The S&P 500 has erased its losses for 2025, turning positive for the year after a significant rally driven by technology stocks, particularly Nvidia. The index closed 0.8% higher on Tuesday, marking a recovery from a year-to-date low of -15% in April to a gain of +0.50%. The Nasdaq Composite also saw a strong performance, rising 1.7% on Tuesday, while the Dow Jones Industrial Average experienced a decline of 0.64%, losing 269.67 points due to a significant drop in UnitedHealth shares. The rally was fueled by a combination of factors including a surge in tech stocks, softer inflation data at 2.3%, and easing trade tensions between the U.S. and China. Nvidia's shares advanced 5.6% following news of a deal to supply 18,000 AI chips to Saudi Arabia, contributing to the broader market's upward movement. The positive shift in the S&P 500 reflects a broader market optimism amidst recent economic developments.
