Empirically, we show that (i) small-stock components of traditional value and momentum factors … capture patterns in returns on regional and global portfolios of stocks; (ii) size-effect models substantially outperform … benchmark models in finance; (iii) global small-stock value and momentum components are priced but regional models lead to more …

We report strong evidence that changes of momentum, i.e. "acceleration", defined as the first difference of successive … returns, provide better performance and higher explanatory power than momentum. The corresponding Γ-factor explains the … momentum-sorted portfolios entirely but not the reverse. Thus, momentum can be considered an imperfect proxy for acceleration …

conservatively. Surprisingly, survivor stocks tend to be loser stocks with negative exposure to the momentum factor. Further analyses …

In this paper we address three main objections of behavioral finance to the theory of rational finance, considered as … “anomalies” the theory of rational finance cannot explain: (i) Predictability of asset returns; (ii) The Equity Premium; (iii … are the only possible explanations of the “anomalies”, but offer statistical models within the rational theory of finance …
