On August 24, Taiwan Semiconductor Manufacturing declined 3.07% in regular trading, trading at $406.25/share, with turnover of $1.222 billion. The decline came amid broad-based selling pressure across the semiconductor sector.

The semiconductor industry experienced widespread weakness, with major peers posting significant losses: Micron Technology fell 7.66%, Intel dropped 4.62%, Marvell Technology declined 4.70%, Advanced Micro Devices lost 4.11%, and NVIDIA slipped 2.49%. The sector-wide selloff follows a pattern of recent volatility, as the Philadelphia Semiconductor Index had already suffered a nearly 5% decline earlier in the week driven by profit-taking in storage chips and broader tech weakness amid rising bond yields and inflation concerns.

Despite constructive fundamental developments including reports of TSMC's planned NT$30 billion-plus acquisition of two panel factories for advanced packaging expansion, A16 process readiness for Q4 mass production, and continued CoWoS capacity tightness, the stock was unable to escape the sector-wide risk-off sentiment.
