Wall Street closed out the second quarter on a high note Monday, with all three major indexes finishing firmly in positive territory as a combination of renewed confidence in the AI trade and welcome geopolitical relief gave investors reason to buy. The Dow Jones Industrial Average climbed to a fresh all-time high, capping what many are calling the best quarter for U.S. stocks in years.
What Moved Markets
The Dow Jones Industrial Average (DJI) gained 306.63 points, or 0.6%, to close at a record 52,182.74. The S&P 500 added 86.41 points, or 1.2%, finishing at 7,440.43. The tech-heavy Nasdaq Composite surged 522.53 points, or 2.1%, to end at 25,820.14. Six of the S&P 500’s eleven sectors closed in positive territory, led by Communication Services (+3.1%), Consumer Discretionary (+2.7%), and Technology (+1.7%). The CBOE Volatility Index, Wall Street’s fear gauge, slipped 4.1% to 17.65, reflecting easing anxiety across the market.
Two forces drove Monday’s gains. First, AI-related and mega-cap technology stocks staged a meaningful rebound after struggling in recent sessions, with investors returning to positions they had pared back on recession and valuation concerns. Second, the market breathed a collective sigh of relief after the United States and Iran formally agreed to halt all hostilities and guarantee safe passage for commercial vessels through the Strait of Hormuz. The U.S. had struck Iranian military targets over the weekend following a breakdown in a June 17 ceasefire memorandum, briefly raising fears of further escalation. Sunday’s agreement to stand down removed an overhang that had weighed on sentiment and energy markets alike. No major economic data was released Monday, leaving the geopolitical and technology narratives to dominate the session.
The session also marked the final trading day of Q2 2026, and the results for the quarter are striking. Chip stocks in particular posted a stunning run, and Wall Street enters earnings season with high expectations — analyst firm FactSet is forecasting S&P 500 earnings growth of 22% for Q2, which would mark the second consecutive quarter of 20%-plus growth. Markets will be closed this Friday in observance of Independence Day, making this a holiday-shortened week with fewer catalysts ahead.
Notable Movers
Alphabet (GOOGL) was one of the session’s biggest stories, surging 4.8% on its first day of trading as a component of the Dow Jones Industrial Average. The addition of Alphabet to the 30-stock index marks a significant shift in the composition of one of Wall Street’s most-watched benchmarks, and the debut drew fresh buying interest from index-tracking investors.
Applied Materials (AMAT) led semiconductor stocks higher, jumping 10.1% as chip names broadly rebounded from a rough stretch. The move reflected a broader reassessment of the AI infrastructure buildout, with investors again piling into the companies supplying the hardware behind the trend. The VanEck Semiconductor ETF (SMH) was among the stronger performers on the session.
AeroVironment (AVAV) surged more than 16%, making it one of the day’s biggest individual gainers. The defense drone manufacturer has drawn renewed investor attention against the backdrop of ongoing geopolitical tensions and elevated defense spending globally, and Monday’s move added to a notable run for the stock in recent months.
Circle Internet Group (CRCL), the stablecoin and crypto infrastructure company that recently completed its public offering, fell roughly 13%. The stock has faced selling pressure as broader cryptocurrency markets pulled back, with Bitcoin declining more than 2% on the session.
Looking Ahead
With Q2 now in the books and earnings season approaching, investors will shift focus to what companies actually delivered — and, more importantly, what they say about the road ahead. Major banks are set to kick off reporting in the coming weeks, followed by a wave of technology names whose guidance will be scrutinized for signs of AI spending momentum or any cracks in demand. The Iran situation bears continued watching; while Sunday’s agreement brought relief, the fragility of prior ceasefires in this conflict means traders will remain alert to any flare-ups. For now, though, the bulls head into the holiday weekend with a record Dow and a quarter that exceeded most expectations.
