Markets rally on Iran peace hopes and upbeat tech earnings

Stocks rose on Wednesday as optimism about a possible US–Iran peace deal and a robust tech earnings season boosted sentiment. The Dow climbed about 1%, the S&P 500 and Nasdaq gained, and oil slid on news of potential progress. AMD and Super Micro Computer led a wave of advances after strong guidance, Disney beat on earnings, and the broader market benefited from a high rate of positive earnings surprises (roughly 85% of S&P 500 results). ADP data showed private payrolls rising, signaling labor-market resilience, while all top-level sectors were expected to show year‑over‑year earnings growth for the first time in years.
