Taiwan's TAIEX Surges Nearly 8 Percent in Record Single-Day Rally

Tech Giants Lead Historic Rally

Taiwan's stock market posted its largest single-day points gain on record yesterday, with the benchmark TAIEX climbing 3,186.45 points to close at 43,119.75. The 7.98 percent surge marked the index's second-largest percentage gain in history, driven by a broad rebound in semiconductor and electronics shares.

Taiwan Semiconductor Manufacturing Co (TSMC) jumped by the daily limit of 10 percent, while chip designer MediaTek and semiconductor packaging firm ASE Technology Holding also hit their maximum allowed gains. The rally followed strength in global technology markets, particularly after US cloud service providers reported earnings that signaled sustained demand for AI infrastructure.

Turnover reached NT$833.7 billion (US$25.8 billion), down from the previous session, indicating that some investors remain hesitant despite the sharp upward move.

Foreign Capital Returns After Selloff

Foreign institutional investors returned as net buyers, purchasing NT$67.55 billion worth of shares, according to Taiwan Stock Exchange data. Domestic mutual funds added another NT$33.38 billion in purchases. Proprietary trading desks moved in the opposite direction, selling a net NT$16.26 billion.

The shift in positioning came after a multi-day correction that reduced margin financing levels and brought valuations down from recent peaks. Allianz Global Investors Taiwan noted that concerns over market fundamentals have begun to subside as US corporate earnings continued to demonstrate resilient demand patterns.

The recent decline helped ease worries about excessive leverage in the system, creating technical conditions for a rebound as vulnerable positions were cleared out.

Rate Policy and Earnings Drive Sentiment

Market volatility in recent sessions stemmed partly from uncertainty about US Federal Reserve monetary policy direction, according to Hsiao Hui-chung, a fund manager at Allianz Taiwan. With the Fed maintaining unchanged interest rates, investor attention has shifted back toward corporate earnings and the sustainability of AI-related capital expenditure.

Major US technology companies have increased their AI infrastructure spending in recent quarters, suggesting the sector is moving beyond early-stage investment and into tangible capacity expansion. This shift has helped restore confidence in the semiconductor supply chain that feeds into data center buildouts.

UOB Asset Management Taiwan said the long-term outlook for Taiwanese equities remains constructive, supported by continued AI investment, strong profitability among financial institutions, and steady demand from traditional industries. Fund manager Kuo Hsiu-cheng noted that the recent pullback brought valuations of many semiconductor and electronics companies back to more reasonable levels.

Regional Tech Rebound Broadens

The rally extended across Asian technology markets. South Korea's KOSPI surged as much as 18 percent, rebounding from a three-day selloff, with heavyweight chipmaker SK Hynix climbing by its 30 percent daily limit and Samsung Electronics rising as much as 27 percent. The two companies were the largest contributors to the MSCI Asia Pacific equities gauge.

The regional gains followed the biggest rally in Wall Street chip stocks in more than a year. NASDAQ 100 futures pointed to further advances after the tech-heavy index snapped a six-day losing streak.

However, the decline in turnover on the Taiwan exchange suggests conviction remains limited. Investors continue to monitor geopolitical tensions in the Middle East, which have contributed to volatility in global risk assets in recent weeks.

Sector Rotation and Valuation Reset

The correction preceding yesterday's rally helped reset positioning across Taiwan's technology sector. The unwinding of leveraged trades and automated selling had driven much of the recent decline, rather than deterioration in underlying corporate fundamentals, according to CTBC Securities Investment Service.

The current environment reflects a reassessment phase, where investors are evaluating which technology shares offer sustainable growth at reasonable valuations following the sharp run-up earlier this year. Semiconductor packaging, silicon photonics, and advanced manufacturing capacity remain areas of focus as AI infrastructure spending continues.

With major chipmakers scheduled to report quarterly results in coming weeks, market participants will be watching for guidance on order visibility and capital expenditure plans from hyperscale cloud customers. The trajectory of AI-related revenue growth will likely determine whether the current rebound can be sustained or if further consolidation lies ahead.
