Three possible opinions/answers to your question:
1. Yes, because the market (based on thousands of bidders) says it is.
2. No, because in the short term Tesla will never achieve the financial success that the share price suggests, their current product is still being perfected and electric vehicles aren’t that popular yet.
3. Yes, because in the long term Tesla will survive and thrive at creating value in ways we can’t yet fully appreciate as a result of their corporate commitment to innovation and taking risks.
