A reason why price likely bounced from near the previous ATH is because that's where the most liquidity for buyers exists now. In order for shorts to close, they want to get the lowest possible price to buy back their shares, even if it's still at a loss. Buying at $80 is way better than buying at $300. If that's the best they can get, more can be squeezed out of them if price bumps back up towards $200 and above. But there may be less fuel for a further short squeeze. All speculation, of course.
