... given the "no substantial news" character of the NDA acceptance, I can only explain today's move with a probably still high short interest of over 20 pct (8.5mn/39mn)*, probably even higher if calculated on the float or non-institutional investors share.
The actual news should come this evening with AACR abstracts**, but judging from the titles they are what one would expected (i.e. IMHO nothing that would justify a 50pct share price jump).
So I realized losses on half of my position based on the "sell on good news that are no news" principle.
