Jack Gray, global strategist at GMO Australia, will return to the funds manager’s Boston headquarters in March to take up a co-director of asset allocation role.

Gray, who rejoined long-term employer GMO in 2005 after a stint as Sunsuper’s chief investment officer, will spend about 8 months a year in Boston and the balance in Sydney under the new arrangement. According to GMO’s head of client service, Kerri Pratt, Gray’s new role would allow him to focus solely on asset allocation, without some of the client-facing responsibilities of his current role. There was no need to replace Gray, Pratt said, because he had technically always been employed by the Boston office.
