Global Tech Sell-Off Intensifies
Global equity markets experienced a sharp sell-off led by technology and semiconductor stocks on June 23, 2026. South Korea’s Kospi plunged about 10%, driven by drops exceeding 12% in SK Hynix and Samsung. European benchmarks fell, with the Stoxx 600 down roughly 1% and its Technology index off about 3%. U.S. Nasdaq 100 futures fell ~2.7% and semiconductor names and ETFs posted steep losses (SOXX down ~6.2%; Intel, Micron, AMD and Nvidia all lower). SpaceX shares extended earlier declines. Market commentators including Wedbush’s Dan Ives framed the sell-off as a potential buying opportunity, while Tom Hulick of Strategy Asset Managers said liquidity and earnings momentum reduce the risk of a market catastrophe. Micron’s upcoming earnings were cited as a near-term catalyst.
Widespread declines in major technology and semiconductor stocks can affect capital allocation, advertising demand and valuations across the tech and ad-tech ecosystem; near-term catalysts (e.g., Micron earnings) could further influence market and industry dynamics.

Tech Sell-Off Shakes Markets; SpaceX Loses One-Third
A broad sell-off in technology stocks on June 23, 2026 pushed major indices lower as investors reacted to rising rate expectations and concerns about increased corporate spending on AI. European and US futures fell — the DAX slid about 400 points intraday and Nasdaq 100 futures fell up to 3%. Chipmakers and semiconductor-equipment firms were especially weak ahead of several earnings reports this week; Micron is due to report, and Qualcomm is holding an investor event. SpaceX’s market value dropped from a near‑record high of almost $3.0 trillion on June 16 to about $2.03 trillion, a decline of roughly one-third since the peak. Market participants cited expectations that the Fed under new chair Kevin Warsh may raise rates, higher energy costs and tariffs, and the sustainability of debt-funded AI investments as drivers of the sell-off.
Asian tech stocks tumble; SoftBank down 10%
Asian technology stocks extended a regional sell-off driven by semiconductor weakness and follow‑through from a weak U.S. session. SK Hynix, which earlier plunged more than 15% after missing analysts’ estimates despite record quarterly profit and revenue, fell about 9.7% on Aug. 6, 2026; Samsung Electronics was down roughly 6.1%. Japanese chip names including Tokyo Electron, Kioxia and Advantest also declined, while U.S. chip peers were mixed to weak and Chinese internet stocks in Hong Kong outperformed. Market drivers cited deleveraging in Korea, trimming of frothy AI gains and heightened volatility in semiconductor‑heavy markets. Analysts including J.P. Morgan and S&P Global remained constructive, saying the AI investment cycle and defense spending should sustain tech demand and noting tech‑equipment PMI strength overall.
Global Chip Sell-Off and Cerebras Earnings Shake Markets
CNBC’s Morning Squawk (published 2026-06-24) reports a broad sell-off in global chip stocks led by Micron, which experienced one of its largest one-day declines. Micron is set to report earnings after the bell. AI chipmaker Cerebras, which recently went public, reported its first post-IPO quarterly results: revenue rose 92% year-over-year but management issued weaker gross-margin guidance (expected core gross margin 36–38% vs. 46.5% prior), and the stock was down about 10% in premarket trading. The note also covers geopolitical comments on the Strait of Hormuz, Federal Reserve leadership selection dynamics, and the PGA Tour’s announced format changes slated for 2028.
