Why did semiconductor stocks surge despite SpaceX and AMD missing sky-high expectations?

Semiconductor stocks surged because Asian markets followed Wall Street's record close, with the Kospi rising 4.0% led by SK Hynix and Samsung, reflecting strong investor focus on AI-related capital expenditure; the gains occurred despite SpaceX and AMD underperforming relative to extremely high market expectations — SpaceX due to concerns over $18 billion capex (nearly $16 billion on AI) straining cash flow, and AMD due to an 8.8% after-hours drop even though its sales and outlook 'topped the Street', as the market judged the results insufficient to justify its 142% year-to-date share gain.

What is driving the recent retreat in oil prices, and what are its broader market implications?

Oil prices retreated — Brent fell 1.5% to $78.24 — due to concerns about potential oversupply, fueled by higher-than-expected Gulf oil flows and speculation that even a modest reopening of the Strait of Hormuz could tip the market into oversupply; this retreat eased pressure on bonds, pushing 10-year Treasury yields down to 5.60% and reducing market expectations for Federal Reserve tightening, with implied odds of a September hike falling from 67% to 57%.
