To tell over 1500 attendees at a biotech conference is great news this will spread like wildfire, if they tell 10 people each it will be 150k people. If GC gave data today it would have not had the same pop, most people are vacationing now.
I think it is very smart, after the tax loss selling and the flippers to bash it.
Do you really think he AMBS will give bad data in front of all these people? I don't think so!!!

Also the Jan 12th JP Morgan conference will open eyes.
