[Financial News] The Korea Composite Stock Price Index (KOSPI) plunged more than 12% at one point during intraday trading on the 4th, marking the largest drop on record. Geopolitical risks in the Middle East spread across the market, sharply undermining investor sentiment.
According to the Korea Exchange (KRX), as of 1:30 p.m., the KOSPI was trading at 5,258.20, down 533.71 points, or 9.21%, from the previous session.
During the session, the index at one point tumbled to 5,059.45, a drop of 732.46 points, or 12.65%, from the previous close.
Both the point decline and the percentage loss were the largest ever recorded since the Korea Exchange began compiling such data.
On the KOSPI Market that day, only 19 listed stocks rose, while 905 stocks declined.
At the same time, the Korea Securities Dealers Automated Quotations (KOSDAQ) index was trading at 1,018.95, down 118.75 points, or 10.44%, from the previous session.
Earlier in the day, the index had plunged to as low as 976.54, a fall of 161.16 points, or 14.17%, during intraday trading.
