Edward M. "Ted" Maloney will become chief investment officer of MFS Investment Management on Jan. 1.
He takes the title from Michael W. Roberge, who will remain CEO, confirmed Jon Brubaker, a company spokesman.
Mr. Maloney will retain his role as global director of research and will join the firm's management committee. He will report to Mr. Roberge.
Mr. Maloney joined MFS in 2005 and "brings extensive experience to the role having held multiple investment research positions at the firm," said Mr. Roberge in a news release, adding "he has worked across the equity, fixed-income and quantitative groups to build strong, collaborative relationships that will serve him well as CIO."
As CIO, Mr. Maloney will oversee an investment team numbering more than 200.
