TSMC just made the bull case simpler: this is no longer only an AI exposure story, it is a supply-constrained tollbooth story. CEO C.C. Wei said it will take a “very long time” to fully satisfy customer demand, and that matters because scarcity at the leading edge is where pricing power and margin durability live. The market is paying up for that position, but not irrationally so when revenue is still growing 33.0% year over year and EPS is growing 44.3%. A TickerSpark Score of 92 says the same thing in one line: elite business quality, elite momentum, and still-reasonable growth-adjusted valuation.
The cleanest reason to stay bullish is that TSMC is selling what the market cannot get enough of. Management raised full-year revenue guidance in April and said AI-related demand remains “extremely robust,” while May revenue still climbed 30.1% year over year. That is not the profile of an AI trade running on hope. It is the profile of a foundry with real order visibility and customers still fighting for capacity.
The second point is that the business is converting that demand into unusually strong economics. Gross margin sits at 61.9%, operating margin at 53.2%, and net margin at 47.0%, which is exceptional even inside big tech. Against peers, that stands out: Broadcom posts a 38.8% net margin, ASML 29.7%, and Micron 41.5%. TSMC is not merely growing fast; it is doing it with the kind of profitability that usually belongs to software, not manufacturing.
The third point is that the stock still has room to justify itself because growth is outrunning the headline multiple. TSM trades at 30.32 times trailing earnings with a PEG of 0.64, while revenue growth is 33.0% and net income growth is 49.8%. That looks much more compelling next to AVGO at 62.91 times earnings and ASML at 58.59 times. Add in the operating execution — seven straight quarterly earnings beats, including an 8.4% beat in April — and this still looks like a premium name earning its premium.
The pushback is real enough: scarcity power can fade if the capex wave catches up. TSMC is spending aggressively to add capacity, and if supply ramps faster than expected in 2027 and 2028, today’s bottleneck could become tomorrow’s normalization. There is also concentration risk embedded in the AI buildout, because a handful of hyperscalers and chip designers still drive a large share of the demand narrative.
That said, the current setup still favors the bulls because the shortage is not theoretical. Management is openly saying demand remains ahead of supply, customers are still signaling capacity constraints, and the mix is moving deeper into advanced nodes, with 3nm already about a quarter of Q1 sales versus just 6% in Q3 2023. The risk is that this eventually cools; the evidence in front of the market says it has not cooled yet.
That keeps us constructive on TSM even after a huge run. The stock is down 2.5% today, but it remains above both its 50-day and 200-day moving averages, has outperformed the technology sector by 6.9 percentage points year to date, and still shows accumulation in the tape. This does not read like a broken leader. It reads like a leader digesting gains while the fundamental story keeps improving.
What we would watch now is simple: the next earnings report, any update on 3nm and 2nm capacity, and whether management still describes demand as structurally ahead of supply. If that language softens, the scarcity thesis weakens fast. Until then, TSM looks like one of the clearest ways to own the AI buildout without betting on a single chip designer, because the shortage itself is part of the moat.
