Starting a new trial isn't anything to get excited about - finishing the trial and having good results now thats another story. I know I wouldn't hold awaiting that "news" nor would I be a buyer expecting a greater fool theory type pop on it.
Late summer is normally a pretty low news flow time for all bios - not ARIA in particular BUT I did notice the chart pattern start to break down last week and we are seeing follow through. $2.40 should be decent support in the next 2 - 3 weeks.
