The Dow Jones Industrial Average closed above the 52,000 mark for the first time on Monday, driven by a broad market rally and a strong debut from Alphabet as a new index member.
The Dow gained 306.63 points, or 0.59%, to finish at 52,182.74. The S&P 500 rose 1.18% to close at 7,440.43, while the Nasdaq Composite climbed 2.07% to end at 25,820.14.
Alphabet was among the standout performers, jumping nearly 5% in its first trading session as part of the Dow. Meanwhile, Comcast surged 4.4% after announcing plans to split its media and technology businesses into two separate publicly traded companies, with the separation expected to be completed within a year.
Chip stocks also staged a strong comeback. The VanEck Semiconductor ETF (SMH) gained more than 3%, reversing earlier losses. Key semiconductor names posted sharp gains, with Astera Labs rising around 16%, KLA up roughly 12%, and Applied Materials climbing nearly 11%.
The rally comes as Wall Street enters a shortened trading week, with U.S. markets scheduled to close Friday for Independence Day.
Geopolitical developments also remained in focus. The U.S. and Iran agreed on Sunday to pause hostilities and allow commercial shipping through the Strait of Hormuz, easing concerns over global trade disruptions after a tense weekend of military exchanges.
Tensions had escalated after U.S. strikes targeted Iranian military sites in response to attacks near the Strait of Hormuz. Donald Trump later warned of further action, signaling continued pressure on Iran despite the temporary pause.
Oil prices moved higher as traders weighed whether the ceasefire would hold and reduce risks to global energy supply. Brent crude rose 1.61% to settle at $73.15 per barrel, while West Texas Intermediate (WTI) gained 2.2% to close at $70.75.
