The current thesis for AI '25: Semis & Memory is bullish, driven by the continued expansion of AI applications requiring advanced semiconductor technologies and high-performance memory solutions. With the rapid growth of AI applications, companies like TSMC (2330 TT) and SK Hynix (000660 KS) are well-positioned to capitalize on the increasing demand for customized chips and high-bandwidth memory (HBM). The thesis anticipates robust growth as AI deployment continues to scale, requiring substantial advancements in semiconductor manufacturing and memory capacities.
TSMC's leadership in producing advanced nodes (e.g., 3nm and 5nm) positions it uniquely to meet the rising demand for AI-specific chips.
SK Hynix benefits from the growing need for high-performance memory solutions, particularly HBM, which is crucial for AI processing tasks.
Expanding AI applications across industries drive continuous demand for semiconductors and memory, supporting revenue growth for both companies.
Increasing competition from emerging semiconductor companies could pressure market share and margins for TSMC and SK Hynix.
Geopolitical tensions, particularly involving Taiwan, may disrupt TSMC's production capabilities and supply chain.
