Anyway, I came across this excellent article, by Geoff that contrasts three formulaic investing techniques including Greenblatt's Magic Formula. I hope you enjoy it! Here is an excerpt and a link:
Is There Really A Magic Formula For Investing?
Geoff Gannon
This article looks at investing formulas proposed by three men: Benjamin Graham, David Dreman, and Joel Greenblatt. It then asks whether any of these formulas will lead to above market returns.
One question almost every investor asks at some point is whether it is possible to achieve above market returns by selecting a diversified group of stocks according to some formula, rather than having to evaluate each stock from every angle.
