It's not as big or as consistent as you might think, but it's not negligible either. Paul Bischoff and Matthew Dolan have done some research and posted the results here
Interestingly, companies that suffer breaches tend to be underperforming companies anyway. However, their performance improves after the breach, at least compared to market averages. Low point tends to be about 2 weeks post-breach, but for the following 6 months, the companies tend to outperform the market.
Maybe suffering a breach serves as a wake-up call?
It's a relatively small data set, and doesn't relate much to small and non-public businesses, but it's interesting to ponder.
