Portfolio Construction Overview
How the 27 holdings are assembled into a coherent portfolio. Read after The AI Value Chain. Companion notes: Core vs Satellite Holdings, Return Drivers vs Hedges, Overlap & Diversification Map, Position Sizing Framework.
The Construction Philosophy#
PCA SOF is built as a value-chain-complete, concentrated, barbelled thematic portfolio. Three principles govern it:
- Completeness over selection. Rather than bet on the single AI winner, own every layer of The AI Value Chain so the fund captures value wherever it migrates.
- Concentration with role-clarity. ~27 names, each with a defined role. No holding exists without a job.
- Barbell the risk. Capital-intensive cyclical compounders (memory, foundry, power) on one end; capital-light secular software + a non-AI diversifier ring on the other.
The Three Construction Rings#
RING 1: THE AI INFRASTRUCTURE SPINE (the return engine, highest weight)
NVIDIA · TSMC · Micron · Marvell · Disco · Constellation · Vistra
+ the hyperscalers: Microsoft · Amazon · Alphabet · Meta
→ highly correlated; share a RISK BUDGET (see Overlap & Diversification Map)
RING 2: THE AI SOFTWARE / MONETISATION LAYER (quality compounders)
ServiceNow · Salesforce · Snowflake · Datadog · CrowdStrike · Zscaler
→ monetise AI in the enterprise; lower capex-cyclicality than Ring 1
RING 3: THE DIVERSIFYING SECULAR RING (the shock absorber, lower correlation)
Payments: Adyen · PayPal
EM internet: Tencent · MercadoLibre
China consumer: Li Ning | EV: BYD
Media: Netflix · Roblox | Healthcare: BioNTech · IQVIA
→ independent drivers; dampen AI-capex beta
The genius of the construction: Ring 1 is the torque, Ring 3 is the ballast, Ring 2 bridges them.
How Weighting Works (inferred)#
Weights follow the conviction-and-role logic of Position Sizing Framework:
- Largest weights → Ring 1 chokepoints with the clearest AI leverage + deepest moats: Micron, NVIDIA, TSMC at/near the top (per the stated holdings order), plus the mega-cap hyperscalers.
- Mid weights → Ring 2 software compounders + the power names (Constellation, Vistra) + Marvell.
- Smaller weights → Ring 3 diversifiers + higher-variance satellites (Roblox, BioNTech, Li Ning, Disco).
The stated holdings order (Micron → NVIDIA → TSMC → Alphabet → Datadog → … → BYD) broadly tracks descending weight, confirming an AI-infrastructure-led book with a long diversifying tail.
Why The Portfolio Is Built This Way, Answering The Key Questions#
| Question | Answer | |, -|, -| | Which are core holdings? | The AI infrastructure spine + hyperscalers (Ring 1). → Core vs Satellite Holdings | | Which are satellites? | Ring 3 diversifiers + higher-variance names (Roblox, BioNTech, Li Ning, Disco, Snowflake). | | Which drive returns? | NVIDIA, TSMC, Micron, the hyperscalers, the power names, Ring 1. → Return Drivers vs Hedges | | Which hedge risks? | The Ring 3 diversifiers (payments, EM, healthcare, EV, media). | | Which overlap? | The entire AI spine is correlated, a managed risk budget. → Overlap & Diversification Map | | Which diversify? | Geography (TSMC, Tencent, BYD, MELI, Adyen, BioNTech, Disco, Li Ning) + theme (payments, healthcare, EV). |
The Barbell, Explicitly#
- Cyclical-compounder end: Micron Technology, TSMC, Disco Corporation, Constellation Energy, Vistra, capital-intensive, cyclical inside a secular uptrend; sized for amplitude, added into weakness.
- Secular-steady end: Microsoft, ServiceNow, Adyen, Datadog, CrowdStrike, capital-light, recurring revenue, lower amplitude.
- Asymmetric-optionality corner: BioNTech, Roblox, call-option payoff profiles.
What Could Go Wrong With The Construction#
The honest critique: Ring 1 + much of Ring 2 share one factor, AI capex. If hyperscaler spend pauses, ~15+ holdings fall together regardless of their layer. The fund's only true diversification is Ring 3 + the geographic spread. This is the central risk the construction manages but cannot eliminate, see Overlap & Diversification Map + AI Capex Cycle Risk + Risk Master Note.
