Valuation Metrics
Fundamental Analysis
Key Financial Insights: ⢠Expanding Margins ⢠Strong Liquidity ⢠High Capex TSM combines exceptional and improving margins, robust liquidity, and low leverage, but its capital intensity and premium valuation demand continued earnings execution.
Price Behavior
Key Price Behavior Insights: ⢠Above average ⢠Key resistance ⢠Elevated volatility Support Level: $428â$430 (stronger: $416â$418) Resistance Level: $438â$440 TSM is bullish over the last month, trading above its average with RSI near 61, but needs a break above $438â$440 to target $450 while holding $428â$430 support amid sharp volatility.
Sentiment & News
Key News Insights: ⢠AI Demand ⢠Capacity Constraints ⢠U.S. Expansion TSMC's AI-driven demand and advanced-node leadership support strong growth, but capacity, labor constraints, and costly U.S. expansion remain key margin risks.
AI Summary
TSMC's AI thesis has shifted from proving demand to converting sold-out leading-edge and packaging capacity into durable free cash flow: maintain exposure for its scarce technology moat, but monitor capex returns, Arizona execution, and margin pressure as new supply comes online.
