Abstract：
The paper examines the relationship between both individual and institutional investor sentiment measures and the risk-neutral skewness of seven stock index options comprised of either growth or value stocks. It provides novel evidence that growth index option prices are affected by sentiment measures. The regression results indicate a significantly positive relationship between sentiment measures and the risk-neutral skewness estimated from four growth index options and a negative relationship with two value index options. The results are economically significant since an associated long-short trading strategy yields high abnormal returns with a Sharpe ratio of up to 1.1 and zero exposure to systematic risk. These high abnormal returns provide evidence of a value premium type anomaly in the index options markets. Keywords: Risk-neutral skewness; Growth options; Option market anomalies
