Citadel's Mazzella Is Leaving After Guiding Fixed Income

  • Mazzella helped structure fixed income trading strategies
  • John Naud will replace Mazzella when he leaves, Citadel said

Richard Mazzella, chief operating officer for global fixed income at Citadel LLC, is leaving the $25 billion hedge fund at the end of the month.

He worked with Citadel’s Wellington and Kensington funds, which returned 14.35 percent last year, according to data compiled by Bloomberg. Citadel was ranked as the top hedge fund of 2015 by Risk magazine. John Naud, a portfolio manager for U.S. fixed income, will replace Mazzella, said Zia Ahmed, a Citadel spokesman.

“We are grateful to Rich for his many contributions over the years and wish him all the best,” Ahmed said in an e-mailed statement.

Mazzella was previously the chief technology officer for global fixed income at JPMorgan Chase & Co., according to his profile on LinkedIn. Prior to that, he was chief operating officer in the bank’s global proprietary positioning and principal investing unit. He has a master’s degree from the Leonard N. Stern School of Business at New York University and holds an accounting degree from Lehigh University, according to the profile.

International Financing Review reported Mazzella’s departure earlier on Tuesday.
