Stock market today: Wall Street rises at the start of a holiday-shortened week

Stocks shook off a choppy start to finish higher Monday, as Wall Street kicked off a holiday-shortened week.

The S&P 500 ended 0.7% higher after having been down 0.5% in the early going. The Dow Jones Industrial Average also recovered from an early slide to eke out a 0.2% gain. The tech-heavy Nasdaq composite rose 1%.

Gains in technology and communications stocks accounted for much of the gains, outweighing losses in consumer goods companies and elsewhere in the market.

Semiconductor giant Nvidia, whose enormous valuation gives it an outsize influence on indexes, rose 3.7%. Broadcom climbed 5.5% to also help support the broader market.

Walmart fell 2% and PepsiCo slid 1%.

Japanese automakers Honda and Nissan said they are talking about combining in a deal that might also include Mitsubishi Motors. U.S.-listed shares in Honda jumped 12.7%, while Nissan ended flat.

Eli Lilly rose 3.7% after announcing that regulators approved Zepbound as the first and only prescription medicine for adults with sleep apnea.

All told, the S&P 500 rose 43.22 points to 5,974.07. The Dow gained 66.69 points to 42,906.95. The Nasdaq rose 192.29 points to 19,764.89.

Traders got a look at a new snapshot of U.S. consumer confidence Monday. The Conference Board said that consumer confidence slipped in December. Its consumer confidence index fell back to 104.7 from 112.8 in November. Wall Street was expecting a reading of 113.8.

The unexpectedly weak consumer confidence update follows several generally strong economic reports last week. One report showed the overall economy grew at a 3.1% annualized rate during the summer, faster than earlier thought. The latest report on unemployment benefit applications showed that the job market remains solid.

A report on Friday said a measure of inflation the Federal Reserve likes to use was slightly lower last month than economists expected. Worries about inflation edging higher again had been weighing on Wall Street and the Fed.

The central bank just delivered its third cut to interest rates this year, but inflation has been hovering stubbornly above its target of 2%. It has signaled that it could deliver fewer cuts to interest rates next year than it earlier anticipated because of concerns over inflation.

Inflation concerns have added to uncertainties heading into 2025, which include the labor market's path ahead and shifting economic policies under an incoming President Donald Trump.

"Put simply, much of the strong market performance prior to last week was driven by expectations that a best-case scenario was the base case for 2025," said Brent Schutte, chief investment officer at Northwestern Mutual Wealth Management Company

Treasury yields rose in the bond market. The yield on the 10-year Treasury rose to 4.59% from 4.53% late Friday.

European markets closed mostly lower, while markets in Asia gained ground.

Wall Street has several other economic reports to look forward to this week. On Tuesday, the U.S. will release its November report for sales of newly constructed homes. A weekly update on unemployment benefits is expected on Thursday.
