South Korea’s equity benchmark is building on its strongest monthly rally in over two decades, underscoring the market’s rising prominence in the global AI race following Nvidia Corp.’s recent deals with local firms.

After surging 20% in October, its best monthly gain since 2001, the Kospi Index kicked off November with a brisk start, climbing as much as 2.7% to a record high. Up 76% year-to-date, the benchmark remains the world’s top-performing major stock index.
