The TAIEX fell 39 points, or 0.1%, to 41,712 in Friday morning trade in a choppy session, erasing gains from the previous session and mainly weighed down by electronic technology and technology services. The decline came as traders took profits after the index closed in the green a day earlier and hit a record high last week amid a surge in tech sectors. Technology services dropped 1.4%, while electronic technology fell 0.2%, with Delta Electronics declining 1.6% after a 0.5% fall in the previous session. The index’s decline was partly capped by gains in TSMC, which accounts for more than 40% of the benchmark, rising 0.7%. However, a rally on Wall Street overnight, buoyed by strength in AI-related companies and optimism over the US-China summit, limited further downside. Traders also assessed remarks from U.S. Secretary of State Marco Rubio on Thursday that U.S. policy on Taiwan remains unchanged. Other early decliners included Wiwynn Corporation (-2.6%) and V5 Technology (-5.4%).
