"If that was buying why no increase in sp?" I doubt anyone can say for sure why the share price failed to increase if it was a buying spree. However, I did notice what seemed like a spike in FUD the day before and during the 6M+ volume day. I don't have visibility so I cannot surmise whether stop losses were taken out.
Best guess, someone, some entity forced it down sub .02 to see how much they could buy via stop losses many had forgotten about, etc. just a theory that I’m sure will be dissected, like a frog by a freshman in a biology class that would rather not be there!
