The individual investor should act consistently as an investor and not as a speculator. This means... that he should be able to justify every purchase he makes and each price he pays by impersonal, objective reasoning that satisfies him that he is getting more than his money's worth for his purchase.Benjamin Graham
"Benjamin Graham" (; May 8, 1894 – September 21, 1976) was a British-born American professional stock investor/investor. Graham is considered the father of value investing, an investment approach he began teaching at Columbia Business School in 1928 and subsequently refined with David Dodd through various editions of their famous book Security Analysis (book)/Security Analysis. Graham had many disciples in his lifetime, a number of whom went on to become successful investors themselves. Graham's most well-known disciples include Warren Buffett, William J. Ruane, Irving Kahn and Walter J. Schloss, among others. Buffett, who credits Graham as grounding him with a sound intellectual investment framework, described him as the second most influential person in his life after his own father. In fact, Graham had such an overwhelming influence on his students that two of them, Buffett and Kahn, named their sons Howard Graham Buffett and Thomas Graham Kahn after him. Graham also taught at the UCLA Anderson School of Management.If you enjoy these quotes, be sure to check out other famous economists! More Benjamin Graham on Wikipedia.
