Kenneth Griffin's hedge fund firm Citadel Investment Group is in advanced talks to hire Jake Walthour, co-founder of Aksia LLC, the Wall Street Journal said, citing people familiar with the matter.
The paper said talks of the move have been circulating among investors and hedge-fund consultants over the past few days.
Walthour left Aksia, a New York-based investment-consulting firm, in December, according to the paper.
Citadel could not be immediately reached for comment by Reuters outside regular U.S. business hours.
Kenneth Griffin, long considered one of the industry's best managers, delivered gains of 62 percent to investors in Citadel's flagship Kensington and Wellington funds in 2009, an investor told Reuters in December.
