I'm going to speculate here: the SP took off in late June on basically no news. There was an announcement regarding the publishing of data in AlZ but that news was essentially already known wasn't it? Either way, this wouldn't normally double the SP of a company. The trial is quite large with 167 people in it and therefore extremely difficult to keep a lid on positive results as they come through. Feels like the news is gonna be good, whether or not it's already priced in over the short-term and this is a buy the rumour, sell the news event - remains to be seen. I say again, all speculation on my part! Fingers crossed
