South Korean stocks closed lower Friday largely from weaker-than-forecast earnings by major companies and net selling by foreign investors and institutions, analysts said. The Korean won was down against the greenback. The benchmark Korea Composite Stock Price Index (KOSPI) gave up 7.03 points, or 0.36 percent, to 1,940.56. Trading volume was low at 274.2 million shares worth 4.29 trillion won (US$3.98 billion), with losers outpacing gainers 482 to 303 on the second day of losses.
