🎓 Are You Using the Piotroski F-Score to Spot Strong Stocks?

How this 9-point scoring system helps identify financially strong companies and avoid weak investments

May 26, 2025

When looking for good investments, it's important to know if a company is financially healthy. In 2000, accounting professor Joseph Piotroski created the Piotroski F-Score, a system that helps investors separate strong companies from weak ones.

This score looks at nine financial factors and gives each company a score between 0 and 9. A higher score means a company is in better shape, while a lower score could be a warning sign.

How the Piotroski F-Score works

The F-Score is based on nine simple financial checks, grouped into three categories: profitability, debt and liquidity, and efficiency.

1️⃣ Profitability (3 points)
✔️ Positive Return on Assets (1 point) – The company is making a profit.
✔️ Positive Operating Cash Flow (1 point) – The business is generating real cash from its operations.
✔️ Higher ROA than last year (1 point) – The company’s profits are improving.

These checks show if a company is making money and improving its financial results.

2️⃣ Debt & Liquidity (3 points)
✔️ Operating Cash Flow is higher than net income (1 point) – The company’s cash flow is strong and not just based on accounting numbers.
✔️ Less long-term debt than last year (1 point) – The company is reducing its debt.
✔️ A higher current ratio than last year (1 point) – The company is in a better position to pay short-term bills.

These points help measure if a company is managing its debt well and staying financially stable.

3️⃣ Efficiency & Stability (3 points)
✔️ No new shares issued (1 point) – The company is not diluting existing shareholders.
✔️ Higher gross margin than last year (1 point) – The company is making more money on its sales.
✔️ Higher asset turnover than last year (1 point) – The company is using its assets more efficiently.

A company that scores well here is managing its costs and assets wisely, which is a good sign for long-term success.

What the score means

After checking all nine factors, companies get a total score between 0 and 9:

🚨 0 - 3 (Weak): The company may be struggling financially and could be risky.
⚖️ 4 - 6 (Stable): The company has both strong and weak points but is in decent shape.
✅ 7 - 9 (Strong): The company is financially solid and well-managed.
