GMO Risk Premium Fund Class III (GMRPX) is a mutual fund managed by Grantham, Mayo, Van Otterloo & Co. LLC (GMO), a Boston-based global asset management firm founded in 1977, that seeks to generate total returns over the long term commensurate with those of global equity markets with lower volatility primarily by writing put options on U.S. and non-U.S. stock indices; the strategy captures the equity risk premium and variance risk premium through systematic option selling on major equity indices such as the S&P 500 and global benchmarks, collecting insurance-like premiums while maintaining equity-like exposure without direct ownership of stocks. The fund invests in a non-diversified portfolio that may include exchange-traded funds (ETFs), mutual funds tracking equity indices, repurchase agreements, and derivatives including options on indices, futures, and swaps to implement its put-writing approach and manage collateral; it does not target or benchmark against specific securities indices, emphasizing capital preservation and appreciation over full market cycles. Headquartered in Boston with additional offices in London, San Francisco, Singapore, Sydney, Tokyo, and Amsterdam, GMO oversees approximately $78 billion in assets across various strategies for institutional and high-net-worth clients worldwide.
Recent developments include the election of Enrique Chang as an independent Trustee of GMO Trust, the entity offering GMRPX, at a special shareholder meeting on September 9, 2025, supplementing the board amid ongoing governance reviews. GMO Trust issued a semi-annual report as of August 31, 2025, detailing portfolio holdings such as repurchase agreements with Nomura Securities International, Inc., reflecting stable operational liquidity management. No major partnerships, acquisitions, funding rounds, product launches, or strategic shifts specific to the Risk Premium Fund were reported in 2024 or 2025, with GMO maintaining its core valuation-driven, contrarian investment philosophy across funds amid quarterly market commentaries.
