On June 16, shares of South Korea's leading semiconductor companies, SK Hynix and Samsung Electronics, rose by over 2% in early trading, buoyed by a surge in U.S. semiconductor stocks the previous day.

According to NextTrade, as of 8:35 a.m., SK Hynix's stock increased by 67,000 won (2.93%) to 2,355,000 won. Samsung Electronics saw a similar rise, gaining 9,500 won (2.52%) to trade at 346,500 won.

In the U.S. stock market, semiconductor stocks rebounded as investors engaged in bargain hunting following recent declines. On June 15, the Dow Jones Industrial Average closed up 468.77 points (0.92%) at 51,671.03. The S&P 500 rose by 122.83 points (1.65%) to finish at 7,554.29, while the Nasdaq Composite surged 795.10 points (3.07%) to close at 26,683.94.

Notable individual stock performances included Micron, which rose 10.84%, Western Digital at 16.1%, SanDisk at 6.45%, Seagate at 9.43%, and Nvidia at 3.54%.

Han Ji-young, a researcher at Kiwoom Securities, noted, "Today, we expect a strong start due to the easing of tensions between the U.S. and Iran, which has led to declines in oil prices and interest rates, along with the rally in U.S. semiconductor stocks."

She added, "The positive news from the U.S. has already been partially reflected in the domestic market, and we may see a rotation into other sectors after the initial strength in semiconductor stocks."
