On July 29, Taiwan Semiconductor Manufacturing fell 3.04% in regular trading, trading at $380.69/share, with turnover of $1.38 billion.

On the news front, a 7.1 magnitude earthquake struck Kumamoto Prefecture, Japan on July 28, putting TSMC's JASM wafer fab to its first major seismic test. The company confirmed that water supply, power, and safety systems are operating normally, raw material supply is unaffected, and construction work has resumed. However, equipment inspection and calibration are expected to require considerable time, and full recovery of the fab still needs additional time. TSMC stated it is evaluating the earthquake's impact and maintaining close communication with affected customers. Analysts noted that car-grade chips and image sensor delivery timelines face near-term uncertainty, potentially pushing up power semiconductor price expectations.

Meanwhile, the broader semiconductor sector remained under pressure. Within the sector, Micron Technology fell 4.15%, Advanced Micro Devices fell 4.80%, NVIDIA fell 2.96%, Intel fell 2.99%, and SK hynix fell 0.52%.
