I'm not sure combo of 5K and China GF announcement is fully baked into current SP. Mostly but maybe not fully.
However, what I don't think may be baked in is Tesla opening up the order flood gates to M3 Dual and Performance variants
to any and all reservation holders. It has only been two or three weeks since the best Q3 and Q4 earning projections were based on assumptions of 5K per week sales of LR Rear Motor at it's projected gross margin. Now preference has redirected to building as many higher margin M3s as possible. A cherry on the sundae might be announcing a really large number of reservation holders ordering these higher margin cars and handing Tesla $2500 apiece. That combo well might push SP to ATH.
The consensus of the Street is that Tesla will miss the 5k goal, again. Even bulls are cautioning that failing to achieve 5k doesn't matter that much after all. Probably 4-4.5k?
The consensus of TMC bulls seems a slight miss to a slight above the 5k target. To TMC bulls, 5k would be a relief, high 5k (5.5k or higher) would be definitely a surprise (other direction would be less than 4.5k).
As to the China GF, not much media activities - since the early June sharehold meeting, there has been only one report with Shanghai factory or China gigafactory in the title - by non other than our lovely Lora Kolodny on cnbc. Another one from usatoday, one short video from bloomberg, none from wsj. Considering how important of overseas expansion, I would say this is extreme low media exposure to the incoming China GF announcement. Probably all FUDed and fixating eyeballs on the phantom bankwupcy?
Mr. market is hard to predict - FUDesters and Chinos & co even make it harder. How retail investors think often does not mean much. The $389 ATH has been much like pump and dump, feuled by irrational exuberance of retail bulls. How insitutional investors think and act is the main driving force behind the SP movement in the med term. In the long run, of course, it's all about how much money a company makes - or rather we're all dead.
