First time ever I have seen 5,000 shares available for shorting at Interactive Brokers during trading hours. To me, this is an indication that insiders have been selling into the volume and volatility created by the pot stock frenzy. For me, as a short, this is good news, as the more shares the insiders sell, the faster the pps will return to a reasonable level based on a sensible valuation of the company. Other possible but IMO less likely reasons for increased availability of borrows are intentional manipulation of borrows (make some available and them pull to force buying to cover) or else some shorts are spooked by the dividend due to uncertainty about the effect on margin.
