DD, if one were a naked short, what would they need right now before NWBO perhaps releases incontrovertible good news with easy to determine PPS increase impact? Answer: Naked shorts would need lots of available shares at low borrowing rates in order to cover (perhaps in dark exchange). And why would brokers, who set those rates, be compelled to make a huge amount of short shares available at low rates so that naked shorts might cover? Perhaps because they would be on the hook if the naked shorts don’t cover.
If true, and if that’s what’s up, it may, as you say, become more clear on Monday.
