November Revenue Report Reaction

TSMC announced its November 2025 revenue on December 10, reporting NT$343.61 billion (approximately $10.9-$11 billion). This figure dropped 6.5% from October's all-time high.

Algorithmic trading and short-term sellers viewed this month-over-month decline as a sign of weakening demand, triggering sell-offs. In reality, year-over-year revenue grew 24.5%, and cumulative January-November sales surged 32.8% to NT$3,474.05 billion.

Understanding the Seasonal Dip

The monthly drop aligns with typical patterns in the semiconductor cycle.

• Smartphone and PC manufacturers, including Apple, build inventory heavily in September-October for holiday sales.

• Demand naturally slows in November as stockpiles suffice for the season.

• High-performance computing (HPC) and AI segments provide steady, non-seasonal growth.

This explains why November figures appear softer despite overall strength.

TSMC Remains On Track for Q4 Guidance

TSMC guided Q4 2025 revenue at $32.2-$33.4 billion. October-November combined totaled around $22.6 billion, requiring only about $9.6-$10.8 billion in December to meet or exceed targets.

Recent monthly revenues consistently surpass these levels, making a beat likely amid robust AI orders.

Additional Factors Contributing to TSM Stock Decline

Broader concerns have amplified the pullback. Geopolitical tensions, including U.S.-China export restrictions tightening after December 2025, raise uncertainty.

Expansion of overseas factories in Arizona, Japan, and Germany increases costs, potentially pressuring gross margins by 3-6 points long-term. After a strong 2025 rally, profit-taking emerged amid fears of AI spending slowdowns and elevated valuations around 29-30x forward P/E.

Strong Fundamentals Supporting Recovery

Positive indicators counter the negativity. HPC now comprises over 57% of revenue, overtaking smartphones and underscoring structural AI demand.

Management signals confidence through planned dividend growth, with quarterly payouts supporting a yield around 0.8-1.2%. Gross margins stay healthy near 59-60%, backed by year-to-date revenue growth over 30%.

Is TSMC a Good Buy Right Now?

Analysts largely view the dip positively. Consensus ratings lean toward Buy, with average price targets around $350-$370, implying 20-30% upside from current levels.

The pullback creates an attractive entry for those betting on the ongoing AI supercycle, where TSMC holds a near-monopoly in advanced nodes.

Impacts on Investors and the Semiconductor Sector

Short-term volatility affects day traders sensitive to headlines. Long-term investors gain from TSMC's essential role in AI infrastructure.

The drop highlights risks in tech stocks but reinforces TSMC's resilience against cyclical swings.

FAQ

Why did TSM stock drop despite strong yearly growth?

The drop was driven by a month-over-month revenue dip in November, which triggered short-term selling, even though year-over-year growth stayed above 24%.

No. The decline followed a typical semiconductor seasonal pattern after October inventory builds, not a structural demand issue.

Is TSMC still on track to meet Q4 revenue guidance?

Yes. October–November revenue already covered most of Q4 guidance, leaving a very achievable December target.

How does AI demand affect TSMC’s long-term outlook?

AI and HPC now generate over 57% of revenue, providing non-seasonal growth and reinforcing TSMC’s dominance in advanced chip nodes.

What are the main risks pressuring TSM stock right now?

Valuation concerns, geopolitical tensions, and margin pressure from overseas fabs are weighing on sentiment, despite solid fundamentals.
