I also read the interview – Joel Greenblatt’s Investing Secrets Revealed – Barron’s Oct 15, 2016. (Barron’s had also done previous articles on his formula – 2006, 2009, 2014.) After reading the Barron’s interview, I got a library copy of his updated book on The Magic Formula. Interesting concept, and thanks for putting it to work in Stock Rover. Your insights and caveats are also helpful.
