Nuclear as the scarce clean-firm answer to AI power demand: hyperscaler PPAs and restarts repricing the operating fleet, SMR developers racing to first concrete, and a fuel cycle being onshored after decades of Russian dependence. Overlap with power-grid is deliberate — this basket isolates the nuclear-specific leg: merchant fleet operators, reactor OEMs, enrichment and uranium, and instrumentation.
Follow the theme against the wider market.

1y · 2025-10-16 – 2026-10-16 · 252 / 252 sessions
Basket total returns · Annualized using 252 trading sessions · 0% risk-free rate and downside target. As of 2026-10-16 · close.
Sharpe: average daily simple return divided by its sample standard deviation, multiplied by √252. The risk-free rate is assumed to be 0%; this is not a cash-adjusted ratio.
Sortino: average daily simple return divided by downside deviation, multiplied by √252. Downside deviation is the square root of the average squared shortfall below 0%, counting all sessions, including zeros for gains.
Historical volatility: √(252 × average squared daily log return), matching the Vol page’s realized-volatility convention. This differs from the sample standard deviation used in Sharpe.
Each period requires complete history and at least 5 sessions. MTD and YTD follow the calendar; 1y is 252 sessions. Missing data or an undefined ratio displays — with a reason. Short periods can produce unstable ratios; intraday snapshots include a partial session. History before this basket’s creation is backtested. If a new basket has no stored daily return series yet, estimates from its rounded published chart levels are marked ≈.

Cross-checked against NLR. Daily return correlation: 0.82 across 1707 sessions. operators, OEMs and fuel in one fund; includes foreign listings (Cameco, Kepco) outside our US-only universes
Initial composition: 13 names — merchant fleets (CEG, VST, TLN, plus PEG as the nuclear-concentrated regulated exception), OEM and developers (GEV, BWXT, OKLO, SMR, NNE), fuel cycle (LEU, UEC, UUUU) and instrumentation (MIR). Reference pinned to NLR. Considered and excluded: CCJ and the foreign fuel majors (non-US-domiciled, outside the FW 3000), the private developers everyone actually watches (X-energy, TerraPower, Kairos, Westinghouse), regulated utilities with fleets buried in rate base (D, DUK, SO, ETR — no merchant leverage to nuclear scarcity), and pre-revenue fuel tech (LTBR, ASPI — NNE already carries the speculative leg).
