• TSMC stock drops 6.6%, largest decline in six months
• Trump announces 25% tariffs on Mexico/Canada, 10% on China
• DeepSeek’s cost-effective AI model challenges high-capex assumptions
• Foreign investors sold $1.26 billion of Taiwan shares in January
What Happened?
TSMC shares experienced their sharpest decline in nearly six months upon resuming trading after the Lunar New Year holiday. The drop reflects both the global AI stock selloff triggered by DeepSeek’s breakthrough and new US tariff announcements. The broader Taiwanese market also suffered, with the Taiex falling 4.4% and key companies like Hon Hai Precision Industry dropping 9.2%. The Taiwanese dollar saw its largest intraday decline since 2015.
Why It Matters?
This market reaction signals a potential shift in the AI chip sector’s dynamics. DeepSeek’s development of cost-effective AI models challenges the assumption that significant capital expenditure is necessary for AI development, potentially impacting TSMC’s growth prospects as a key supplier to Nvidia and Apple. The addition of Trump’s tariffs, particularly the threat of specific semiconductor tariffs, creates additional uncertainty for the global chip supply chain. This is especially significant given TSMC’s dominant position in Taiwan’s market (39% of the benchmark) and its role in global technology manufacturing.
What’s Next?
Investors should monitor several key factors: the implementation and impact of US tariffs on the semiconductor industry, potential shifts in AI development strategies following DeepSeek’s breakthrough, and TSMC’s valuation metrics (currently at 18x forward earnings). While some analysts advocate reducing exposure to TSMC and Nvidia, others point to potential benefits from broader AI adoption driving demand for inference chips. The company’s fundamental strengths, including cutting-edge technology and reasonable valuation compared to peers like Intel (32x) and Nvidia (27x), may provide support. Recent positive demand signals from companies like Advantest and ASML suggest the broader AI chip sector remains robust despite near-term challenges.
