there's movement at the gdy station

Ok, so we are up 12% at the moment. Last week we were down below 90 cents, despite the fact that there was a free rights issue on offer. Now it has expired, there is no new news and we are up 12%! What gives? I am not complaining as this makes up the largest chunk of my portfolio but it would be nice to know what is going on. I shudder to think it might be leaked news about the closed loop flow test analysis as I thought GDY was better than that. But who knows. Maybe its Wall St, but ATM I am blissfully ignorant of what's going on over there...
