NVIDIA supply-chain v1 — executable thesis (picks-and-shovels)
First of two splits of the prior "AI-infra-chips" bucket. This thesis owns the layer of names that NVIDIA itself spends money on: foundry (TSM), advanced packaging (CoWoS / OSAT — Amkor, Powertech, Unimicron, Ibiden substrate), memory pure-plays (Micron — HBM the binding constraint), and semicap equipment (ASML lithography, AMAT / KLAC / LRCX deposition + metrology + etch). Whatever NVIDIA ships, these vendors get paid first. Sister thesis [[2026-05-18-nvidia-adjacent-v1]] owns the competitive layer (AMD, Broadcom, Intel) which competes WITH NVIDIA for the same end demand.
Why split the bucket
The prior "ai-infra-chips" frame collapsed two structurally different bets into one allocation. Supply-chain names monetize NVIDIA's revenue itself — CoWoS capacity, HBM cadence, foundry market share are the binding constraints, and the same vendors fill orders for AMD / Broadcom / hyperscaler custom ASICs too. Adjacent names monetize the alternative path — capex routed to non-NVIDIA accelerators (Google TPU, Meta MTIA, Amazon Trainium, AMD MI300/MI400, Intel Gaudi). The two baskets share macro exposure (AI capex direction) but diverge on the question "is NVIDIA's pricing power sustainable, or do hyperscaler custom-silicon programs route around it?"
Founder confirmed taxonomy 2026-05-18. Supply-chain = picks-and-shovels (vendor agnosticism to which accelerator wins); adjacent = competitive (different accelerator winners reshuffle adjacent allocation). Different exit triggers (supply-chain breaks on capacity-online cadence; adjacent breaks on customer-share signals).
The thesis (structural)
Hyperscaler AI capex hit ~$750B committed for 2026 and the binding constraints are NOT NVIDIA's design cycle — they are upstream:
CoWoS advanced-packaging capacity at TSMC. NVIDIA H100/H200/B200/B300 + AMD MI300/MI350 + Broadcom custom ASIC + Google TPU all queue for the same CoWoS-S/CoWoS-L lines. TSMC has guided multiple capacity expansions (3x in 2024, 2x in 2025, additional 2026 ramp). Every wafer of CoWoS that ships is monetized by TSM + the OSAT layer underneath (Amkor, Powertech, Unimicron substrate, Ibiden substrate).
HBM stacking (HBM3E now, HBM4 ramping Q2 2026). The 3-vendor oligopoly (Micron, SK Hynix, Samsung) has supply pre-sold through 2026 and into 2027. Every HBM wafer crowds out ~3 commodity DRAM wafers, so the tightness cascades. Micron is the only US-listed pure-play HBM beneficiary (Hynix / Samsung Korean-listed, not Alpaca-tradeable).
Litho + deposition equipment for the 3nm / 2nm / 1.4nm node migrations that gate next-gen accelerators. ASML EUV is the binding monopoly; AMAT (deposition), KLAC (metrology), LRCX (etch) are the oligopoly underneath. Capex from TSMC + Intel + Samsung foundry flows directly to these names. Tepper added LRCX 2024Q4 (later exited), Tiger Global holds LRCX in top-10 at $833M (2026Q1).
OSAT / substrate layer. Amkor (AMKR) — US-listed advanced-packaging assembly. Powertech (3036.TW), Unimicron (3037.TW), Ibiden (4062.T) — substrate suppliers underneath CoWoS. Foreign-listed names are not Alpaca-tradeable; included in thesis universe for completeness and as ADR-watch.
The thesis is "vendor-agnostic infrastructure." We are not picking which accelerator wins; we are betting that whichever accelerator wins, the same upstream suppliers get paid.
Smart-money signal scoring (across 8 tracked managers)
Per [[01-projects/investing/anchors/smart-money/2026-05-17-aggregate-2yr-backfill-summary]] + per-manager backfills:
| Ticker | Signal strength | Source | Anchor specificity | Mirror overlap? |
|---|---|---|---|---|
| TSM | 3-manager persistent | Tepper + Druckenmiller + Tiger Global top-10 for 2+ quarters (#3 Druckenmiller $167M; #5 Tepper $448M; persistent Tiger Global hold) | HIGH — direct CoWoS capacity + foundry share | YES — at 0.5R in mirror |
| MU | 1-manager high-conviction | Tepper #2 position 2026Q1 at $562M (+106% in 2025Q2 to $101M, then ramped to $562M by 2026Q1) | HIGH — HBM3E shipping, HBM4 Q2 2026 ramp, supply pre-sold 2026 | NO |
| LRCX | 1-manager + 2-manager historic | Tiger Global top-10 #10 at $833M in 2026Q1; 2024Q4 NEW from Tepper + Tiger (both later exited); re-entered by Tiger | MEDIUM — etch equipment to all foundries; cyclical | NO |
| AMAT | weak/historic | Tiger Global NEW 2024Q2; not in 2026Q1 visible top-10 | MEDIUM — deposition to all foundries | NO |
| ASML | weak/historic | Tepper +106% in 2024Q4 (to $110M, sub-top-10); no recent | HIGH — EUV monopoly | NO |
| KLAC | none in tracked managers' top-10 | — | MEDIUM | NO |
| AMKR | none in tracked managers' top-10 | — | HIGH — direct CoWoS-adjacent OSAT | NO |
| 3036.TW / 3037.TW / 4062.T | not visible (foreign filings) | — | HIGH — substrate supply | NO; also not Alpaca-tradeable |
Names that don't earn a slot
- KLAC — fundamental case is fine but no smart-money corroboration in the 8-manager scan AND already get partial exposure via LRCX/AMAT cohort. Cut.
- AMAT — single historic Tiger NEW (2024Q2), no current top-10, no anchor specificity beyond LRCX. Cut as redundant with LRCX in the etch/deposition slot.
- ASML — strongest fundamental anchor (EUV monopoly) but smart-money signal is single-manager historic, not current. Hold as watchlist; don't deploy in v1.
- AMKR — clean US-listed CoWoS-adjacent name but zero smart-money corroboration and gross margins are thin OSAT-style (10-15%). Hold as watchlist.
- Foreign-listed substrate (3036 / 3037 / 4062) — Alpaca paper sandbox doesn't trade these. Documented in the universe for the eventual brokerage-expansion conversation; zero deployment in v1.
Position sizing (R-unit, v1)
Per parent README: 1R = $5,000. Bucket cap = 4R ($20k). The R-weight reflects signal-strength + anchor-specificity + duplicate-coverage adjustment.
Initial deploy (paper)
| Ticker | R | $ | Why this weight | Mirror overlap adjustment |
|---|---|---|---|---|
| MU | 1.5R | $7,500 | Strongest single-name fundamental anchor (HBM supply pre-sold through 2026, +106% YoY revenue Q2-fiscal-2026, only US-listed HBM pure-play). Tepper sized to #2 position at $562M = his strongest semis-conviction. No mirror overlap → full weight. | None |
| TSM | 0.5R | $2,500 | 3-manager persistent (the highest smart-money corroboration of any chip name). But ALREADY in smart-money-mirror at 0.5R → this is an INCREMENTAL 0.5R on top, bringing total TSM exposure to 1.0R across both strategies. Acknowledged double-count: each strategy tracks separately, founder needs to be aware net TSM = 1.0R combined. | DOUBLE-COUNTED — net exposure 1.0R |
| LRCX | 0.5R | $2,500 | Tiger Global top-10 at $833M (2026Q1); cyclical semicap exposure adds different shape from foundry/memory pure-plays. Single-manager so sized at half of MU. | None |
| Cash reserve | 1.5R | $7,500 | Held for (a) ASML / AMKR add if smart-money signal lights up in Q2/Q3 2026 13F, (b) anchor-strength add to MU on >20% drawdown with bullish anchors per Druckenmiller doctrine, (c) AMKR if CoWoS-shortage news cycle materializes | — |
| Total deployed | 2.5R | $12,500 | ||
| Bucket cap | 4R | $20,000 |
Korean primaries explicitly excluded
Samsung (005930.KS) and SK Hynix (000660.KS) are excluded from v1 due to Alpaca paper-sandbox tradeability. They ARE the largest HBM beneficiaries by absolute output and would belong in this basket if our brokerage supported them. Re-evaluate when brokerage expands.
Druckenmiller doctrine (same as memory v1.1 + power v1.1)
- No mechanical price-based stops. Drawdowns are NOT exit triggers. Drawdowns with bullish anchors are BUYING signals (anchor-strength add per cash reserve, +0.5R per name up to 3R cap).
- Tranche entry permitted. Initial 0.5R per name; add 0.5R on -5% from t1 avg with thesis-confirming catalyst; add 1R on -10% from t1 avg with earnings catalyst (per memory v1.1 template).
- Exit triggers are fundamental, not price-based:
| Trigger | Severity | Action on first signal | Action on confirmation |
|---|---|---|---|
| TSMC CoWoS capacity expansion announcement materially exceeds projected demand (cycle-peak signal) | High | Founder review via /decisions/ | Close ENTIRE bucket |
| HBM capacity-online cadence catches/exceeds hyperscaler capex (the "memory thesis" broke) | High | Founder review | Close ENTIRE bucket |
| Hyperscaler combined capex revised DOWN >10% across 2+ consecutive quarters | High | Founder review | Close ENTIRE bucket |
| 2+ tracked smart-money managers EXIT same supply-chain name same quarter | Medium | Founder review | Trim affected name to 0.5R |
| Major foundry / memory vendor signals 2027 capex cut | Medium | Founder review | Trim to 0.5R |
| CXMT or YMTC achieves volume HBM3E-equivalent production | Medium | Founder review | Trim MU specifically |
| Single hyperscaler announces in-house foundry / packaging strategy that bypasses TSMC | Medium | Founder review | Trim TSM specifically |
| Founder kill-switch (channel: "halt supply-chain" / "pause investing") | n/a | Close immediately | n/a |
Single signal of any severity = Ray surfaces via /decisions/ within 7 days. No autonomous exit on a single anchor flip.
Lightweight backtest read (5-min sanity check)
Did NVDA supply-chain names track NVDA's 2023-2026 ramp?
Yes, clearly. TSM appreciated ~3x from early 2023 ($75 area) to 2026Q1 ($200+) — directly tracking NVDA's ~10x in the same window, with the natural derating because supply-chain captures margin-with-a-lag and isn't the design-IP layer. MU returned 2.5x from the 2022 cyclical bottom ($50) to 2026 ($120+) driven specifically by HBM3E mix-shift in 2024-2025. LRCX returned ~2x from 2023 lows tracking foundry capex. The supply-chain didn't capture NVDA's pricing-power premium (NVDA gross margins 75%+ vs TSM 55% vs MU 35-40%) but it absolutely tracked the ramp directionally. The thesis is empirically the right shape for the past cycle.
Honest caveat: 2023-2026 is a single cycle, and this is a sanity check not a backtest. A full multi-cycle backtest of "supply-chain follows leading-edge accelerator" would need to backstop into 2017-2018 (NVDA Pascal/Volta cycle) and 2020-2021 (Ampere). Defer to next backtest cycle.
Overlap with smart-money-mirror v1 (explicit)
TSM is the only direct overlap. Mirror has TSM at 0.5R; supply-chain v1 has TSM at 0.5R; net TSM exposure across both strategies = 1.0R = $5,000.
This is intentional double-counting:
- The mirror layer says "3 positive-sum managers persistently hold TSM in top-10, so we follow."
- The thesis layer says "TSM is the binding-constraint vendor for the picks-and-shovels argument; sizing reflects fundamental anchor specificity."
- Both signals are independently valid; doubling the exposure reflects that the structural argument is corroborated by smart-money positioning.
Position-tracking stays distinct per strategy (smart-money-mirror-v1 logs TSM separately from nvidia-supply-chain-v1 logs). Founder needs to know that total notional in TSM is 2x what each ledger shows individually.
Decision point for founder: is 1.0R = $5k net exposure to TSM acceptable, or should the supply-chain v1 layer reduce TSM to 0.25R (net 0.75R) to free up R for AMKR or ASML adds?
Cross-domain translation
Shape here is upstream-supplier capture of a downstream pricing-power cycle. Same shape as: oil-services (Halliburton / Schlumberger) when E&P capex booms — the picks-and-shovels names monetize the cycle without taking the discovery-risk that the operator names take. Or: SaaS-vendor capture of the 2018-2022 cloud-native build-out — Datadog/Snowflake/Confluent grew alongside AWS without competing with AWS. The NVIDIA supply-chain thesis applies the same template: TSM/MU/LRCX/AMKR monetize NVIDIA's hyperscaler-capex windfall without taking the design-IP risk that NVIDIA itself takes.
In data-engineering analogy: this is the dbt-vendor bet on the modern-data-stack cycle — pick the workflow surface every operator passes through, not the operator itself. TSM is dbt for the AI-chip stack; whichever accelerator wins, the workflow passes through TSM's fabs.
Disqualifying conditions (thesis-archive triggers)
Two-or-more of the HIGH severity exit triggers confirmed across 1-2 quarters = thesis archived, bucket closed, post-mortem filed. Specifically: any of (CoWoS oversupply, HBM cadence catches demand, hyperscaler capex DOWN >10% for 2Q) firing together = full bucket exit.
Phase markers (informational, not exit triggers)
| Phase | Definition | Position posture |
|---|---|---|
| Phase 1 — Tight upstream, demand outrunning capacity (current) | TSMC CoWoS sold out, HBM pre-sold, hyperscaler capex flat-or-up | Initial 2.5R deploy + cash reserve for anchor-strength adds |
| Phase 2 — Capacity expansions announced but not yet online | Material CoWoS or HBM capacity expansion in the pipeline | Hold; consider trim if expansion materially exceeds projected demand |
| Phase 3 — Capacity online catches/exceeds demand | Cycle peak signal — supply chain margins compress | Close per disqualifying-condition logic |
Caveats / open risks
- N=1 sanity check, not a backtest. Supply-chain-follows-leading-edge thesis empirically held through 2023-2026 but that's a single cycle. Multi-cycle backtest deferred.
- MU concentration (1.5R = 37.5% of bucket). Single-name drawdown risk is material. Acceptable in paper given anchor specificity; revisit before live-capital migration.
- TSM geopolitical tail. Taiwan-strait risk is a binary fundamental-anchor-break that mechanical analysis cannot price. The 0.5R supply-chain layer + 0.5R mirror layer = 1.0R total TSM exposure is the bucket's largest single-stock geopolitical exposure.
- CoWoS competitor risk. Samsung and Intel Foundry both want CoWoS-equivalent capacity. If one of them comes online materially faster than expected, TSM's pricing power on advanced packaging compresses. Watch capex commentary on both 2026 earnings calls.
- Korean primaries (Hynix / Samsung) absent from basket. These are the largest HBM beneficiaries in absolute terms. MU alone is the US-listed proxy and captures less than 25% of global HBM output. The thesis is genuinely under-expressed by US-listed names only.
- Smart-money signal on LRCX is single-manager. Tiger Global is the only persistent holder. If Tiger exits in Q2/Q3 13F, LRCX trims to 0.25R per the exit-trigger table.
