South Korean stocks dipped almost 2 percent Thursday on massive foreign selling, generated by results of the Federal Open Market Committee (FOMC) meeting. The Korean won rose against the US dollar.

The benchmark Korea Composite Stock Price Index (KOSPI) fell 53.51 points, or 1.71 percent, to close at 3,069.05 points.

Trading volume was moderate at about 1.3 billion shares worth around 22.7 trillion won ($20.3 billion), with losers outnumbering gainers 768 to 114.

Foreigners sold a net 1.6 trillion won and institutions offloaded a net 382 billion won, while retail investors purchased a net 1.9 trillion won.

Foreign selling increased as the US Fed did not announce new measures to quicken the economic recovery, analysts said.

"Investors have paid keen attention to concerns of China's monetary tapering and the results of the (US) FOMC meeting results," Kiwoom Securities analyst Seo Sang-young said.

"The FOMC reassured that it is too early to discuss tapering, but investors seemed to have anticipated more than just the comments on recovery signals," he added.

Investors' profit-taking rush during the earnings report season also drove the KOSPI down.

In Seoul, top cap Samsung Electronics lost 2.22 percent to 83,700 won, and No. 2 chipmaker SK hynix dipped 4.28 percent to 123,000 won.

Internet portal giant Naver jumped 3.95 percent to 355,000 won, but its rival Kakao fell 1.51 percent to 458,000 won.

Bond prices, which move inversely to yields, closed higher. The yield on three-year Treasurys lost 0.5 basis point to 0.977 percent, and the return on the benchmark five-year government bond fell 0.6 basis point to 1.329 percent. (Yonhap)
