Two former investment bank traders have quit Brevan Howard

Two more former investment banking traders who left for a role at Brevan Howard have left the hedge fund in recent weeks as it struggles to maintain performance.

Mark Deniston, a former managing director and head of sterling rates swaps at Goldman Sachs, left Brevan Howard earlier this month, according to filings on the Financial Conduct Authority register. He joined Brevan Howard as a partner in 2013, when a number of senior banking traders were making moves to the buy-side.

His exit follows that of James Watson, the former head of swaps trading at Morgan Stanley who joined Brevan Howard in 2011 and was later promoted to partner. He left in May and is still on gardening leave.

Meanwhile, Robin Pollock, another partner who joined from Citigroup in 2004, also left in July, regulatory filings suggest.

The latest exits are reflective of tough times at Brevan Howard, which is in the midst of its third down year. Its UK partnership currently has 66 registered employees, down from 73 at the beginning of 2016 and 89 at this point last year.

Adrian Hilton, a portfolio manager at Brevan Howard for nearly eight years, left the hedge fund in March and has since re-emerged at Columbia Threadneedle Investments. This marks a return to long-only asset management, as Hilton joined from Aberdeen Asset Management in 2008.

James Fauset, a former Goldman Sachs managing director and an FX portfolio manager at Brevan Howard, left in January and is now head of FX agency at Coex Partners.

In April, Brevan Howard hired David Ghosh as a portfolio manager from UBS, where he was a managing director and GBP/inflation rates trader.
