US stocks experienced an upswing on Monday as the markets largely dismissed worries that the recent US strike on Iran might disrupt tanker traffic from the Persian Gulf or escalate regional tensions. The S&P 500, the Dow Jones, and the Nasdaq 100 each rose by more than 0.5%. Over the weekend, US forces targeted Iranian nuclear infrastructure following President Trump's previous dismissal of an immediate attack. In response, Iran threatened aggressive retaliation and its parliament supported blocking the Strait of Hormuz. Despite these tensions, oil tankers continued their operations through the area, and crude oil prices moderated, alleviating fears of rising inflation. Meanwhile, Tesla's shares surged over 7% after the company launched its first fleet of driverless taxis over the weekend. Additionally, AMD shares increased by more than 2% following an upgrade from Melius Research. However, ExxonMobil and Chevron saw their gains diminish as WTI futures shifted to a significant decline.
