Samsung, SK Hynix Drive Korea Benchmark’s Breakthrough Past 6000

South Korea’s equity benchmark has crossed a new milestone just a month after surpassing the once-unthinkable 5,000 mark, as surging global memory demand powers the country’s biggest chipmakers.

The Kospi Index advanced 1.9% to a record 6,084 Wednesday, with Samsung Electronics Co. and SK Hynix Inc. each gaining more than 1%. With the benchmark now up 44% for 2026, Korea’s stock market capitalization has also moved past France’s, following last month’s overtaking of Germany’s.
