I am a financial advisor and we run our portfolios based on the large amount of research done by Fama and French. If you would like to be able to read more about them, go to http Dimensional Fund Advisors: DFA Home, which is an institutional fund company that we use and is ran on his research. (he is actually a consultant and board member for them)

I have met Fama and been through his presentations, which are essentially a one week Phd crash course. He, obviously, is very intelligent and passionate about his nobel prize winning research. He even talks about how he has improved on it and how part of it was wrong.

It is amazing that investors can use this model and pay about 75% less in fees and outperform 90+% of the funds, yet now one knows about it. Why? Because it does not sell and create commissions.
