Summary · why it matters

U.S. stocks were mixed, with the Dow Jones Industrial Average rising to a one-week high while the Nasdaq 100 fell to a one-week low, as a selloff in chipmakers and AI-infrastructure stocks weighed on the broader market. The iShares Semiconductor ETF dropped more than 2%, with Sandisk down over 8% and ARM Holdings down over 7%, following a 6% plunge in South Korea's Kospi Index driven by sharp losses in SK Hynix and Samsung Electronics. UnitedHealth Group jumped 4% after reporting second-quarter adjusted earnings per share of $6.38, well above the consensus of $4.89, and raising its full-year adjusted EPS estimate to $19.50 to $20.00, while Abbott Laboratories surged more than 11% after lifting its full-year adjusted EPS forecast to a range of $5.45 to $5.60. Stronger-than-expected U.S. economic data, including a drop in weekly initial jobless claims to a 10-week low of 208,000 and a Philadelphia Fed business outlook survey rising to a 4.5-year high of 41.4, pushed the 10-year Treasury yield up 3 basis points to 4.58%. WTI crude oil prices rose nearly 1% after the U.S. launched fresh airstrikes on Iran and struck a sanctioned Iranian oil tanker in the Persian Gulf, with President Trump pledging to intensify bombardment until Iran stops attacking ships in the Strait of Hormuz.
