Major US stock indices closed sharply higher Monday, driven by investor optimism following a historic peace deal between the United States and Iran. The S&P 500 rose 1.65%, the Dow Jones Industrial Average gained 0.92%, and the Nasdaq 100 surged 3.06%, led by technology stocks.

Reasons for the Rally

The strong rally was triggered by the announcement of a peace deal between Washington and Tehran, which eases geopolitical tensions in the Middle East and reduces the risk of oil supply disruptions. Technology stocks benefited particularly, with AMD, Marvell Technology, and Datadog posting notable gains. Energy stocks such as Exxon Mobil and Chevron also rose despite lower oil prices.

Sector Performance

Technology stocks led the gains, with the Nasdaq rising over 3%. Semiconductor stocks performed strongly, with AMD, Qualcomm, Texas Instruments, and Lam Research all advancing. Energy stocks were mixed, with Exxon and Chevron rising while ConocoPhillips and Schlumberger declined.

Futures Moves

In the futures market, June S&P 500 futures rose 1.68%, while June Nasdaq 100 futures gained 3.06%, reflecting sustained optimism.

What It Means for Investors

The deal removes a major source of geopolitical uncertainty, potentially supporting a short-term rally in stocks, especially in technology and energy sectors. However, investors should monitor the deal's details and its impact on oil prices and interest rates.
