We examine the impact of single-name option trading on stock price informativeness. By documenting a robust relation and establishing causality, we confirm that option trading causes the stock price to incorporate more firm-specific information. Our findings are through the channels of investors’ acquiring more information and through managers’ voluntary release. The findings are driven by firms with higher information asymmetry and firms with more efficiently priced options.
