GMO

GMO's investment decisions are led by a team of portfolio managers, with Ben Inker and Tom Hancock co-heading asset allocation. Jeremy Grantham serves as Long-Term Investment Strategist, providing macro commentary. The firm's quantitative models are designed by a large research team, with oversight from the investment committee.

GMO uses a proprietary quantitative framework that screens global markets for value, quality, and sentiment anomalies. Ideas emerge from systematic models rather than discretionary stock-picking, with the firm's edge in long-term horizon analysis and contrarian positioning. The approach has been publicly detailed in white papers and commentary (per the firm).

Jeremy Grantham co-founded the Grantham Foundation for the Protection of the Environment, separate from GMO. The foundation supports climate and biodiversity initiatives, with Grantham's philanthropic identity distinct from his role at GMO. The two entities operate independently.

GMO avoids high-growth, low-quality, and heavily speculative sectors, particularly those trading at extreme valuations. It has historically steered away from technology stocks during bubble periods, and generally does not invest in private markets, commodities, or currencies.
