US stocks closed mixed on Monday as semiconductor stocks fell and Treasury Secretary Scott Bessent announced "Operation Economic Outcast" — a series of expanded sanctions aimed at squeezing Iran.
The S&P 500 (^GSPC) declined by about 0.3%, and the tech-heavy Nasdaq Composite (^IXIC) dropped roughly 0.8%.
The Dow Jones Industrial Average (^DJI) rose by 0.3% as the lone index in the green after the major indexes posted weekly declines.
Investors rotated out of tech names as semiconductor stocks came under pressure. Sandisk (SNDK), Micron (MU), and other memory chip stocks dropped following a report over the weekend that Nvidia (NVDA) plans to raise prices for some of its AI servers.
Stocks were little changed, however, after Bessent outlined a plan to "sever every economic lifeline" to Iran and isolate the nation. In a press conference on Monday afternoon, Bessent detailed expanded sanctions on Iran and on any country that deals economically with it, stating that countries with ties to the regime will be "removed from the US dollar system."
