South Korean stocks ended their three-day losing streak Tuesday, following the US Federal Reserve's comments that helped ease concerns of early post-pandemic inflation. The Korean won rose against the US dollar.

The benchmark Korea Composite Stock Price Index (Kospi) rose 27.02 points, or 0.86 percent, to close at 3,171.32 points.

Trading volume was moderate at about 603 billion shares worth some 11.5 trillion won ($10.2 billion), with gainers outnumbering losers 618 to 224.

Foreigners bought a net 68 billion won, while retail investors sold a net 960 billion won. Institutions purchased a net 884 billion won.

Investor sentiment ran high throughout the trading, tracking 1.41 percent overnight gains on the tech-laden Nasdaq that followed the Fed's key officials comments that the recent price hikes and supply shortages may be temporary.

The Dow Industrial Average and the S&P 500 rebounded 0.54 percent and 0.99 percent, respectively.

"Investor appetite for bargain hunting seems to have increased over tech stocks, leading to the index's hike," Mirae Asset Securities analyst Seo Sang-young said.
