SEOUL, Sept. 7 (Yonhap) — South Korean shares rebounded Monday, led by an advance in top cap Samsung Electronics and some bio stocks. The Korean won rose against the U.S. dollar.

The benchmark Korea Composite Stock Price Index (KOSPI) rose 15.97 points, or 0.67 percent, to close at 2,384.22.

Trading volume was moderate at about 1.2 billion shares worth some 16.9 trillion won (US$14.2 billion), with gainers outnumbering losers 641 to 224.

Foreigners sold a net 247 billion won, while retail investors purchased a net 543 billion won. Institutions offloaded a net 297 billion won.

The KOSPI rebounded from a 1.15 percent plunge the previous session, despite growing stock price valuation concerns.

“The tech losses on Wall Street affected Asia stocks in general but had limited influence over South Korean stocks, thanks to strong chip advances,” Shinhan Financial Investment analyst Choi Yoo-joon said.

 A slowdown in daily COVID-19 cases also helped boost investor sentiment.

The country added 119 more COVID-19 cases as of Monday, marking a sharp fall from 167 additional cases reported Sunday and the fewest in nearly a month.

On Friday, South Korean authorities decided to extend the enhanced social distancing scheme by a week to Sept. 13, to curb the new infection rate.

In Seoul, most large caps closed lower.
