First, The issue with Elon is too aggressive and over stressing team, over committing. Considering Elon’s market & Pressure, competitors like GM rolled his cars.
Elon has received (invested amount) lot of money during bullish period and made all the infrastructure to roll out higher capacity. All he needs to do is streamline his process and roll out the cars properly (Management issue).
In addition, TESLA itself built on low cost (Fremont factory 1.5 B worth he bought it at low costs). Those are hidden book values.
TSLA is charging high price, while cost is low. Elon continues to make R&D and rolling out new models, new limits on charging.
Even today, he is the leader in EV technology. In next 10 years, entire Car industry will change to EV from Gas (some people dispute), but this is true.
TSLA is best to buy as stocks, not options, to hold for next decade, wait for opportunity.
