A reexamination of factor momentum: How strong is it?
Recent studies show that most financial market anomalies exhibit a momentum effect. Based on two datasets, (i) an original 22-factor sample and (ii) a more comprehensive 187-factor sample, we find that factor momentum effect is weak at the individual factor level. In both samples, only about 22%– 27% of the factors exhibit strong return continuation and dominate the factor momentum portfolio while the remaining factors do not. The factor momentum strategies do not outperform the corresponding long-only strategies in either sample. The choice of factors affects the ability of factor momentum to explain individual stock momentum.
