Market Dynamics and Momentum Profits

Abstract

AbstractRecent evidence indicates that momentum profits are sensitive to market conditions. We find that the profits are higher when the markets continue in the same state than when they transition to a different state. These findings support Daniel, Hirshleifer, and Subrahmanyam (1998), who suggest that investor overconfidence is higher when the markets continue in the same state (UP or DOWN) than when they reverse, predicting higher momentum profits in the former. In contrast, our evidence following DOWN markets is not consistent with the other competing models for the market-state conditional momentum profits.
