Piotroski F-Score

Also called: F-Score

The Piotroski F-Score is a nine-point checklist of accounting tests, each scored one point if the company passes and zero if it does not. The total runs from zero to nine and summarises whether a set of reported financial trends improved or deteriorated between periods.

How it is measured

How is Piotroski F-Score measured?

The nine binary tests group into three families: profitability — positive net income, positive operating cash flow, an improving return on assets, and operating cash flow exceeding net income; leverage and liquidity — falling long-term debt, an improving current ratio, and no new share issuance; and operating efficiency — an improving gross margin and an improving asset turnover. Each passed test scores one point.

Why it matters

Why does Piotroski F-Score matter to a swing trader?

The F-Score is worth knowing because it is the clearest illustration of a whole class of scoring approaches: reduce a set of reported figures to pass/fail tests, then count. That design makes it transparent and reproducible from filings alone, and also blunt — it treats a marginal pass and a large one identically, and it moves only when new financials are filed, which for most companies means it is static for weeks at a time.
