The New Magic Formula For Investing
Greenblatt's 'magic formula'—combining Return on Capital and Earnings Yield—consistently outperformed the S&P 500 from 2017 to early 2026. Testing the formula on S&P 500 constituents, portfolios of 20–30 top-ranked stocks delivered 4–6% higher annual returns and superior Sharpe ratios versus the index. Quality (ROCE) alone outperformed value (Earnings Yield) alone, but their combination yielded the best risk-adjusted results.
