Expansion raises margin concerns as Arizona investment accelerates

TSMC's announcement of an additional $100 billion investment in Arizona, as reported by Nytimes, marks a significant expansion of its U.S. manufacturing capacity through the construction of four new chip plants and related facilities. This move establishes a substantial long-term presence and is aimed at supporting expected demand for advanced 2-nanometer logic chips and AI hardware, but also increases the company's capital intensity and raises questions about future margin stability. In its latest reporting, TSMC delivered record revenue of $40.2 billion with a 36% year-over-year increase and a 77% jump in net profit to NT$706.6 billion, according to Euronews. The expanded Arizona project is supported by the U.S. CHIPS Act, positioning TSMC for advanced chip manufacturing leadership in the U.S. market—though price action has remained under broader selling pressure.

Bearish momentum intensifies as moving averages breached and sellers dominate

TSM closed below the 20-day ($410.28) and 50-day ($423.02) moving averages but held above the 200-day level at $351.08. Closest resistance sits at the Ichimoku Kijun line of $411.04. On the hourly chart, both the Moving Average Convergence Divergence (MACD) and Average Directional Index (ADX) confirm prevailing bearish momentum, while the Relative Strength Index (RSI) at 34.05 and Commodity Channel Index (CCI) readings signal oversold conditions. The Stochastic RSI remains neutral, with the Bull/Bear Power showing strong seller dominance intraday and the Awesome Oscillator confirming the downward sentiment. Price action included a $16.56 gap from the prior close and moderate volatility.

Downside risk grows as volatility band widens and resistance holds

In the coming sessions, TSM is expected to trade between $381.39 and $412.19, forming a volatility band relative to current levels. Further downside is probable, while a rebound scenario would require a decisive move above resistance around $411. If broad selling pressure persists, the stock could test new support areas below the recent range; consolidation is the base case in the near term.

Viktoras Karapetjanc, expert at Traders Union, sees TSMC’s sharp U.S. investment and record financial results as a strong signal of structural growth and global ambition. He notes that while the stock faces near-term technical pressure and margin concerns, the fundamental and macro factors remain constructive. Expanded U.S. policy support and robust revenue numbers reinforce the long-term opportunity, despite immediate volatility. "TSMC’s latest moves show bold confidence in future chip demand, and I expect pullbacks to attract high-conviction buyers if fundamentals stay strong."

Earlier, analysts noted that broad U.S. equity outflows were driven by profit-taking in semiconductor names and intensifying geopolitical risks. TSMC's latest price action and momentum indicators reinforce prevailing sector weakness, making sustained closes above $411 a crucial signal for any potential reversal.
