A $100 Nuclear Portfolio Allocation Blueprint

Getting exposure to the nuclear value chain is one thing; deciding how much to put in each tier is the harder part. The names are many, and each tier has its own cycle sensitivity and margin structure. Here's how I'd think about splitting $100, starting from scratch.

1. $50 to operating utilities — the anchor

Half the basket goes to Tier 4 (operating utilities). It's the biggest slice for a simple reason: highest conviction.

These companies have already signed the long-term PPAs. Electricity prices are rising everywhere, and when the merit-order mechanism pushes wholesale up, revenue and margin follow automatically. The mechanism that prints money when gas spikes lives in this tier.

This is where Constellation (CEG) with its 22-reactor fleet, Vistra with the Meta 2.6GW deal, and Talen with the Amazon 1.9GW anchor sit. If Talen's litigation risk feels heavy, you can lean into CEG and Vistra instead.

2. $25 to the fuel cycle — the leverage

Next biggest slice: Tier 2 at $25. This is where you grab the most leverage at the moment demand finally outruns supply for the first time in a decade.

The way I see it, if you control the fuel, you control the speed of the entire rollout. Centrus Energy is the only US enrichment provider, with backlog up from effectively zero to $2B+ in two years. BWXT is the two-front exposure — equipment plus TRISO fuel.

You can split this $25 evenly between Centrus and BWXT, or tilt 60/40 toward BWXT for slightly steadier earnings.

3. $15 to mining — the foundation

Tier 1 gets $15. Mining is the source of everything. If uranium doesn't come out of the ground, every tier above stalls.

Cameco is the core position — for the combined 14–20% mining share plus the 49% Westinghouse stake. If you can only pick one Tier 1 name, it's Cameco. If you want more dispersion, mix in small slices of Energy Fuels (rare earth optionality), UEC (largest US producer), Paladin (Namibia), and Denison (higher-grade Canadian).

4. $10 to innovation reactors — the moonshots

Tier 3 gets the last $10. This is where potential millionaires get made — if Oklo, NuScale, or X-energy hits big, it can lift the whole portfolio.

But if none of them hits, Tiers 1, 2, and 4 carry the entire investment. That's why $10 is the cap here. The core exposure lives elsewhere; this slice is option value.

5. Adjusting for risk tolerance

Not everyone has the same time horizon or risk appetite. You can shift weights:

• Conservative (utility-heavy): Tier 4: 60, Tier 2: 25, Tier 1: 10, Tier 3: 5. Steadiest cash flow.
• Standard (the 50/25/15/10 above): Balanced. Fits most investors.
• Aggressive (Tier 3 lean): Tier 4: 40, Tier 2: 25, Tier 1: 15, Tier 3: 20. When you want more option value on the advanced reactor wave.

6. Simplifying with ETFs

If picking individual stocks isn't your style, ETFs cover the same ground. URA, URNM, and NLR are the main uranium and nuclear ETFs — they bundle mining through operations and rebalance for you. The trade-off: ETFs assign their own weights across tiers, so if you specifically want a utility-heavy book, layering individual operators on top of an ETF is one workaround.

FAQ

Q: Is this a 3-month trade? A: No. It's a 5-to-10-year setup. The grid doesn't get built overnight. Supply constraints hit first, demand follows, and the companies that own the leverage in between print over the cycle.

Q: What's the biggest risk? A: Grid connection delays (like Three Mile Island slipping 4 years) and single-name litigation (Talen, NuScale). The first line of defense is not concentrating Tier 4 in one name.

Q: Can I oversize Tier 3? A: Depends on your risk appetite. If SMRs get deployed at scale in 10 years, Tier 3 returns could explode — but in the meantime certification delays and funding risks compound. I'd only push above 20% if the rest of your portfolio is genuinely stable.

Q: Is it too late to enter? A: For round one, yes — CEG is 5x and Talen is 10x already. But the $200B in PPAs is just starting to enter the revenue recognition phase, and the margin expansion from the merit-order mechanism hasn't really kicked in yet. Round two is still on the table.
