When Genius Failed: The Rise and Fall of Long-Term Capital Management

Meriwether & Co. truly believed that their finely tuned computer models had tamed the genie of risk, and would allow them to bet on the future with near mathematical certainty. Thanks to their cast - which included a pair of future Nobel Prize winners - investors believed them. Four years later, when a default in Russia set off a global storm that Long-Term's models hadn't anticipated, its supposedly safe portfolios imploded. In five weeks, the professors went from mega-rich geniuses to discredited failures. The firm's staggering $100 billion balance sheet threatened to drag down markets around the world. At the eleventh hour, fearing that the financial system of the world was in peril, the Federal Reserve hastily summoned Wall Street's leading banks to underwrite a bailout.

Best selling author Roger Lowenstein captures Long-Term's roller-coaster ride in gripping detail. Drawing on confidential internal memos and interviews with dozens of key players, Lowenstein crafts a story that reads like a first-rate thriller from beginning to end. He explains not just how the fund made and lost its money, but what it was about the personalities of Long-Term's partners, the arrogance of their mathematical certainties, and the late-90s culture of Wall Street that made it all possible.
