This paper examines whether the momentum gap in Huang (2022), defined as the cumulative return difference between past winners and losers in formation period, predicts momentum returns in the Korean stock market. The momentum gap negatively predicts future momentum returns in Korea, even after controlling for established predictors. The predictive power is particularly pronounced for extreme negative returns, commonly referred to as momentum crashes. Although the predictability appears over short horizons, the adverse effect does not dissipate with portfolio rebalancing, suggesting that the momentum gap reflects unfavorable conditions regarding momentum strategy beyond transitory stock‐level mispricing.
