- Dow Jones jumped more than 500 points on July 28, 2026 — with one outlet specifying a rise of over 530 — as oil prices slid and investors rotated out of chip stocks.
- Micron, Marvell, and Nvidia declined alongside other chip stocks during the session, pulling the tech-heavy Nasdaq down even as the S&P 500 and Dow rallied, per Barron's and WSJ coverage.
Why it matters: The sharp Dow-versus-Nasdaq split on July 28, 2026, shows investors trimming exposure to AI-driven semiconductor names — Micron's 755% year-to-date run stands in stark contrast to its single-day decline here — and rotating into energy-sensitive Dow components as crude prices eased.
