NEW YORK — Stocks rose on Wall Street Monday to open what’s expected to be a relatively calm holiday week.

Gains were broad. Technology companies and banks did much of the heavy lifting. Industrial companies also gave a strong push to major indexes.

The S&P 500 rose 43.99 points, or 0.6%, to 6,878.49. The Dow Jones Industrial Average rose 227.79 points, or 0.5%, to 48,362.68. The Nasdaq composite rose 121.21 points, or 0.5%, to 23,428.83.

Smaller company stocks did particularly well. The Russell 2000 index outpaced other major indexes with a 1.2% gain.

The gains also helped major indexes push further into winning territory for the month as a choppy December nears its end. Technology companies, especially those focused on artificial intelligence, have been the main force behind the market’s oscillations. The direction of AI-related stocks will likely determine whether the market closes out December with gains or losses.

“If a Santa Claus rally does kick in this year, St. Nick’s gift bag will likely need to be full of positive tech sentiment,” wrote Chris Larkin, managing director of trading and investing at E-Trade from Morgan Stanley.

Nvidia, which has had a big role in driving the broader tech sector higher this year, rose 1.5%. JPMorgan was among the bigger winners in the banking sector with a 1.9% gain.

Uber rose 2.5% and Lyft rose 2.7% after announcing plans to bring robotaxi services to London next year.

Paramount Skydance rose 4.3%. The company sweetened its hostile takeover bid for Warner Bros. Discovery with an “irrevocable personal guarantee” from Larry Ellison, founder of Oracle and father of Paramount CEO David Ellison. He is putting up billions of dollars to back the deal as part of the latest move in Paramount’s bidding war against Netflix.

Warner Bros. Discovery rose 3.5% and Netflix fell 1.2%.

Dominion Energy fell 3.7% after the Trump administration said it is pausing leases for five large-scale offshore wind projects. They include Dominion’s Coastal Virginia Offshore Wind project.
