Sunday focus turns to Fed policy and AI-chip supply

U.S. markets were closed for the weekend, leaving QQQ and SPY unchanged from Friday's close. Treasury Secretary Scott Bessent said the Fed was unlikely to shrink its balance sheet quickly even under chair nominee Kevin Warsh. AI-chip supply developments included Samsung's expected HBM4 deliveries to Nvidia, tight T-glass capacity, and a multi-year, multi-billion-dollar agreement between STMicroelectronics and AWS. In Japan, Sanae Takaichi's election victory and President Trump's endorsement accompanied a record Nikkei move above 57,000 and a weaker yen.
