Martingale Asset Management names co-CEOs

James "Mac" Eysenbach and Jennifer Cooper were named co-CEOs of Martingale Asset Management, a Boston-based quantitative equity boutique with more than $4.8 billion in assets under management as of June 30.

Eysenbach, Martingale’s chief investment officer, and Cooper, the firm’s chief financial officer and chief compliance officer, took over the co-CEO roles from Martingale co-founder Bill Jacques, effective July 1.

Jacques said the passing of the torch simply recognized what has been a successful transition at Martingale over the past five or six years.

Jacques, meanwhile, said he’s taking on the title of co-chair of the board of directors, joining co-chair Alan Strassman, and will remain an active member on Martingale’s investment team.
