Before one attempts to review "More Than You Know", it is useful to understand the author's background and context. Michael Mauboussin is Chief Investment Strategist of Legg Mason Capital Management. He is on the Board of Trustees of the Santa Fe Institute (SFI) and also teaches Security Analysis at Columbia Business School. Before Legg Mason, Michael was Chief U.S. Investment Strategist at Credit Suisse First Boston. During his career he has studied the objectives, resources and processes of successful investors; He has aggregated best practices of successful companies, competitive strategy, valuation and behavioral finance; He has studied the important principles of the major disciplines: Finance, Psychology, Mathematics, Physics, Philosophy, Biology, Evolution, History, Literature, Social Sciences. Michael has dedicated his career to one objective: The efficient and effective allocation of Financial and Intellectual Capital.
One of Michael's fundamental beliefs, also one of the main themes of "More Than You know", is that to succeed in accomplishing your investment and life objectives, you need to understand the most important principles of the major disciplines: Finance, Psychology, Mathematics, Physics, Philosophy, Biology, Evolution, History, Literature, Social Sciences. This belief is also a driving influence of Legg Mason's investment philosophy, SFI's culture and the Security Analysis class that Michael teaches at Columbia.
One of the barriers to learning the multi disciplinary approach to become a better investor and a better person is knowing how to properly filter the massive amounts of information (good and bad) that is out there. One of the ways to overcome these barriers is to find what I call filter/aggregators: someone with excellent judgment that has found the relevant knowledge, filtered it, and then aggregated the most important insights in one place for you. Examples of filter/aggregators in the investment world are: Bill Miller, Warren Buffett, Charles Munger and Michael Mauboussin. Michael's books (Expectations Investing, More Than You Know) and essays (Consilient Observer, Mauboussin on Strategy) are filled with investment insights, ideas from other disciplines that apply to investing and references to books, studies and essays by other authors.
The purpose of "More Than You Know" is to show how a multi-disciplinary approach to investing can improve investment skills by giving investors fresh perspectives. The book is divided in 4 Parts/Categories: Investment Philosophy, Psychology of Investing, Innovation and Competitive Strategy, Science and Complexity Theory. Each part is made up of about 7 essays that describe major ideas of each category. In the essays Michael uses examples from business, successful investors, other authors, and studies from other disciplines to derive investment insight. Michael gives an appropriate understanding of the insights. In the eventuality that the reader would like to dig deeper, the Notes section on the essays and the Reference section are filled with studies and books by Investors, Scientists, Physicists, Mathematicians, Biologist, ect...
The book is entertaining and provides knowledge that is very relevant to investors. It also makes you think since the perspectives it gives you are differentiated. One example: how studying fruit flies is relevant to the evolution of businesses within industries. Or how stock markets share many of the same features of social insect colonies such as ants.
It is important to observe how homogeneous the money management industry is. Mutual funds, brokers, individual investors, day traders all read the same newspapers, magazines, books; they have mostly two investment philosophies, value and growth; they read the same analyst reports; watch the same news channels. To accomplish your investment objectives and to gain an edge over the market it is necessary to have a differentiated point of view. "More Than You Know" gives you that differentiated perspective.
