bbhuey: Remember that this last week before Labor Day is usually very slow and traders are often away. Since activity is low, there are a lot of opportunities for the stock price of a low volume trader like CTGI to be manipulated. You are seeing some of this right now, INO.
If trading is to fill the gap, the volume will be important. A quick spike down is usually not as significant, but a rash of shares traded at the bottom of the gap would not be good.
