Report: Cybersecurity Ratings and Stock Performance

New Research from Journal of Cyber Policy

Abstract: A cyberattack is likely to cause a public company’s share price to drop, at least temporarily. Now, with SecurityScorecard, it is possible to determine the quality of a company’s cyber defenses based on a variety of parameters. We sought to determine if there is a connection between the security ratings of public companies, as determined by SecurityScorecard, and their stock performance over time. This report explores whether there is such a connection, analyzing the relationship between stock prices and security ratings for the companies constituting the S&P 500 index.
