Title: The Intelligent Investor
Content:  Benjamin Graham is regarded as the father of value investing and The Intelligent Investor was highly regarded by the public and remains so. Ronald Moy, professor of economics and finance at St. John’s University, explains that “The influence of Graham's methodology is indisputable. His disciples represent a virtual who's who of value investors, including Warren Buffett, Bill Ruane, and Walter Schloss”. Warren Buffett is regarded as a brilliant investor and Graham’s best-known disciple. According to Buffett, The Intelligent Investor is “By far the best book on investing ever written.” Ken Faulkberry, founder of Arbor Investment Planner, claims, “If you could only buy one investment book in your lifetime, this would probably be the one”. Many of Graham’s investment strategies explained in the book remain useful today despite massive growth and change in the economy. Scholar Kenneth D. Roose of Oberlin College writes, “Graham’s book continues to provide one of the clearest, most readable, and wisest discussions of the problems of the average investor”. The Intelligent Investor was received with praise from economic scholars and everyday investors and continues to be a premier investing book today.
