Tesla is very different from other car companies.
- Tesla owns a large global infrastructure for charging that they produce themselves. And produce a lot of home and destination charges as well.
- Tesla has a very large expanding internal battery production and will be one of the bigger battery manufacturers in the world themselves.
- Other car companies down own their distribution channels and thus make lower margin per car
- Tesla is market leading in grid storage a gigantic market that is about to grow for the next 20 years straight
- Tesla is leading in home solar/storage market that will also be growing for then ext 20 years
- Tesla has the potential leading in self-driving (yes make your jokes now HN)
- Legacy car makers actually make a huge amount of their money from out of warranty part sales, a channel that Tesla has yet to take advantage of because most of the time they have far more new cars and service is still losing money for them. Steady state the huge service network they are building will be very profitable.
Tesla has the clear potential to continue growing 50%+ with improving margin (localization of production, vertical integration) just with production capacity that's already in production. While the other car makers are at series risk of having a huge amount of legacy infrastructure that is losing value while their still large ICE production could very well turn negative margin as volume decrease economics of scale.
You can still call it to high, but saying its made up nonsense is equally incorrect.
Go look at the Wallstreet models, the stock price is defensible even with not all that aggressive assumptions for the next 10 years. Far less aggressive then Tesla internal targets.
It all depends if you believe Tesla can continue to execute. And what position they will be in by 2030 and then what you believe the next 10 years will look like.
