Major U.S. stock indices have surged to record levels as optimism around a potential U.S.-Iran peace deal continues to lift market sentiments. The Dow Jones, S&P 500, and Nasdaq each posted all-time highs, driven by strong earnings reports from companies like Dell and a broader tech sector rally. Investors are closely monitoring updates on the ceasefire extension in the Mideast, which has contributed to rising oil prices amid easing inflation concerns. The continued growth in AI spending also adds to positive market dynamics, further propelling the indices upwards. Following significant gains, analysts remain hopeful about sustained momentum in the markets.
