The read-through is direct for Nvidia, AMD, Apple, Broadcom, Qualcomm, Intel, Applied Materials, Lam Research, KLA, ASML, Samsung Electronics, SK hynix, and the entire US chip sovereignty thesis.

United Airlines Beat Earnings but the $6B Fuel-Cost Guide Means Airlines Are Now Trading Oil, Not Capacity
United Airlines Holdings reported Q2 2026 adjusted EPS of $1.99 (vs $1.88 est.) on $17.67B revenue (vs $17.61B est.), but guided to $9-$11 full-year EPS and warned that jet fuel costs could add nearly $6 billion vs the start of the year. July jet fuel prices at major U.S. airports are up 34% MTD through Tuesday per Argus/Airlines for America data. Q2 fuel costs rose 84% YoY to $2.3B. UAL traded down 2.37% to close at $120.97 after-hours. The trade is no longer about premium revenue or international expansion - it is about how much of the $6B fuel hit airlines can pass through, and which carrier survives the worst-case fuel tape.
