Adding to investor concerns, Musk's growing engagement in Washington's political sphere, marked by his recent tweets on government spending and the shutdown, could be unsettling. Additionally, Tesla faced a challenge with its European EV sales, which fell by nearly 30% year-over-year in November, highlighting the need for strong December sales in China and the U.S. to meet its Q4 target of approximately 515,000 vehicles, against Wall Street's forecast of 503,000. Despite these concerns, Tesla's stock fluctuations on Friday may simply reflect natural market behavior, as it has climbed about 76% this year.
