The former head of markets at Barclays, who left the bank in April, is set to join hedge fund Magnetar Capital, an Illinois-based hedge fund firm which has just sold a stake in itself to Blackstone Group.

Eric Felder, a 21-year veteran of both Barclays and Lehman Brothers before his departure, will join the firm as a partner based in New York, according to a statement issued by the company Friday afternoon.
