报告内容简介：

Common measures of aggregate stock market volatility are priced differently in the cross section of stock returns. Stocks with high sensitivities to changes in realized and expected volatilities have significantly low average returns, while option implied volatility is not priced.

The differential pricing of market volatility risks is hard to reconcile with existing theories, but potentially consistent with partial segmentation between index options and equity markets. I argue the comovementbetween option implied and actual stock volatilities contains valuable information about time varying segmentation between equity and options markets. The two markets appear to have become more integrated in recent years.
