Shares of South Korean semiconductor giant SK Hynix jumped 15% on Wednesday after Samsung Electronics raised its first-quarter profit outlook. Samsung flagged an over-eightfold increase in profits, driven by soaring demand for AI infrastructure.

The surge in chip prices and supply constraints have boosted investor confidence in SK Hynix, which also benefits from the broader semiconductor boom. Its stock rose to 1,050,000 won per share.

The broader market also advanced by 7%, outpacing Samsung’s 8.7% gain.
