If I may, I'd like to make an unprecedented move: by contributing to this board with some real input (lol). If you are expecting news after the bell on Friday, it would not be good. Thus, the bid/ask would not be moving up. The relationship would almost always be an inverse one.
If there was significant after hours volume at higher prices with no news, however, you would most likely see an announcement before the bell on Monday. Of course, if that happened, something leaked early.
Hope that helps.
