US stocks moved higher on Monday as investors welcomed a temporary easing of tensions between the United States and Iran, helping markets recover from a volatile weekend dominated by geopolitical uncertainty.
The Dow Jones Industrial Average rose roughly 300 points during afternoon trading, while the S&P 500 gained 0.8%. The Nasdaq Composite outperformed the major indexes with a 1.4% advance, supported by strength in large-cap technology shares.
The gains came despite sharp intraday swings as traders balanced improving geopolitical sentiment with lingering concerns about energy markets and the economic outlook.
Alphabet and Comcast Lead Market Gains
Technology stocks were among the strongest performers, led by Alphabet, which climbed more than 4% after officially joining the Dow Jones Industrial Average.
The move marked a milestone for Google's parent company and attracted renewed investor interest as index-tracking funds adjusted their holdings.
Comcast also posted strong gains, rising 7% after announcing plans to separate its media and technology operations into two publicly traded companies. The spin-off is expected to be completed within the next year and is intended to unlock shareholder value by allowing each business to pursue independent growth strategies.
Markets Respond to US-Iran Diplomatic Progress
Investor sentiment improved after the United States and Iran agreed on Sunday to pause hostilities and allow commercial vessels to move freely through the Strait of Hormuz following a weekend of military exchanges.
According to US officials, both sides agreed to "stand down for now" while technical negotiations continue under the broader memorandum of understanding aimed at ending the conflict.
The ceasefire followed US strikes on Iranian military targets in response to attacks on shipping infrastructure. President Donald Trump later confirmed that American and Iranian officials are scheduled to meet Tuesday in Doha, Qatar, to continue negotiations.
Although Trump warned that further military action remains possible if agreements are violated, investors viewed the return to diplomacy as a positive step toward reducing geopolitical risks.
Oil Prices Remain in Focus
Crude oil prices initially moved higher as traders assessed whether the ceasefire would hold.
Brent crude rose about 1.3% to around $73 per barrel, while West Texas Intermediate gained roughly 1.4% to trade above $70 per barrel before paring some of those gains later in the session.
Analysts noted that neither Washington nor Tehran appears eager to return to sustained military conflict, reducing fears of prolonged disruptions to global energy supplies.
Supreme Court Ruling and Jobs Report Take Center Stage
Markets also reacted positively after the US Supreme Court ruled that Federal Reserve Governor Lisa Cook would remain in office, rejecting efforts by the Trump administration to remove her.
While the court expanded presidential authority over several independent agencies, it specifically preserved the Federal Reserve's independence, reassuring investors concerned about potential political interference in monetary policy.
Looking ahead, attention is shifting toward Thursday's June nonfarm payrolls report, which has been moved forward because US markets will be closed Friday for the Independence Day holiday.
The employment report is expected to play a significant role in shaping expectations for future Federal Reserve policy. Strong labor market data could reinforce the central bank's cautious stance on interest rates, while weaker figures may strengthen expectations for policy easing later this year.
For now, easing geopolitical tensions, resilient technology stocks, and optimism surrounding upcoming negotiations helped Wall Street begin the holiday-shortened week on a positive note.
