The long thesis holds (August sales +53% YoY, Q3 earnings 10/14), but 21.5% breaks the 12% position limit. Cut to 8% to reduce overlap with other chip holdings.
Thesis (long, position, conviction 66)
Bull: TSMC is compounding revenue at an extraordinary rate — August 2026 sales up 53.3% YoY and Jan–Aug up 39.3% YoY (F-TSM-5, F-TSM-6) — driven by the AI/advanced-node buildout, and management is backing that demand with over $29B in newly approved capex for advanced-technology, packaging and real estate capacity (F-TSM-7), signalling confidence in a multi-year growth runway rather than a one-off spike. Q2 2026 EPS beat by nearly 11% (F-TSM-9), and Q3 (Oct 14) carries a further-raised EPS estimate of ~28.96 (F-TSM-10), giving a credible near-term catalyst. Technically the stock is in a clean uptrend, trading above its 20/50/200-day averages (433/421/383) with RSI 65 — firm but not extreme (F-TSM-4) — and sits only ~4% below its 52-week high after a healthy 3-month digestion phase (F-TSM-2, F-TSM-3), which has reset short-term momentum without breaking the trend. A resumed dividend payment on Oct 8 (F-TSM-8) adds a modest income cushion.
Bear: The stock has underperformed the S&P 500 by 6.65 points over 3 months despite the AI narrative (F-TSM-3), suggesting some rotation out of semis or growth-expectations fatigue after a 69% 12-month run. Valuation is elevated and internally inconsistent in the data (trailing P/E 33.97 per Yahoo vs 28.32 per Finnhub — F-key_metrics), an unreconciled gap that makes it hard to pin down exactly how expensive the stock is; dividend-yield figures are similarly inconsistent, pointing to data-quality gaps rather than resolved facts. No annual SEC financial statements were available to sanity-check margins or free cash flow independently. Capex of $29B+ (F-TSM-7), while bullish for demand, also raises the bar for returns on invested capital and could pressure near-term free cash flow if AI capex growth decelerates. The position is already a large 21.5% portfolio weight, so the marginal risk/reward of adding is inferior to a fresh position, and any Q3 earnings miss against the raised 28.96 estimate (F-TSM-10) would likely hit a stock priced for continued beats.
Valuation: At ~28-34x trailing earnings (source-dependent) against 39-53% YoY revenue growth and continued double-digit EPS beats, TSMC's multiple is undemanding relative to its growth rate — a PEG comfortably under 1 by most readings — though the brief lacks reconciled FCF-yield or margin detail to fully validate the P/E discrepancy between Yahoo and Finnhub. On balance, growth this fast at this multiple is not obviously overvalued, but the data gaps warrant only a moderate-conviction rather than high-conviction valuation call.

Q3 2026 EPS reported below ~26 (a miss versus the 28.96 estimate) or management guiding down capex/demand for advanced nodes
Revenue growth decelerating sharply below ~20% YoY in the next monthly print, breaking the recent 40-53% YoY trend
Data quality
Quality score 96/100.
Gap: The SEC annual financials tool returned an empty annual dataset.
Gap: The fundamentals block reports different trailing P/E values from Yahoo and Finnhub (33.97 versus 28.32); the discrepancy is not reconciled.
Gap: The fundamentals block reports different indicated dividend yields from Yahoo and Finnhub (0.9% versus 1.99301%); the discrepancy is not reconciled.
