ASSESSMENT OF EFFICIENCY OF PIOTROSKI F-SCORE STRATEGY IN THE WARSAW STOCK EXCHANGE

Summary/Abstract: Piotroski F-score is a strategy applied to the stock exchange that integrates the analysis of financial signals into the so-called investing in value. The aim of the article is to evaluate the efficiency of Piotroski F-score on the example of the Warsaw Stock Exchange in period 2014–2020. The legitimacy of addressing this subject results from the insufficient amount of research conducted so far. There are very few analyzes of the F-score strategy both in Poland and in foreign markets. The article presents the results of applying Piotroski F-score to the WIG30 index in order to verify whether the strategy leads to an increase in the rate of return on investment in value companies. The study confirmed that analysis of financial statements as an additional stage of value investing can provide the investor with higher returns. It has been also proved that the F-score strategy is more efficient than simple investing in the WIG30 index. Portfolios with high F-score companies appeared to be more efficient than portfolios including only low Fscore firms.
