South Korean stocks closed lower Tuesday, marking the sixth consecutive session drop amid rising concerns over a potential nuclear test by Pyongyang, analysts said.
The benchmark Korea Composite Stock Price Index fell 9.47 points, or 0.44 percent, to close at 2,123.85. Trade volume was moderate at 460.2 million shares worth 4 trillion won ($3.49 billion), with gainers outnumbering losers 409 to 384.
Analysts attributed the drop to the escalating concern that the North will soon press ahead with another nuclear test and a long-range missile launch.
Concerns over a potential clash with North Korea have been fueled by the Donald Trump administration's recent air strike against Syria.
"The influence of the geopolitical crisis of the Korean Peninsula may continue for the time being," said Lee Kyung-min, a researcher at Daishin Securities Co.
