The stock is detached from reality.
It's my understanding that this was another offering, so, essentially, Tesla sold 5% to Tencent at an average price of $217 and change. Current shareholders get diluted. Prices go up.
I don't get it, but I'd love an explanation. Were people, prior to these capital raises, concerned Tesla couldn't raise any more money? That would make sense, but certainly isn't the sentiment I gathered from my travels.
