Methodology & criteria
The simplified screener version of Greenblatt's "The Little Book That Beats the Market": above-average companies (return on capital ≥ 25%, approximated as ROE × equity ratio) at below-average prices (positive P/E, at least 5 to filter out data outliers). Financials and utilities are excluded as in the original, minimum market cap $50 million. We back-tested the formula for you from late 1999 to July 2026: the full original ranking of earnings yield and return on capital returned 14.48% a year against 8.28% for the S&P 500 — the screener version this scanner implements came in at 10.07% a year. Honest caveat: since 2010 the formula has trailed the S&P 500 by roughly 3.8 percentage points a year on average. Source: fundamental data.
