GMO

GMO is bound up with Jeremy Grantham, its co-founder and one of the most quoted bubble-callers in market history. The firm built its reputation on a long-term, valuation-based philosophy and publishes open-access seven-year asset-class return forecasts that circulate widely through investment research. Grantham has pledged the bulk of his ownership to environmental philanthropy.

Founded in Boston in 1977, GMO is controlled by its active employee-members, with no single member holding more than fifteen percent. It organizes around specialized teams in global, emerging-markets, and quality equities, fixed income, and multi-asset strategies, and is known for taking contrarian positions when its valuation work points that way.
