Dow Falls 200+ Points Amid Big Tech Surge Lifting Nasdaq, S&P 500

On Monday, U.S. stock markets showed mixed results with the Dow Jones Industrial Average falling over 200 points while the Nasdaq Composite and S&P 500 experienced modest gains. Amazon emerged as a key market driver, rallying approximately 4% following its announcement of a $38 billion deal with OpenAI to provide cloud services for AI workloads, which positively influenced the tech-heavy Nasdaq. Nvidia also contributed significantly to market gains with a 2.2% increase, reinforcing its position as a strong performer in AI-related stocks. Despite overall market breadth being weak, with more than 400 S&P 500 stocks declining, large technology companies like Amazon, Nvidia, and Palantir Technologies buoyed the indices. The consumer discretionary sector was notably supported by gains in Amazon and Tesla, while healthcare stocks and materials sectors faced declines. The market's focus remains on AI advancements and the potential impacts of economic policies like tariffs and interest rates amid ongoing uncertainty due to limited economic data.
