Not sure, I guess shares are changing hands. I don't like the spread, its usually about 4-5 cents, and since I'm in Canada when I buy it I'm only allowed to buy it in $BILZ and not in $BILZF, very frustrating for Canadians I think. Also, my shares show up under the symbol $BILZF but it gets traded under $BILZ, so its some weird stuff, not to mention the halt on the Canadian side last time it popped. Just watching it for now.
