John Arnold

Energy-trading prodigy John Arnold had never had a down year before 2010.

Since he launched his hedge fund, Centaurus in 2002, he managed an annual growth rate of about 125% and stellar returns.

People close to Centaurus say it was not [Arnold] but one of his traders who drove returns into the red with a bullish natural gas bet that dragged down the fund’s performance.
