Piotroski F-Score for WisdomTree Commodity Securities Limited - WisdomTree Copper 1x Daily Short - Preferred Security
In 2000, Joseph Piotroski published a paper titled "Value Investing: The Use of Historical Financial Statement Information to Separate Winners from Losers." This paper described a method of using data from a company’s financial reports to help predict future performance.
The Piotroski F-Score, as it is known, is a 9-point discrete score, where 9 is the best, that ranks companies based on a number of financial factors. To calculate the score, we compare nine factors from the two most recent annual reports. If the change in the factor is "good", then we add one to the score. If the change in the factor is "not good", then we add zero. The following explanations are quoted from the paper.
