Stock Market Summary – November 24, 2025

The S&P 500 ended Monday 1.5% higher, driven by Alphabet’s 6% gain as investors were optimistic about the company’s advancements in AI. The Nasdaq Composite also saw a notable increase, jumping 2.7%, while the Dow Jones Industrial Average was up 187 points or 0.4%. AI-related companies, Broadcom and Micron Technology, surged 11% and 8%, respectively. Palantir Technologies and AMD jumped 6%, while Meta, Nvidia, and Amazon also advanced.

Despite the surge in AI-related stocks, some market participants voiced concern over over-reliance on a solitary sector for market growth. The S&P 500 slipped around 2% last week and has a November decline of about 2%. The Nasdaq, which fell nearly 3% last week, is down more than 3% for the month. The 30-stock Dow stumbled about 2% last week and is off more than 2% month to date. A lack of meaningful market catalysts leading up to the December policy meeting of the Fed could introduce more market volatility.
