On March 11, according to Wall Street News, Tesla CEO Elon Musk said in an after-hours interview on Monday that he was running his business with "great difficulty" while fulfilling his duties as head of the Department of Government Effectiveness (DOGE) in the Trump administration. In the interview, Musk revealed that the DOGE team has more than 100 members and may expand to 200 in the future. It is currently saving more than $4 billion per day and is expected to achieve an overall savings of $1 trillion. He said DOGE has penetrated almost all departments of the US government, is recruiting from the financial and technology fields, and plans to serve in the Trump administration for another year. On the same day, Tesla's stock price plunged more than 16% during the day and closed down more than 15%, setting the worst intraday performance since September 2020. As of the close, Tesla has fallen more than 54% from the record high set in December 2023, and its market value has evaporated by about 800 billion US dollars. Analysts believe that the uncertainty of the Trump administration's tariff policy and the damage to brand perception caused by Musk's political remarks are the main reasons for the decline in the stock price. Since Musk took office in the Trump administration, Tesla's stock price has fallen for seven consecutive weeks, the longest decline cycle since the company went public in 2010.
