SEOUL, Sept. 17 (Yonhap) — South Korean stocks decreased more than 1 percent Thursday, as more investors turned to profit-taking that stemmed from tech valuation concerns. The Korean won rose against the U.S. dollar.

The benchmark Korea Composite Stock Price Index (KOSPI) dropped 29.75 points, or 1.22 percent, to close at 2,406.17.

Trading volume was moderate at about 834 million shares worth some 13.9 trillion won (US$11.8 billion), with losers outnumbering gainers 655 to 200.

Foreigners sold a net 126 billion won, while retail investors purchased a net 457 billion won. Institutions dumped a net 334 billion won.

The KOSPI dropped for a second straight session on profit-taking.

“Profit-taking intensified among certain stocks that hitchhiked on the recent rally without improved fundamentals,” Kiwoom Securities analyst Seo Sang-young said.

Despite the U.S. Federal Reserve’s signal to keep the near-zero rate till 2023, the local stock market remained bearish.

“The fact that the FOMC did not signal additional asset-buying seems to have disappointed investors who hoped for larger liquidity in the markets,” Bookook Securities researcher Lee Won said.
