Abstract:
We suggest a flexible method to study the dynamic effect of common risk factors on the profitability of price momentum returns. Unlike the existing work which evaluate momentum profits under constant coefficient time-series framework, our approach helps us to incorporate serial correlations and heteroskedasticity in changes in expected momentum profit level. As a result, the expected momentum profit level differs in magnitude from its traditional counterpart. Our empirical implementation demonstrates new evidence on the predictability characteristics and profitability of price momentum portfolios using our theoretical framework.
