SEOUL, Jan. 27 (Yonhap) — South Korean stocks slumped after a choppy session Wednesday, largely due to heavy foreign selling related to concerns over fiscal policy tightening in major financial markets. The Korean won rose against the U.S. dollar.

The benchmark Korea Composite Stock Price Index (KOSPI) fell 17.75 points, or 0.57 percent, to close at 3,122.56 points.

Trading volume was moderate at about 905 million shares worth some 19.4 trillion won (US$17.6 billion), with losers outnumbering gainers 574 to 293.

Foreigners sold a net 623 billion won and institutions offloaded a net 397 billion won, while retail investors purchased a net 1.06 trillion won.’

The KOSPI got off to a muted start ahead as investors waited for the results of the U.S. Federal Reserve’s policy meeting, and losses widened in the afternoon.

Faster-than-expected recovery in the Chinese economy also raised worries that emerging economies may hasten the tightening of their fiscal policies.

“Foreigners (had bought because they) have been optimistic about (a fast recovery in) South Korea’s economy,” Eugene Investment & Securities analyst Huh Jae-hwan said.

“But the recent hike in China’s short-term interest rate seems to have made them wary,” he added.
