U.S. stocks finished a volatile July on a positive note as Amazon surged more than 15% following a blockbuster earnings report that signaled artificial intelligence investments are yielding profits, even as war in the Middle East drove oil prices higher and stoked broader inflation fears.
Big Tech Divergence: Amazon’s Cloud Surge Meets Apple’s Supply Crunch
The final trading session of the month delivered dramatic market-cap moves for Silicon Valley giants, underscoring the uneven toll of the ongoing artificial intelligence boom. Amazon led the market with a leap of 15.3% after reporting stronger profit for the latest quarter than analysts expected. The tech behemoth’s profits more than tripled from a year earlier, propelled by an acceleration of growth in its cloud computing business. Amazon increased its forecast for how much it will spend on investments this year.
Analysts pointed to the acceleration in cloud growth as a tangible sign that massive capital outlays in artificial intelligence are beginning to generate returns. Reinforcing that aggressive stance, Amazon increased its forecast for how much it will spend on investments this year. The bullish reaction mirrored Microsoft’s surge a day earlier, which marked its best day in nearly 18 years on similar signals of AI profitability.
By contrast, Apple fell 7.4% despite reporting stronger profit for the latest quarter than expected. Executive warnings that current-quarter revenue growth would miss expectations due to a component supply crunch—exacerbated by components getting vacuumed up in the AI boom—weighed heavily on investor sentiment. Meanwhile, semiconductor suppliers experienced wild intraday swings; Micron Technology swung from an early 6.4% gain to a 5.9% loss by the closing bell.
Energy Pressures, Gasoline Costs, and Bond Yield Volatility
Away from the tech sector, broader macroeconomic headwinds continued to trouble Wall Street. Ongoing conflict in the Middle East kept oil markets agitated, pushing the price of a barrel of Brent crude up 1.2% to settle at $87.93 after fluctuating between $72 and $102 throughout July.
The persistence of higher energy prices heightened inflation anxieties, sending shockwaves through the fixed-income market. The yield on the 10-year Treasury bond climbed to 4.71%, up from 3.97% before the war with Iran escalated energy costs. That sharp upward movement in long-term yields has pushed average U.S. mortgage rates to their highest level in a year, squeezing household purchasing power just as corporate earnings demonstrate underlying strength.
Federal Reserve Credibility and the Interest Rate Standoff
The bond market’s reaction compounded pressure on the Federal Reserve, which voted on Wednesday to leave its benchmark interest rate steady despite inflation remaining well above its 2% target. Federal Reserve Chairman Kevin Warsh vowed to return inflation to the central bank’s target but declined to offer guidance on future rate adjustments, maintaining that he prefers receiving unfiltered signals from financial markets.
“Without clarifying why action was or wasn’t taken already, it’s hard to see how statements about being committed to hitting its inflation target aren’t just a bluff.”

Analysts at Bank of America echoed those concerns in a recent report, stating that the Fed is facing a growing credibility problem.
They warned that unless incoming economic data shows a marked easing of price pressures, the central bank must use its September policy meeting to raise rates and establish a clear, consistent narrative.
Global Markets and Historic Volatility Abroad
International exchanges experienced even more pronounced turbulence. In South Korea, the Kospi index recorded the best single day in its history, soaring 17.9% on the back of surges by tech heavyweights Samsung Electronics and SK Hynix, which both jumped at least 26.8%. Even with Friday’s rally, the Kospi finished July down 22%.
Back on Wall Street, the major indexes managed to close the final session and the month on mixed foundations. The Dow Jones Industrial Average added 276.97 points, or 0.5%, to finish at 52,485.03, while the S&P 500 rose 52.09 points to 7,489.72, securing its first winning week in three despite a fractional loss for July as a whole. The Nasdaq composite climbed 251.68 points to 25,373.85, capping a turbulent period defined by corporate spending, geopolitical supply disruptions, and an intensifying debate over monetary policy.
