ROKTAState Street SPDR S&P Kensho Final Frontiers ETF

UFOXADefiance Space and Connective Tech ETF

In short

ROKT Most space funds stop at the atmosphere. ROKT plays both frontiers: rockets and satellites plus the hardware that explores the deep sea, wrapped in an AI-informed S&P Kensho index running since 2018.

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

ROKT The fund seeks to track the S&P Kensho Final Frontiers Index, targeting companies whose products and services support innovation in outer-space and deep-sea exploration through an AI-informed, quantitative index methodology.

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

  • ROKT 0.45% a year, the cheapest sticker in this cohort: ORBX runs 0.50%, while UFO, ARKX and NASA each charge 0.75%.
  • The index bolts the S&P Kensho Space Index onto the deep-sea exploration names from the Kensho Drones Index, so orbit and ocean floor arrive in one ticker.ssga.com
  • Trading since 2018 under the SPDR roof, and one of the strongest implementations in the space-theme group on cost, portfolio and staying power.
  • Roughly 40 stocks, refreshed on the index's annual reconstitution, with cash paid quarterly.ssga.com
  • 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

  • ROKT Trades lightly next to mainstream ETFs and carries a modest asset base; wider bid-ask spreads are the usual trade-off at that size.
  • Two frontiers in roughly 40 names is a concentrated slice of the market that can move very differently from a broad index.
  • The deep-sea sleeve means this is not a pure space bet: part of the portfolio never leaves the water.ssga.com
  • 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.
