The more interesting thing to consider is that Trump has said Elon will have an active role in his administration. How is he going to do that on top of everything else? How are Tesla investors going to feel about this?
I think for most of his business he already have other peiple he trust in charge of them. Its impossible to manage so many companies and he seens to spend more effort in Space X than Tesla, starking, etc...
The CEO of a company being one of most powerful people in government is excellent for Tesla investors. Much less so for the general population, as the conflict of interests is obvious.
Especially outside US - if next government will ignore world or start doing some serious harm (ie by being too friendly with putin), tesla drivers will be frowned upon universally and very few new sales can be expected, more like a lot of vandalism on cars.
I guess China is a gone market for tesla at this point.
