The U.S. stock market experienced a significant rally driven by a surge in technology stocks, particularly Nvidia and other big tech companies, helping the Nasdaq index rise sharply after weeks of turmoil. The S&P 500 increased by 1.2%, and the Nasdaq gained 1.9%, with Nvidia leading the gains with a 4% rise. This rally helped recover much of last week's losses, which were partly attributed to concerns over AI stock valuations reminiscent of the 2000 dot-com bubble. Meanwhile, the Dow Jones rose by 183 points, or 0.4%. Other notable tech winners included Palantir Technologies, which surged 8%, and Taiwan Semiconductor, which saw a 3.1% increase after reporting a 17% revenue rise in October. Despite the tech gains, the broader market faced pressure from ongoing uncertainties related to the U.S. government shutdown, which has caused delays in economic data and disruptions at airports. Health insurers like Humana and Cigna declined amid debates over healthcare tax credits. The shutdown has also impacted flight schedules and delayed economic reports, raising concerns about future Federal Reserve interest rate cuts, which are currently expected to continue to support economic growth. Corporate earnings reports provided some optimism, with Tyson Foods exceeding profit expectations due to higher meat prices. Overall, more than 80% of S&P 500 companies reported better-than-expected profits for the summer quarter, with strong forecasts for future results. International markets also rallied, with South Korea’s Kospi gaining 3% and chipmakers SK Hynix and Samsung Electronics rising 4.5% and 2.8%, respectively. The bond market saw the 10-year Treasury yield slightly decrease to 4.10%, reflecting cautious optimism amid economic uncertainties.
