This goes back to my post a couple days back when I mentioned that RNAZ consistently appears on the Failure to Deliver report due to these Market Makers and/or Brokerages that continue to allow the shares to be sold short with no backing behind them attempting to drive the PPS down. A ton of synthetic/dark pool shares being sold short. Mother of all short squeezes can easily happen if ever word leaked out from the patients that are undergoing treatments for their cancers and seeing great results. Just my opinion and people always should do their own DD!!!
