Lead Story#

The artificial intelligence trade faced a global reckoning as the semiconductor sector headed for its worst month on record, but late-day market narratives pivoted sharply when Iran launched a surprise ballistic missile attack on U.S. forces in the Middle East. The abrupt end to a temporary ceasefire sent U.S. crude surging over 4% and left stock futures flat as investors braced for the geopolitical fallout.

Markets & Economics#

The broader market experienced a stark rotation as the Dow Jones Industrial Average surged more than 500 points on solid blue-chip earnings, while the Nasdaq Composite logged its fifth consecutive losing session. The tech-heavy weakness was driven by a brutal semiconductor sell-off that began in Asia, where SK Hynix plunged 10% after its Q2 revenue and profit missed expectations despite record milestones. The contagion spread to U.S. chipmakers, with the SOX index tracking toward a historic monthly decline amid fears of AI “circular financing” and Chinese DUV breakthroughs. Meanwhile, bond markets and Fed funds futures are pricing in a likely rate hold, though Chairman Kevin Warsh faces a delicate press conference balancing the inflationary risks of surging oil and heavy tech capex.

Business & Earnings#

Coca-Cola was a standout, popping roughly 5% after topping Q2 expectations and raising its full-year organic revenue forecast to 5% on the back of resilient global demand. Boeing shares advanced as the planemaker generated a surprise $631 million in positive free cash flow, softening the blow of a wider-than-expected loss driven by a $280 million charge on the Air Force One program. In the payments space, Visa announced it is cutting 7% of its workforce—about 2,600 jobs—to streamline operations and reinvest in growth areas as AI reshapes its internal workflows. Elsewhere, Johnson & Johnson struck a landmark $5.5 billion deal to resolve tens of thousands of ovarian cancer lawsuits tied to its talc products.

Investing & Commentary#

Wall Street analysts are sounding the alarm on the AI infrastructure trade, with Jim Cramer explicitly warning investors using margin to sell data center stocks immediately and rotate into “stair-step” names like Costco and Walmart. Hyperscaler skepticism is peaking ahead of this week’s earnings, pushing Microsoft short interest to a decade high of 92 million shares as investors question the ROI on hundreds of billions in AI capex. Echoing the shift toward defensive positioning, Morgan Stanley advised buying high-quality, free-cash-flow generators with solid dividends, singling out Colgate-Palmolive and SLB.
