You know how many times I've seen dead POS's that suddenly began seeing massive volume because "someone knows something" or "something big must be coming?"
And then NOTHING happened?
A lot.
I'll reiterate what I've said ad nauseam before on this site:
Volume is NOT always an indicator of anything, and volume does NOT always precede price.
I've seen 100 million+ share days where the price never budged.
And 200 shares sometimes moves a stock more than a million does.
Inexplicable high volume could be from a MM or P&D group who's been monitoring the boards and sees people getting excited about a stock, so they take a large position of .0001s and wait for the fish to start biting.
