Two-Bucket Model (2025)

Bucket 1: Pure-Play Upside (high beta, tech leaders)

• IonQ (IONQ): ~3–4% allocation
  Catalyst: Next logical-qubit demo, enterprise adoption updates.

• CCCX → INFQ (Infleqtion): ~2–3% allocation
  Catalyst: PIPE close, SEC S-4 effectiveness, shareholder vote, SPAC redemptions, first Tiqker atomic clock shipments.

• Rigetti (RGTI): ~2% allocation
  Catalyst: New government contracts, roadmap to multi-chip modules, progress on gate fidelity.

Total pure-play allocation: ~7–9% of portfolio.

Total diversified allocation: ~6–9% of portfolio.

---

Key Catalysts to Track

• PIPE close & S-4 effectiveness (CCCX/INFQ) → first confirmation of SPAC funding strength.

• Shareholder vote & redemption window → determines actual cash on Infleqtion’s balance sheet.

• First Tiqker customer shipments → validates earlier revenue via sensing products.

• Next logical-qubit demo (IonQ, Quantinuum, IBM) → milestone toward error-corrected workloads.

• Government contracts/defense programs (Rigetti, Infleqtion, IBM) → recurring revenue signals.

📊 Tiered Portfolio Allocation for Quantum Technologies (2025–2030)

1. Balanced Strategy (risk-adjusted, diversified)

• Core (40–45%)

  • Superconducting (IBM, Rigetti, Alphabet)

  • Trapped Ions (IonQ)

  • Rationale: These platforms have the most technical readiness, large-cap support, and steady roadmaps. They anchor the portfolio.

• Speculative (20–25%)

  • Neutral Atoms (Infleqtion → INFQ)

  • Photons (PsiQuantum, Xanadu)

  • Rationale: High-growth, high-risk platforms that could leapfrog, but funding cycles and technical hurdles are non-trivial. Position sizing smaller keeps risk in check.

• Enablers (25–30%)

  • Particle Spins (Intel, GlobalFoundries)

  • Rationale: Semiconductor-synergy “picks and shovels” angle, giving steadier returns and exposure to ecosystem build-out.

• Moonshot (5–10%)

  • Quasiparticles (Microsoft’s topological R&D)

  • Rationale: Tiny allocation for the optionality of a breakthrough in Majorana/topological qubits.

---

2. Aggressive Strategy (growth-maximized, higher beta)

• Core (30–35%)

  • Still anchor with superconducting + ions (IBM, Rigetti, IonQ).

• Speculative (35–40%)

  • Lean heavily into Neutral Atoms (Infleqtion/INFQ) and Photonics (PsiQuantum, Xanadu) given their scale/revenue catalysts.

• Enablers (20–25%)

  • Intel + GFS remain in the mix, but lower weight relative to balanced.

• Moonshot (10%)

  • Keep a higher-than-usual bet on quasiparticles — since in a high-risk posture, a tail-event breakthrough could be transformative.

---

✅ Key takeaway:

• The balanced strategy emphasizes survivability and long-term compounding, anchored by superconducting/ions + semiconductor enablers.

• The aggressive strategy emphasizes speculative platforms (Infleqtion’s neutral atoms, photonic plays) where valuations could swing most sharply.

---

Summary:

• Pure-play upside (IONQ, INFQ, RGTI) offers high growth but high volatility; size positions cautiously.

• Diversified enablers (IBM, GFS, large-cap tech) provide stability, supply-chain leverage, and broader AI/quantum synergies.

• Watch catalysts closely: successful Infleqtion de-SPAC, logical-qubit demos, and early product shipments could trigger reratings across the sector.

📈 Investor Takeaways

• NVEC:

  • Best for retail investors wanting direct spintronics exposure, with income stability (6% dividend yield).

  • Niche focus makes it volatile but differentiated.

• GFS:

  • Best for exposure to spintronics at scale (eMRAM in auto/IoT chips), backed by government support.

  • A strategic, lower-risk play on spintronics integration into mainstream semis.

Combined Strategy

• Why own both?

  • NVEC = “pure physics boutique” → dividend income + niche exposure.

  • GFS = “infrastructure backbone” → large-cap stability + scaling of MRAM into auto/IoT.

  • Together, they give retail investors broad yet complementary exposure to spintronics’ present (NVEC) and future (GFS).

✅ Bottom line:
For a retail investor bullish on spintronics and quantum-adjacent tech, a mini-portfolio of NVEC + GFS blends direct spintronics exposure with foundry-scale adoption. Add Everspin (MRAM) if you want higher-risk, higher-reward pure MRAM growth.
