Simon Finch, who manages about $3 billion for CQS Investment Management in London, is leaving the hedge fund, according to two people familiar with the matter, who asked not to be identified because the information is private.
As CQS' chief investment officer for credit, he manages the firm's Credit Multi Asset fund, one of the largest held by the $12 billion hedge fund run. The long-only fund was up 5.2% through August after gaining 3.6% in 2015, according to investor letters seen by Bloomberg.
Michael Rummel, a spokesman for CQS, declined to comment on the departure. Mr. Finch didn't reply to calls and e-mails seeking comment.
Mr. Finch is the latest in a string of employees to leave the firm this year. Simon Finn, who led a unit buying distressed debt in Europe, and foreign-exchange trader Christopher Callan, were among at least 12 people who have departed.
Mr. Finch has worked in asset management for more than 20 years. He first joined CQS in 2004 before spending about a year at Peloton Partners in 2007 and returned to CQS in 2008, according to his registration with the U.K.'s Financial Conduct Authority.
CQS trades asset-backed securities, credit, convertibles, loans and equities from offices globally including London, New York and Sydney, according to its website.
