There was an aborted squeeze in January that quite clearly did not reach its potential as it was stopped in its tracks by the brokers who turned off buying.
Since then the stock has continued to be sold short and there are many theories about manipulation (illegal or otherwise) that you can either believe or not.
For me, it’s always come down to reading between the lines. I look at the people who hold the stock (self included) and extrapolate from there. Do I think it’s possible that there are only 76 million shares + Dave’s 12% in circulation? No. Could it be a ludicrous amount more? Well maybe. Could that lead to a massive short squeeze? Yes, it could.
