There is zero reasonable argument for uncertainty about this supposed production cut, unless one is actually happening due to either severe supply chain constraints caused by COVID impacts or some kind of unannounced line upgrade which somehow didn't leak in advance this time, and both of those seem pretty unlikely considering how these things have worked in the past for Tesla China.
There are backlogs in countries around the world, including nearby Australia, and China just set a massive new record for domestic sales from Giga Shanghai in the first two months of a quarter. Demand issues? Come on.
Moreover, merely seven weeks ago, Elon reaffirmed in direct response to demand questions "I can't emphasize enough, we have excellent demand for Q4, and we expect to sell every car that we make for as far in the future as we can see. So, the factories are running at full speed..." Then later he said this:
I can't help but notice that zero news media outlets have even mentioned this explicit, unambiguous guidance from the earnings call. A reasonable publication would quote this comment as I have just done and then explain that the report from the "anonymous source familiar with the matter" directly contradicts it, which means either:
1) The report is false
2) Elon was blatantly committing fraud on the call
3) Plans have changed substantially in the past seven weeks for some reason
Did any journalist do this? No, not that I've seen.
