South Korea’s KOSPI index surged to a record high of 6,355.39 points, climbing as much as 2.2% on Tuesday. The rally was primarily fueled by significant gains in technology stocks, particularly chipmakers benefiting from the artificial intelligence boom.
SK Hynix Inc was a key driver, with its stock rising over 4% to a new peak. This followed the company's announcement that it had begun mass production of advanced memory modules for NVIDIA's AI processors. Fellow chip giant Samsung Electronics also saw its stock increase by 2%, approaching its own record high and contributing to the index's strong performance.
Beyond the tech sector, broader Asian markets experienced a boost in risk appetite. This positive sentiment was partly influenced by optimism surrounding potential peace talks between the U.S. and Iran, which improved investor confidence across the region and supported the KOSPI's upward momentum.
The performance of the KOSPI highlights the critical role of the semiconductor industry, especially its connection to AI advancements. Investors will continue to monitor developments from major chipmakers like SK Hynix and Samsung, as their performance is a key indicator for the market's direction.
