Grantham, Mayo, Van Otterloo & Co (GMO) Portfolio holdings
Grantham, Mayo, Van Otterloo, known as GMO, is an asset manager with a contrarian, generally bearish outlook, betting that markets will drift back to their historical averages. Jeremy Grantham, Dick Mayo and Eijk van Otterloo founded it in 1977, after Grantham and Mayo had started Batterymarch Financial Management in 1969 and van Otterloo had worked alongside Grantham. It began as a conservative, value-oriented firm, and Grantham later used his number-driven background to build equity and bond funds that run on models and trade when prices stray from long-run norms. In 1994 GMO bought a fund that focused on defaulted bank loans, which became its Emerging Country Debt Fund, and in 2020 it acquired Usonian Investments, a Japan-based equity manager.
