South Korean shares ended slighter lower in choppy trading on Friday as foreign and institutional investors took profits amid lack of momentum following the wrap-up of the second-quarter earnings season. The benchmark Korea Composite Stock Price Index (KOSPI) fell 3. 26 points, or 0.17 percent, to close at 1,880.71. Trading volume stood at 276.67 million shares worth 3.47 trillion won (3.12 billion U.S. dollars). The KOSPI moved in a narrow range throughout the session before closing the trade slightly lower amid lack of momentum. Market watchers said investors sat on the sidelines following the end of the second-quarter earnings season. Foreign and institutional investors sold shares worth 41.2 billion won and 3.1 billion won each, seeking to lock in recent profits. Retail investors bought a net 47.1 billion won worth of stocks, limiting the KOSPI\'s further decline. Concerns remained over an early exit of U.S. quantitative easing.
