Amaranth's Natural Gas Gambler Mr Hunter - A 2nd Nick Leeson

Amaranth's assets had swollen to $9bn at their peak a month ago, making it one of America's most influential hedge funds, with all the usual trappings of the industry, including plenty of luxuries for employees, including a private recording studio at its Connecticut headquarters where traders can relax by jamming on the company's guitars.

The fund's success in the past 18 months came largely because of ballsy and successful bets in the energy market by Mr Hunter. But Mr Maounis faces questions over how he allowed Mr Hunter to put so much of the fund's capital at risk, particularly since the trader already had a reputation as an aggressive risk-taker. He is currently suing his former employer, Deutsche Bank, for removing him from their trading desk and denying him a bonus after he racked up losses there.
