An electronic board at a Hana Bank dealing room in Jung-gu, Seoul, displays the KOSPI index on April 27. The KOSPI closed at 6,615.03, up 139.40 points (2.15%), while the KOSDAQ rose 22.34 points (1.86%) to 1,226.18.

South Korea’s stock market continued its rally despite ongoing geopolitical tensions in the Middle East, with the benchmark KOSPI surpassing the 6,600 mark for the first time and total market capitalization exceeding 6 trillion won.

According to the Korea Exchange, the KOSPI closed at 6,615.03 on April 27, up 2.15% (139.40 points) from the previous session. The index briefly rose to 6,603.01 around 10:05 a.m., marking its first-ever break above the 6,600 level. The tech-heavy KOSDAQ also gained 1.86% to finish at 1,226.18.

The rally was driven by strong gains in semiconductor and power equipment stocks, supported by net buying from both institutional and foreign investors. Large-cap semiconductor stocks led the upward momentum, with Samsung Electronics rising 2.28% and SK hynix jumping 5.73%.

With the market surge, the combined market capitalization of the KOSPI and KOSDAQ exceeded 6 trillion won for the first time, reaching approximately 6,101 trillion won at closing. This compares with about 5,972 trillion won recorded in the previous session on April 24.

Meanwhile, the total market value of listed affiliates under HD Hyundai Group also surpassed 200 trillion won for the first time, about 24 years after the group split from Hyundai Group in 2002. Among its affiliates, HD Hyundai Heavy Industries accounted for the largest share at 70.6 trillion won, followed by HD Hyundai Electric and HD Korea Shipbuilding & Offshore Engineering.

Analysts said the rally came despite lingering uncertainty in the Middle East. “Although negotiations in the region remain ongoing, strong performance in semiconductor and power equipment stocks pushed the KOSPI above 6,600 during the session,” said Kang Jinhyuk, a researcher at Shinhan Investment & Securities.

Power equipment stocks also surged, with Hyosung Heavy Industries and LS ELECTRIC rising 10.95% and 12.80%, respectively.

The Korean won strengthened slightly against the U.S. dollar, with the exchange rate closing at 1,472.5 won per dollar, down 12 won from the previous session.
