This Friday, the US stock market exhibited a complex trend, with major indices showing mixed performance. The technology sector faced pressure, leading to a slight decline of 0.3% in the Nasdaq index, while the Dow Jones Industrial Average rose slightly by 0.1%. Investors are closely monitoring inflation data and signals from the Federal Reserve, resulting in a cautious market atmosphere.

The field of artificial intelligence continues to demonstrate its strong momentum. NVIDIA's financial report exceeded market expectations, driving its stock price to surge by 8% in after-hours trading. The company's data center business is in high demand, with AI chip sales revenue doubling year-on-year, highlighting its leading position in the competition for AI technology.

At the same time, the global financial community is focused on the central bank annual meeting held in Jackson Hole. The speech by Federal Reserve Chairman Powell is highly anticipated, as he is expected to reiterate that the Fed's decisions will "depend on data" and leave room for a possible rate hike in September. However, the market generally believes that the start of the rate cut cycle may be delayed.

The government bond market has also seen significant changes, with the yield on 10-year U.S. Treasuries rising to 4.25%, reaching a new high in nearly two weeks. This trend reflects the market's expectations of persistently high interest rates, which may continue to put pressure on the real estate market.

The latest economic data shows that the core PCE price index rose 4.2% year-on-year in July, slightly above the expected 4.1%, indicating that inflationary pressures remain.

These complex economic indicators and market trends highlight the multiple challenges and opportunities currently facing the U.S. economy. Investors need to find a balance between inflationary pressures, technological innovation, and monetary policy to navigate the rapidly changing market environment.
