Data compiled by Woofun AI shows the South Korean KOSPI index erased an early 4% gain, reversing course intra-day to finish down over 1%. This sharp reversal was primarily driven by volatility in the technology sector, where Samsung Electronics narrowed its advance to 3% and SK Hynix retreated by 3%.

Concurrently, cross-border market sentiment weakened, with the Hong Kong-listed Southbound Double Bull Hynix dropping over 8.6% amid the broader regional sell-off.
