TSMC (TSM)
The desk's stance
In the Buy Zone since Oct 15, 2026, on the G-Street slate.
Sub-3nm foundry monopoly printing 50% net margins at 17.9x forward P/E; CoWoS moat makes this an undeniable table-pounding buy.
Buy Zone limit $473.
What the company does
The world’s largest chip foundry. Designs nothing itself — it takes blueprints from Nvidia and Apple and physically etches them onto silicon. Crucially, it owns CoWoS, the exclusive packaging tech that fuses Nvidia’s GPUs and HBM memory into one module.
Why it matters: Every advanced chip in this web funnels through TSMC’s fabs and packaging lines. Even the memory makers ship to TSMC, not to Nvidia directly.
Outlook: Q2 2026 net profit surged 77% YoY to $40.2B; raised full-year sales growth guidance above 40%. Capex scaling to $60–64B, including a $265B multi-fab expansion in Arizona to hedge geopolitical risk.
In short: Pure-play dedicated contract semiconductor foundry. Category: Leading-Edge Semiconductor Foundry Monopoly. Sector: Technology, Semiconductors.

Our current thesis
Updated Oct 16, 2026
The thesis
- Accelerating QoQ revenue momentum and 50% net margins reflect uncontested sub-3nm AI foundry leadership.
- Undemanding 17.9x forward P/E trades at a sharp discount to fabless hyperscaler and designer peers.
- Indispensable fabrication bottleneck for NVDA and AAPL reinforced by proprietary CoWoS packaging capacity moats.
Risks
- Cross-strait geopolitical friction and expanding US export restrictions impose structural terminal valuation discounts.
- Surging capital expenditures for overseas fabs risk near-term depreciation drag and margin dilution.
- High customer concentration leaves utilization rates vulnerable to fabless client chip inventory adjustments.
What we're watching
- Support defense around the $400-$415 level after a 13% two-week sector pullback.
- Yield trajectory and client tape-outs for high-volume 2nm production and A16 nodes.
- Full-year 2027 capex guidance and gross margin drag updates on Arizona operations.
Latest
TSM trades at $412.61 (17.9x forward P/E, $2.14T market cap), consolidating 15.4% below its 52-week peak of $487.47 amid broader semiconductor sector volatility and capex concerns. Top-line growth accelerated quarter-over-quarter to 17.6% in Q3 2026 (NT$1.49T), driven by 64.2% gross margins and 49.9% net margins alongside four straight EPS beats. Fourth-quarter revenue consensus sits at NT$1.70T (+62.7% YoY) on relentless 3nm and emerging 2nm AI accelerator demand.
Key numbers
As of Oct 16, 2026: market cap $2.14T · revenue growth +50.9% year over year · gross margin 65.8% · net margin 51.1% · forward P/E 17.6 · next earnings Jan 14, 2027.

Decision history
- Oct 15, 2026 — Holding → Buy Zone at $422.25. Undisputed sub-3nm AI foundry bottleneck printing 50% net margins at an absurd 18.9x forward P/E; pound the table and add here.
- Sep 24, 2026 — Buy Zone → Holding at $451.15. Using the September 24 reference close of $451.15, TSMC is about 7% above our $420.39 entry. Q2 revenue rose 36% in New Taiwan dollars, with a 55.6% net margin, and 2nm accounted for 3% of wafer revenue, so the position stays. The system G-Street Value of $566.67 rests on three June and July analyst targets whose sources are not verified, and the USD-ADR basis of those targets has not been checked, so we do not describe this as a discounted entry. Hold while those inputs are verified.
- Aug 8, 2026 — Holding → Buy Zone at $420.04. Opened flat with 28% to our value — the 2nm monopoly at entry prices is a buy, not a hold.
On the Gainz Lab maps
Who it does business with
- ASML Holding supplies TSMC — EUV machines (about $15.0B a year). ASML sells 100% of the advanced EUV printing machines TSMC needs to manufacture Nvidia’s chips.
- Applied Materials supplies TSMC — Deposition & etch tools (about $8.0B a year). Applied’s deposition, etch and CMP tools build the layers on every TSMC wafer that ASML’s machines print — and its packaging tools stack HBM beside the GPU die.
- Micron supplies TSMC — HBM memory (about $35.0B a year). Micron ships finished HBM memory blocks to TSMC’s packaging facilities — not to Nvidia directly.
- SK hynix supplies TSMC — HBM memory (about $45.0B a year). SK hynix supplies cutting-edge memory stacks to TSMC’s foundry points for integration into the module.
- Samsung Electronics supplies TSMC — HBM memory (about $10.0B a year). Samsung supplies HBM where it can win qualification — still chasing Micron and SK hynix at the leading edge.
- TSMC supplies Nvidia — Finished GPU modules (about $45.0B a year). TSMC prints Nvidia’s silicon and fuses it with memory using proprietary CoWoS packaging, shipping completed $30K+ processing modules.
- TSMC supplies AMD — Chips & packaging (about $8.0B a year). TSMC fabricates AMD’s Instinct GPUs and EPYC CPUs on the same advanced nodes Nvidia uses — the two rivals share one factory.
- TSMC supplies Cerebras — Wafer-scale chips (about $1.0B a year). TSMC fabricates Cerebras’ dinner-plate-sized wafer-scale engines.
- TSMC supplies Broadcom — Chips & packaging (about $6.0B a year). TSMC fabricates Broadcom’s custom AI ASICs and networking silicon on the same advanced nodes as Nvidia and AMD.
- TSMC supplies Marvell — Chips & packaging (about $2.0B a year). TSMC fabricates Marvell’s custom ASICs and optical interconnect silicon.
- Samsung Electronics competes with TSMC — Leading-edge foundry. Samsung Foundry is the only fab even attempting to challenge TSMC at 2nm — so far with far lower yields.
- Intel competes with TSMC — 18A vs N2. The only leading-edge foundry race that matters: Intel’s 18A against TSMC’s N2, and the fight for the external customers who decide whether Intel Foundry survives.
- TSMC supplies Apple — A- & M-series silicon (about $30.0B a year). Research estimate: Apple is roughly a fifth of TSMC’s revenue and the launch customer for every leading node — the deepest supplier dependence on the map.
