Tesla from Sept. 20, 2019 to Sept. 20, 2020 revenue is $28.17 B. Ford revenue in the same period was $130.9 B and GM was $115.8 B. 28.17 * 1.5^5 = 213.9. That doesn't even include the inevitable decrease in sales for F and GM if Tesla grows that much.

It’s Profit that matters, not Revenue.

Stock price is usually factored as a PE ratio - Price to Earnings.

Price to Sales also exists, but usually only for emerging companies that have just gone public and are growing rapidly.
