SEOUL, Aug. 13 (Yonhap) -- South Korean shares closed a tad higher Thursday, extending gains to a ninth session on institutional and individual buying. The Korean won rose against the U.S. dollar.
The benchmark Korea Composite Stock Price Index (KOSPI) rose 5.18 points, or 0.21 percent, to close at 2,437.53.
Trading volume was high at about 892 million shares worth some 18 trillion won (US$15.2 billion), with gainers outnumbering losers 481 to 359.
The index came to a strong start but erased most of the gains on strong foreign sell-off. Foreigners dumped a net 352 billion won on profit-taking, the largest amount since July 7.
Retail investors purchased a net 157 billion won, and institutions bought a net 186 billion won.
Analysts said the KOSPI continued to rally in the past nine straight sessions as retail buying offset foreign selling
"The money move generated by individual investors has become a significant force in the financial markets," Hana Financial Investment analyst Kim Yong-koo said.
Rising hopes for new coronavirus vaccines also boosted investor sentiment.
Clinical trials on three locally developed vaccine candidate materials for COVID-19 are expected to start within this year, South Korean health authorities said.
