I don't see any news but somebody knows something!
I have to believe that it is tied to the fact that CAH lost the Walgreens contract to ABC. CAH and MCK are both down hard, while ABC is nicely up. Maybe some were expecting MCK to get it?
Thanks, I have to think that deal is the reason too. But moreover, WAG will be buying part of ABC, so we know ABC will have the WAG contract locked up virtually forever and MCK won't ever get a piece of it.
