On October 13, SK hynix fell 5.38% in Pre-Market Trading, with shares at $153.87 and turnover of $30.4814 million.

The move followed a sharp selloff in South Korean and Japanese technology shares, as the AI trade cooled and memory-chip competition concerns intensified, pressuring SK hynix and other semiconductor names.

Earlier on October 13, SK hynix shares in Korea extended losses to as much as 10.3%, after already falling more than 8% in the morning. The broader Korean market dropped more than 5% and triggered the KOSPI Sidecar mechanism, temporarily halting program sell orders. Samsung Electronics also fell sharply, while SoftBank, Tokyo Electron and Advantest declined in Japan, indicating broad weakness across the regional AI and semiconductor chain.

Additional pressure came from reports that foreign ownership in SK hynix had stayed below 50% for multiple sessions and that ASML had notified Samsung and SK hynix of a 10% parts price increase, reinforcing concerns over sentiment, costs and industry competition.
