Greg Coffey first appeared on an FN Rising Stars list in 2008, the same year that his departure from hedge fund GLG Partners sparked large outflows of assets from the firm and a sharp fall in its share price.

The emerging markets specialist, then 38, was estimated to have contributed about half of GLG's total $679m performance fees in 2007, according to sources. He had been expected to set up his own firm but a tough capital raising environment and a chance meeting withe Louis Bacon, the founder of Moore Capital, in the Curzon Street car park that the two hedge funds shared, saw him resurface at Moore in November of 2008.
