Not even a little bit. Musk has a charisma of a bag of potatoes.
What matters is that Tesla had 10 years of 50%+ revenue and unit growth, on average. They performed better than any of the FAANG companies.
With Giga Berlin and Giga Texas ramping up, Cybertruck, refreshing Model 3 for lower cost of production, ramping 4680 battery production, lithium refinery in Texas, Inflation Reduction Act in US => the 50% growth the company is guiding for in the next several years seems to be in the bank.
Charisma is not an absolute and objective measure. Some people will find Trump charismatic to them, some people will see him completely opposite.
I personally find Warren Buffett very charismatic, some people will probably see him as an old and wrinkled guy who is boring them with stories they don't care about.
As investors are generally mostly interested in money, ability to get shit done and generate profits reliably IS charisma.
And in case of Tesla a lot of this expectation was based on charisma of its owner and on belief that he is the force behind Tesla's spectacular success.
Now, if you are an investor, it seems the owner lost its focus and made a bunch of questionable decisions. This puts a huge question mark on whether he will be as involved and as effective with Tesla in the future.
