Stock Market Midday, July 27: Dow Edges Higher as Nvidia Drop Weighs on Nasdaq

U.S. stocks were mixed at midday as lower oil prices and easing geopolitical tensions supported the Dow, while AI valuation concerns and weakness in Nvidia pressured the Nasdaq. The Dow rose modestly, the S&P 500 slipped, and the Nasdaq fell as investors rotated away from tech ahead of a heavy earnings week featuring Microsoft, Meta Platforms, Apple, and Amazon. RTX and SAP stood out on strong earnings, while Reddit rallied on upbeat expectations for its upcoming report. Oil’s nearly 7% drop after reports of a pause in U.S.-Iran strikes boosted risk sentiment, but the article notes that markets remain vulnerable to volatility from the Federal Reserve meeting, inflation pressures, and large-cap tech capex scrutiny. Overall, the piece frames the session as a sector rotation and macro-driven pause rather than a broad selloff.
