BT multi strategies head Al Clark has left the group six months after getting the top job.
Clark was anointed into the newly titled role in March following the departure of BT head of alternative investments Richard Keary.
The division encompasses the group's balanced and hedge fund products, exposure management and quantitative research.
Clark is believed to be heading to Singapore, to a yet unnamed manager.
Clark joined BT's investment management team from Macquarie Fund Management's domestic fixed interest division in 2006.
A BT spokesperson said the group was looking to appoint a successor by the end of this week and was talking to both internal and external candidates.
Earlier this moth BT chief executive Rob Coombe said the creation of a newly spun off BT would offer incentives, such as the provision of options, to existing and potential investment staff.
"It creates a compelling model that will attract new talent into this business," Coombe said at the time.
Australian shares portfolio manager Troy Angus also departed earlier this year.
