What it means
A record selloff in South Korean stocks driven by SK Hynix earnings disappointment has historically been associated with sharp near-term declines in global semiconductor ETFs and Korean equity funds. The AI spending narrative underpinning much of the chip sector rally is being questioned, which has historically spread pressure to US tech and Nasdaq-linked assets in the short term.
