U.S. stocks rebounded on Monday, ending a five-day losing streak, as AI chip investments and media spin-offs boosted market sentiment.

(1) The S&P 500 Index rose by 0.5% on Monday, potentially ending its previous five-day losing streak, while the Dow Jones Industrial Average gained about 195 points and the Nasdaq Composite Index climbed 0.8%. The technology sector led the gains, driving an overall market rebound. (2) Samsung Electronics and SK Hynix announced that they will invest nearly $520 billion in South Korea to build a new chip manufacturing hub. This news boosted AI-related stocks, while Comcast's share price surged 23% on plans to spin off its media business, making it the standout performer of the day. (3) Despite an escalation in US-Iran tensions over the weekend, which pushed Brent crude oil above $73, the stock market was not significantly dampened. Institutions believe oil traders are too optimistic about the timeline for supply recovery in the Persian Gulf; if the recovery is slow or tensions escalate again, oil prices still face significant upside risk. (4) With trading hours shortened this week due to the holidays, investors will closely monitor developments in Iran and US employment data—including job vacancies, layoff reports, and Thursday’s June nonfarm payrolls report—to assess labor market conditions and their impact on the Federal Reserve's policy path.
