How the Piotroski F-score works
One point for each of nine tests, this fiscal year against the one before: positive return on assets, positive operating cash flow, rising return on assets, cash flow above net income, falling long-term leverage, a rising current ratio, no new shares issued, a rising gross margin and rising asset turnover. The ratios are the ones on this site, so each can be checked.
Joseph Piotroski (2000) called 8–9 high and 0–1 low; reading it in three bands is the common convention:
| 7–9 | Strong — most fundamentals improved |
|---|---|
| 4–6 | Mixed |
| 0–3 | Weak — most fundamentals deteriorated |
Where this differs from the paper: return on assets is on average rather than beginning-of-year assets, and weighted basic shares stand in for shares issued. The score is shown only when all nine tests can be worked out, which takes three fiscal years; banks and insurers, which report no current assets or gross profit, have none.
