Despite U.S. President Donald Trump's remarks that he would roll back tariffs on Korean products to levels before a trade deal, the KOSPI on Jan. 27 surged by nearly 3 percent to regain the 5,000 level.
The KOSPI ended the session at 5,084.85, up 135.26 points, or 2.73 percent, from the previous close.
It was the first time the KOSPI finished above 5,000 on a closing basis. The index also set a record closing high and simultaneously broke the intraday record set a day earlier at 5,023.76.
The index opened at 4,932.89, down 16.70 points, or 0.34 percent. It slid as far as 4,890.72 before quickly paring losses and extending gains.
The KOSDAQ also ended higher, closing at 1,082.59, up 18.18 points, or 1.71 percent, from the previous session.
After topping 1,000 for the first time in about 4 years the previous day and setting a post-revision record since the 2004 overhaul, the KOSDAQ opened at 1,054.19, down 10.22 points, or 0.96 percent, but soon rebounded.
