Official price point of invalidation is 437 (0.618 of the most recent move down)
My guess is we're seeing a mini blow-off in after hours that may continue into pre-market tomorrow.
Short interest is building fast to the bear's side.
Short will remain in place, waiting for RSI to dump below 50 for confirmation, but given the amount of volume we're seeing with lack of price action, I'd say here is a decent area where we'll see a pullback down to the $380 range.
Perhaps Tesla will be subject to correction after battery day but likely it will flare up again before 27 October, because of the earnings.
I think that this stock is very strongly traded on event based occurrences (with many inexperienced traders as well joining the "party") and indeed is overvalued, but it will take some time fore we see a very serious crash. Perhaps after earnings, it will be time for shorting with big returns? What do you think?
