Tesla is now more valuable that the world's top seven car makers combined at $615bn and is the biggest entrant to the S&P 500 EVER - but experts warn the stock is too high and could plummet at any moment
- Tesla joined the S&P 500 on Monday at $665 a share, making it the most valuable new entrant to the stock index ever
- The company is currently worth some $615bn - more than Ford, Honda, BMW, GM, Daimler, Volkswagen and Toyota combined
- But analysts say the stock is in bubble territory and likely to burst at any minute
- Part of the reason is Apple's announcement earlier this week that it is producing its own self-driving car
- It is also likely to fall with the rest of the market amid fears over a new variant of COVID-19
- Analysts are calling the stock 'dramatically overvalued'
