Taiwan share prices edged up 0.30 percent Thursday as bargain hunters stepped in following recent falls, dealers said. The weighted index rose 20.41 points to 6,868.65 on turnover of 121.43 billion Taiwan dollars (3.7 billion US). Twenty-seven stocks surged to their daily 7.0 percent limit, against 26 limit- down. But losers outnumbered gainers 1,364 to 980, while 163 stocks remained unchanged. In volatile trade the market opened slightly up before dipping to an intraday low of 6,776.08 in the morning before drifting back to positive territory. 'This was a rebound following the recent falls,' said Allen Lin of Concord Securities. Having fallen below the 20-day moving average of 6,900 points, the market tested the 60-day moving average of around 6,685, he said. 'The market could continue to test the 60-day moving average next week,' Lin said. The bourse may close Friday depending on the path of Typhoon Morakot, which is expected to bring powerful winds and torrential rains over the weekend if it keeps its current course, Taiwan's weather bureau said.
