S eth Klarman is a highly respected American billionaire investor and hedge fund manager, often referred to as the 'Oracle of Boston.' He is the chief executive and portfolio manager of the Baupost Group, a private investment partnership he co-founded in 1982. A devout follower of the value investing philosophy pioneered by Benjamin Graham, Klarman is known for his patient, risk-averse, and often contrarian investment approach. He seeks out complex and misunderstood situations, investing in a wide range of assets, including distressed debt, real estate, and publicly traded stocks that are trading below their intrinsic value.

Klarman's disciplined strategy has generated exceptional long-term returns for his investors while prioritizing capital preservation. He is also the author of the highly sought-after book, 'Margin of Safety: Risk-Averse Value Investing Strategies for the Thoughtful Investor.' Published in 1991, the book has become a cult classic in the investment world, with out-of-print copies selling for thousands of dollars. Despite his immense success, Klarman maintains a relatively low public profile, preferring to communicate through his annual letters to investors, which are closely read for their insights on markets and risk. He is also a significant philanthropist and has owned a major stake in the horse racing industry.
