The results are being closely watched for further clues on U.S. consumer spending. 🤖 Alibaba AI Investment #BABA is in focus after quarterly net profit declined 75%, while capital expenditure increased 75%, reflecting continued heavy investment in AI infrastructure. 🧬 Moderna & Merck Remain in Focus #MRNA / #MRK remain on investors' radar following Wednesday's major melanoma-vaccine trial announcement. Moderna shares are pulling back after their sharp previous-day rally. 🏭 Corporate Earnings #COTY is under pressure following weaker guidance, while #DE is gaining after raising its annual profit forecast. 🏦 Treasury Yields & Buybacks The U.S. Treasury has increased planned long-term bond buybacks to at least $4 billion per operation. Although the intervention initially helped ease long-term yields, Treasury yields have moved higher again, keeping borrowing costs and fiscal concerns in focus. 🛢️ Oil & Geopolitics Brent crude is trading around $94 a barrel as tensions surrounding Iran remain elevated. Higher oil prices could add to inflation pressure and complicate the Federal Reserve's interest-rate outlook. 🌏 Global Markets Asian markets are mixed, with South Korean equities benefiting from SK hynix's buyback announcement, while investors continue to assess semiconductor valuations, AI spending and global interest-rate risks. 🎯 Market Theme Rising Treasury yields + elevated oil prices + AI/memory volatility + economic data.
