I've been watching this stock for some time now (years)... hasn't been very interesting lately, and has shown signs of going into a downtrend. It's up 10% so far today...hasn't been down yet. I really don't understand this. Is it interest rates? They don't have any new meds out, the peak of flu season was two weeks ago, and, as far as I know, AIDS didn't take over the planet last night. What the hell happened?
