S and P 500 stocks delivered a powerful rally Tuesday, with the broad-market index reaching a fresh all-time intraday high as investors responded to strong corporate earnings, falling oil prices and hopes for progress in talks involving the Strait of Hormuz.
The S and P 500 climbed 1.8% and finished at a record level, marking its first fresh high since June. The Nasdaq Composite performed even better, surging 2.5%, while the Dow Jones Industrial Average jumped 1,035 points, or 2%, to surpass its previous intraday record.
S and P 500 Hits Historic High on Powerful Rally
Technology stocks led the advance, with the information technology sector rising approximately 4%. Palantir Technologies was the standout performer, soaring 29% after reporting better-than-expected second-quarter results. The company’s performance was supported by a sharp increase in U.S. commercial revenue and growing demand for artificial intelligence sovereignty tools.
Palantir CEO Alex Karp described the company’s results as “otherworldly,” reflecting strong momentum in its artificial intelligence business. The stock was on pace for its best single-day performance in more than two years.
Chipmakers also regained ground after a difficult July. Micron Technology advanced 7%, while Marvell Technology jumped 14%. The move suggested that investors were becoming more comfortable with continued spending by major technology companies on data centers and AI infrastructure.
Explosive Earnings Lift Major Dow Components
Caterpillar provided another major boost to the market. Shares of the industrial giant rose 6% after the company reported adjusted earnings of $8.17 per share on revenue of $20.54 billion. Analysts had expected earnings of $6.20 per share and revenue of $19.34 billion.
Caterpillar also increased its revenue growth guidance and said full-year tariff costs should come in at the lower end of its previous forecast. Management pointed to strong equipment demand as the nationwide AI data-center construction boom supports industrial activity.
Financial stocks gained about 1%, led by a more than 3% increase in Goldman Sachs. Industrials and materials each added nearly 2%, showing that Tuesday’s rally extended beyond the largest technology companies.
- Palantir Technologies surged 29% after a strong earnings report.
- Caterpillar climbed 6% following an earnings beat and improved guidance.
- Micron Technology rose 7%, while Marvell Technology advanced 14%.
- Goldman Sachs gained more than 3% as financial stocks moved higher.
Oil Prices Drop as Hormuz Deal Hopes Grow
Energy markets also played an important role in the stock market advance. West Texas Intermediate crude fell about 5% to roughly $75 per barrel, while Brent crude declined approximately 5% to near $79.
The decline came after Treasury Secretary Scott Bessent said the United States was in talks with Iranian officials and that a deal could potentially be reached Tuesday or Wednesday to reopen the Strait of Hormuz. He said the agreement could provide freedom of movement for commercial shipping.
The Strait is a crucial global energy route, and any reopening would ease concerns about supply disruptions, shipping delays and rising transportation costs. The possibility of hundreds of vessels leaving the Persian Gulf also raised expectations that oil prices could fall further.
Still, uncertainty remains high. Earlier reports indicated that Iran had denied plans for direct negotiations with Washington, while U.S. officials continued to describe diplomatic discussions as ongoing. Investors are therefore treating every development as potentially market-moving.
Strong Earnings Keep Investor Confidence Alive
The latest gains came during an especially strong earnings season. According to FactSet, more than 84% of S and P 500 companies that have reported results have exceeded analyst expectations.
That record has helped offset concerns about inflation, elevated bond yields and geopolitical risk. Macquarie Group strategist Thierry Wizman said the market’s recent strength suggested investors were focusing heavily on corporate results and improving confidence around technology spending.
Other companies also attracted attention. McDonald’s rose more than 1% after reporting adjusted earnings of $3.38 per share, above the $3.32 expected by analysts, although revenue slightly missed forecasts. Merck gained after beating estimates and raising its full-year revenue guidance. Pfizer also reported stronger-than-expected quarterly results.
However, not every market signal was positive. Job openings edged lower in June to 7.36 million, below the 7.6 million expected by economists. The data pointed to a gradually cooling labor market, while the Federal Reserve continues to monitor inflation and economic activity.
What the Record Means for Investors
The latest S and P 500 rally shows how quickly market sentiment can change when earnings remain resilient and geopolitical pressures appear to ease. Technology leadership, AI investment and stronger industrial demand are giving investors several reasons to remain optimistic.
At the same time, risks have not disappeared. Inflation remains above the Federal Reserve’s 2% target, Treasury yields are elevated and the future of U.S.-Iran negotiations is uncertain. A renewed disruption in the Middle East could quickly push oil prices higher and pressure stocks.
For now, Wall Street is focused on earnings momentum, lower energy costs and the possibility of a diplomatic breakthrough. Those forces helped create one of the market’s strongest sessions of the year.
