High Piotroski Scores in Magic Formula Investing

Piotroski Score of '2' (Bad!):

Gentiva Health Services (GTIV)
Interpublic Group (IPG)
Lear(LEA)

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:

Dell(DELL) +15.2%
DeVry(DV) -30.6%
Visa(V) +60.8%
Mednax(MD) +26.6%
Buckle(BKE) +25.6%
Oshkosh(OSK) -37.1%
Aeropostale(ARO) -31.1%
Lincoln Educational Services(LINC) -37.0%
Nu Skin Enterprises(NUS) +68.1%
Seagate Technology (STX) +119.3%
Teradyne(TER) -7.2%
USA Mobility(USMO) -2.6%
Veeco Instruments(VECO) -36.0%

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.
