Taiwan stocks declined 0.22 percent on Wednesday morning, though battered computer vendor Acer Inc surged on an upbeat forecast for the PC industry by chip giant Intel Corp. As of 0145 GMT, the main TAIEX index was down 21.19 points at 9,547.98, trailing other regional bourses, after hitting a seven-and-a-half-year intraday high in the previous session. It had closed 0.5 percent higher on Tuesday.
Electronics fell 0.18 percent. US Fed chair Janet Yellen on Tuesday said social media and biotechnology firms are overvalued, sending the tech-based Nasdaq Composite lower. But beleaguered computer maker Acer rose 4.54 percent.
