Memory-chip makers led a KOSPI rebound, with the index rising as much as 8%
after sliding about 15% from its record high over three days. Samsung
Electronics gained up to 9.1% and SK Hynix more than 14%. A prior AI-driven
rally had pushed KOSPI year-to-date gains above 100% but collapsed on Monday,
triggering circuit breakers and briefly halting trading. Leveraged ETFs
magnified the move and intensified the sell-off. Samsung Securities analyst Lee
Jongwook said volatility reflects market-structure changes rather than a
cyclical directional shift, and advised maintaining positions or adding
opportunistically after the liquidation.
