The Magic Formula : Value, Profitability, and the Cross Section of Global Stock Returns

Buying profitable, undervalued stocks and shorting unprofitable, overvalued stocks yields significant return differentials in North America, Europe, Japan, and Asia.

Results from double sorts and Fama-MacBeth regressions show that MF explains the cross-section of returns in addition to size, book-to-market and momentum
