[Closing 2026-03-27] KOSPI Slips to 5,438.87 on Foreign Selling while KOSDAQ Recovers 0.43%

Market Overview

The South Korean stock market finished the week on a mixed note this Friday, March 27, 2026. The benchmark KOSPI (KRX: KOSPI) edged lower as persistent diplomatic uncertainties and foreign sell-offs weighed on large-cap sentiment. Conversely, the secondary KOSDAQ (KRX: KOSDAQ) managed a modest gain, buoyed by retail interest in growth sectors despite broader market volatility.

KOSPI Performance

The KOSPI index closed at 5,438.87, down 21.59 points or 0.40% from the previous session. After a volatile week that saw the index swinging between 5,200 and 5,600 levels, the benchmark ended near its intraday lows. The trading volume was recorded at approximately 889.78 million shares, with a turnover value of 23.04 trillion won.

KOSDAQ Performance

The tech-heavy KOSDAQ index showed more resilience, finishing at 1,141.51, up 4.87 points or 0.43%. The index benefited from a rebound in select biotech and battery material stocks, though gains were capped by cautious institutional sentiment. Trading volume stood at 1.45 billion shares with a turnover of 12.44 trillion won.

Investor Flows and Market Movers

Foreign investors continued their selling streak in the main board, recording a net sell-off of approximately 38.77 billion won. Institutional investors, however, supported the market with a net purchase of 7.78 billion won, while retail investors added 27.13 billion won to their holdings. In the KOSDAQ market, retail investors were net buyers of 1.70 billion won, while foreigners sold 2.34 billion won worth of shares.

Market Analysis and Themes

The primary driver for today’s market movement remained “Diplomatic Uncertainty,” as noted by several market analysts. While the semiconductor giants Samsung Electronics and SK hynix faced downward pressure, the secondary battery sector showed signs of recovery following a sharp correction earlier in the week. The “Sidecar” triggers seen earlier in the week have left investors cautious, leading to a consolidation phase as the market digests recent geopolitical developments.
