Taiwan's benchmark TAIEX index fell 233 points, or 0.5%, to 44,695 in Tuesday morning trade, giving back the previous session's gains after a Wall Street decline and stronger oil prices clouded expectations for the Federal Reserve's monetary policy. The broader market slipped from its highest level since July 16, reached a day earlier, with electronic technology, finance, process industries and technology services leading the retreat. Electronic technology shares dropped 0.6% after a 2.1% rise in the previous session, with MediaTek down 0.9%, Delta Electronics off 0.3% and Hon Hai Precision losing 1.1%. TSMC, the world's largest contract chipmaker, bucked the trend with a 0.2% gain after rising 0.4% on Monday, and its size matters because it accounts for more than 40% of the market's total value.
