TSMC shares rise ahead of closely watched Q3 earnings

TSMC shares rose 1.4% to T$2,525 as investors awaited results; analysts forecast Q3 net profit of T$746.3 billion ($23.4 billion), up 65% year over year, after the company reported revenue of T$1.49 trillion, up 50%. TSMC expects 2026 revenue growth of more than 40%, though its $265 billion U.S. expansion may weigh slightly on margins. ASML reported stronger-than-expected Q3 sales and revenue and reaffirmed its full-year outlook, but said planned supply for 2027 and 2028 may not meet customer demand.

Analysis

The key signal is not simply strong AI demand; it is that capacity is becoming the scarce input. If ASML’s customer-demand warning translates into delayed tool deliveries, foundry output may lag chip demand even as TSMC raises capex. That can support pricing and utilization at existing nodes, but it also raises execution risk: Arizona ramp costs can arrive before saleable capacity, leaving near-term margins exposed. NVIDIA benefits only if constrained wafer and packaging supply converts into shipments; demand strength alone does not establish incremental revenue.

Over days, earnings and guidance are the catalyst, but expectations appear demanding and the reported results may be less important than TSMC’s capacity, margin, and delivery commentary. Over 1–3 months, track tool lead times, TSMC utilization and gross-margin guidance, and whether customers secure capacity through firmer commitments. Over 6–18 months, persistent equipment constraints could shift value toward scarce manufacturing capacity and away from chip designers unable to ship; faster tool supply or weaker AI investment would reverse that dynamic.

Contrarian angle: the article frames capacity expansion as a response to demand, but capex is not equivalent to near-term output. The market may underprice the lag and ramp-cost risk, while over-crediting demand forecasts that have not yet become delivered systems. No valuation or positioning data are supplied, so avoid chasing an event-driven move.

Key Decisions for Investors

• TSM: Prefer entry after the earnings reaction, conditional on management maintaining demand visibility while giving a credible margin and capacity-ramp path. Falsify the thesis if utilization or margin guidance deteriorates materially, or customer commitments weaken.
• ASML: Hold rather than chase the positive read-through. Its constrained 2027–28 supply is a potential scarcity advantage, but confirmation in order intake, backlog conversion, and delivery capacity is needed before adding exposure.
• NVDA: Do not infer a fresh long signal from foundry demand alone. Track wafer allocation and delivered-system growth; a widening gap between demand commentary and shipments would weaken the AI earnings case.
• Alert: Monitor tool lead times and TSMC capex-to-output conversion over the next 1–3 months. If delays persist while utilization and pricing hold, favor foundry capacity exposure over less supply-secure AI beneficiaries; if tool supply catches up or AI spending is revised down, reassess.
