Taiwan's share prices extended losses across the board in mid-morning trade Tuesday after Wall Street fell to a three-month low amid concerns about the global economic outlook, dealers said. As of 10:34 a.m., the weighted index had fallen 167.88 points, or 2.29 percent, to 7,154.85 on turnover of NT$37.90 billion (US$1.18 billion), after opening 1.15 percent lower. 'Investors rushed to dump their holdings on fears that debt problems in Europe will escalate and undermine the world's economic recovery, ' Taiwan International Securities analyst Michael Chiang said. Chiang said declines in other regional markets, such as Japan and South Korea, also dealt a blow to the local bourse as investors were concerned about the tense political standoff in the Korean Peninsula. 'Judging from the current downward trend, yesterday's gains were just technical,' Chiang said. 'The market has become technically weak. It is possible for the index to fall further,' Chiang said. As of mid-morning, Hon Hai Precision was down 3.39 percent to NT$128.00, United Microelectronics Corp had fallen 2.80 percent to NT$13.90 and Taiwan Semiconductor Manufacturing Co. had lost 1.32 percent to NT$58.40.
