The KOSPI index experienced extreme volatility, swinging over 200 points during the session before ending slightly higher amid market uncertainty.
What Happened
Extreme Intraday Volatility: The KOSPI index saw a dramatic session, surging to 6,682 before plunging toward the 6,400 level, marking a swing of over 240 points. The index ultimately managed to close up 0.26% at 6,579.48, narrowly avoiding a deeper decline.
Supply and Demand Imbalance: While retail, foreign, and institutional investors were net sellers, 'other corporations' provided significant support through heavy buying. This buying activity was largely attributed to share repurchase programs by major firms like Samsung Electronics and SK Hynix.
Market Uncertainty: Speculation regarding a potential interest rate hike by the Bank of Japan fueled concerns over the unwinding of yen carry trades, contributing to market jitters. Without a clear fundamental catalyst, heavy selling from financial investment firms and pension funds exacerbated the intraday swings.
Sector Divergence: Banking stocks benefited from the interest rate environment, while semiconductor and pharmaceutical sectors faced downward pressure. The KOSDAQ index continued its four-day losing streak, reflecting persistent caution among investors.
