South Korean stocks are on the cusp of surpassing last year’s world-beating 76% gain, even though 2026 is less than five months old.

The benchmark Kospi surged 6.5% Wednesday to bring this year’s advance to 75%, its eighth daily gain of more than 5% this year, compared with just one such rally in 2025. Overseas investors bought more than $2 billion of Kospi shares for the day, just a fraction below the record seen in October.
