South Korea's Kospi share index falls 7% and other Asian shares are mixed as oil prices surge
Asian stocks were mixed as oil prices rebounded and investors questioned AI investment plans. South Korea’s Kospi fell about 7%, led by SK Hynix after operating profit missed forecasts, and shares of Samsung Electronics also dropped. Chip-related stocks in Japan and elsewhere declined. Brent rose 3.1% to $84.58 and U.S. crude rose 3.6% to $82.14.
How this was made
The 30-second read
Why it matters
A sharp KOSPI decline is led by a SK Hynix operating-profit miss versus forecasts, pulling down the broader AI-chip complex across Korea and spilling into Japan and other chip-related names.
Market read
Traders should treat this as an AI-chip complex expectation reset, with SK Hynix’s forecast miss acting as the immediate catalyst and oil rebound adding macro volatility.
What to watch
The article cites progress in China toward cheaper advanced AI models, which could shift capex mix and timing; also, oil’s rebound may be a secondary driver of risk appetite rather than the core catalyst for semis.
Background
The article frames the move as renewed selling in AI-related stocks, with investors reacting to developments including China’s progress toward cheaper advanced AI models.
Ticker impact
SK Hynix shares plunged 12.8% after its quarterly operating profit missed analysts’ forecasts despite rising to a record 60.5T won.
Further downside pressure possible if investors treat the miss as demand or margin caution for AI memory.
The article cites a specific operating-profit miss and a large same-day selloff, linking the catalyst directly to the stock move.
Samsung Electronics fell 7.7% as the Kospi rout was led by selling in AI-related chipmakers.
Likely underperforms while AI-chip complex remains in sell mode; stock direction depends on whether the market extends the read-across from SK Hynix.
The article attributes the move to sector-wide selling tied to AI investment doubts, not a Samsung-specific disclosure.
Micron Technology shares sank 8.9% after having more than tripled for the year, as expectations for stellar chip earnings weigh on the group.
Near-term volatility likely elevated; downside could persist if the market continues to de-rate AI-memory expectations.
The text provides a same-day price move but no new Micron-specific earnings detail beyond the broader expectation pressure.
Advanced Micro Devices dropped 8.1% as investors sell chipmakers amid doubts about massive AI investment and weaker-than-expected profit signals.
Potential for continued weakness while AI-related chip sentiment remains pressured by read-across from earnings misses.
The article links the selloff to AI investment doubts and chipmaker weakness, but does not cite an AMD-specific new catalyst.
Applied Materials fell 7.8% alongside other chip-related stocks as the market reacts to AI investment doubts and chip earnings expectations.
Likely remains correlated with the semiconductor complex until a new company-specific catalyst emerges.
The article cites the price move and sector context, without a distinct AMAT-specific disclosure.
Market effects
Semiconductor and AI-adjacent equipment and memory names are being de-risked on earnings-expectations and AI capex doubt read-through.
KOSPI is breaking down sharply, while Tokyo and Taiwan are also down, indicating broad regional de-risking in tech/semis.
Oil rebound on Middle East missile activity can tighten financial conditions and add volatility to global risk assets, reinforcing the selloff in cyclical tech.
Counterpoint
The selloff may be an expectation reset rather than a fundamental demand collapse, since SK Hynix operating profit still rose sixfold to a record level.
