Today’s conversation is with one of the finest intellectual investors and academic at heart, Michael Mauboussin. Michael is the Director of Research at BlueMountain Capital Management in New York and was formerly the Head of Global Financial Strategies at Credit Suisse and Chief Investment Strategist at Legg Mason Capital Management.
While rising to the top in his corporate career, Michael authored three books, including my favorite, More Than You Know: Finding Financial Wisdom in Unconventional Places, which was named one of the best business books by Businessweek and which features prominently in today’s show. Michael has been an adjunct professor of finance at Columbia Business School since 1993 and is on the faculty of the Heilbrunn Center for Graham and Dodd Investing. He is also Chairman of the Board of Trustees of the Santa Fe Institute, a leading center for multi-disciplinary research in complex systems theory.
On this episode, Michael and I talk about the early epiphany he had that set him on the path to Chief U.S. Investment Strategist, the importance of teaching value investing alongside psychology, the main contributors to investment bias, the importance of cognitive diversity, the top three techniques you can use to mitigate against bias in your investment processes, and so much more!
