Developed by accounting professor Joseph Piotroski in 2000, the F-Score aims to separate winners from losers in the stock market.

What Is the Piotroski F-Score?
The Piotroski F-Score evaluates a company’s financial health by scoring it on nine criteria. These are grouped into three areas:
- Profitability:
- Return on Assets (ROA): Is the company generating a profit relative to its assets?
- Cash Flow Return on Assets (CFROA): Is cash flow supporting profitability?
- Change in ROA: Is profitability improving over time?
- Accruals: Are earnings supported by cash flow?
- Funding:
- Change in Leverage: Is the company reducing its debt burden?
- Change in Working Capital: Is liquidity improving?
- Change in Shares Outstanding: Has the company avoided diluting shareholders?
- Efficiency:
- Gross Margin: Is the company earning more from its sales?
- Asset Turnover: Is it using assets more effectively to generate revenue?
Each criterion is scored as 1 (positive) or 0 (negative), for a maximum score of 9. Companies scoring 8 or 9 are financially robust, while those scoring 0 or 1 should be avoided.
Why the Piotroski F-Score Works
The F-Score’s effectiveness lies in its simplicity. It focuses on fundamental momentum—whether a company’s financial health is improving or deteriorating. Here’s why it’s powerful:
- Proven Performance:
- In Piotroski’s original 20-year study, investing in companies with high F-Scores (8–9) yielded an average yearly outperformance of 13.4% over the market.
- A strategy combining high F-Score stocks and shorting low F-Score stocks delivered an astounding 23% annualized return.
- Avoiding Pitfalls:
- Low F-Score companies (0–1) significantly underperform, losing 9–13% annually. Avoiding these stocks alone can protect your portfolio.
- Global Applicability:
- The F-Score has been tested and proven effective worldwide, including in challenging markets like Europe during periods of economic downturn.
At Quant Investing, we believe in providing tools and insights backed by research. The F-Score’s success reflects our ethos: to help investors move past the noise and focus on what works.

How to Calculate the F-Score
Calculating the F-Score manually requires access to a company’s financial statements. Here’s how to do it:
- Gather data on the nine criteria.
- Assign 1 point for each positive outcome (e.g., ROA > 0, debt reduced year-over-year).
- Sum the points to get the F-Score.
Example:
- A company improves its ROA, generates positive cash flow, reduces debt, and increases its gross margin. It scores 1 for each of these metrics, leading to an F-Score of 4.
For a quicker approach, you can use tools like the Quant Investing Screener. It automates calculations and screens for companies with your desired F-Score range.
Practical Applications of the F-Score
- Combining the F-Score with Other Metrics:
- While the F-Score measures financial health, it doesn’t look at valuation. This means you need to use it with ratios like EBIT to Enterprise Value or free cash flow yield to find undervalued stocks.
- Screening for Opportunities:
- Example: Use the F-Score to identify small-cap stocks with strong fundamentals. Small companies often exhibit higher returns when their financial health improves.
- Boosting Strategy Performance:
- Backtests show that combining the F-Score with other strategies, like momentum or dividend yield, enhances returns by over 200% in some cases.
Case Studies: Success with the Piotroski F-Score
Historical Example:
In Piotroski’s original study, high F-Score companies delivered consistent outperformance, even during economic downturns.
In European markets, investors who combined the F-Score with a low price-to-book ratio saw gains of up to 301% over 12 years.

Frequently Asked Questions and Answers About The Piotroski F-Score
1. What is the Piotroski F-Score, and why should I care?
The F-Score is a simple way to check if a company is financially strong. It scores a company on nine areas of financial health, like profits, debt, and efficiency. High scores (8–9) mean a company is strong, while low scores (0–1) are red flags. If you're trying to avoid risky companies, this tool is for you.
2. How do I calculate the F-Score myself?
It’s easy but takes time. Look at the company’s financial reports and check for things like profitability and debt changes. For each positive sign, score 1 point. Add them up—out of 9 total. To save time, use tools like the Quant Investing Screener to automate this process.
3. How can the F-Score improve my investing results?
Studies show that high F-Score companies tend to outperform the market. For example, a 20-year study found that these companies beat the market by 13% annually. Avoiding low-scoring companies also helps protect your portfolio from big losses.
4. Should I only use the F-Score to pick stocks?
No. The F-Score is powerful, but it works best with other tools. Combine it with valuation measures, like Earnings Yield, price-to-book ratio, and other strategies like momentum. Think of it as a piece of the puzzle, not the whole picture.
5. Can the F-Score work on all types of companies?
Not always. It’s most effective for stable, value-focused investments, like mature companies. If you’re looking at high-growth tech stocks, the F-Score may not give the full picture. Tailor your approach based on the company type.
6. What mistakes should I avoid when using the F-Score?
Don’t rely on it alone. The F-Score doesn’t consider a company’s valuation or growth potential. Also, avoid emotional investing. Stick to your plan, even if the market is volatile.
7. How can I quickly find high F-Score stocks?
Use a stock screener, like the Quant Investing Screener. Set filters for an F-Score of 8 or higher. You can also add other criteria, like market cap or valuation ratios, to fine-tune your results.
