Taiwan's weighted index opened at 47,981.04 and climbed more than 880 points intraday to a record high of 48,601.53, extending the previous session's 538.09-point advance. Taiwan Semiconductor Manufacturing rose NT$30 to NT$2,510, MediaTek surged more than 7% to briefly reach NT$5,365, and Delta Electronics gained NT$55 to NT$1,930. The rally followed strong gains on Wall Street, including a 4.29% jump in the Philadelphia Semiconductor Index and a 2.26% rise in the Nasdaq Composite. Analysts said improving U.S.-China trade negotiations, lower oil prices, foreign net buying and reduced futures short positions were bringing funds back into technology shares. A short squeeze, when traders buy to cover bearish positions, is a key near-term focus as volume expands. AI, semiconductors, optical communications, display panels, solar power and data-center investment are providing additional sector support, although volatility may increase ahead of the Mid-Autumn Festival and Teachers' Day long weekend.
