Samsung Electronics and SK Hynix Shares Plunge Amid Weak U.S. Semiconductor Market

Samsung Electronics and SK Hynix are experiencing significant declines in early trading due to the weak performance of U.S. semiconductor stocks overnight.


As of 9:59 a.m. on the Korea Exchange, Samsung Electronics shares were trading at 250,000 won, down 18,500 won (6.89%) from the previous trading day. SK Hynix also saw a drop of 14,000 won (8.42%), bringing its stock price to 1,522,000 won.


The downturn in both stocks is attributed to a broad decline in semiconductor-related shares on the New York Stock Exchange.


Last night, the Philadelphia Semiconductor Index fell by 4.98%. Micron Technology, a memory chip maker, dropped 7.02%, while SanDisk fell by 9.01%. SK Hynix's American Depositary Receipts (ADRs) plummeted by 9.20%.


The widening losses in semiconductor stocks are analyzed as a response to rising geopolitical tensions in the Middle East, which have heightened concerns about inflation and interest rate increases.


With international oil prices on the rise and U.S. long-term Treasury yields remaining high, investor sentiment towards technology stocks has weakened. A message from U.S. President Donald Trump indicating that negotiations with Iran are not currently underway has also fueled risk-averse sentiment.


Seo Jeong-hoon, a researcher at Samsung Securities, stated, "The index has shown weakness due to rising international oil prices and long-term Treasury yields stemming from the situation in the Middle East. In particular, the increased volatility of semiconductor-related stocks is putting pressure on the domestic market."


Jo Jae-woon, a researcher at Daishin Securities, noted, "Concerns about inflation have intensified due to the deepening geopolitical risks in the Middle East, leading to a decline in investor sentiment focused on technology stocks. The upcoming FOMC minutes and the Jackson Hole meeting will be key variables influencing short-term volatility regarding the Federal Reserve's inflation assessment."
