Overnight Developments
Asian Tech Rout Spreads to US Futures; Kospi Crashes 10% — CNBC / Bloomberg
A semiconductor-led selloff swept across Asia overnight. South Korea’s Kospi plunged roughly 10%, with SK Hynix and Samsung each down more than 12%, as investors repriced AI/chip valuations and questioned the sustainability of the capex cycle. The weakness cascaded into Japan (Nikkei -3.65%), Hong Kong (Hang Seng -1.82%), and US futures. This is a valuation/sector reset rather than a discrete policy shock — no new tariffs, central bank surprises, or geopolitical escalations were reported.
Affected sectors: Semiconductors, Technology, AI infrastructure, Electronics
Futures & Pre-Market
| Index | Futures | Change |
|---|---|---|
| S&P 500 | 7,434.50 | -0.96% |
| NASDAQ | 29,805.25 | -1.90% |
| DOW | 51,845.00 | -0.47% |
Watchlist Context
No individual watchlist names were flagged above the 3% alert threshold pre-market, but the rout hits our semiconductor- and AI-heavy names hardest. Watch NVDA, TSM, SMCI, INTC, and the mega-cap tech complex (AAPL, AMZN, GOOG, META) at the open. Apple’s Tim Cook has flagged that memory-cost surges make price increases unavoidable — a thread worth tracking as DRAM supply tightens.
International Markets
Asia led the decline: Nikkei 225 -3.65%, Hang Seng -1.82%, Shanghai Composite -1.40%. Europe is softer but more contained — DAX -1.16%, FTSE 100 -0.39% — suggesting the pressure is concentrated in tech/semis rather than a broad global risk-off.
What to Watch at Open
Expect a tech-led gap down with the NASDAQ underperforming the broader market. Watch whether semiconductors and AI mega-caps stabilize after the open or extend the Asian losses, and whether the selling stays contained to tech or spreads to cyclicals.
