There are lots of data points that seem to confirm the overseas clinical trials, a near-term launch of the HCV combo trial and the Duke/Gates/HIV alliance. Also hear that the cancer trial is going quite well and a top-line progress report may be available long before year end.
Regarding Influenza, however, there are good reasons to believe we will learn the "go/no-go" decision in late Sept. but it is just hope and speculation on my part that we will get a green light.
I agree with your view that most of the shorting comes from hedging by those who are accumulating. Hopefully a series of back-to-back PRs in Sept will convince those funds to cover and raise the bar on the trading range where the next round of accumulation occurs.
All IMO
