The Nasdaq Composite extended its losing streak to a fourth consecutive session on Thursday, declining 0.46% as a sharp selloff in Apple shares eclipsed a stellar earnings report from memory chip giant Micron Technology. Apple plunged more than 8% — its worst single-day drop in months — dragging the tech-heavy index down 580 points and snapping a nine-week winning streak. The divergence highlighted growing investor anxiety over the sustainability of the artificial intelligence trade, even as one of its key beneficiaries delivered blockbuster results. Micron surged 16.6% initially on fiscal third-quarter revenue of .05 billion, beating estimates of .85 billion, but gains evaporated as Apple's supply chain warnings triggered broader tech rotation. The session underscored a market increasingly focused on near-term execution risks rather than long-term AI narratives.
What Happened
Apple shares tumbled 8.3% to close at 98.45, marking their seventh straight daily decline and the steepest single-day drop since April 2025. The iPhone maker warned that higher memory chip costs would pressure margins, announcing price increases across several product lines. Micron Technology, a key Apple supplier, had reported fiscal Q3 revenue of .05 billion — up 84% year-over-year — and guided Q4 revenue above consensus at .8 billion. Despite the blowout, Micron shares reversed a 16.6% intraday gain to close down 9%, illustrating the market's skepticism. The Nasdaq 100 fell 0.5%, with Nvidia down 3.2%, AMD down 2.8%, and Broadcom down 2.1%. The Philadelphia Semiconductor Index (SOX) slid 2.4%. European markets bucked the trend, with the Stoxx 600 rising 0.3% as chip equipment makers ASML and ASM International gained on Micron's strong outlook. The Cboe Volatility Index (VIX) jumped to 18.5, its highest level in three weeks.
Why It Matters
Thursday's action reveals a market recalibrating its AI expectations. For months, megacap tech has rallied on the premise that infrastructure spending would accelerate indefinitely. Micron's results confirm demand is real — data center revenue doubled — but Apple's warning signals that cost pressures are migrating downstream. When the world's most valuable company raises prices because memory is too expensive, it suggests the AI supply chain is straining. This matters globally: semiconductor equipment orders from Asia to Europe now hinge on whether hyperscalers maintain 2025 capital expenditure pace. The nine-week win streak's end also removes a key technical support narrative. With the Nasdaq below its 21-day moving average for the first time since May, trend-following strategies may accelerate selling. For investors, the lesson is clear: AI beneficiaries are not immune to cyclical margin compression, and concentration risk in the Magnificent Seven remains elevated.
What's Next
All eyes turn to next week's inflation data and Federal Reserve commentary. The May PCE price index, due Friday, will test whether the disinflation trend holds — a hot print could renew rate-hike fears that initially sparked the tech rout. Micron's Q4 guidance implies memory pricing strength through year-end, but Apple's margin warning suggests end-demand elasticity has limits. Earnings from Nike and FedEx will provide consumer and logistics sector reads. Technically, the Nasdaq 18,500 level — the 50-day moving average — becomes the next critical support. A break could trigger systematic selling from volatility-targeting funds. As one strategist noted, "The AI trade isn't over, but the easy money has been made. From here, stock picking matters more than theme chasing."
