Martin Whitman, a legendary value investor, passed away on 16th April. He was the founder of Third Avenue Management. Marty, as he was better known as, was a passionate value investor and a teacher. He was associated and took classes at Syracuse University’s Whitman School of Management, named after him. He was a distinguished Management Fellow at the Yale School of Management and served as an adjunct professor at Columbia University Business School.
I first became aware of him about 15 years back, from a talk given by Seth Klarman, where Seth suggested reading Marty's book "The Aggressive Conservative Investor". I read the book and it was packed with a lot of good and simple insights. Two ideas that stuck with me were, i) buying companies with low margins because of low competitive intensity and ii) mean reversion of sectors.
