The former co-head of fixed income at Gartmore, and one of the best known bond managers in London, has resurfaced at a hedge fund less than a year after he left the UK investment group.

Karl Bergqwist, who exited Gartmore in December last year as part of restructuring of the firm, has joined Arrowgrass Capital Partners, a multi-strategy hedge fund founded by a team of former proprietary convertible bond traders at Deutsche Bank.
