Mr. Labitan has authored a wonderful addition to the value investing library. "The Four Filters" is today's "The Intelligent Investor" for the Grahem-Bufffett-Munger investing student. Mr Labitan's book lays out a clear, cogent, and concise case for Graham-Buffett-Munger investing that is the foundation of a successful investing career. "The Four Filters" equips an investor with an investing philosophy that will stand him/her in good stead during the inevitable market storms. The book is a rare combination of highly useful content and an enjoyable writing style. After finishing "The Four Filters" I hope that Mr.Labitan will follow it with the Graham-Buffett-Munger equivalent of Graham and Dodds "Security Analysis."
