SEOUL, Feb. 22 (Yonhap) — South Korean stocks retreated below the 3,100-point mark Monday, erasing morning gains despite strong export data. The Korean won fell against the U.S. dollar.

The benchmark Korea Composite Stock Price Index (KOSPI) fell 27.87 points, or 0.9 percent, to close at 3,079.75 points.

Trading volume was moderate at about 1.8 billion shares worth some 18 trillion won (US$16.2 billion), with losers outnumbering gainers 510 to 339.

Foreigners sold a net 316 billion won, and institutions offloaded a net 459 billion won, while retail investors purchased a net 749 billion won.

The key stock index started with mild gains, as South Korea’s exports rose 16.7 percent on-year in the first 20 days of February on strong shipments of chips and autos.

Stocks fell, however, largely as foreigners sold in the fourth consecutive session amid lingering concerns over the U.S. Treasury yields hike, generated by signs of global economic rebound from the pandemic.

“The combined foreign and institutional selling kept the KOSPI down,” Kiwoom Securities analyst Seo Sang-young said.

“The local stock markets remain under selling pressure by the People’s Bank of China’s liquidity squeeze,” he said.
