A hotshot trader loses over $6 billion in a matter of a week. How can that happen? To understand how such loses can occur to both a successful trader and hedge fund, read Fooled by Randomness by Nassim Nicholas Taleb. This insightful book details how randomness is disguised as seemingly ordered events, leading to incorrect conclusions and decisions, as well as horrific loses.
Brian Hunter, the hedge fund's 32-year-old chief energy trader, was recently hailed as a rising star. What many thought was an innate ability to understand the market was simply a lucky run at the gambling table.
