I think he meant "keeping TSLA where it is".

Tesla's sales have suffered, yes, and Elon's image is a significant contributor to that, besides all the reasons directly related to the cars themselves.

But Tesla's stock price is still stuck in irrational heights, not even remotely justifiable by the company's performance.

It just seems that people reconsider purchasing a physical object way quicker than they reconsider a stock investment. Maybe because the stock investment, especially in TSLA, is considered more like a gamble - "as long as others also think that this stock will skyrocket, even just because they think that others like me think it will skyrocket - as long as that's the case, I'm good with buying shares".
