I generally agree with you that many if not most computer security problems don't rise to the level of damaging a business enough to effect the stock price. There was a recent hack and short incident in the crypto currency world though where an unknown individual shorted a large amount of ETH right before revealing a major flaw in the design of the DAO that allowed them to steal all the funds. They forked ETH shortly there after to deny the stolen funds to the would be thief but they still made a killing of their short position. On the investigative journalism front the case of Lumber Liquidators and Herbalife come to mind both of which had damaging information exposed by investors shorting the companies' stocks.
