The benchmark Korea Composite Stock Price Index plunged 159-point-06 points, or three-point-81 percent, on Friday to close at four-thousand-eleven-point-57.

This marks the lowest closing since November 7, when the main bourse closed at three-thousand-953-point-76.

Analysts attributed the tumble to an overnight tech dump on Wall Street, during which overvaluation worries weighed on Nvidia and other significant U.S. tech shares, dragging tech-heavy Asian markets down.
 
The tech-heavy KOSDAQ fell 20-point-47 points, or two-point-23 percent, to close at 897-point-90.
 
The South Korean won strengthened against the U.S. dollar by ten-point-seven won to trade at one-thousand-457 won as of 3:30 p.m.
