Piotroski F-score
A nine-test checklist of year-over-year fundamental improvements (profitability, leverage/liquidity, efficiency), scored 0-9.
Formula
Sum of nine binary tests: ROA positive and improving, CFO positive and above net income, leverage down, liquidity up, no dilution, margin and turnover improving
Served as: annual · derived. Annual and quarterly observations are never mixed unlabeled.
Where the inputs come from
- Computed server-side from consecutive annual filings
Listed highest priority first. Every served figure carries its filing, fiscal period and accession; open any value on the financials page to see them.
How to compare it honestly
Compare the score's components across time rather than the total across industries.
When it is not served
Requires two consecutive annual filings; not served for first-year filers.
Missing data is missing evidence: it is never shown as zero and never treated as a conclusion.
What it cannot tell you
Binary tests lose magnitude - a barely-passed test counts the same as a strongly-passed one.
Questions worth asking next
- Which specific tests passed or failed this year?
- Are the failed tests trending toward passing in the underlying series?
Research prompts, not recommendations.
