U.S. Stocks Open Higher on Monday as U.S.-Iran Ceasefire Boosts Risk Appetite, Dow Rises 1.2%

U.S. stock indices opened higher on Monday (July 27) following a ceasefire between the U.S. and Iran, which eased Middle East tensions and triggered a sharp drop in oil prices. The Dow Jones Industrial Average rose 622 points, or 1.2%, while the S&P 500 gained 65.74 points, or 0.89%, and the Nasdaq Composite climbed 275.67 points, or 1.1%.

Brent crude oil plummeted 6.7% to $90 per barrel, and the 10-year U.S. Treasury yield fell 3 basis points to 4.64%. The oil-price decline provided temporary relief to equity and debt markets, though investors remain cautious ahead of major tech earnings reports and the Federal Reserve's rate decision later this week.
