The more important question is: how would anyone here have the slightest of clues if something was really going on? This leads me to ask: What volume? This leads me to also ask: Does anyone here even pay the slightest attention to the information provided here on Yahoo?
If you had clicked on the chart for AMRI, you would have noticed that early in the Trading Day, there was one trade for 247,000 shares. Subtract that from the total for the day. What volume?
My guess is that the relatively large trade was a large shareholder selling; a bargain hunter buying; or both things happened at the same time.
Interesting. According to Yahoo: four trades have accounted for 208,200 shares so far today. One trade was for 100,000. In retrospect, April 12-13 might have been a good time to buy and then sell if it hits $5
