I'm sure that every squeeze is different, but the MMs are always the same. I really doubt that they are just going to throw open the vault and buy back the 30 million shares that they are short all at once. If I were them I wouldn't do that, anyway. I'm certainly no expert, but there's one thing I know, and it's that the MMs are not going to go down without pulling a few tricks first.
But with that said, I agree that the EVCC chart is only an example of what a squeeze looks like, and there are plenty of other ways things could go down.
GL2us!
