@scottjshapiro My understanding is that a lot of Tesla's valuation is a result of Elon's ability to hype it and himself — compared to other stocks it's overvalued. If the valuation rests on the notion that Elon is a genius, he's doing a good job to dispel the notion during his tenure so far helming Twitter. So basically it's a correction. The bursting of a bubble. Hope you didn't buy at 400.
