GAM has confirmed Andrew Green will step back as lead portfolio manager on several funds as Adrian Gosden becomes co-manager of the UK Diversified fund.
Chief executive Alexander S Friedman described Green as a “legendary” investor with nearly 50 years experience in the finance industry.
Green also leaves behind the Global Diversified fund, which will be managed by Ali Miremadi from 1 January. Gosden will co-manage the UK Diversified fund with Chris Morrison.
Gosden is also preparing to launch a new UK equity income product later this year after joining GAM last month.
Green will manage a “select few” mandates and provide advice and support to GAM equity teams in the new role of director of global equities strategy.
Friedman says: “He is universally lauded as an outstanding and disciplined investor, a status underscored by numerous awards and accolades throughout his career.
“His investment philosophy has helped to create GAM’s conviction-led culture, forming one of the core principles on which our brand is built today.”
Green says he joined GAM when it was first founded in 1983 by Gilbert de Botton, father of famous British philosopher Alain.
“Gilbert’s entrepreneurial spirit and innovative approach to meeting clients’ needs through active management are still at the core of GAM’s DNA,” says Green.
He says he looks back fondly on his 34 years with the company and looks forward to working with GAM in an advisory capacity.
