The benchmark Korea Composite Stock Price Index(KOSPI) surpassed the three-thousand-500 mark just two weeks after hitting an all-time high of three-thousand-400.

As of 2 p.m. Thursday, the KOSPI had risen two-point-74 percent from Wednesday's closing to three-thousand-550-point-40.

The main bourse opened the day's trading at three-thousand-535-point-48, up two-point-02 percent from the previous day's closing.

Foreign investors led the gains, purchasing a net one-point-37 trillion won, or around 980 million U.S. dollars, worth of shares. 

The tech-heavy KOSDAQ climbed zero-point-78 percent from Wednesday to 851-point-92.

The skyrocketing index comes after the dollar weakened against the Korean won amid fears that sluggish economic indicators could accelerate the U.S. Federal Reserve's rate-cut cycle.
