansions like enhanced Mission:Dignity support and pastoral wellness initiatives.
