We then examine whether cybersecurity risk is priced in the cross-section of stock returns. Portfolios of firms with high exposure to cybersecurity risk outperform other firms, on average, by up to 8.3% per year. Yet, high-exposure firms perform poorly in periods of high cybersecurity risk. Reassuringly, the measure is higher in information-technology industries, correlates with characteristics linked to firms hit by cyberattacks, and predicts future cyberattacks. | URI: | https://hdl.handle.net/20.500.14279/30934 | ISSN: | 08939454 | DOI: | 10.1093/rfs/hhac024 | Rights: | © The Author(s) Attribution-NonCommercial-NoDerivatives 4.0 International |
