We hear that Marcus Browning has left JPMorgan Chase for the second time. Browning started his career at JPM but left to join Merrill Lynch before eventually moving on to Citi. He left Citi in 2008 to try his hand on the buy-side at London Diversified Fund Management. He left the imploding fund about a year ago to return to JPMorgan (People moves: Browning heads home), where he joined the proprietary desk. But prop desks at US banks can’t be the most stable of places to work when Dodd-Frank hangs over everything. Talk is that Browning is destined to re-emerge on the buy-side at hedge fund BlueCrest. Neither JPMorgan nor BlueCrest would comment.
