Taiwan Market Opens Lower as Semiconductor Selloff Hits Chipmakers
TSMC and Delta Electronics provided temporary support as the weighted index struggled near 45,900, following a 5.86% plunge in the Philadelphia Semiconductor Index and heavy institutional outflows.
Taiwan’s stock market opened lower on the 15th, with the weighted index starting at 45,847.27 after a 322-point decline the previous day. The session was defined by volatility, as the index traded in a narrow band between 45,800 and 45,900. Investors reacted to a 5.86% drop in the Philadelphia Semiconductor Index and rising U.S. Treasury yields, which dampened risk appetite for high-growth tech assets.
TSMC (2330.TW) opened higher at NT$2,405, serving as the primary stabilizer for the broader market. Delta Electronics (2308.TW) surged more than 3% intraday, briefly pushing the index to 45,946.32. However, weakness in other major names, including MediaTek, ASE Technology, and Hon Hai, prevented a sustained rally, causing the index to dip to 45,729.83 before stabilizing.
Institutional Selling Drives Market Correction
The previous session saw a sharp contraction in trading volume to NT$631.767 billion, the lowest in five months. Institutional investors were net sellers of NT$48.361 billion, with foreign investors accounting for NT$36.964 billion of that outflow. Proprietary traders sold NT$15.093 billion, while investment trusts bought NT$3.696 billion. This net outflow coincided with a drop in TSMC ADRs by 3.52% and ASE ADRs by 6.06% in U.S. markets.
Technical indicators have weakened, with the KD and RSI metrics declining and the MACD turning negative. The 5-day and 10-day moving averages are showing signs of downward pressure. Analysts report that the market is in a short-term consolidation phase, characterized by choppy price action and reduced liquidity as traders assess the impact of cooling AI capital expenditure expectations.
Passive Components See Sector Rotation
A distinct rally emerged in the passive components sector, driven by reports that Murata Manufacturing plans to expand MLCC production capacity by over 20%. This news spurred gains in Taiwanese suppliers, with Prosperity Dielectrics and Holy Stone Enterprise rising more than 4%. Other names, including Yageo, Lelon Electronics, and Dafon Electronics, posted gains between 1% and 2%, indicating a rotation into hardware supply chain plays.
Cybersecurity stocks also attracted significant buying interest, with Azion Technologies, China Communications Media Group, and Sysage Technology hitting their daily limit-up. Chunghwa Telecom Security gained 6%, while Acer Cyber Security rose over 5%. This strength in security and networking sectors provided a counterweight to the weakness seen in plastics, oil and gas, and green energy sectors during the session.
Market Sentiment Remains Cautious
According to GN stocks/chips, the overall market atmosphere remains defensive. While specific subsectors like biotech and electronic components showed resilience, the broader market lacks momentum. The disparity between the strength in TSMC and Delta Electronics and the weakness in other large-cap tech firms highlights a fragmented market structure where investors are selectively reallocating capital away from high-beta semiconductor plays.
The session underscored the sensitivity of Taiwan’s market to global semiconductor trends and macroeconomic signals. With U.S. indices closing lower and oil prices rising, the local market faces continued pressure to maintain its support levels. Traders are monitoring volume trends and institutional flow to determine if the current consolidation phase will lead to a recovery or a deeper correction.
