'What Happened Today' ...You nailed steady , an organized short attack with timing corresponding to a shorter's tweet today. Investors should be keenly aware of what size the short position is, which way it is trending, and days to cover. KNOW that they will defend it with a small percentage of the stock sold as compared to the total short size sold into the market short.
Shorts at the close have around an avg size % stake for a Bio. Currently at the close 8,707,363 sh X $10.60 sp = $92,298,047 in current short value.
Today was a no news day with a -16.54% drop in share. A good news PR with volume can reverse the effect and the shorts can contribute to up trend by buying shares, along with other retail buyers and managed funds/institutes.
Bottom line that actually rules will be the trial results. It may not be fully valued instantly but will gravitate to it's true basic value based on revenues/profits/profit sharing and expenses.
If you are a new buyer or a present shareholder still buying, then this short attack will allow you to add cheaper shares sold by weak hands,
