Studies on ethical funds have usually focused on how to establish criteria for choosing stock in which to invest, which are the most commonly used criteria, ethical funds' relative return, the unique features of their management, etc. In contrast, this paper focuses on deeper dimensions of the...

In this paper we test the profitability of momentum strategies in the United Kingdom, Germany, Japan and China over the period 1991 to 2006 and sub-periods. Both RSS (Relative Strength Strategies) and WRSS (Weighted Relative Strength Strategies) are used to form the momentum portfolios. We find...

This paper uses the cross-sectional variance of the betas to study herd behavior towards the market index in major developed and emerging financial markets (categorized as Developed group, Asian group, and Latin American group). We propose a robust regression technique to calculate the betas of...
