Driven by OpenAI's release of the new ChatGPT model Astra last week, chip stocks continued to rise, with the biggest increase of 3.5% in Korea's benchmark stock index, the Korea Composite Index. SK Hynix and Samsung Electronics contributed the most to the index, with both stocks rising by at least 4%. Kim Namho, fund manager at Timefolio Investment Management in Seoul, said that the core driver for the rise in Korean chip companies came from the market's optimistic expectations for OpenAI's new model, which also boosted US chip stocks. Foreign and local funds bought net components of the Korea Composite Index during the early trading session, while retail investors sold them. The biggest increase in Korea's KOSDAQ index, which is dominated by the small and medium capitals, was 1.5%.
