Global Tech Sell-Off Tests Markets as Fed Signals Higher Rates

A sharp rotation out of AI and chip stocks is rattling world markets even as the Dow notches fresh record highs, while a hawkish Fed flips its 2026 rate outlook.

A volatile week for global equities as AI valuations come under renewed scrutiny.

Global stock markets are caught in a tug-of-war this week. On one side, the Dow Jones Industrial Average has been notching fresh intraday records, touching 52,655.66 on optimism around industrials, healthcare and financials. On the other, a sharp sell-off in AI, chip and memory stocks has dragged the Nasdaq Composite down for four straight sessions, its longest losing streak since February, as investors reassess whether years of AI-driven valuations have run too far ahead of fundamentals.

A Market Split Down the Middle

The divergence has been stark. On June 25, the Nasdaq slipped 0.46% to 25,358.60 while the S&P 500 was essentially flat at 7,357.49, yet the Dow climbed 0.14% to 51,920.62, an all-time closing high. A day later, broader weakness spread, with the S&P 500 down roughly 0.75% and the Nasdaq off about 1.25%, even as small-cap stocks in the Russell 2000 bucked the trend, gaining 0.71%. Strategists describe this as a rotation: money once concentrated in AI infrastructure names is shifting toward industrials, consumer staples and energy companies whose valuations were not built on assumptions of limitless AI revenue growth.

Capital is rotating out of richly valued AI names and into steadier, profit-generating sectors.

The Fed's Hawkish Pivot

Underpinning the volatility is a notable shift from the Federal Reserve. At its June 17 meeting under new Chair Kevin Warsh, the FOMC voted unanimously, 12-0, to hold the federal funds rate at 3.5%-3.75%. But the accompanying projections told a different story: the median policymaker now expects rates to end 2026 higher than they started, a reversal from March when the median forecast still implied a cut. Seventeen of eighteen officials judged inflation risks to be tilted to the upside, with the median 2026 core inflation projection rising to 3.3%, well above the Fed's 2% target. Half the committee now sees at least one rate hike before year-end, a meaningful change in tone that has rippled through rate-sensitive growth stocks.

Valuation Jitters Spread Globally

The unease has not stayed contained to Wall Street. Asian markets saw a sharper reaction: South Korea's Kospi index fell as much as 8% intraday, triggering a temporary circuit-breaker halt before closing down 5.8%, as investors in semiconductor and memory-chip suppliers tied closely to the AI buildout took the brunt of the selling. Reports also point to roughly $400 billion in value erased from SpaceX's private valuation amid the broader reassessment of high-growth technology bets, alongside continued scrutiny of stretched multiples across cloud infrastructure and chipmaking names.

Analysts caution that elevated valuations leave little room for disappointment in upcoming earnings.

Corporate Crosscurrents

Individual company news has added to the noise. Micron Technology shares jumped more than 15% after a stronger-than-expected earnings report, briefly lifting sentiment toward memory-chip makers, while Apple shares fell roughly 6% following an announcement of price increases on MacBook and iPad devices. Index-level changes are also in motion: Verizon is set to be removed from the Dow Jones Industrial Average ahead of the June 29 open, to be replaced by Alphabet, reflecting how benchmark composition continues to tilt further toward technology and communication-services weight even as some investors rotate away from the sector.

Single-stock swings underscore how sentiment can shift quickly even within a broader market rotation.
