Wall Street stocks tumbled on Monday, as ongoing fears of artificial intelligence-related disruption and the fallout from Friday’s U.S. Supreme Court ruling sent investors fleeing from high risk equities

A broad selloff sent all three major U.S. stock indexes more than 1% lower by the closing bell, as risk appetite was dampened by a combination of persistent fears over potential disruption due to emergent artificial intelligence technology and Trump’s erratic statements on trade policy, which fueled much of the market volatility during the first year of the president’s second term.

Financial stocks  .SPSY  and software-related firms  .SPLRCIS  underperformed the broader market.

On Friday, the top court in the nation issued a 6-3 ruling that the US President overstepped his presidential authority by enacting reciprocal tariffs under an economic emergency law, a ruling that provoked condemnation from the president, who threatened a 15% temporary tariff on all imports, despite having reached trade agreements with many U.S. trading partners.

Gold prices advanced, benefiting from a flight to safety. A powerful winter storm buried much of the U.S. under more than 15 inches of snow and paralyzed travel in the Northeast. At airports in the New York City area, 89% to 98% of flights were canceled, according to Airlines  .SPCOMAIR  and travel/leisure-related stocks  .SPCOMHOTL  tumbled. Dow Transports  .DJT  also lagged.

With only 77 of the companies in the S&P 500 yet to post results, fourth-quarter earnings season has neared the finish line, a smattering of high-profile companies are expected to report this week, most notably vanguard artificial intelligence chipmaker Nvidia  NVDA.O  due on Wednesday. Home improvement rivals Home Depot  HD.N  and Lowe’s  LOW.N  are also on the docket, which is rounded out by Salesforce  CRM.N  and Universal Health Services  UHS.N .

Of the companies that have reported, 73% have beaten expectations, and analysts now expect aggregate year-on-year S&P 500 earnings growth of 13.9%, significantly higher than the 8.9% forecast as of January 1, according to LSEG data. According to preliminary data, the S&P 500  .SPX  lost 70.31 points, or 1.02%, to end at 6,839.20 points, while the Nasdaq Composite  .IXIC  lost 251.46 points, or 1.10%, to 22,634.61. The Dow Jones Industrial Average  .DJI  fell 810.81 points, or 1.65%, to 48,815.16.

Among the 11 major sectors of the S&P 500, financials were down the most, while consumer staples  .SPLRCS  enjoyed the largest percentage gain. The healthcare index  .SPXHC  advanced, with a boost from Eli Lilly  LLY.N  after rival Novo Nordisk’s  NOVOb.CO  obesity drug CagriSema underperformed Eli Lilly’s drug Zepbound in a head-to-head trial.

Among other movers, Domino’s Pizza  DPZ.O  surged after the fast-food chain’s fourth-quarter same-store sales beat Wall Street estimates. PayPal  PYPL.O  jumped following a Bloomberg report that the payments firm is attracting takeover interest.
