Tesls's next earnings date is Oct 21. I believe Tesla might have sold quite well in this period in China, but I am really doubtful about sales in the rest of the world. Some slightly bad recent publicity might also affect Q4 sales (roof blown off on the highway, suspension failures at high speed).
The bottom line is that I really like this company, within one year they will probably surpass 600, but I think that their next two quarterly reports will not be so good. They need to get their quality control together, and also ramp up efficiency at their repair centers, it's unacceptable to wait 2+ months due to a damaged rim or bumper panel (Europe).
My investment strategy will focus on what happens in the days right before earnings report. If the stock drops below the black "earnings report line", I will close my positions and short it (very small amount, it's highly risky to short Tesla).
