Seoul Stocks Rise for Fourth Consecutive Session on Chip Gains

On September 23, 2026, South Korean stocks continued their upward trend, marking the fourth consecutive session of gains. The surge was largely attributed to the semiconductor sector, reflecting a growing investor confidence in technology stocks.

The benchmark Korea Composite Stock Price Index (KOSPI) rose by 63.01 points, or 1.21%, closing at 7,080.92. The market opened nearly 2% higher but saw some profit-taking from foreign and individual investors, which capped further gains.

This positive momentum in the stock market follows a strong performance in the U.S., particularly in technology shares, with the Nasdaq Composite reaching record highs. Investor sentiment has been bolstered by optimism surrounding artificial intelligence stocks and easing geopolitical tensions, particularly between the U.S. and Iran.

Despite the positive trends, the market experienced a mixed performance among major players. Samsung Electronics saw a rise of 3.25%, while SK Hynix increased by 1.2%. The Korean won also gained against the U.S. dollar, indicating a favorable economic outlook.

As the Chuseok holiday approaches, analysts suggest that investors may adopt a cautious stance, waiting for key developments in the market.
