U.S. stocks rebounded Tuesday, breaking a three-session losing streak as a sharp recovery in semiconductor shares outweighed persistent Middle East tensions. The Dow Jones Industrial Average added roughly 360 points, the S&P 500 climbed about 0.9% to reclaim the 7,490 level, and the Nasdaq Composite led the major indexes with a 1.3% gain — a turnaround for a market that had shed 2.9% on the Nasdaq the prior week, when the Philadelphia Semiconductor Index briefly slipped into bear-market territory.

Chips lead the rebound. The advance was powered by the same group that dragged the market lower a week ago. Micron Technology surged 12.6% and Nvidia rose about 2%, the latter also disclosing a stake in AI-cloud provider Nebius. Smaller names rode the wave, with Aehr Test Systems up 27% and Cerebras Systems climbing roughly 17%. The tone was set overnight in Asia, where benchmarks in South Korea and Taiwan each gained more than 2.5%, led by Samsung Electronics and Taiwan Semiconductor.

The AI capex question comes to a head. This week delivers what many are calling the most comprehensive single-week test yet of whether the AI spending boom is producing real returns. Alphabet and Tesla both report Wednesday after the close, followed by Intel on Thursday. The central question — when a roughly $180 billion capital-expenditure cycle translates into proportional revenue — has been building for three years. Alphabet, which raised its full-year 2026 capex guidance to $180–$190 billion, enters off 22% revenue growth last quarter, with Google Cloud margins in focus. Tesla arrives on a record 480,000-plus delivery quarter but faces margin questions. IBM limps into its Wednesday report after a 25% single-day plunge last week, its worst session on record.

Corporate movers. General Motors kicked off the week’s marquee reports Tuesday morning, beating second-quarter expectations and reinforcing a steadier read on consumer demand. The day’s standout was Utz Brands, up nearly 90% after agreeing to be taken private by Germany’s Intersnack Group in a deal valued at about $2.9 billion. The broader season has started strong: of the roughly 50 S&P 500 companies reporting through the weekend, 88% topped estimates, per FactSet, which puts blended Q2 earnings growth at 24.7%.

Geopolitics and commodities. The rebound unfolded against a tense backdrop. The U.S. has now carried out roughly 10 consecutive nights of strikes on Iran, though reports that mediators are pushing for a 10-day ceasefire helped cool oil after Monday’s spike. Adding regional strain, Yemen’s Houthis declared a “maritime embargo” against Saudi Arabia — a potential threat to Red Sea crude flows. Brent crude held near $91 a barrel, while gold jumped more than 1.5% to about $4,071 an ounce on safe-haven demand and a firm dollar.

Trade policy in the mix. U.S. Trade Representative Jamieson Greer told CNBC he expects “to see some action soon” on tariffs, following a report that the White House is preparing new levies against dozens of countries ahead of the expiration of the current 10% global tariff. The comments came a day after President Trump imposed a 50% tariff on most Canadian goods — a thread with direct implications for the cross-border businesses JBiz readers track.

Beneath the surface. For all the day’s optimism, breadth stayed narrow: even at session highs, a slim majority of stocks were lower, underscoring how much of the gain rested on a handful of large-cap chipmakers. The macro calendar offers little fresh guidance before the Federal Reserve’s July 28–29 meeting, leaving corporate earnings as the dominant catalyst. With megacap results due through the week, investors will soon learn whether Tuesday’s rebound reflects renewed conviction — or simply a pause in an unusually jittery tape.
