In early Asian trading, the Kospi rose 13.1% to 6,330.59. Shares of South Korean technology giant Samsung Electronics surged 19.3%, while memory chipmaker SK Hynix soared 22.6%. The Kospi index had plummeted more than 16% on Tuesday and Wednesday on a sell-off of technology stocks in part over worries about an AI bubble and rising intensive competition from chipmaking rivals in China. Tokyo's Nikkei 225 also climbed 4.9% in early Friday trading. Multinational investment holding company and OpenAI-investor SoftBank Group jumped 15.1%, while chip equipment maker Tokyo Electron rose 9.2%. The Associated Press
