Stock Market Today, July 9: AI Chip, Technology Stocks Rally, Overcoming Ceasefire Worries
AI hardware and optical-communication gains helped steady major U.S. indexes after war-driven swings, today, July 9, 2026.
Overview
As of roughly noon E.T., the S&P 500 (SNPINDEX:^GSPC) rose 0.56% to 7,524.39, the Nasdaq Composite (NASDAQINDEX:^IXIC) climbed 0.78% to 26,073.17, and the Dow Jones Industrial Average (DJINDICES:^DJI) added 0.24% to 52,473.28 as AI chip strength helped markets stabilize after war‑driven volatility.
Chip and optical‑communication names, including Marvell Technology (NASDAQ:MRVL), Corning (NYSE:GLW), Coherent (NYSE:COHR), and Lumentum (NASDAQ:LITE), were among the day’s notable gainers amid sector‑wide demand for communications chips. However, high-valuation AI behemoth Palantir (NASDAQ:PLTR) extended its 29% decline year-to-date, dropping about 4% so far today.
Details
Despite the U.S.-Iran ceasefire being paused for now, and the market facing a growing drumbeat of analysts saying we might be in “bubbly” territory, stocks surged higher today, buoyed by the strength of AI and semiconductor stocks. In addition to a handful of analyst upgrades of semiconductor stocks, SK Hynix's upcoming U.S. ADR offering is estimated to be more than seven times oversubscribed, indicating that immense investor appetite remains in the space.
