I'm going to have to partially disagree with this. I agree there is definitely information asymmetry going on. However, usually a movement in a stocks price is lead by institutional money. This is for the most part what every hedge fund competes on, a competitive advantage. If you think that your observation has escaped institutional investors eyes then I'd disagree with you. I'm completely biased as I'm in the industry but I think most people would be very surprised by just how much the average hedge funder knows about the companies they have positions in. There were rumors circulating a couple days before the announcement that this was coming.
