In the end, it's just a number, but it's a big one: $ 1 trillion.
The company Tesla is now worth that much on the stock exchange - and yet not even half as much as the iPhone seller Apple and still significantly less than the virtual marketplace Amazon.
The crucial question for all investors is: Are these companies really worth what the stock market promises?
There can be no satisfactory answer to this, who should be able to predict that in the end? Investors have to get used to the fact that previous parameters for intrinsic value such as own real estate, large vehicle fleets or gigantic factory machines that produce haptic products are no longer the measure of all things. Tesla at least sells real cars, but Amazon primarily provides a platform as a business model and is still worth more than 1.6 trillion dollars.
The future is traded on the stock exchange.
It is the overwhelming ideas of even erratically acting CEOs like Elon Musk or Jeff Bezos that inspire investor fantasies.
Tesla no longer sees itself as a car provider, but as a mobility provider.
Maybe today's cars are tomorrow's flying taxis - maybe not.
One of the risks in the stock market is exaggeration.
Not to be infected and to find the right level of risk for yourself, despite all the trillions, remains the top investor duty.
