KOSPI Re-Collapses Below 7,000 Level as Both Markets Trigger Sidecar Mechanism

South Korea's benchmark indices plunged over 5% this week as the KOSPI and KOSDAQ triggered sidecar mechanisms amid geopolitical tensions and rising oil prices. The KOSPI closed at 6,690.62, down 5.72% from the previous day's close, while the KOSDAQ dropped 5.32% to 748.22. Foreign investors and institutions were net sellers, while individuals drove buying activity. Major stocks like Samsung Electronics and SK Hynix fell sharply, though Samsung Biologics rose. The USD/KRW exchange rate declined to 1,466.80, reflecting market volatility.
