Samsung Electronics and SK Hynix surged to new record highs as expectations for an AI-driven investment cycle and foreign inflows reinforced a semiconductor-led rally.
According to the Korea Exchange, Samsung Electronics was trading at 258,000 won as of 9:07 a.m., up 25,500 won, or 10.97%, from the previous session. SK Hynix rose 135,000 won, or 9.33%, to 1,582,000 won. It climbed as much as 10.64% intraday, briefly topping 1.6 million won.
SK Square, SK Hynix’s holding company, jumped 15.94% to 1,149,000 won. Samsung Electronics’ preferred shares also advanced, up 9.08% to 185,000 won.
Analysts cited optimism about the chip cycle and global market momentum. Strength in U.S. technology shares over the Children’s Day holiday was seen as feeding into sentiment in South Korea. Expectations that expanding AI investment will lift memory demand have also kept talk of a semiconductor “supercycle” alive.
On May 5 (local time), U.S. stocks rose, with the S&P 500 and the Nasdaq both closing at record highs, according to the report. Falling international oil prices also added to a supportive backdrop.
The tech-heavy Nasdaq gained 258.32 points, or 1.03%, to finish at 25,326.126. Chip-related shares broadly advanced after reports said Apple began talks with Intel and Samsung Electronics to diversify its chip production.
