Samsung Electronics and SK Hynix are experiencing a strong early rise, buoyed by a surge in semiconductor stocks on the U.S. stock market.

As of 9:43 a.m. on June 12, Samsung Electronics shares rose by 39,500 won (13.21%) to 338,500 won, while SK Hynix shares increased by 18,900 won (9.00%) to 2,290,000 won.

Both stocks maintained their upward momentum shortly after the market opened, with Samsung Electronics reaching 339,000 won and SK Hynix hitting 2,304,000 won at one point during the trading session. The all-time highs for both stocks were recorded on June 2, at 370,000 won and 2,407,000 won, respectively.

The rise in domestic semiconductor stocks is attributed to increased investor sentiment following a broad rally on the New York Stock Exchange, driven by optimism over peace negotiations between the U.S. and Iran.

On June 11 (local time), the Dow Jones Industrial Average rose by 1.86%, the S&P 500 climbed 1.75%, and the Nasdaq Composite increased by 2.54%. The Philadelphia Semiconductor Index surged by 7.91%, marking its largest gain in a year.

Among individual stocks, Micron Technology rose by 11.66%, Broadcom increased by 3.62%, NVIDIA gained 2.22%, and Intel saw a rise of 9.3%, reflecting a strong buying trend across the semiconductor sector.

Market analysts suggest that President Donald Trump’s comments regarding an imminent agreement with Iran have alleviated geopolitical risks in the Middle East, thereby encouraging a preference for riskier assets.

Kim Seok-hwan, a researcher at Mirae Asset Securities, noted, "President Trump's cancellation of airstrikes on Iran and remarks about progress in negotiations have heightened expectations for an end to the conflict, leading to an expansion in the gains of major U.S. stock indices. The easing of concerns over rising oil prices due to the war has also positively impacted investor sentiment."

Han Ji-young, a researcher at Kiwoom Securities, stated, "The U.S. Producer Price Index (PPI) for May has alleviated market concerns, and progress in U.S.-Iran negotiations has increased the likelihood of a peak in energy inflation, resulting in a strong performance among semiconductor stocks like Micron and NVIDIA."
