U.S. stock markets opened mixed as technology strength pushed the Nasdaq Composite up 0.87% and the S&P 500 0.39%, while the Dow Jones Industrial Average fell 0.11% on weakness in some blue-chip stocks. Large-cap technology companies have benefited from strong earnings and optimism over artificial intelligence developments, whereas industrial and financial shares remained more sensitive to interest-rate expectations and economic growth concerns. Investors are watching inflation data and Federal Reserve (U.S. central bank) commentary after markets recently priced in a higher likelihood of rate cuts later this year, though persistent inflation could change those expectations. Retail sales, the producer price index (measure of wholesale inflation) and earnings from major retailers are due later this week. The mixed open highlights the need for diversification and a focus on long-term fundamentals, while volatility may persist as markets respond to economic data and geopolitical developments.
