“…There have been mixed evidence of persistence and attenuation of anomalies since their discovery (e.g., Brennan, Chordia & Subrahmanyam, 1998; Cakici & Tan, 2014; Chung, Hsu, Ke, Liao & Chiang, 2016; Fama & French, 2015; Gillan, 1990; Kothari, Shanken & Sloan, 1995; Loughran, 1997; Schwert, 2003; Shum & Tang, 2005). Reasons being cited for attenuation range from increased implementation of strategies to capitalize on anomalous patterns by practitioners (Schwert, 2003) to deregulation of financial markets and enhancement of trading facilities (Chung et al, 2016). Besides, there have been evidence of reverse anomaly effects (Claessens, Dasgupta & Glen, 1995); time-varying behaviour of anomalies (Wu, Liu & Chen, 2016); anomalies varying according to monetary policies of the government (Jensen, Johnson & Mercer, 1997).…”
