The South Korean stock market plunged on Thursday, much affected by global uncertainties that occurred during the Lunar New Year holiday.

Investor sentiment froze on Thursday, when the indices reopened after last Friday, as North Korea fired a sixth long-distance ballistic missile on Sunday and the South Korean government subsequently decided to halt operations at the inter-Korean factory park.

Stock price drops in major economies, including Japan, also contributed to the fall. 

The benchmark Korea Composite Stock Price Index(KOSPI) plummeted 56-point-25 points, or two-point-93 percent, to close at one-thousand-861-point-54. Foreign investors alone offloaded 173-point-eight billion won, or one-hundred-44-point-five million U.S. dollars.

The tech-heavy KOSDAQ also flopped 33-point-62 points, or four-point-93 percent to finish at 647-point-69.

On the foreign exchange market, the local currency weakened five-point-one won against the U.S. dollar to finish at one-thousand-202-point-five won.
