Among the losers are also chip manufacturer Nvidia, down 3.0 percent, and software giant Microsoft, minus 1.1 percent.
Thus, the technology-heavy Nasdaq composite index also took a hit and fell 0.8 percent. The broad S&P 500 index swung slightly down, minus 0.1 percent, while the Dow Jones industrial index went strong, plus 0.9 percent.
Tuesday was tough for Tesla's part. Musk, previously an advisor to Trump and leader of the newly established efficiency organization Doge, has called Trump's proposal for a state budget "insane". The proposal includes, among other things, reduced subsidies for both the purchase and manufacture of electric cars.
Trump has said that Musk without subsidies would need to "go home to South Africa" and suggests in social media posts that Doge should investigate Tesla.
According to sources for the news agency Bloomberg, Musk himself will take over the responsibility for Tesla's sales in the USA and Europe, which is the company's weakest market at present.
