Today, US stocks opened lower across the board, with the Dow Jones Index, S&P 500 Index, and Nasdaq Index falling by 0.53%, 0.95%, and 1.48%, respectively, indicating overall market weakness. Notably, Tesla's net profit in the second quarter failed to meet market expectations, causing its stock price to drop sharply by 8.63% after opening, making it one of the focal points of today's stock market. Meanwhile, Alphabet, the parent company of Google, also attracted market attention as its stock price fell by 4.69%. This was due to the company's second-quarter performance exceeding expectations while announcing plans to increase capital expenditure within the year. These series of market fluctuations reflect the current complex and uncertain economic environment, requiring investors to remain cautious and closely monitor subsequent market developments.
