Very little stock for sale causing price to fall up
Volume picked up yesterday as a large buyer surfaced and bought as much stock as they could get their hands on withut spiking the price. A hour or two before the close, the buyer went away and let the price drift down just enough to keep the price from running.
As expected, the buyer is back today, but there is no stock available meaning that they will have to raise the price or go away empty handed.
Expect AMPE to rally from here because there is no stock available and everybody knows that big news is coming soon,
