Tesla stock sunk as much as 8% after President Donald Trump fired a new shot at Elon Musk. Trump said Musk had government subsidies than "any human being in history" in a post on Truth Social. The pair's feud was reignited by more criticism from Musk over Trump's tax bill.

Tesla investors ought to be at least a little concerned that things may get worse. The shares plunged 14% on June 5 when the Musk and Trump relationship spectacularly fell apart in an escalating war of words on social media.

Second-quarter vehicle deliveries are forecast to see one of the company’s biggest ever year-over-year declines and the Senate version of Trump’s budget bill phases out EV tax credits.
