People were asking legitimate questions about orders and finances and he told them to shut up, while directly insulting their intelligence. That was an extremely bad sign to me. When I saw that even after that, there was still support in the $270s, I declared the market too bullish for my liking and was no longer comfortable being short.
As far as I'm concerned TSLA has to turn a profit in the next couple of quarters or they're just not going to be able to be competitive enough with the additional financing they're going to require. Elon promises they won't need to raise capital. If he's right, great. But I'm not betting on it one way or the other.
