The number 1 reason why ARNA will not go up in the short term...
Too many retail investors. Wall Street loves to rip off retail. They even pay Adam and others to publish negative opinion on ARNA just to shake out retail. I bet they even pay the gov and ARNA management too.
That has not been working here, retail understands what they have and they are holding through all of the dips and quick sell offs. In fact many are buying these shorted shares with the intention of holding them for much higher prices. Tutes are buying into that selling as well. When we finally get sales and guidance and the company starts to hit those numbers there won't be a lot of shares to buy to cover those short positions.
That is how a short squeeze happens, a stocks value is underestimated and when it becomes obvious the stock is worth so much more the shorts have to bid up that price in order to get shares to cover. If that happens fast enough the B/D will buy in at any price adding fuel to that fire.
