Stock Market Today, Nov. 9: Markets Rally as Semiconductor Gains Lift Nasdaq

On November 9, stock markets experienced a notable rally, driven by gains in the semiconductor sector that lifted the Nasdaq Composite to 25,253, marking a 2.74% increase. The S&P 500 also rose 2.35% to 7,550, recovering from its weakest weekly performance since April 2025. The Dow Jones Industrial Average saw a 2.15% gain, reaching 52,390.

Gold prices climbed 1.74% to $4,138.25, while the 10-Year Treasury yield edged 0.02% higher to 4.88%. All sectors witnessed positive performance, with industrial stocks leading gains at 4.59%. Basic materials and consumer cyclical stocks also fared well. Nvidia's shares dropped over 4% after the company initiated an internal investigation into CEO Jensen Huang's personal relationships.

Conversely, Cloudflare surged nearly 10% as investors favored broader AI infrastructure. Tesla's stock rose over 5%, as its robo-taxis expanded into more cities. The market's rebound today erased some of the losses from the previous week, buoyed by dip buying and falling oil prices. Investors are closely monitoring leadership and security risks at Nvidia, as well as the potential impact on the AI sector.

Constellation Energy's shares jumped over 10% after beating earnings estimates and upgrading its full-year guidance. AI-infrastructure stocks faced a slump last week due to concerns over potential slowdowns in data center construction resulting from the Democratic Party's success in the U.S. midterm elections. However, today's results have boosted the sector, including NRG Energy and GE Vernova.

Market resilience today is encouraging, but the recent sell-off and Nvidia's internal probe remind investors to remain cautious about portfolio risk, especially exposure to AI-related stocks.
