U.S. stocks began August with a significant rally on Monday, propelling the Dow Jones Industrial Average to a closing record high. The surge was driven by signs of de-escalating tensions between the U.S. and Iran, which lowered oil prices and Treasury yields, alongside strong corporate earnings from the technology sector.
Diplomatic Shifts and Energy Impact
The market rally followed statements from President Donald Trump on Sunday, who indicated that talks with Iran to reopen the Strait of Hormuz would occur on Monday. Although Iran disputed that such talks were planned, Trump also stated over the weekend that he decided to hold off on new strikes against Iran following urging from regional allies. Brent crude prices sank 4.7% to $83.77, with crude prices overall settling down about 5%.
This decline in energy costs provided a lift to companies with high fuel expenses. United Airlines shares rose 5.8%, American Airlines climbed 5%, and Norwegian Cruise Line Holdings increased 6.6%. Conversely, the S&P 500 Energy sector was the worst performer of the session, dropping more than 1%.
The dip in oil prices also influenced the bond market. The yield on the 10-year Treasury fell to 4.68% from 4.75% late Friday, though this remains above the 3.97% level seen before the conflict with Iran. Art Hogan, chief market strategist at B. Riley Wealth in Boston, noted that the market reacts positively when the price of a barrel of oil and the 10-year yield move lower.
Tech Sector Gains and AI Outlook
Technology and communication services led the market’s upward trajectory. The communication services sector was the best performing of the 11 major S&P sectors, climbing more than 4%. This was bolstered by a 6% jump for Meta and a nearly 5% gain for Alphabet.
Amazon shares advanced 4.6%, and the company’s market capitalization surpassed $3 trillion for the first time following its earnings results last week. SpaceX shares jumped 5.6% ahead of its first quarterly results since going public, which are scheduled for Tuesday. SpaceX has traded below its $135 issue price for nearly three weeks since debuting in mid-June.
Jed Ellerbroek, a portfolio manager at Argent Capital Management, attributed the rally to investors becoming convinced of the return on investment for capital expenditure spending by big tech companies. Other AI-linked companies reporting this week include Advanced Micro Devices, Palantir, and data storage firms Western Digital and SanDisk.
Corporate Earnings and Economic Data
Broad corporate profits have remained robust. LSEG data shows a 29.3% growth rate from the 304 S&P 500 companies that reported earnings through Friday, with 85.2% of those companies exceeding analyst expectations. Additionally, FactSet reports that S&P 500 companies are on track to deliver spring earnings per share that are 47% higher than the previous year, which would mark the strongest growth since the spring of 2021.
Other notable market movements included:
- Boeing: Jumped 8%.
- Marriott International: Slumped 7% after forecasting third-quarter profits below expectations.
- Bristol Myers Squibb: Shares were little changed or edged up 0.2% following reports of preliminary merger talks with AstraZeneca, a deal that could create a drugmaker worth nearly $400 billion.
Market Indices and Federal Reserve Outlook
The rally helped the market recover from a volatile July, during which stocks struggled due to the U.S.-Iran conflict, interest rate paths, and concerns over AI trajectories.
