'The most explosive, mind-blowing business book I've ever read' – Bradley Hope, New York Times bestselling author of Billion Dollar Whale 'Jaw-dropping . . . well-told, well-structured and exquisitely reported' – Financial Times Discover the unauthorized, unvarnished story of famed Wall Street hedge-fund manager Ray Dalio. Ray Dalio is the billionaire founder of Bridgewater Associates, the world's largest hedge fund. In The Fund, Rob Copeland draws on hundreds of interviews with those inside and around the firm to reveal what really goes on with Dalio and his cohorts behind closed doors. Tracing more than fifty years of Dalio's leadership, The Fund peels back the curtain to reveal a rarefied world of wealth and power, where former FBI director Jim Comey kisses Dalio's ring, recent Pennsylvania Senate candidate David McCormick sells out, and countless Bridgewater acolytes describe what it's like to work at this fascinating firm. When Dalio announced in October 2022 that he was stepping down from the company he founded forty-seven years ago, the news made headlines around the world. Dalio achieved worldwide fame thanks to a mystique of success cultivated in frequent media appearances, celebrity hobnobbing, and his bestselling book, Principles. Dalio has stepped down from Bridgewater before; will the legacy of his Principles continue to chart the course of the firm? The Fund provides unique insight into the story of Dalio and Bridgewater, past, present and future.
