Our read on each fund

ETF.net Research

NASACTema Space Innovators ETF

UFOXADefiance Space and Connective Tech ETF

In short

NASA It landed the ticker every space fund wanted. NASA is a concentrated, roughly 40-stock read on the space economy, from defense systems to space tourism, and it trades like a much older fund.

UFOX A space theme without the space-theme price tag. UFOX tracks a rules-based index of roughly 60 satellite and connectivity companies for 0.30%, a little over half what the typical global thematic fund charges.

Stated mandate

NASA The Fund seeks long-term growth through investments connected with space-related innovation, including areas such as defense systems and space tourism.

UFOX The fund seeks to track, before fees and expenses, the total return of the BlueStar® Space and Connective Technologies Index. It uses passive indexing and generally invests in the index constituents.

Why people hold it

NASA One ticker, the whole launchpad: about 40 names tied to space innovation, spanning defense systems through space tourism.
Charges 0.75% a year, right at the median for space ETFs, so the concentrated active approach costs no more than the category norm.
Very actively traded and already north of a billion in assets, so getting in and out is rarely the hard part.
Lands in the upper half of its space-fund peer group on our overall read, helped by how cleanly it trades.

UFOX Charges 0.30% a year, against a 0.56% median for its global thematic peers. Niche themes usually cost more, not less.
Fully rules-based. It tracks the BlueStar Space and Connective Technologies Index, so what lands in the portfolio follows a published methodology, not a manager's hunch.defianceetfs.com
About 60 holdings across a global and US mandate, so the theme is spread over satellite and connectivity businesses rather than three or four pure plays.
Listed since 2019, mid-sized, moderately traded and paying quarterly. On the whole, one of the stronger profiles in its global thematic group.

Worth knowing

NASA Cheaper orbits exist: ROKT charges 0.45% and ORBX 0.50%, against 0.75% here.
A 2026 launch with about 40 holdings in a story-driven sector: thin history to judge, and single names carry real weight.
Built for long-term growth, not income. It has not paid a distribution.

UFOX One theme, roughly 60 stocks. Space and connectivity names tend to move together, so the ride is bumpier than a broad market fund.
Wide tent. "Space and connective technologies" stretches from satellites to connectivity infrastructure, so check the holdings list to see what you actually own.defianceetfs.com
Cheap for a theme fund, not cheap outright. Broader global peers such as KLMT (0.10%) and IQSZ (0.19%) sit well below it on fees.
