KOSPI drops 1% after earlier 1.8% gain; SK Hynix, Samsung fall

The reversal from a 1.8% gain to a 1% loss underscores how fragile tech-led rallies are in the current risk environment. The drag from heavyweight memory and semiconductor names like SK Hynix and Samsung suggests sector-specific pressure, not just index-level noise. This matters for regional tech sentiment, as Korea's market often acts as a bellwether for chip demand and export-driven economies. The key question is whether this is a short-term profit-taking pullback after an early surge, or the start of a broader correction if tech weakness persists into the next sessions.
