I'm not sure it will take that long. China backing down on their tariffs was a sign that the tariff war isn't going well for them either. The difference between the 2 countries is we know how they've affected the US whereas China restricts information from getting out.
Yeah, if you bought Tesla in 2017 (like I did), you're still probably up 20X. A 20% drop isn't anything to be concerned over.
