Graham & Dodd Investing at Columbia University
This Columbia University page is an excellent summary of the research which shows that value investing works. These include the Browne, C.H., Browne W.H., Spears J.D., Shrager, T.H., & Wyckoff, R.Q. paper, 'What has Worked in Investing' and the impressive Andrew Dubinsky, “Value Investing Retrospective,” first published in 2006. Also included are articles by Fama and Lakonishok, J., A. Shleifer and R. Vishny, both mentioned in our Investment Charter.
