Reuters headline: At least six US merchants suffering Target-style attacks:
Article mentions Nieman Marcus, TGT but none other.
IF JCP has been attacked will stock take a hit?
In general, not much of a hit. Most large chains have been hit one or more times. But the devil is always in the details - depends on whether and how much financial damage was done to the chain.
I suspect that if JCP came out on MOnday and said 40 million user's credit card info was taken, that JCP would drop 0.50+.
It would add another layer of uncertainty.
How much lawsuits would affect the company as well as costs to improve security.
