Abstract

Using a novel data set of intraday options and underlying stocks prices of the global systemically important banks in Europe, we analyze the role of options market in discovering risk during the subprime crisis. The risk-neutral moments - volatility, skewness and kurtosis - are computed every five minutes from the options market and the realized moments are obtained in same frequency from the underlying. Utilizing information share approach we find some evidence of the increasing role of options market in discovering risk after the crisis. The information share dynamics cannot be explained by the market activity variables such as trading volume and return volatility.
