Stock Market Recap — Sep 28, 2026
Treasury yields hit 19-year high while front-month Brent holds above $106
Elevated oil prices and a sharp rise in Treasury yields set a difficult backdrop for equities, even as crude shipments recovered. Company news then drove divergent moves in technology, aerospace and biotech, with dealmaking extending into after-hours trading. • Rates/Oil: The 10-year Treasury yield touched 5.272%, a 19-year high, as investors weighed persistent inflation and further Fed tightening. The most-active Brent contract retreated toward $98 during US trading, but the front-month contract later stood at $106.41 despite recovering Middle Eastern exports. • Nvidia: Shares turned higher in premarket trading after the board added $150 billion to its buyback authorization, bringing the remaining total to $235 billion. • Software/AI: Meta fell 4% after launching a platform to sell AI tools to businesses. The S&P 500 software index lost nearly 2%. • Boeing: Shares fell 6.9% after the FAA delayed 737 Max 10 certification to assess whether a previously reported software glitch poses a flight-safety risk. • AMD Deal: AMD agreed to buy AI startup World Labs for $8.2 billion in stock, with a year-end close expected subject to approval. • Biotech: Summit Therapeutics rose 18% after hours after AstraZeneca agreed to invest $2 billion and expand their cancer-drug collaboration.
