The Korea Composite Stock Price Index (KOSPI) broke an all-time high the day before President Lee Jae Myung's 100th day in office.

The Korea Exchange on Sept. 10 said the nation's benchmark stock index closed that day at 3,314.53, up 54.48 points (1.67%) from the previous day and breaking the previous mark of 3,305.21 set on July 6, 2021.

The main driver of the rally was foreign buying, which reached a net KRW 1.38 trillion. Analysts attributed this to improved investor sentiment thanks to government stimulus to boost the stock market and revisions to the Commercial Act.

KOSPI has also led the Group of 20 advanced economies in growth with 38% this year and 4% this month.
