The KOSPI index recovered from an early plunge driven by U.S. rate hike fears, closing at 6,820.02 thanks to strong buying from corporate entities.
What Happened
Market Dynamics: The KOSPI index experienced a volatile session, initially plummeting to the 6,500 level due to concerns over U.S. interest rate hikes. However, the market managed to reverse its losses throughout the day, eventually closing up 0.46% at 6,820.02.
Supply and Demand: Despite significant net selling by foreign and institutional investors, corporate entities stepped in as major buyers, injecting over 1.5 trillion won into the market. This buying spree, largely linked to share buybacks by major semiconductor firms, provided a crucial floor for the index.
Key Movers: Semiconductor giants Samsung Electronics and SK Hynix turned positive during the session, leading the market recovery. Conversely, Korea Zinc shares tumbled amid an ongoing management dispute, while other industrial stocks like Hanwha Aerospace faced downward pressure.
KOSDAQ Performance: The KOSDAQ index failed to follow the main board's recovery, ending the day down 0.49% at 834.29. While battery-related stocks saw gains, the biotech sector, including companies like Alteogen, experienced notable declines.
