There has been a shakeup at the top of one of billionaire Ken Griffin's stock-picking units.
Rich Schimel, who headed Aptigon, a unit of $27 billion hedge fund Citadel, and David Bonfili, formerly Aptigon's COO, have left, a spokesman for Citadel confirmed in an email to Business Insider.
"Eric Felder has been named Head of Aptigon Capital and Reza Shahi will assume COO responsibilities for the business," the spokesman said.
Felder joined Citadel last May to launch the Fundamental Strategies unit, and later took on the firm's Global Credit business, per the spokesman. Felder will continue with these roles in addition to heading Aptigon.
The departures mark a sharp turnaround for Aptigon, which launched in 2016 with Schimel at the helm. At the time, Schimel went on a hiring spree from fallen rival Visium Asset Management, bringing on 17 portfolio managers for the unit, the Wall Street Journal reported at the time.
The spokesman added that Citadel has "parted ways" with several other Aptigon investment staffers, but did not say who.
The spokesman said: "We are committed to the success of Aptigon Capital, and we will continue to recruit leading talent to the team."
