The KOSPI opened with a surge of over 6%, driven by a rally in U.S. semiconductor stocks and expectations of reduced geopolitical risks in the Middle East. Following a strong performance in the New York stock market, buying activity has concentrated on major semiconductor firms such as Samsung Electronics and SK Hynix.
As of 9:07 a.m. KST, the KOSPI was up 518.36 points (6.68%) at 8,282.31. The index started at 8,263.85, an increase of 499.90 points (6.44%) from the previous session, and continued to climb.
On June 11, the Dow Jones Industrial Average closed up 929.97 points (1.86%) at 50,848.75. The S&P 500 rose by 127.31 points (1.75%) to finish at 7,394.30, while the tech-heavy Nasdaq gained 640.16 points (2.54%) to close at 25,809.66.
U.S. markets were buoyed by a May Producer Price Index (PPI) that eased market concerns, along with President Donald Trump’s announcement of a withdrawal from plans to strike Iran and the potential for progress in negotiations. This optimism was further fueled by strong performances from semiconductor stocks, including Micron (up 11.7%), Intel (up 9.3%), and Nvidia (up 2.2%).
At this time, institutional investors are net buyers in the securities market, purchasing 318.3 billion won. In contrast, foreign and individual investors are net sellers, offloading 263.9 billion won and 10.01 billion won, respectively.
Among the top market capitalization stocks, Samsung Electronics (up 9.53%), SK Hynix (up 9.09%), SK Square (up 10.18%), Samsung Electro-Mechanics (up 9.75%), Hyundai Motor (up 5.53%), LG Energy Solution (up 3.77%), Samsung Life Insurance (up 8.63%), and Samsung C&T (up 10.73%) are all showing strong gains.
Meanwhile, the KOSDAQ index has risen by 31.85 points (3.19%) to 1,028.78. It started at 1,027.05, up 30.12 points (3.02%), and has maintained its upward trend.
In the KOSDAQ market, individual investors are net buyers, acquiring 265 billion won, while foreign and institutional investors are net sellers, selling 244.2 billion won and 26.6 billion won, respectively.
Most of the top KOSDAQ stocks, including Alteogen (up 0.43%), EcoPro BM (up 4.08%), EcoPro (up 4.96%), JUSUNG Engineering (up 9.78%), Rainbow Robotics (up 3.14%), Kolon TissueGene (up 1.84%), Wonik IPS (up 12.48%), and Rino Technology (up 0.80%), are also experiencing increases.
Han Ji-young, a researcher at Kiwoom Securities, stated, "Expectations are rising for a memorandum of understanding between the U.S. and Iran, along with easing inflation concerns in the U.S. and strong semiconductor stocks, which are improving investor sentiment. The KOSPI 200 futures surge is likely to lead to a strong domestic market opening, followed by a rotation among sectors."
He added, "Recent adjustments have alleviated excessive concentration burdens, and the environment for sector rotation is improving. While strategies focusing on expanding the share of leading stocks in semiconductors and the AI value chain remain valid, it is also important to pay attention to sectors like securities, banking, and shipbuilding that have been relatively overlooked."
