Mark Sanborn, former managing director in equities at Lehman Brothers in New York, has resurfaced at hedge fund giant Highbridge Capital Management, which manages over USD4.5 billion in assets. Sanborn, reached at the firm, said that he was working in "connection" with the fund manager, but denied having "joined" Highbridge. Sanborn is also listed with the firm on Bloomberg. He declined to elaborate. Glenn Dubin, co-founder at Highbridge in New York, did not return calls.
Some officials familiar with Sanborn speculated that he might be working as a consultant to the hedge fund and be subject to a non-compete clause with Lehman, having only left the firm in August (DW, 8/31). Others pondered whether Highbridge is backing Sanborn in a venture of his own. Highbridge ranks as the world 25th largest hedge fund manager according to Institutional Investor.
Sanborn worked at Lehman for eight years and is mainly known for having a sales background, although at Lehman he also managed a trading desk, noted one official familiar with his career. Posts he held at Lehman included co-head of equity derivatives as well as global head of program trading.
