US Stock Markets Decline Amid AI Sector Concerns and Rising Inflation Data

US stock markets showed mixed to negative performance amid concerns over AI sector valuations and rising inflation. The Dow Jones experienced both gains and sharp declines, while the Nasdaq and S&P 500 generally fell, with Nasdaq facing its steepest monthly drop since March 2025. Nvidia's stock dropped despite strong earnings, fueling fears of an AI bubble and job losses. Elevated inflation data, including a higher-than-expected Producer Price Index, added to market uncertainty and volatility.
