Taiwanese stocks rallied on the 21st, led by gains in MediaTek, TSMC, and ASE Technology, as investors shrugged off European geopolitical risks to push the index toward the 48,000-point mark.

What Happened

Semiconductor-Led Rally: Taiwan stocks showed strong resilience on the 21st, driven by a surge in semiconductor heavyweights. MediaTek climbed over 6% to cross the 5,000 TWD threshold for the first time, while TSMC and ASE Technology provided significant support to the broader market.

Strong Momentum in Packaging: Investor interest extended beyond major chipmakers to the testing and packaging sector. Nan Ya Printed Circuit Board (Nan Ya) hit its daily limit of 103 TWD, reflecting robust capital inflows into the semiconductor supply chain.

Geopolitical Resilience: Despite escalating tensions in the Russia-Ukraine conflict and rising security concerns in Europe, global markets have avoided a widespread sell-off. Instead, Asian markets have seen a rotation into technology and AI-related stocks, keeping the Taiwan index buoyant.

Approaching Key Resistance: The TAIEX index reached an intraday high of 47,728 points, putting the 48,000-point milestone back in focus. Market participants remain optimistic as long as the semiconductor sector continues to lead the index higher.
