When Genius Failed: The Rise and Fall of Long-Term Capital Management by Roger Lowenstein, which tells the story of the hedge fund Long-Term Capital Management (LTCM), its meteoric rise, and its spectacular fall. The book explores how LTCM's founders, including renowned academics and former Salomon Brothers traders, employed complex financial models and leveraged bets to generate impressive returns for years, but ultimately made devastatingly risky bets that caused the firm to collapse. The book also examines the role of Wall Street banks, the Federal Reserve, and regulatory oversight in LTCM's success and failure, arguing that the firm's downfall exposed flaws in the financial system, and ultimately led to a broader reckoning in the world of finance.
