Every once in a while, the Muses conspire to change the things you do.

For years, when asked for a recommendation of an investment book, I responded that “Reminiscences of a Stock Operator” provided insights each time I read it.

The list is now longer. “More than You Know” by Michael J. Mauboussin has been added.

The author, in 50 insightful essays, draws from the latest in behavior economics and cognitive sciences to give the reader invaluable insights into the concepts of risk and choice.

His investment strategies are sound. They draw from creative thinkers as diverse as Warren Buffett and Steven Christ; they borrow from activities and fields as diverse as casino gambling and evolutionary biology.

Mauboussin believes a multidisciplinary approach based on process and psychology offers the best opportunity for long-term investment success. He breaks his book into four sections: Investment Philosophy, Psychology of Investing, Investment and Competitive Strategy and Science and Complexity Theory. Although his essays are insightful, he provides a thorough bibliography to guide future study.

Why the Muses moved to place this book in my hands last week, I do not know. But I am grateful they did. This book is a trove of knowledge and ideas. It is a must-read for anyone who takes their investing seriously. ( )
