US Stock Market Today: Live Updates 28.04.2026
The S&P 500 and Nasdaq 100 closed at record highs Monday, driven by optimism over upcoming tech earnings from Apple, Microsoft, and Meta. Gains came despite a 2% surge in WTI crude prices after President Trump canceled Iran talks, heightening tensions at the Strait of Hormuz. Qualcomm’s reported collaboration with OpenAI and MediaTek boosted AI-infrastructure stocks. The strait remains effectively closed, raising energy supply concerns.
