Hynix jumps nearly 13%, driving KOSPI to record intraday high
Nikkei Asia reports that SK Hynix shares surged nearly 13% on AI demand and memory chip supercycle expectations. The move pushed the KOSPI to a record high. Investors expect the semiconductor rally to extend into coming quarters.

Nikkei Asia reports that SK Hynix shares surged close to 13% in the session, driving South Korea's benchmark KOSPI to a record intraday high. The move followed renewed reports that high-bandwidth memory demand for global AI data centres remains strong. Investors are pricing in record profit levels at memory chip makers over the coming quarters.
Samsung Electronics and Micron Technology also traded at a premium on AI-driven demand. Analysts expect HBM capacity to grow by nearly 50% year over year. Tight memory chip supply leaves further room for price increases.
The KOSPI's record-setting close has accelerated the rotation of global investment funds into South Korean assets. The won strengthened against the dollar on a weekly basis. Analysts say the outcome of the Trump-Xi summit and Beijing's rare-earth policy in the coming days will set the direction for the Asian tech rally.
