The 5 year high was over $30. And a $20 AMC price isn't insane or unreasonable long term expectation (assuming they can make it through the pandemic---which it appears they will).
Game Stops 5 year high was $50. It's currently 300+. Under no circumstance is that an accurate valuation of the company and its earning potential.
But what do I know. I'd say its 50/50.
