The Piotroski F Score is certainly a number you want to consider when searching for investment opportunities. In other words an F1-score from 0 to 9 0 being lowest and 9 being the highest is a mean of an individuals performance based on two factors ie.

The Ohlson O-score is based on a linear factor model. Its the harmonic mean of two other metrics namely. If the ratio compared to the prior year is lower F score is 1 0 otherwise.
F Value is calculated using the formula given below. We owe our thanks to Pasi for his detective work in finding that the formula for calculating a companys F-score had changed from 2007 and for developing the new and improved code to calculate the F.
