@successfulLion4498, Aug/13/2021 was reported a significant increase of short interest, almost twice in the comparison with the month before. Sooner or later there had to be a big drop after bad news. First, due to uncertainty for vaccines future demand (two CEOs predict the end of the pandemic next year). Second, after news, that Pfizer, Merck launch new trials of oral COVID-19 drugs. So, when the short interest increases significantly, we should carefully follow healthcare-pharmaceuticals news. After big drop, the last day, the price recovered significantly and formed bullish hammer candle at one year chart. And the price is on the strong support line again. This stock is ultra volatile, so we must always expect a big fall and a big rise.
