Is anybody besides the market makers doing any shorting? So far as I can see, that isn't possible. If you tell your broker you want to short NNVC stock he'll tell you it can't be done because no shares are available to borrow. That's actually the usual case for OTC stocks. I checked the stock borrow/loan panel of my broker's app. I can short all sorts of exchange listed stocks, but not NNVC.
