Taiwan share prices closed down 0.45 percent Thursday as the high-tech sector continued to see profit taking, while select old economy stocks remained resilient, preventing the broader market from falling further, dealers said. The weighted index fell 34.95 points to 7,666.34, after moving between 7,665.78 and 7,718.92, on turnover of NT$87.54 billion (US$2.72 billion). The market opened little changed, down 1.93 points, and rotational buying in old economy stocks led the index to the day's high before profit taking in select electronics emerged to reverse the early gains after U.S. electronics stocks fell overnight. A total of 1,731 stocks closed down and 1,378 finished higher, while 354 remained unchanged. The biggest drop was in the construction sector which fell 0.7 percent. The financial, and machinery and electronics sectors closed each closed 0.6 percent lower, while the plastics and chemical sector fell 0.5 percent and the textile sector lost 0.2 percent. The paper and pulp sector rose 1.1 percent, the foodstuff sector gained 0.7 percent and cement sector added 0.6 percent. Wall Street moved lower overnight after Chairman of the U.S. Federal Reserve Ben Bernanke said the U.S. economic outlook remained 'unusually uncertain.' 'Despite the fall, the selling in the local bourse was not intolerable,' Concord Securities analyst Allen Lin said. 'Bernanke's comments did have some impact on the market here. But, the impact was limited as many investors expect the moderate growth rate of the global economy in the second half of this year,' Lin said. Lin said Thursday's selling focused on large cap high tech stocks amid earnings uncertainty before they report next week on their second quarter results. 'While that uncertainty remains, the high tech sector and even the broader market is expected to continue in a consolidation mode,' Lin said. Integrated circuit designer MediaTek dropped 1.95 percent to NT$453.00, flat panel AU Optronics fell 1.35 percent to NT$29.30 and smartphone maker HTC lost 0.89 percent, falling to NT$555.00. United Microelectronics Corp. fell 1.01 percent to NT$14.65, while Taiwan Semiconductor Manufacturing Co. closed 0.32 percent higher at NT$62.00. While some old economy stocks were boosted by rotational interest to lend some support to the broader market, Lin said their strength failed to help the index emerge from the current narrow range. Oceanic Beverages rose 6.95 percent to NT$25.40 and Taiwan Cement gained 2.74 percent to reach NT$28.10.
