It's seems generally irrational, but many stocks are down today that have nothing to do with China and probably won't be significantly affected by the contagion. Se la vie.
Today is a derisking. The question is what is guidance for ani excluding Cort. Other than saying he's filing snda next month on schedule, he can't telegraph any new info on it. FDA will hopefully accept quicky.
Also keep in mind index funds own a nice amount of this stock. There position is not fundamentally driven. So it’s had to make much of recent stock activity. That being said are any generics companies reporting before ANI?
