Since the metric is entirely based on financial statements, the scores are not consistent for all industries as the accounting standards and SOPs can vary. Additionally, it can be harder to generate positive profitability metrics for some sectors than others. Since there are nine parameters, the Piotroski F Score for a company can be between 0 and 9. So naturally, companies at the bottom of the scale (0-3) can be considered companies with weak fundamentals.

Buying the (undervalued) high-FSCORE firms is for most investors easier than shorting the (overvalued) low-FSCORE firms. Circumventing firms with low-FSCORE characteristics may be advisable to investors regardless of the considered weighting scheme and irrespective of the applied control variables given their persistent underperformance. To investigate the association of FSCORE with future firm profitability, we follow the methodology described in Bradshaw et al. (2006) and conduct Fama–MacBeth-type regressions based on annual realizations of fundamentals. Specifically, we estimate a firm-level cross-sectional regression of the firm’s future profitability using return-on-assets (short-term or long-term) on current profitability, firm size, and FSCORE, which all can be observed before the future firm performance is realized. Our investigation is inspired by Piotroski (2000), Piotroski and So (2012), and Walkshäusl (2017), who have stressed a positive univariate relation between FSCORE and future firm profitability.
Momentum (MOM) is the cumulative prior 12-month stock return, skipping the most recent month (Jegadeesh and Titman 1993). Following Fama and French (2015), operating profitability (OP) is revenues minus cost of goods sold and interest expense, all divided by book equity.Footnote 3 Investment (INV) is the annual change in total assets divided by lagged total assets. For the later analysis of the association of FSCORE with future firm profitability, we follow Piotroski (2000) and define profitability based on return-on-assets (ROA), which is net income before extraordinary items divided by lagged total assets. The control for profitability in the q-factor model of Hou et al. (2015) that is applied as a further robustness test is based on return-on-equity (ROE) and defined as net income before extraordinary items divided by lagged book equity. The observation that this has a more significant impact on the long leg of the FSCORE premium than on its short leg is consistent with the concept of arbitrage asymmetry (Stambaugh et al. 2015).
What Is a Piotroski Score
Portfolio sorts represent a very useful approach to investigate how average returns vary with different levels of the variable of interest. However, the portfolio-level analysis also has the potential shortcoming that much of the individual stock information is lost through aggregation. In addition, showing that there exists a positive FSCORE-return relation does not rule out the possibility that the identified return effect is just a manifestation of already known determinants of the cross section. The next section reviews the existing literature in more detail and provides a synthesis of our contribution in comparison with previous works. After that, further robustness tests are provided before the final section concludes the paper.
His strategy is based on a rating system for value stocks called the Piotroski F Score. It is one of the best strategies to invest in value stocks, and due to its simplicity, even retail investors can use it with ease. In the world of finance, geopolitical risk refers to the potential impact of geopolitical events on the economy and financial markets.
Undervalued Companies With High Piotroski F-Scores
In conclusion, the Piotroski F-Score strategy provides a simple and effective method for selecting stocks with good fundamentals. By focusing on companies with strong financials, you can benefit from better returns, reduced risk, and a more diversified portfolio. However, it is important to remember that while the Piotroski F-Score is a useful tool, it is not a guarantee of success.
Piotroski F-Score Strategy Backtest – Does It Work? Performance
Given the discussion above, it should be clear that investors must determine the Piotroski score of companies over multiple years to pick stocks that consistently outperform. It is also a good idea to assess the Piotroski score for companies that trade at a relatively low valuation since they have a higher potential to scale up. Everyone wants to buy low and sell high, but finding the best value stocks combines luck, science, and art. The Piotroski F Score offers a comprehensive approach towards selecting fundamentally strong value stocks, albeit the usefulness of the method is somewhat questionable in today’s market. As for Tesla, it can be hard to make the case that it’s a value stock given its high P/B ratio.
What Is a Piotroski Score? Definition, Meaning, and Example
Stocks with a score of less than three are considered to be weak, and stocks with a score of more than seven are considered to be comparatively strong. In this article, we will learn about what F-score is and how to calculate Piotroski F-score in Excel using the ready-to-use template provided by MarketXLS. These findings are altogether consistent with the view that investors tend to underreact to changes in firm fundamentals (e.g., Lakonishok et al. 1994).
To use the piotroski score, one needs to understand the following criteria and sub-criteria.

The final Piotroski screener variant is the “Piotroski High F-Score – Large Cap”. This screener looks for companies that have a score of 8 or 9 and a market cap greater than 10 billion dollars and trade on the NYSE, NASDAQ or Toronto exchanges. Screening for an increasing gross margin ensures that the company is able to keep its costs under control, whereas screening for increasing asset turnover ensures that the company is able to grow its sales relative to its assets. In this section, we further test the robustness of our key findings using value-weighted returns that overweight larger firms and alternative methods for risk-adjusting returns based on the CAPM and q-factor model. Before we present our empirical analysis, we review the existing research on FSCORE in investment strategies in more detail with the aim to synthesize the contribution of our study in comparison with previous works. For ease of assessment, Table 1 summarizes methodological aspects and performance-related findings of the literature.
The majority of previous works use, like the original study of Piotroski (2000), four-factor model adjustments (4F) with controls for firm size, book-to-market, and momentum in the spirit of Carhart (1997). Given the more recent asset pricing extensions of Fama and French (2015, 2018), there exist so far only three studies that additionally control for operating profitability and investment. These studies focus on the USA (Turtle and Wang 2017) and Europe (Tikkanen and Äijö 2018; Walkshäusl 2019).
Among the countries classified as emerging by MSCI, we select those for which data coverage enables us to calculate valid FSCORES from the start of the sample period, which basically corresponds to the 15 largest markets in this region. We collect monthly total return data on common stocks from Datastream and firm-level accounting information from Worldscope. To ensure that tiny or illiquid stocks do not drive our results, we follow Ang et al. (2009) and exclude very small firms by eliminating the 5% of firms with the https://1investing.in/ lowest market equity in each country. In addition, we exclude firm-year observations with negative book equity and financial firms with Standard Industrial Classification (SIC) codes between 6000 and 6999 (Piotroski 2000; Piotroski and So 2012). Since we focus on examining FSCORE’s post-publication performance, the sample period is from July 2000 to June 2018 (henceforth 2000–2018), and the dataset comprises on average 6787 firms per month from developed countries and 5016 firms per month from emerging countries.
In his seminal work, Piotroski (2000) develops an accounting-based composite measure of the firm’s fundamental strength, the FSCORE, which employs historical financial statement information to identify fundamentally weak and strong firms among value stocks. His results on the US market reveal a significantly positive FSCORE-return relation among firms with high book-to-market ratios that is robust to standard controls of that time. The Piotroski F-Score strategy is a stock selection method that evaluates a company’s financial health to determine whether a stock has strong fundamentals. The strategy was developed by Joseph Piotroski, a finance professor at Stanford University, and is based on the idea that companies with strong financials tend to outperform those with weaker financials.
