TSMC Faces Margin Pressure Amid AI Boom

TSMC’s June revenue rose 67.9% from a year earlier to NT$442.68 billion, underscoring how the AI buildout continues to fill order books. But the stock has become more volatile around the trade-off between surging demand and margin pressure, with shares closing at $424.61 on July 21 after briefly trading as high as $477.57 at the end of June, while the 50-day moving average has flattened near $425. Technical readings also show weakening momentum, with RSI at 32.3 and MACD below its signal line.

The market backdrop is still supportive for semiconductors. Nvidia, the clearest beneficiary of AI spending, closed at $207.29 on July 21, just under its 50-day moving average, after regaining traction from a June pullback. Adalytica’s NVIDIA Earnings Sentiment gauge sits at 95, or “Extreme Greed,” reflecting investors’ continuing appetite for AI exposure even after recent volatility.

But TSMC does not enjoy the same clean story. Adalytica’s TSMC Earnings Sentiment gauge has dropped to 21, labeled “Fear,” even as awareness remains elevated at 86, suggesting the market is closely focused on policy risk and margin compression rather than growth alone. That split captures the broader investor concern: AI demand is strong, but the economics of supplying it are getting tougher.

The pressure is also showing up in the sector itself. Intel shares jumped as high as $139.63 in late June before sliding to $105.45 on July 21, highlighting how quickly chip stocks are being repriced as investors weigh policy support, factory spending and execution risk. The U.S. Industrial Production index is forecast to edge up to 102.9436 in July, but that macro improvement does little to offset the capital intensity of the chip reshoring campaign.

TSMC remains the clearest winner from AI demand, but it is also becoming a test case for how much margin global chip leaders must surrender to stay aligned with U.S. industrial policy. The next catalyst is likely to be TSMC’s full earnings update, where investors will watch for commentary on U.S. capex, gross margin guidance and whether AI demand is still strong enough to absorb the higher cost of doing business.
