11-Day Winning Streak: KOSPI 4800 Record High 2026 and 4,000 Trillion Won Milestone

It's an 11-day winning streak that shows no signs of slowing down. South Korea's benchmark index just shattered the 4,800-point barrier for the first time in history. Driven by a massive rally in semiconductor giants, the KOSPI has pushed the total market capitalization above the 4,000 trillion won mark, opening a new chapter for the nation's equity market.

Inside the KOSPI 4800 Record High 2026 Rally

On January 16, 2026, the KOSPI finished at a record-breaking 4,840.74, up 43.19 points (0.9%) from the previous session. The index even touched an intraday high of 4,863.82 just before the close. Since the start of the year, the index hasn't seen a single day of losses, climbing nearly 15% in just 11 sessions. This follows a stellar 2025 where the market posted an annual return of over 75%.

The rally's heavy lifters were the chipmakers. Industry leader Samsung Electronics surged 3.47% to 148,900 won, while SK hynix added 0.93%. Analysts point to external factors like TSMC's robust growth report and the U.S.-Taiwan trade agreement as key catalysts that boosted sentiment for Korean tech stocks.
