NUKZ vs SMRF

NUKZCRange Nuclear Renaissance Index ETF

SMRFBALPS Nautilus SMR, Nuclear & Technology ETF

In short

NUKZ A 2024-vintage, rules-based take on the nuclear buildout: one purpose-built index covering the uranium-and-reactor theme in a plain equity ETF. It prices above the category median, but its portfolio build sits in the upper half of the pack.

SMRF Nuclear power meets option-writing. SMRF actively holds about 70 global small-modular-reactor, nuclear and related tech names, then buys and writes options on top to pull income from a famously jumpy theme.

Stated mandate

NUKZ The fund seeks to track, before fees and expenses, the total return of the Range Nuclear Renaissance Index.

SMRF The Fund seeks capital appreciation and income through an actively managed portfolio of equity securities significantly tied to the Nautilus SMR, Nuclear & Technology Index, together with bought and written options.

Why people hold it

• NUKZ Pure index mechanics. It tracks the Range Nuclear Renaissance Index before fees and expenses, so holdings follow published rules rather than a manager's discretion.
• Portfolio construction and risk profile both land in the upper half of the uranium and nuclear cohort, the sturdier side of a famously jumpy category.
• Straightforward plumbing: stocks in a standard 1940 Act fund wrapper, not a physical uranium trust or a futures structure.
• Live since January 2024 and now carries real assets with steady day-to-day volume, not the thin tape many thematic launches never grow out of.

• SMRF Charges 0.65% a year, under the median for its options-income peer group and below names like HYGW (0.69%) and SVOL (0.66%).
• One wrapper, two jobs: the fund seeks capital appreciation and income, pairing the stock sleeve with bought and written options.
• Actively managed around the Nautilus SMR, Nuclear & Technology Index rather than bolted to it, so the manager sets the option book.
• Spreads across roughly 70 global holdings instead of a handful of pure-play reactor startups, and the income policy targets a relatively stable payout level.

Worth knowing

• NUKZ It charges 0.85% a year, above the median for nuclear and uranium funds and well above the cheapest peer in the group, NLR at 0.52%.
• One theme, one corner of energy, and a 2024 start date. There is no long record here across a full market cycle.
• Distributions arrive once or twice a year. This is built as a thematic equity holding, not an income stream.

• SMRF Written calls trade away part of a big rally for premium today. In a runaway nuclear melt-up, the option book is the brake.
• Launched in 2026 with a small asset base and thin trading, so spreads can run wider than in the giants of the category.
• A single-theme portfolio tied to reactors, uranium and power-hungry tech moves on policy and project news, and swings harder than a broad index.
