Korean shares slide after tech rally fizzles on weak Broadcom guidance
Korean tech shares fell Friday as AI-related losses spread from Wall Street after Broadcom reported Q2 revenue of $22.19 billion and issued weak guidance, with CEO Hock Tan not raising the full-year AI chip sales target of $100 billion. Samsung and SK Hynix dropped up to 8%, while Arm and Micron also fell.

Weak guidance is the primary catalyst driving broader semis/AI risk-off and likely pressures AI-adjacent supply-chain names.
Broadcom reported Q2 revenue of $22.19B and issued weak guidance, with CEO Hock Tan not raising full-year $100B AI chip sales target.
Near-term downside bias for semis/AI hardware complex until guidance read-through stabilizes.
Background
The article frames a prior AI-led rally to record highs, then highlights Broadcom’s Q2 results and guidance as the trigger for a tech/AI pullback across Asia and the US.
Why it matters
Broadcom’s weak guidance is presented as the key fundamental datapoint; the rest of the market reaction is described as spillover into other AI/semiconductor names and Korean tech heavyweights.
Market relevance
Treat this as a semis/AI guidance read-through event: Broadcom’s guidance resets near-term sentiment and can drag correlated AI hardware names.
Market effects
Weak AI-chip guidance read-through pressures the broader semiconductor complex (logic, memory, and AI infrastructure supply chain).
Korean tech heavyweights (Samsung, SK Hynix) fall as investors become cautious after record valuations.
Nasdaq tech weakness and AI-driven capex expectations are being repriced globally after Broadcom’s guidance miss.
Alternative perspectives
The selloff may be an overreaction if Broadcom’s guidance conservatism reflects timing (mix/shipments) rather than demand destruction.
Investors may be focusing on the full-year AI chip sales target, but near-term order cadence and customer inventory cycles could stabilize the complex quickly.
