Indeed. Mary Buffetts Buffettology was criticized by Buffett for being too formulaeic which was not his approach.

Thus said, it may well be possible that this sort of formula works, or achieves good results. At least for some time.

But then again, Joel Greenblatts 'magic' formula is just as good and doesn't require such a high subscription fee. In fact, apart from the book it's entirely free. If that professor has a 'genetic' urge to teach, then why doesn't he make his teachings more accessible like millions of others have done before him?

I'd stay on the side lines. Unless someone is able to travel faster than light I cannot see how they can reliably predict the future --which is what investors try to do.
