“…Nevertheless, the effect remains statistically significant in all other 8 deciles and in the EW and VW portfolios, even in the last subperiod. Consistent with other studies, we conclude that the results show a decline in the magnitude of the effect over time (e.g., Brusa et al, 2000;Gu, 2004;Kohers et al, 2004;Mehdian and Perry, 2001; Kamara, 1997, for similar evidence), but the effect has not vanished.…”
