South Korean chip stocks slide after overnight US selloff on AI boom concerns

South Korean semiconductor stocks, including major players like Samsung Electronics and SK Hynix, saw significant declines in morning trading, mirroring an overnight selloff in US tech giants. This downturn was largely attributed to increasing market anxieties that the unprecedented rally driven by the artificial intelligence (AI) boom may be reaching unsustainable levels.

While no specific catalyst beyond the broader market sentiment was cited, the interconnectedness of global semiconductor supply chains means that a pullback in US tech often ripples through Asian markets. South Korea is home to some of the world's largest memory chip manufacturers, which are crucial suppliers to the AI industry.

The core tension lies in whether this correction is a healthy recalibration within a long-term growth trend for AI-related hardware, or if it signals a more profound shift in investor sentiment regarding the sector's valuation. Traders are now weighing the potential for a rebound driven by continued AI demand against the risk of further declines if the 'AI bubble' narrative gains more traction.

Key watch points include the performance of bellwether US tech stocks, upcoming earnings reports from major chipmakers for any signs of demand softening, and broader macroeconomic indicators that could influence risk appetite.
