SEOUL, Jan. 10 (Yonhap) -- South Korean shares closed lower Thursday as investors engaged in profit taking, with the U.S. and China wrapping up three days of trade talks without tangible results.
The benchmark Korea Composite Stock Price Index fell 1.43 points, or 0.07 percent, to 2,063.28. Trading volume was moderate at 375.68 million shares worth 5.27 trillion won (US$4.7 billion), with decliners outnumbering gainers 471 to 330.
Foreigners bought a net 273.51 billion won worth of stocks, with institutions and individuals offloading 267.11 billion won worth of shares.
The main index declined, having gained 1.95 percent in the previous session, on optimism that Washington and Beijing may reach an understanding of some sort.
