I've seen NO substantive news either. This seems to be a pattern the past few days. The traders take it down, say, .75-1.00 and then it bounces back up a little at end of day. All I can deduce is that it is the shorts playing around and seeing how low they can take it.
But I think everyone is just waiting for FDA.
OR, if you are a conspiracy type, then someone knows something that WE don't know (and it ain't good news) if you get my drift.
Just guessing.
