Today, the US stock market opened with a general pump trend. The Dow Jones Industrial Average rose by 0.36%, the S&P 500 Index rose by 0.34%, and the Nasdaq Composite Index also rose by 0.34%.

In terms of individual stocks, life sciences company Thermo Fisher Scientific performed well, with its stock price rising 11%. This was mainly due to its second-quarter earnings report exceeding market expectations. However, real estate technology company Opendoor Technologies faced a severe setback, with its stock price dropping 12.5%. At the same time, telecom giant AT&T was not spared either, with its stock price falling 5.18%.

Despite the overall positive trend in the market, investor sentiment seems to remain divided. Some analysts point out that certain investors may be waiting for clearer market signals before making investment decisions. At the same time, there are views that the current market may be experiencing some degree of short-term profit-taking pressure.

It is worth noting that the cryptocurrency market has also shown some positive trends, which may have a certain impact on related tech stocks.

Overall, the U.S. stock market today shows a characteristic divergence in the performance of the technology and communication sectors. Investors need to closely monitor the specific performance of each industry, as well as macroeconomic data and company earnings reports that may influence market direction.
