What Is the Magic Formula and How Does It Work
The Magic Formula is a quantitative stock-screening method that selects companies based on two metrics: earnings yield and return on capital. Earnings yield is calculated as earnings before interest and taxes divided by enterprise value, while return on capital measures operating profitability relative to invested capital. The strategy ranks stocks by each metric, combines the ranks, and buys the top-scoring companies while selling underperformers.
Backtests of the Magic Formula show strong long-term outperformance versus the S&P 500, though results vary by market cycle and implementation. Greenblatt's book "The Little Book That Still Beats the Market" details the formula and provides historical data. The strategy requires periodic rebalancing and discipline to avoid emotional deviations.
