Dendreon's stock got halted at the close out of nowhere and they announced that they would discuss the phase 3 results for provenge over a conference call the next day. More details were discussed at the AUA annual meeting two weeks later to quite all the skeptics. You never know when the news is going to come out. I tried to time DNDN and missed out thinking they would present at the conference but then the stock got halted and I hadn't invested yet. So you never know.
