The 60-year-old billionaire is also known for maintaining peak physical condition. ## Early Successes Ackman made his name in the 2000s by exposing MBIA's vulnerabilities and predicting Chipotle's rise. These contrarian investments helped Pershing Square outperform the S&P fivefold in its first decade. ## Major Losses The failed $1 billion Herbalife short and $4 billion Valeant Pharmaceuticals disaster marked Ackman's biggest setbacks. However, these were offset by prescient moves during the subprime crisis and COVID pandemic. ## Going Public Pershing Square's dual NYSE listing reflects Ackman's inspiration from Warren Buffett's Berkshire Hathaway model.
