Abstract: We document strong global commonality in country idiosyncratic return variances across 23 developed markets, which is stronger than international return commonality. The global common factor of idiosyncratic return variances is highly correlated with that of idiosyncratic cash flow variances, and is also significantly related to variables capturing aggregate discount rate variation and the conditional market variance. Furthermore, aggregate idiosyncratic return and cash flow variances are predominantly but not always countercyclical.
