Recommendation

This book began as a series of 50 short essays Michael J. Mauboussin wrote for investors. He advocates using a multidisciplinary perspective to try to understand how markets behave. By its nature as a collection of essays, this book is capricious and desultory, jumping around from subject to subject. The essays do not necessarily relate to each other, but that has some advantages, given the author's belief in multiple analyses.

  • They are value investors and buy bargains.
  • Most are not based in New York or Boston.
