Do buy it when it dips though. Entertainment.I meat Tesla has a $800 billion market cap and is estimated to do $31 billion in sales next year. That's like 26x times sales alone. Facebook who has a market cap of $716 billion and is estimated to do $84 billion in sales next year is like 9x sales.
Tesla has a lot of room to grow but at the same time EVs are under 5% of all cars sold so there's a lot of runway left before they take off and own the market. Whose to say what the market share looks like in 10 years? I also doubt the electrical grid as it is can support everyone driving EVs.
I don't think price to earnings is totally fair to value Tesla at as they barely turn a profit right now. Price to sales works better.
