I hate myself for reading this forum every day (but its such a guilty pleasure!) because by scrutinizing things so closely we are bound to lose perspective.
At 30,000 feet, its clear to me that TSLA is a total crap shoot until Q1 2020. That is the first quarter that Tesla is likely to be producing 10,000 cars, the original goal, the baseline sustained rate of production before the Model Y. Of course it could be even later than Q1 2020 if there are unanticipated delays in China or continued battery supply problems, but it is not going to be earlier than Q1 2020.
Anyone making short or long bets with a shorter time frame is pure gambling. Until then, a big SP drop is just as irrelevant as a big SP spike.
It seems highly unlikely to met that TSLA is trading at less than $350 in Q1 2020 if there is sufficient demand for those 10,000 cars. I'm long TSLA now because I believe that demand will be there, and I don't consider that gambling, I consider it an educated guess based on my perception of the competition, and the increasing general interest in electric cars, (I also assign real value to the possibility of robotaxis and Tesla Energy, but I'm not counting on the overall market to assign any value to that until it is closer to fruition).
