Chanos thought something was fishy with Enron's accounting practices after he started investigating the energy trading giant in 2002. He had some practice in short selling: Back in 1982, as a 24-year-old analyst, he had predicted the collapse of a piano maker-turned-financial-company called Baldwin United. His forecast with Enron was dead-on: Within months after he shorted the stock, the Houston-based company's share price fell. Chanos watched as the price plummeted on Enron's way to bankruptcy, from $90 to less than $1 in 16 months.
