The Piotroski F-Score is a nine-criteria scoring system developed by financial academic, Joseph Piotroski. It’s aim is to identify companies which are improving their financial position in performance. This is measured on a TTM basis.
Piotroski first published his now well known ratio in a this famous research paper.
Companies with a score of 8 or 9 have been found as a group to outperform weak stocks by 7.5% annually over a 20 year period.
The weakest stocks, scoring 2 or lower, were found by Piotroski to be five times more likely to fall into financial problems.
Adding to this, he found in his paper that for groups of companies with high F-Scores, the entire distribution of returns was shifted to the right, successfully eliminating many of the worst losers from the group of stocks.
