Data breaches negatively affect a company’s ability to do business, public perception of the company and, new research shows, its stock prices. According to a recent study by Comparitech, such cyberattacks can drive a stock’s performance down on the day of the announcement, and they can slow future growth of a stock for years. Also the sensitivity of the data leaked—credit card numbers versus email addresses, for instance—directly affects Wall Street’s reaction.
