Space ETFs vs Individual Space Stocks: Which Wins?

Investing in the space economy sounds simple in concept but gets complicated quickly. There are now multiple space-focused ETFs, each with different holdings and approaches. There are also individual stocks ranging from pure-play small-caps (RKLB, ASTS) to defense primes with significant space divisions (NOC, LMT). Which approach produces better risk-adjusted returns?

The answer depends on what you’re trying to accomplish — but the data is instructive.

The Space ETF Universe

UFO: Procure Space ETF

Expense ratio: 0.75% annually

AUM: ~$30-50M

Top holdings: Satellite and space communication companies globally. ViaSat, SES, Eutelsat, Iridium Communications, EchoStar, and others feature prominently.

Approach: Tracks the S-Network Space Index, focused on companies with 50%+ revenue from space activities.

ARKX: ARK Space Exploration & Innovation ETF

Expense ratio: 0.75% annually

AUM: Declined significantly from peak (peak ~$1.4B in 2021, now much lower)

Holdings: ARKX’s approach is broader — includes drone companies, 3D printing (for satellite manufacturing), and tech companies ARK believes will benefit from space innovation. Has held unusual names like Netflix (as a “space beneficiary from satellite internet”).

Approach: Active management by ARK Invest. Higher concentration and more opinionated allocation.

ROKT: SPDR S&P Kensho Final Frontiers ETF

Expense ratio: 0.45% (lower than UFO/ARKX)

Holdings: More defense-adjacent: Boeing, Northrop Grumman, Lockheed Martin, plus some purer space plays.

Approach: Tracks the Kensho Final Frontiers index — “companies whose products and services are centered on the exploration of deep space and the Earth’s oceans.”

Performance Comparison: ETFs vs. Individual Stocks

The most important data: since these ETFs launched, how have they compared to simply owning the best individual space stocks?

Note: Returns vary significantly by specific time periods chosen. This represents approximate performance ranges for illustrative purposes.

The Problem with Space ETFs

Holdings Dilution

To be diversified, space ETFs must include companies that are not your highest-conviction ideas. UFO holds companies like Eutelsat and SES — European satellite operators with declining subscriber bases and slow growth. If you’re excited about AST SpaceMobile’s growth potential, why hold it alongside declining GEO satellite companies?

The SpaceX Problem

The most valuable space company in the world — SpaceX, valued at ~$210 billion — is not publicly traded. No space ETF can own SpaceX. If you believe the space economy’s best pure play is SpaceX, you simply can’t get there through ETFs or individual stocks.

High Expense Ratios for the Category

0.75% annually for UFO and ARKX is significantly higher than the 0.03-0.07% you pay for broad market ETFs. You’re paying 10-25x more for exposure that, historically, hasn’t outperformed just owning the best individual space names.

No Concentration Where It Matters

If RKLB doubles in a year, it’s meaningful in your portfolio if you own 8% of your money in it. If RKLB doubles and it’s 3% of your UFO position (which is 5% of your portfolio), you made 0.3% on the RKLB thesis. Diversification eliminates the upside that makes individual space stock selection worth the effort.

When ETFs Make Sense

• You want basic space exposure without doing individual stock research
• Your position sizing is small enough that owning multiple individual stocks isn’t practical
• You want to avoid the volatility of individual names
• Simplicity for tax/reporting purposes matters

The Winning Approach: Focused Individual Stock Portfolio

For investors willing to do the research, a portfolio of 5-8 individual space stocks constructed with conviction produces better risk-adjusted returns than space ETFs — primarily because you can overweight your best ideas and exclude the weak ones.

A suggested framework:

• Defensive anchor (30-40%): NOC + LMT (profitable, dividends, government contracts)
• Growth core (40-50%): RKLB + PL (proven revenue, growth trajectory)
• High-upside bets (15-25%): ASTS (asymmetric, pre-revenue at scale)

This construct gives you the volatility buffer of defense primes plus the upside potential of pure-play growth companies — without the diluted exposure you get from an ETF.
