Enron's stock price rose astronomically in the late '90s, buoyed by investor confidence in former CEO Jeffrey Skilling-and by earnings reports that seemed to show Enron's profits growing by leaps and bounds. But as we now know, those numbers were engineered by a man named Andy Fastow, Enron's chief financial officer at the time. In this episode, we take a look at Mr. Fastow and hear from the whistleblowers who exposed him and Enron's financial engineering. John Emshwiller is the host of this season of Bad Bets.
