Why did TSLA fell by 4% today, now?

Tesla's stock decline of 4.81% today can be attributed to a combination of factors:

1. Sales Decline in China and Europe: Tesla has experienced a 15% year-over-year drop in China-made electric vehicle deliveries for May, with shipments falling by 15% compared to the previous year. In addition, sales in key European markets such as Britain, Germany, and Italy have also fallen for the fifth consecutive month. These regional sales declines could be a result of increased competition, market saturation, or changes in consumer preferences.
2. Political Controversies: The end of Elon Musk's formal advisory role to the U.S. President Donald Trump has raised uncertainty about the future of his cost-cutting initiative and could signal broader tensions between Musk and Republican lawmakers. These political controversies can lead to negative sentiment among investors and contribute to stock price declines.
3. Market Conditions and Competition: The broader market conditions and competition within the electric vehicle sector could also be influencing factors. For example, Tesla's main rival, BYD, saw global passenger vehicle sales rise 14% in May, which might be attracting some of Tesla's potential customers.

In summary, Tesla's stock decline today is likely a result of a combination of sales decline in China and Europe, political controversies, and market conditions and competition.
