The Little Book of Value Investing (2007) by Christopher H. Browne
This book provides a thorough but concise overview of value investing, which is the approach of buying undervalued stocks of good companies. The author provides many useful and sensible pieces of advice for identifying candidates for investment and avoiding bad companies that are trading cheaply. He also presents evidence from recent studies that supports his claims about the long-run success of value investing. The book is written for the layperson, making it a quick and easy read. Although I have incorporated some elements of value investing into my existing investment strategy, there were certain points made in this book that helped to inform and strengthen my strategy.
Note: I read this book in November 2011.
