US Stocks Mixed Ahead of Key Economic Reports

US stocks experienced mixed movements as markets prepared for a crucial Federal Reserve interest rate decision and numerous Big Tech earnings reports. Initially, stocks rose with the Dow Jones Industrial Average, S&P 500, and Nasdaq Composite all showing gains driven by favorable earnings in the semiconductor sector. However, later sessions saw the Nasdaq tumble due to declines in tech stocks such as Nvidia and Microsoft, reflecting investor caution. The Federal Reserve is expected to maintain current interest rates but might hint at potential rate cuts in September, influencing market sentiment. Key labor market data and earnings reports from major companies like Apple, Microsoft, Meta, and Amazon are highly anticipated, with any misses likely to trigger further market volatility. Treasury yields fell in response to mixed job growth data, adding another layer of complexity to the market's outlook.
