The AI-Capex Sell-Off
The S&P 500 recently reached a record near 7,845 before pulling back as doubts surrounding heavy artificial intelligence capital expenditures sparked a sharp technology sell-off. Following intense pressure across semiconductor and hardware infrastructure stocks, the S&P 500 closed around 7,660–7,665, trading roughly 2.3% to 2.4% below its record peak.
The tech-heavy Nasdaq Composite dropped 2.58% to close near 26,008...its worst single-day decline since June 5. On a weekly basis, the Nasdaq sank roughly 4% to 4.5%, marking its sharpest weekly slide in four months. By comparison, broad-market losses were milder: the S&P 500 fell about 1.2% to 2.0% on the week, the Russell 2000 slipped 1.66%, and the Dow Jones Industrial Average held relatively resilient (down 0.34% to end slightly positive on the week). The concentration of the sell-off underscores a distinct technology and semiconductor issue rather than a broad-market macroeconomic retreat.
Why CapEx Is the Fault Line
The semiconductor sector faced relentless selling, with chip stocks dropping for eight consecutive sessions....the longest losing streak for the group since 2008.
Semiconductors & Leverage: The VanEck Semiconductor ETF slid roughly 10% on the week (its worst weekly stretch since early 2025), while the 3x-leveraged Direxion Daily Semiconductor Bull 3X Shares (SOXL) dropped 12.7% in a single session.
Neocloud & Debt-Heavy AI Infra: High-leverage AI infrastructure providers bore severe hits as investors questioned whether massive capital outlays will generate sufficient cash flow to service debt. CoreWeave slid another 11.9% (down ~25% on the week), Nebius (
$NBIS) fell 12%, and Oracle gravitated toward 52-week lows under pressure from total debt near $51 billion.
Widespread Tech Weakness: Major chip and hardware names pulled back sharply, led by AMD (-5.95% to -8%), Intel (-5.79%), Micron (
$MU) (-5.63%), Sandisk (-8%), and Broadcom (
$AVGO) (-4.52%). Software stocks closely tracked the decline, with the iShares Expanded Tech-Software Sector ETF (IGV) dropping 4.8%. Demonstrating the breadth of the technology rout, 57 out of 60 semiconductor components in a Yahoo Finance basket closed lower Y'day.
