Wall Street Rebounds as Earnings Season Outshines Middle East War Fears

Markets Find Their Footing Amid Global Uncertainty

Stocks climbed on Tuesday, July 22, supported by chipmakers, as investors looked past the latest developments in the Iran war to focus on corporate earnings. The Dow Jones Industrial Average rose 385 points, or 0.74%, to 52,224.64, while the S&P 500 advanced 0.89% to close at 7,509.20, and the Nasdaq Composite added 1.29% to end at 25,837.21. All three indexes broke three-day losing streaks.

The rebound comes after a bruising stretch for major U.S. indexes, which had faced a broad selloff driven by volatility in the technology sector and escalating tensions in the Middle East. The S&P 500 had fallen 1.6%, the Nasdaq Composite dropped 2.9%, and the Dow Jones Industrial Average declined 0.9% in the preceding week. The turnaround signals that, at least for now, corporate fundamentals are winning the tug-of-war with geopolitical fear.

Earnings Season Delivers a Strong Early Report Card

3M shares jumped more than 7% after the industrial giant's second-quarter earnings came in better than expected. General Motors also reported a beat on both the top and bottom lines for the second quarter, lifting its stock nearly 5%. The reporting period is off to a strong start.

Of the roughly 66 S&P 500 companies that have reported so far, nearly 88% have topped bottom-line estimates, according to FactSet. That's a remarkable early showing. Big names still set to report this week include Alphabet, IBM, and Tesla — results that could either cement the rally or send markets back into retreat. Market participants will be watching earnings calls closely for guidance on consumer demand, advertising revenue, cloud growth, and artificial intelligence investment, all of which have become central themes for technology sector valuations in 2026.

The Shadow of the Middle East and Oil Prices

Tensions in the Middle East have escalated sharply in recent days, with the U.S. launching consecutive strikes on Iran. Oil prices soared amid the tensions, with Brent crude prices rising above $90 a barrel. The U.S.-Iran conflict raised concerns about possible disruptions to crude shipments through the Strait of Hormuz, and reports of American military casualties fueled fears of a broader regional conflict.

Escalating tensions in the Middle East sent oil prices to a five-week high, with Brent crude jumping over $92 a barrel even as mediators proposed a new 10-day ceasefire aimed at reopening the Strait of Hormuz. The latest increase has revived concerns that higher energy costs could contribute to another wave of inflation, potentially delaying interest rate cuts or prompting central banks to maintain restrictive monetary policies for longer. For everyday Americans, that means the prospect of continued pressure on everything from gas prices to borrowing costs.

AI Competition and the Road Ahead

Wall Street ended Monday's session lower after concerns resurfaced over whether the current pace of AI-related capital spending can be maintained. Semiconductor companies linked to artificial intelligence erased much of their earlier gains, with a sector index closing just 0.6% higher after previously climbing more than 3%. Investor sentiment was also affected by growing competition from new Chinese artificial intelligence models.

Separately, President Donald Trump signed executive orders imposing a 50% tariff on a broad range of Canadian exports, including paper, plywood, and hockey sticks, with the measures scheduled to take effect in 30 days. That adds yet another layer of complexity to an already volatile market environment. With a ceasefire in the Middle East still uncertain, oil prices elevated, and the AI spending debate far from settled, the strength of this week's remaining earnings reports may be the single biggest factor determining whether Wall Street's momentum holds — or fades.
