Question- could my stock be getting driven into dirt by short selling?

Hello! I happen to like a biotech called ICVX. They recently had some good clinical trial results which brought the stock out of the gutter. Something like $3 to $15. Well the stock cooled off and started to consolidate down. I expected as much. But now it just won’t stop falling. Broke $6 today. At first I thought it was simply the sector movement, but today biotechs are up and yet it’s going lower. I found the short sale volume and it looks to me that the stock is being driven down every time it bumps the 10dEMA. Would a more experienced person lend their opinion? Is there a way to know what’s driving a stocks movement? Can it be short sold into the dirt?
