U.S. stocks experienced a slight decline on Monday, with the S&P 500 dropping 15.84 points or 0.22%, closing at 7,110.22 points. This dip followed a three-week streak of gains and was influenced by renewed tensions between the U.S. and Iran, casting doubt on a recent ceasefire. Although Iran is contemplating attending peace talks in Pakistan, the closure of the Strait of Hormuz over the weekend raised concerns about supply disruptions. Despite this, U.S. crude oil prices surged, with a 6.87% increase to $89.61 per barrel, benefiting the energy sector. The Nasdaq Composite and Dow Jones also saw minor declines of 0.25% and 0.01%, respectively. The CBOE Volatility Index, known as Wall Street's fear gauge, rose, reflecting market uncertainty. As companies prepare to report earnings this week, including major players like Lockheed Martin and Tesla, investors are keen to assess the impact of geopolitical tensions on corporate performance and the broader economy.
