Abstract
Many studies report that the size effect in the cross-section of stock returns disappeared after the early 1980s. This paper shows that its disappearance can be attributed to negative shocks to the profitability of small firms and positive shocks to big firms. After adjusting for the price impact of profitability shocks, we find a robust size effect in the cross-section of expected returns after the early 1980s. Our results highlight the importance of in-sample cash-flow shocks in understanding cross-sectional return predictability.
