Shorts are probably covering
Over 11 million shares were shorted between March 15th and April 1st. Approximately 22% of the traded shares volume was short. Now short info is about to be updated (April 16th) and for sure many more shares were shorted. The additional shorts don't want to be left with these dangerous short positions, once we know about them. Deepblue, I think, is one of those shorters. https://shortdata.ca/stock/HVT.V/
