KOSPI triggers sidecar mechanism amid semiconductor selloff

KOSPI SK Hynix Samsung Electronics semiconductor selloff sidecar mechanism

South Korea's KOSPI index experienced a severe downturn, dropping as much as 6% and triggering the 'sidecar' mechanism to temporarily suspend program trading. This volatility was driven by a global semiconductor selloff, rising US Treasury yields—with the 30-year yield hitting approximately 5.33%—and increased geopolitical tensions in the Middle East affecting oil prices.

Major semiconductor firms were heavily impacted, with Samsung Electronics and SK Hynix seeing significant declines. However, SK Hynix later announced a massive shareholder return plan, including the repurchase and cancellation of 40 trillion won in shares, which provided some support during subsequent trading sessions.

Market analysts noted that leveraged ETFs targeting single stocks may have amplified the volatility. While individual investors engaged in net buying to support the market, foreign and institutional investors remained net sellers during the peak of the decline.
