Abstract: We investigate the cross‐section asset‐pricing patterns of major cryptocurrencies from 2017 to 2021. We show that the basis, momentum, and basis–momentum factors earn statistically significant excess returns, a result consistent with the findings reported in the commodity futures literature. The basis is the strongest signal predicting cross‐sectional differences in cryptocurrency futures returns; the momentum‐induced risk premium is not statistically powerful, whereas the basis momentum‐induced risk premium disappears when accounting for the basis‐induced risk premium. Daily factor returns are statistically much stronger than weekly factor returns. Monthly factor returns are nonsignificant.
Abstract: We contrast and evaluate two of the most popular responsible investing strategies employed at present: negative screening and engagement. As a backdrop, we consider the challenges faced by the University of Cambridge, which mirror those experienced by institutional investors worldwide. Specifically, we make use of issues raised at the recent “Divest or Engage?” conference at the University. We discuss emerging academic evidence from recent, and hitherto unpublished, papers in order to provide an up-to-date perspective. We describe the challenges in excluding undesirable assets from investment portfolios and present evidence on the effectiveness of engaging with investee companies. The strategies of divestment and engagement are often employed as complements to each other and this can be advantageous. We caution that investors need to be aware of the disquieting evidence that ESG metrics differ considerably across rating services, and the choice of data provider can have a fundamental impact on the ESG credentials of institutional portfolios.
