I run this article at least once a year, and it is always interesting to see what the results actually are. Here are the one-year results of the Piotroski article from last February:
Lincoln Educational Services
Nu Skin Enterprises
As usual, a mixed bag of individual stocks, but again a solid result collectively. The average gain here is +10.3%, far outperforming the S&P 500's +6.2% performance over the same one-year period. We've seen good results using the Piotroski method as an additional filter on top of the Magic Formula® screens in the handful of times it has been tested.
As of the time of publication the author owned shares of UTHR.
