摘要：

We document a strong, positive relation between stock market anomaly returns and trading activity in options, inconsistent with the idea that options trading improves the informational efficiency of the stock market. Moreover, the positive relation between option volume on anomaly returns concentrates in stocks with high short-selling constraints. Additional analyses suggest that the negative joint effect of option volume and overpriced stocks on future stock returns is driven by high investor disagreement associated with heavy option trading rather than intensive informed trading in options.
