We extend the well established link between structural change and estimated persistence from GARCH to stochastic volatility (SV) models. Whenever structural changes in some model parameters increase the empirical auto correlations of the squares of the underlying time series, the persistence in...

This paper shows that low-risk stocks significantly outperform high-risk stocks in the local China A shares 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...
