🎯Piotroski F-Score: The 9-Point Quality Score of a Company

2026-05-10 · 236 views

What is the Piotroski F-Score

The Piotroski F-Score is a nine-point score created by accounting professor Joseph Piotroski. It serves to assess the financial performance and stability of companies, particularly those with low market valuation. The F-score utilizes three main areas: profitability, leverage, and operating efficiency. Each of these indicators measures specific attributes of a company that may indicate its overall health.

1. Profitability

This part of the F-Score includes three key indicators:

  • Earnings Per Share (EPS): If the earnings per share increased compared to the previous year, it scores 1 point.
  • Quality of Earnings: If the earnings are positive, but cash flow from operations is also positive, it gives 1 point.
  • Return on Assets (ROA): If ROA is positive in the current year, an additional 1 point is awarded.
For example, if AAPL (Apple Inc.) has higher EPS than the previous year and positive cash flow, its F-Score will increase, indicating it is healthier.

2. Leverage

Leverage is assessed using two indicators:

  • Decrease in the debt-to-assets ratio: If the debt/assets ratio decreased compared to the previous year, it scores 1 point.
  • Reduction in total debt: If total debt decreased, it also scores 1 point.
For instance, if MSFT (Microsoft Corp.) reduced its debt-to-assets ratio while also decreasing total debt, its F-Score will strengthen.

3. Operating Efficiency

Operating efficiency is measured by four indicators:

  • Increase in gross margin: If a company's gross margin increased, it scores 1 point.
  • Increase in Return on Assets (ROA): If ROA rose, it also gives 1 point.
  • Decrease in days sales outstanding (DSO): If the average DSO decreases, it scores 1 point.
  • Decrease in inventory turnover days: If inventory turnover days decrease, it also scores 1 point.
For example, if ČEZ increases its gross margin and reduces its DSO, its F-Score will also rise.

Significance and Efficiency of F-Score

Backtests of the Piotroski F-Score have shown that stocks of companies with higher F-Scores tend to outperform those with lower F-Scores. For instance, research indicates that a portfolio of stocks with an F-Score above 7 can yield returns as high as 23% better than the market average.

Case Study: Ford Motor Company (F)

Recent examination of Ford's F-Score revealed that its score improved due to increased revenues, reduced debt load, and enhanced gross margin following restructuring. Such evaluations can indicate to investors improving trends within the company.
