Apple and Microsoft seem to be doing okay after many decades. Edison is 200 years old and is on the stock market. It is about finding the right product that will last. Tesla could be one of them if it can survive the next decade.
AAPL and MSFT have a P/E an order of magnitude lower than TSLA whilst both having revenue growth % yoy in the teens. They both make over a $100b in PROFIT a year. TSLA's? $4b and shrinking btw. Their highest P/E's since 2005 was under 50. AAPL reached 100 in June 2003 (around the time of the iTunes Store release.. mid iPod era but pre iPhone).
Comparing with MSFT and AAPL makes TSLA look even more insane.
F sells an order of magnitude more cars (~$190 billion in revenue), and has a market cap of $62.8 billion vs TSLA market cap of $1.59 trillion.
TSLA is ridiculous. Any sane investor would look at those numbers and run as far and as fast as they can.
