Background on Key Players and Context

On Monday, U.S. stock markets closed with gains, marking the first trading session of a shortened week due to Christmas holidays. The rally was partly driven by technology stocks, with nearly all 11 sectors of the S&P 500 experiencing advances.

Tech Sector Resurgence

The technology sector’s rebound began late last week, fueled by Micron Technology’s strong earnings forecast and a benign inflation report. This has kept the S&P and Dow Jones close to their all-time closing highs reached on December 11.

Market Performance at Closing Bell

At 14:36 GMT, the Dow Jones Industrial Average was up 180.3 points (0.37%) at 48,315.1 units; the S&P 500 gained 28.87 points (0.42%) to 6,863.4 units; and the Nasdaq Composite advanced 96.7 points (0.41%) to 23,404.3 units.

Nvidia’s Contribution to S&P 500

Nvidia’s stock price increase provided the largest boost to the S&P 500 index.

Reuters reported that Nvidia has informed its Chinese clients it plans to start shipping its second-most powerful AI chips to China before the Lunar New Year holiday in mid-February.

Other Notable Movements

Micron closed higher, along with other chip manufacturers. Preliminary data shows the S&P 500 gained 43.45 points (0.64%) to 6,877.95 points, while the Nasdaq Composite rose 121.21 points (0.52%) to 23,428.83. The Dow Jones Industrial Average advanced 222.65 points (0.46%) to 48,357.54 units.

Factors Driving Market Optimism

Optimism surrounding artificial intelligence, signs of resilience in the U.S. economy, and expectations of monetary policy easing have outweighed concerns about U.S. tariffs, contributing to the third consecutive year of gains for the three major U.S. stock indices. The S&P 500 has risen by 17% this year.

Trading Volume and Holiday Impact

Trading volumes were light, and they are expected to decrease further as holidays approach. U.S. stock markets will close at 18:00 GMT on Wednesday and remain closed on Thursday for Christmas.
