Because you say it’s true?
No, because anybody that actually follows things knows.
Tesla has, to this day, never come close to making a profit. Ever. In fact, it's several billion dollars in the hole.
Elon Musk has promised projection after projection after projection and has never to this day met a single one of them. As of right now, they lose about 8,000 dollars on every car they sell.
It gets worse.
Musk is now under investigation by the SEC. Chances are, he's going to be fined clear to Mars and may well be kicked out of his own company in much the same way Martha Stewart was. The guy has gone completely off the deep end, spouted things out of his mouth that aren't only untrue, but are in fact illegal.
Tesla was a good idea. In the hands of someone stable, it MIGHT have worked. But all it has become is a stunt program to sucker people out of money. It has, to this day, never met one single projection, one single quota, or one single promise.
That's why it's lost about 5 billion dollars in value in just the last couple of days.
It's only going to get worse.
