Kevin Turner, chief executive officer of hedge-fund Citadel LLC's electronic market-making unit, has stepped down after joining the firm less than a year ago from Microsoft Corp.

Peng Zhao, who is vice chairman of Citadel LLC, has been named the new head of the Citadel Securities unit. A spokesman for Citadel confirmed the changes in an email.

"I want to thank Kevin Turner for his leadership and the lasting impact he made on our firm," billionaire Kenneth Griffin, founder and CEO of Citadel, said in the email.

Mr. Turner was previously Microsoft's chief operating officer before he left to head Citadel Securities in 2016, according to a Wall Street Journal article in July. Before joining the software giant, he was information chief at Wal-Mart Stores Inc. and head of the retailer's Sam's Club warehouse club, according to the article.

Mr. Zhao has been at Citadel since 2006 and has also worked as the global head of market making for Citadel Securities, according to the email.
