BMAS is one of the market makers and have been buying heavy for quite some time, no selling. None of us really know who they are, but appears they are buying for the benefit of SPNG IMO to promote the huge short squeeze that is setting up as we speak.
Bmas is a MM that is buying for a person or a group of people. Many speculate BMAS is Steve M and he defends his stock by buying up shares. Just my opinion.
