I'd assume folks betting that there will be some good news in Q or post Q to sell into. low float, easy to move probably to .15 at least. 10x profit for somebody buying one hundred thousand to a few hundred thousand shares down in the .01s. good return if the Q is good and it causes interest.
not me though and my measly post split share total and lack of funds. Oh, if only I had waited a year. :- )
