UFOXADefiance Space and Connective Tech ETF

In short

MARS No data

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

MARS No data

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

MARS No data

  • 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

MARS No data

  • 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.
