South Korea’s AI stocks struggle for buyers as memory-chip doubts grow

Bloomberg reports in The Business Times that South Korea’s Kospi has lost 22% since the first half of 2026. Samsung Electronics and SK Hynix account for over half the index’s weighting, while investors question how long the memory-chip boom will last. Some favor Taiwan for its broader AI supply-chain links, though the Kospi remains among 2026’s best performers overall.
