| Abriss: | This study examines the impact of cyber incidents on shareholder value. Using data from 2012–2022, we measure abnormal stock returns around reported incidents, adjusting for event-induced variance and cross-correlation. Unlike prior research, we find no statistically significant market-wide abnormal returns once these adjustments are applied. However, data breaches stand out as particularly damaging, with average losses of–1.3% (USD–1.9 billion). The health sector is especially vulnerable, with average losses of–5.2%. Our results suggest that cyber risk is priced selectively by markets, with implications for portfolio risk assessment, sector allocation, and investment strategies. |
