Not sure I understand your reasoning. If I (or anyone) is on a buying spree - and there are willing sellers out there - the volume of activity may have nothing to do with news - it may simply be a matter of folks sensing a buying or selling opportunity (ahead of pending news - or a belief of pending news).
I'm not sure how heavy volume relates to new shares being distributed or to existing shares being traded on the open market. Obvioulsy GOOD or BAD news will result in trading spikes, but the absence of any news with high volumes of trading could by any combination...yes?
