Operating efficiency

- What it detects
- Whether it earns more on each sale (prices or costs).
9.Does it sell more per dollar of assets?

Methodology and caveats
- Bloomberg data as delivered. “—” means no data and counts as 0 in the score.
- Bloomberg's “Quality of earnings” signal is passed by only 27 companies, all loss-making; that is why no profitable company scores above 8.
- Piotroski designed the model for the cheapest 20% of the market (mostly microcaps); among large companies it discriminates less.
- It is a snapshot: subsequent returns have not been measured.
- This is not investment advice.
