South Korean shares fell on Wednesday as investors took a wait-and-see stance ahead of announcements of the country's gross domestic product and major companies' first-quarter earnings. The benchmark Korea Composite Stock Price Index (KOSPI) fell 3. 85 points, or 0.19 percent, to close at 2,000.37. Trading volume stood at 231.74 million shares worth 3.82 trillion won (3.68 billion U.S. dollars). The first-quarter GDP of South Korea will be unveiled on Thursday. It will show whether the economy's recovery lasted. Top automaker Hyundai Motor will report its first-quarter earnings the next day. The world's largest smartphone maker Samsung Electronics and its smaller rival LG Electronics will unveil earnings for the first quarter next week.
