What it means

Cheap stocks typically split into two populations: cheap-because-broken and cheap-because-temporarily-hated. Piotroski's F-Score (9 accounting checks) separates them. This pattern fires on the top F-Score quintile within the cheap cohort, with price action not in freefall.

Why it works

Piotroski 2000 showed the top F-Score cheap cohort outperforms the bottom cohort by 7-10% per year. The effect comes from correcting analyst over-reaction to short-term bad news on businesses that are actually improving.

Watch out

Small-cap bias in the original study. Works best on stocks under $10B market cap where analyst coverage is thin. Mega-caps with the same factor profile generally have already been arbitraged.
