At Bellerphon Mr Lee's focus was on global fixed income strategies, including relative value trades, calendar spreads, cross-market spreads, curve trades and option structures.

Prior to this, Mr Lee worked for West End Capital Management in Bermuda, with a similar mandate in US and global fixed income markets. Before that he spent five years in London, first as a proprietary trader with Yamaichi International and then as a senior trader with Medici Trader Management, where he gained a wide range of experience in relative value trading in global fixed income markets.

Jeremy Hale, lead manager on Gartmore's Global Macro Fund, said: "David's track record in fixed income markets, particularly in relative value trading, will complement and add impetus to the current, more directional orientation of the Macro Fund. His appointment underpins our commitment to the Global Macro Fund and fixed income in general."
