Brandon Haley, head of global equities at Ken Griffin's Citadel, left after nine years at the hedge fund firm.
Mr. Haley was the sole head of the group following the departures of Steve Weller in February 2013 and Jeff Runnfeldt in August 2012. Executives in New York, Chicago, San Francisco and London will oversee the business, and will report to Mr. Griffin, founder of the $24 billion firm, said Katie Spring, a spokeswoman for Citadel. Mr. Haley, who left this month, didn't return e-mails seeking a comment.
Citadel has two equity teams. The group Mr. Haley ran is mainly made up of home-grown talent — people who join the firm after college. The second, called Surveyor Capital, is composed of experienced managers who run their own teams with support and backing from Citadel. Last year, Tim Schneider, Peter Avellone and Shoney Katz all joined Surveyor Capital from Steve Cohen's Point72 Asset Management.
Mr. Haley had headed the global equities team since 2009. Before joining Citadel in 2005, he worked at North Sound Capital and Goldman Sachs Group.
