South Korean shares snapped their two-day gains Tuesday after hitting a nearly three-year high the previous session, as valuation pressure offset optimism over Moderna's experimental COVID-19 vaccine. The Korean won rose against the US dollar.
After choppy trading, the benchmark Korea Composite Stock Price Index (KOSPI) fell 3.88 points, or 0.15 percent, to close at 2,539.15.
Trading volume was high at about 1.2 billion shares worth around 17.5 trillion won ($15.8 billion), with losers outnumbering gainers 524 to 318.
Foreigners purchased a net 359 billion won, extending their buying streak to a ninth session. Retail investors bought a net 152 billion won, while institutions offloaded a net 513 billion won.
"Yesterday's rally seems to have increased investors' desire for profit-taking," Kiwoom Securities analyst Seo Sang-young said.
Valuation pressure and the unrelenting coronavirus toll increased investor caution, while strong test results from Moderna's experimental COVID-19 vaccine pegged the KOSPI's further loss.
