No its not.
Things haven't been going as well as they were with Elon at the helm.
What is different?
The price of Tesla stock
So Tesla stock price is different, but the company is functionally unchanged. I dont see that as being brought down. If you're worried about your wallet, dont buy TSLA.
The price of Tesla stock is different every minute of every business day, the same as the price of any other stock. Sometimes down, sometimes up.
What tweet, by who, do you have in mind.
