South Korean shares closed lower Friday, snapping a four-day winning streak, as economic uncertainties loom large amid the new coronavirus pandemic. The Korean won rose against the US dollar.

The benchmark Korea Composite Stock Price Index (KOSPI) lost 17.64 points, or 0.78 percent, to close at 2,249.37. Trading volume was high at about 679 million shares worth some 12.7 trillion won ($10.7 billion), with losers outnumbering gainers 572 to 276.

Foreigners sold a net 86 billion won, ending a five-session buying streak. Institutions offloaded a net 394 billion won, while retail investors purchased a net 473 billion won.

The market remained bearish, extending losses toward the session's close.

Investors attempted to lock in gains after the US economy contracted by the most in 73 years in the second quarter.

"The steep fall in the US quarterly growth, consumption and facility investment generates negative pressure on export-driven markets like South Korea," said Seo Sang-young, an analyst at Kiwoom Securities Co.

In contrast, South Korea's industrial output, retail sales and facility investment showed on-month growth in June. It is the first time in six months that all three indices increased.

Most large caps closed in negative terrain.
