Korean shares slide after tech rally fizzles on weak Broadcom guidance
Korean tech stocks fell after Broadcom’s weak guidance cooled an AI-led rally. Samsung and SK Hynix dropped up to 8%, pulling the index down about 4%. Broadcom reported Q2 revenue of $22.19 billion, and CEO Hock Tan kept the full-year AI chip sales target at $100 billion. Arm and Micron also slid, with the Nasdaq tech segment down.

Guidance disappointment is the primary catalyst driving broader chip weakness and AI-semantics risk-off.
Broadcom reported Q2 revenue of $22.19B and issued weak guidance, with CEO Hock Tan not raising the full-year $100B AI chip sales target.
Near-term downside pressure likely extends to AI/semis complex as investors reprice AI chip demand expectations.
Background
The article frames a prior AI-driven rally to record highs, then attributes the reversal to Broadcom’s Q2 earnings and guidance disappointment.
Why it matters
Broadcom’s weak guidance is presented as the trigger for a broad selloff across AI/semis, which then pressured Korean tech and other AI-exposed names via read-across.
Market relevance
Treat Broadcom’s guidance as a near-term sentiment reset for the AI semiconductor complex, with spillover risk to AI infrastructure beneficiaries.
Market effects
Broadcom’s guidance reset is a read-through for AI chip demand and capex expectations, pressuring the broader semiconductor/AI complex.
Korean tech heavyweights (Samsung, SK Hynix) fell as investors turned cautious after the AI-led rally.
US tech/semis weakness spilled into Asia, with Nasdaq tech down and Japan/Asia AI winners cooling.
Alternative perspectives
The selloff may be more about expectations (guidance vs. lofty forecasts) than a fundamental demand break in AI infrastructure.
Investors may be over-weighting one company’s guidance; subsequent AI capex signals (hyperscaler spend, memory pricing, other chip prints) could quickly stabilize sentiment.
