Seth Klarman is one of the smartest value investors in the world. He is the President of The Baupost Group, a Boston hedge fund with AUM in excess of $22 Billion. In 1991 he wrote the book Margin of Safety, Risk Averse Investing Strategies for the Thoughtful Investor. If you haven´t read it, I strongly suggest you do. Unfortunately it is out of print and the book sells for more than $1,000. A pdf version of the book can be found here.
Seth Klarman is not a big fan of interviews so this long interview with Charlie Rose is extremely valuable. Enjoy!
