Although sustainable investing is becoming a mainstream ambition, investors disagree on how to best measure corporate sustainability performance (CSP). Environmental, Social, and Governance (ESG) ratings are the dominant CSP metric in the market, but they focus on financial materiality rather...

This paper shows that low-risk stocks significantly outperform high-risk stocks in the local China A-share market. The main driver of this low-risk anomaly is volatility, and not beta. A Fama–French style VOL factor is not explained by the Fama–French–Carhart factors, and has the strongest...

This paper gives an unbiased estimator of the variance of overlapping returns. The estimator improves upon that proposed in Lo and MacKinlay (1988) [LM] (which is widely used in practice), as the LM estimator is consistent but not unbiased in small samples. The relevance of unbiasedness for...

We examine the empirical relation between risk and return in emerging equity markets and find that this relation is flat, or even negative. This is inconsistent with theoretical models such as the CAPM, which predict a positive relation, but consistent with the results of studies for developed...

The evidence for the existence of a distinct low-volatility effect is mounting. However, implicit exposures to the Fama-French value factor (HML) seem to explain the performance of straightforward U.S. low-volatility strategies since 1963. In this paper I show that the value effect can neither...

Some exchange-traded funds (ETFs) are specifically designed for harvesting factor premiums, such as the size, value, momentum and low-volatility effects. Other ETFs, however, may implicitly go against these factors. This paper analyzes the factor exposures of US equity ETFs and finds that,...
