South Korea’s stock market boom, driven by a global frenzy over artificial intelligence (AI) chips, is delivering hefty gains for Chinese investors piling into cross-border semiconductor funds.

The benchmark Kospi index has surged more than 80% this year to record highs, powered largely by chip giants Samsung Electronics and SK Hynix, which together account for more than 40% of the index. The rally has pushed South Korea past the U.K. and Canada to become the world’s seventh-largest equity market.
