Stock Market Recap — Aug 23, 2026
US futures dip amid mounting AI costs and financing strains
Risk appetite softened into the US evening as mounting AI funding needs, Canadian trade retaliation and firmer Treasury yields outweighed selective corporate catalysts. The mix favored memory suppliers and tanker operators while pressuring diluted China internet shares, long-duration assets and tariff-sensitive exposures. • Alibaba/AI: Alibaba launched a $10.2 billion discounted placement after heavy AI spending drove quarterly cash outflow; Michael Burry disclosed that he had exited the stock. • Nvidia/Memory: Nvidia reportedly committed $7 billion to license Poolside technology and invest in the startup, while rising memory costs pointed to AI-server price increases above 15%. • Trade/Markets: Canada announced dollar-for-dollar tariffs on US goods from Sept. 8. The Canadian dollar slid as much as 0.5%, while Nasdaq 100 futures fell 0.2%. • Rates: The 10-year Treasury yield rebounded to 4.73% amid deficit concerns, AI-related corporate borrowing, inflation risks and uncertain Federal Reserve policy. • Oil/Shipping: Saudi Arabia rerouted crude around Africa and through Egypt after Houthi threats disrupted Yanbu exports, more than doubling some Asia-bound voyage distances. • Autonomous Driving: Amazon’s Zoox began charging Las Vegas riders and operating purpose-built robotaxis in San Francisco after US regulators authorized up to 5,000 vehicles.
Weekly Recap — Stocks retreat after Gulf tensions lift oil and yields
Risk appetite weakened overall as Gulf supply fears, resilient US activity and hawkish Federal Reserve minutes kept oil and long-end yields elevated. The tape was sharply selective: energy, crypto and biotech outperformed, while semiconductors, duration-sensitive growth and tariff-exposed companies lagged; weekend US-Canada retaliation added a negative setup rather than defining the trading week. • Oil/Rates: Brent climbed from above $90 to above $94 before WTI finished the week up 6.9%, as shipping attacks and Iran’s refusal to reopen Hormuz deepened supply concerns. The 10-year yield reached 4.75% and the 30-year touched 5.314%; Treasury buybacks briefly helped, but strong regional data and Fed minutes reviving hike risk reversed much of the relief. • Chips/AI Credit: The Philadelphia Semiconductor Index fell more than 5% Tuesday as yields surged. Nvidia gained support from OpenAI capacity plans and eased Chinese H200 restrictions, but rising memory and server costs, large debt packages and weekend funding headlines underscored leverage risks across the AI buildout; Micron benefited from DRAM inflation. • Crypto/Biotech: Bitcoin surged nearly 20% through Thursday and topped $79,000 Friday, lifting Coinbase and Strategy. Moderna soared 177% after its Merck-partnered melanoma vaccine succeeded in a late-stage trial, with Merck and BioNTech also rallying. • Consumer/Trade: Walmart fell after its slowest US comparable-sales growth in six years, while Ross raised guidance. Canada’s weekend tariff retaliation increased pressure on autos, industrials and other cross-border exposures.
