Even if you don't believe in the science it is not a good move to short so low so close to primary endpoint, and nobody did. Check the published short interest on Nasdaq site, it has not increased in a year.
And on the other side I'm sure plenty of people that don't believe at all in DCVax will buy shares in coming weeks just to benefit from the amazing risk/reward going into binary event.
But with all this good data released I don't see how anyone that did serious DD would not be convinced that this trial will succeed.
