“…In terms of its explanatory power, the four-factor model performs better than the Fama and French (1993) three-factor model in developed markets; however, in terms of the GRS F-test the results are not consistent in rendering regressions where the true intercepts are jointly zero (Bello, 2008;Brighi et al, 2010;Fama and French, 2012;Humphrey and O'Brien, 2010). Conversely when the GRS F-test is applied to emerging and developing markets the four-factor model is found to be more successful (Nartea et al, 2009;Lam et al, 2009;Lai and Lau, 2010;Cakici et al, 2013;Unlu, 2013;Hasnaoui and Ibrahim, 2013;Vo, 2015;Balakrishnan, 2015).…”
