In our recent working paper on the systemic effects of cyber risks expressed via financial markets, we have shown the first empirical evidence of systemic (cross exchanges and cross companies) contagion from cyber risks to share prices of the world’s largest corporates, starting with 2014. You can read the full paper here: http://trueeconomics.blogspot.com/2017/01/23117-regulating-for-cybercrime-hacking.html.
Some new evidence on the effects of cyber crime on corporate performance is now also presented in a recent FactSet analysis here.
In this article, FactSet look at the corporate performance effects arising from five “notable” 2016 data breaches, specifically focusing on the stock performance. The methodology in this analysis, unfortunately, is weak and does not lend itself to establishing any specific hypotheses, including those claimed.
Still, an interesting collection of factoids and illustrations of the shorter term impacts (or lags in such).
