It makes me think of what was happening with gamestop and amc and various others around the turn of the year. Hedge fund guys were naked shorting (creating shares out of thin air) to drive companies into bankruptcy, but thus had assumed infinite risk. Reddit and twitter beat them at their game by mobbing together to buy shares on select meme stocks.
On the books, it doesn't appear ENZC is heavily shorted, so if the MMs are using naked shorts, they would be periodically short selling to ladder down the price, covering the same day, avoiding any share deficit and stopping would-be retail mobs cold.
But there are other reasons (economy, company performance, tax season) why this selloff could actually be organic, as well as the possibility of parties we don't know about yet dumping shares. Hard to say since a wide swath of the OTC is unusually red right now.
