What you failed to mention is that in the preceding 4 years the stock price was flat despite Tesla growing revenues 50% a year and improving every other business metric.

What really happen was: for several years Tesla was executing very well but faced unprecedented amounts of FUD. That kept (many but not all) investors away.

But you can only fool people for so long.

Investors finally realized that none of the FUD of imminent bankruptcy etc. is happening and things flipped.

That was the reason for the 10x run up of the stock price within 1 year.

Not Tesla is fairly valued based on modest assumption about the future 5 years out and doing DCF (Discounted Cash Flow analysis).
