Sep 8, 2026 07:11 (47d ago)

KOSPI closed at 6,954.52, down 0.58%, after reaching 7,171.52 and failing to hold above 7,000 during an early semiconductor-led advance.
Reported September 8 flows differed between accounts: foreign investors bought about 658.2 billion to 661.6 billion won, institutions bought about 649.5 billion to 932 billion won, and retail investors sold about 3.0533 trillion to 3.3265 trillion won.
Foreign and institutional buying continued for a fourth session, but analysts said retail positions of about 87 trillion won above the 7,000 level, or 111.5 trillion won including financial investment accounts, could create a supply overhang.

The KOSPI closed at 6,954.52 on September 8, down 40.87 points, or 0.58%, after opening above 7,000 and reaching 7,171.52. Semiconductor shares initially advanced following OpenAI's Astra artificial-intelligence model launch, which strengthened expectations for high-bandwidth memory, high-capacity memory and networking demand. The rally reversed as retail investors sold heavily amid Saudi energy-facility attacks, continuing U.S.-Iran tensions, U.S.-Canada trade friction, higher oil prices, rising U.S. Treasury yields and concerns about ETF rebalancing and lower liquidity. Foreign and institutional investors extended reported joint net buying to four sessions, although the sources provide differing September 8 flow figures. Analysts said the market needs sustained foreign and institutional demand to absorb large retail positions accumulated above 7,000.
