Good question, not sure. Either people with buy orders that they forgot about, a select few who really still believe in the company or MM's/promoters who want to give it on more promotion. Who knows, a combination of all 3 is the likely scenario.
What do you think? There is still the chance MM's let it run up a few ticks but that is looking less and less likely as time goes on.
If somebody is still buying it could only mean that the show ain't over yet.. have seen it several times with different stocks, when the curtain looks like falling, it reopens and the show starts all over again.. ! Will see..
