After market trading is often limited to very small volumes (especially in cases of smaller companies like PIP/SIGA where volumes are already low). As a result, they may provide an indication but are often unreliable as predictors of where stock will actually open when trading begins during market hours. Moreover, after market trading is not accessible to most investors. What matters then is what happens during market hours. You can say stock traded up or down in after market trading but it wouldn't show up that way on the chart (i.e. those trades are not part of official market records). That is why you see gaps in stock charts. Thus, description would be that stock has either gap up or down on day when trading resumes in the market. This would apply following a trading halt (intraday), or between trading days (whether overnight or over the weekend).
Parker, ah trading indicates the price WAS pushed up. This is all about supply and demand. I''m guessing it will gap up tomorrow, and it will probably be a gap & go type of gap. It is also way out of the Bollinger Bands BB). A stock that is way outside the BB usually indicates strength. One of 2 things will happen.........1) PIP will try to move back inside the BB or ......2) the BB will try to catch up with PIP.
Before I leave you, I want you to be aware of one thing. All gaps are filled 95% of the time. It doesn't matter how long it takes. I have seen this happen many times.
