The US stock market opened weak today, with all three major indices showing slight declines. The Dow Jones Industrial Average fell by 0.15%, the S&P 500 index decreased by 0.18%, while the tech-heavy Nasdaq Composite Index slid by 0.36%. This trend is related to the recently released PCE (Personal Consumption Expenditures) data meeting market expectations.

It is worth noting that the stock price of Chinese e-commerce giant Alibaba has risen against the trend, soaring 7.65% at the opening. This increase is mainly attributed to the company's latest financial report, which shows a year-on-year revenue growth of 2% in the first quarter, and a remarkable 12% year-on-year growth in instant retail business revenue in the first half of the year, demonstrating the company's resilience in the current economic environment.

On the other hand, the leading chip company NVIDIA continued its fall from the previous trading day, opening down 1.36%. This may reflect investors' ongoing concerns about the valuation of high-tech stocks.

The current market landscape highlights investors' efforts to seek a balance between economic data and corporate performance. While some technology companies are performing strongly, overall market sentiment remains cautious. As more economic indicators are released, investors will closely monitor the potential impact of this data on the Federal Reserve's future monetary policy direction.
