Taiwan Semiconductor is world's leading pure-play semiconductor foundry with major customers including Apple, Nvidia, AMD. Dominates advanced node manufacturing (3nm, 5nm) with ~70% market share.

Q4 2025 earnings: $34B revenue (up 25.5% YoY), EPS $3.14 beat estimates. Gross margin 62.3%, net margin 48.3%. Guides for ~30% revenue growth in 2026 with $52-56B capex.

High performance computing (AI/data center) represents 55% of revenue, smartphones 32%. AI demand is the biggest growth engine.

Valuation concerns: forward PE 31.25 vs 5-year average 22.5, potentially limiting upside despite strong fundamentals.

Risks: production constraints, cyclical AI demand, geopolitical tensions (US-China), high overseas fabrication costs, export restrictions.

Technical picture: TSM at $350 after earnings surge, breakout continuation setup, bullish as long as breakout holds.

RSI elevated (upper 60s to mid-70s daily, above 77 weekly), suggesting near-term overbought conditions and potential consolidation toward 20-week moving average.

Despite macro risks, TSM's leadership, scale, and global footprint position it at center of semiconductor/AI growth with geographic diversification enhancing supply resilience.
