Its actually a good thing for longs when you see MM trying to walk this up. There appears to be no foreseeable negative catalyst. A good way for anyone with a lots of shares looking to sell is to walk PPS up as high as they can before the next positive news. We should see this type of trading action until the next news release.
OK - So I am an "unsuspected soul". Watch me smile in the days ahead. I think I know exactly what I have here and with new generics launching and our ART to come - our souls will rejoice! Max
