Abstract

This paper studies the impact of volatility risk premium of SSE 50 ETF options on the price volatility of the underlying securities. After dividing options into different attributes including different types, market conditions and moneyness, we find that options contain implicit volatility information for the underlying securities and volatility risk premium has a significantly positive impact on the realized volatility. We further discuss the effect of options with different attributes on good and bad volatilities. The empirical results show that volatility risk premium has significant influence on both of them. In particular, the impact of volatility risk premium on good volatility is significantly stronger than that of bad volatility. In addition, we investigate the out-of-sample forecast performance of the volatility risk premium on realized volatility. The results show that the implied information content of deep out-of-the-money options has the highest prediction accuracy for weekly good realized volatility.
