of course it can get worse, it can go sub-penny, trading halted, delisted....take your pick.

my guess is that at a minimum, we'll get a PR after Rivera returns from DR spouting all types of possibilities. it should be worth at least a bounce in share price and might be the chance to get out of this stock.
