Capacity expansion as US partnership and insider buy spur confidence

TSMC has entered a 10-year agreement with Amkor Technology to expand advanced semiconductor packaging and testing capabilities in the United States, a move that secures long-term production capacity and enhances supply chain resilience for US-based high-tech sectors. By increasing packaging capacity in Arizona and establishing a fully US-based supply chain, the partnership addresses rising demand for artificial intelligence and high-performance computing chips, which is likely to boost TSM's market share among US customers. Additionally, a recent company filing reported that Vice President Lipen Yuan purchased 1,000 shares, raising his direct holdings to 4,000 shares, which generally reflects management’s confidence in the company’s outlook.

Bullish momentum persists as overbought signals and support converge

On the hourly chart, TSM trades above the MA-20 at $437.56 and MA-50 at $428.43, with price comfortably above the MA-200 at $333.93 on the daily timeframe. The Ichimoku Kijun sits at $440.39 and serves as immediate support. Key indicators present a mixed, but largely bullish, technical setup: MACD is on a Buy signal, ADX remains neutral indicating moderate trend strength, while RSI at 69.68 (Buy) and both the Stoch RSI and CCI show overbought conditions. BBP also registers as overbought, highlighting dominant buyer momentum intraday, and the Awesome Oscillator supports persistent upside bias. Notably, most oscillators reflect overbought conditions even as momentum readings remain positive, indicating some divergence.

Consolidation favored as volatility and breakout potential shape outlook

Over the next 2–3 trading days, the expected trading range for TSM lies between $448.11 and $470.02, reflecting typical volatility relative to the current price levels. The baseline scenario calls for price consolidation within this band, while a bullish move could see a breakout above resistance and continuation of the upward leg. Conversely, a close below immediate support at $440.39 would open the door to a short-term correction.

Viktoras Karapetjanc, expert at Traders Union, sees TSM’s recent corporate agreement and management share purchase as powerful signals of institutional confidence. He believes the expansion of US-based manufacturing significantly improves TSM’s strategic position in the global semiconductor sector. Strong price action and continued buyer momentum reinforce his optimism, but he notes the overbought technical readings. The expert expects bullish momentum to persist if support at $440.39 holds. "TSM’s fundamentals and sentiment are both positive — I see strength above $448.11, with bulls driving the current trend."

Earlier, analysts noted that TSMC's ongoing supply chain expansions and strategic partnerships were reinforcing its strong long-term growth outlook. Building on that view, the latest surge confirms robust bullish momentum, but with most oscillators now overbought, traders should closely monitor for a potential breakout above $470.02 or a corrective move below near-term support at $440.39.
