TSMC Arizona Buildout Meets Profit-Taking

The market, though, is already pricing in a lot of that promise. TSMC shares closed at $398.37 on July 17, down from $419.48 the prior session and well below the late-June peak of $477.57, after a sharp run that left the stock below its 50-day moving average at $425.19. Relative Strength Index readings near 39 suggest the pullback is easing overbought conditions, while the recent downside break in MACD points to momentum unwinding.

That matters because TSMC’s investment plan is not a one-off headline. The company reported a record 77% jump in second-quarter profit, underlining how much of the current semiconductor cycle is being driven by AI demand rather than broad-based electronics recovery. June revenue rose 67.9% from a year earlier to NT$442.68 billion, reinforcing that the spending backdrop remains strong even as the stock corrects.

The move also lands in the middle of a broader rerating across the chip complex. Nvidia, the clearest proxy for AI compute demand, has also backed off recent highs, while the SOXX semiconductor ETF has slid from above 650 in late June to 521.81 on July 17, reflecting profit-taking across the sector rather than a TSMC-specific problem.

For investors, the key question is whether the Arizona expansion is a sign of durable earnings power or a capital-intensive step that caps near-term margin upside. The answer likely depends on how quickly TSMC can convert US investment into higher-volume, higher-margin advanced-node production while keeping AI demand hot.

Near term, the stock may need time to digest the gains. Longer term, the combination of record profits, AI-led demand and a larger US footprint keeps TSMC positioned as one of the most strategically important names in global semiconductors, with upcoming earnings updates and progress on Arizona the next catalysts to watch.
