What this ETF tracks

UFO is a passive index ETF that tracks the S-Network Space Index (SPACE), a modified capitalization-weighted, free-float- and space-revenue-percentage-adjusted equity index developed by S-Network Global Indexes. The "space revenue percentage adjustment" is the design choice that matters: each constituent's weight is scaled down if less than 100% of its revenue comes from space. So Sirius XM (satellite radio, ~4.5% weight) sits in the index because its revenue is technically satellite-delivered, but it does not dominate the way a naive market-cap weighting would suggest. The index reconstitutes and rebalances semi-annually, with a quarterly float-share adjustment for changes greater than 5%.

The "pure-play" rule is the load-bearing piece: at least 80% of index weight must sit in companies that derive a majority of annual revenue from space-related activities — and in practice "majority" usually means 100%. That gives UFO a structurally cleaner exposure than ITA (which is dominated by aerospace primes whose space exposure is a single-digit fraction of revenue), and a broader exposure than ARKX (which is active and concentrated, with the manager picking 33 names instead of 54). The S-Network index also runs a "Fast-Track Inclusion" rule that lets the index add newly public space companies without waiting through traditional waiting periods — designed explicitly so that a Starlink IPO, a Voyager, or an Axiom Space could enter the index within days of listing rather than at the next semi-annual rebalance. That fast-track rule is the single biggest reason UFO is the institutional default hedge: any new-issue catalyst gets reflected mechanically.

The ETF is run by ProcureAM, structured under the Procure ETF Trust II. NASDAQ-listed. Launched April 2019. As of mid-May 2026 it holds 54 names with top-10 concentration at 49.55%.

Index methodology / rebalance

Semi-annual reconstitution in mid-June and mid-December — these are the dates that matter for any inclusion/exclusion trade. The June 2026 rebalance is the next binary; with the Fast-Track rule active, a Starlink listing (rumored Q3 2026) could trigger an off-cycle inclusion. Float-share adjustments quarterly if any constituent's float moves more than 5%.

Cap-weighted at the index level but the space-revenue-percentage adjustment functions as a soft cap on non-pure-play names. There is no hard single-name cap inside UFO the way ITA caps at 22.5%, but in practice the largest position has been bounded in the 6-8% range by the revenue adjustment. The fund uses full replication rather than sampling, so tracking error is structurally low — historically inside 5 bps annualized excluding fees.

Notable structural quirk: UFO holds international space names (MDA Space, the Canadian satellite company, currently 4.71%) without an ADR wrapper, taking on FX exposure directly. That makes UFO a slightly broader-than-US bet relative to ARKX (88.8% US) and ITA (effectively 100% US).

AUM, expense ratio, daily volume

AUM sits at approximately $889M as of May 18, 2026 — up from roughly $745M six days earlier, a 19% AUM jump driven by both performance and inflows. That's a critical liquidity threshold; below $500M UFO trades with materially wider spreads and creation/redemption is sluggish. Expense ratio is 0.75% (75 bps) — the same as ARKX and NASA, materially higher than ITA's 0.40%. Average daily volume is now in the 250-400K share range, up from sub-100K in 2023. The fund pays a small distribution (quarterly) — yield ~0.4%, immaterial.

Bid-ask spread typically 5-8 bps intraday. Premium/discount to NAV stays inside ±10 bps in normal tape, can widen to 30-40 bps during melt-ups (today is one of those days). Use limit orders.

Top 10 holdings + concentration

Top 10 as of May 18, 2026: Rocket Lab (RKLB) 7.37%, Planet Labs (PL) 6.41%, ViaSat (VSAT) 5.91%, EchoStar (SATS) 4.86%, Globalstar (GSAT) 4.84%, MDA Space (MDA) 4.71%, Iridium (IRDM) 4.62%, Firefly Aerospace (FLY) 4.54%, SiriusXM (SIRI) 4.51%, Intuitive Machines (LUNR) 4.23%. Top 10 = 49.55% of fund. The other 44 names split the remaining 50.45%, which keeps the long tail meaningful — UFO is genuinely diversified across the universe in a way ARKX is not.

The composition tells you the tradeoff: RKLB, PL, FLY, LUNR are the high-beta new-space names you actually want (combined ~22.6% of fund). VSAT, GSAT, IRDM, SIRI are the legacy satcom drag (combined ~19.9%). MDA and SATS are the in-between. So you're paying for the new-space exposure but eating the legacy weight as a tax — that's the structural compromise of going passive.

What's happening at largest holding (RKLB)

Rocket Lab at 7.37% is the fund's largest single exposure, up from ~5% at the start of 2026 — driven by RKLB's parabolic run (now $137.47, +37% above its 50MA, RSI 69.3, scanner flagged EXIT_WARN). That means UFO's near-term beta is increasingly a derivative of one name. If RKLB rolls over from these levels, UFO loses ~8% of its weight to whatever drawdown RKLB takes. RKLB next catalyst is Q2 2026 earnings (early August, exact date TBC) and the first commercial Neutron flight, currently scheduled for late Q3 2026. Both binary events flow through UFO at full weight until the next semi-annual rebalance trims them.

The deeper read: RKLB went from 5% → 7.37% inside six months because the space-revenue-percentage adjustment doesn't reweight intra-period — only at rebalance. So UFO is currently more concentrated in RKLB than its methodology intends.

Alternative ETFs: UFO vs ARKX vs NASA vs ITA — when to use which

UFO is the right choice when you want broad passive exposure to the full space universe and you trust index discipline to handle re-weighting. It captures both pure-plays (RKLB, PL, FLY) and the satcom legacy tail (IRDM, VSAT, SIRI). Cheapest beta to "space melt-up" as a single ticker — but you eat ~20% legacy-satcom drag.

ARKX is the right choice when you want active management and don't mind paying for stockpicking risk. Ark concentrates (top 10 = 57%, only 33 names), tilts heavily toward defense crossover (LHX 9.6%, KTOS 7.8%), and explicitly chases the "innovation" thesis. Best when you trust Cathie Wood's team to rotate as the cycle matures — worst when you don't, since fees are the same as UFO but turnover is higher.

NASA is the right choice when you specifically want SpaceX exposure inside an ETF wrapper. It holds 89,771 SpaceX share-equivalents worth ~$59M (implying a ~$1.56T SpaceX mark) and that single position is the structural alpha — no other listed ETF gives you SpaceX directly today. Newer (launched 2024), smaller ($333M AUM), narrower (20-40 names), and you take some private-mark NAV opacity in exchange for pre-IPO optionality.

ITA is NOT a space ETF. It's an aerospace and defense ETF where the top 4 (GE Aerospace 19%, RTX 14.7%, BA 10%, HII ~5%) account for ~50% of the fund and the space exposure is reduced to RKLB at 5.12% plus a smattering of crossover names. Use ITA only when you want defense-prime exposure with a space tilt — which is the opposite trade from what you'd build with UFO/ARKX/NASA.

Decision tree: passive broad → UFO; active concentrated → ARKX; SpaceX wrapper → NASA; defense-prime sleeve → ITA.

Structural risk: index methodology, liquidity, tracking error

Methodology risk: the S-Network Space Index's "majority of revenue from space" rule is self-classified, with limited independent audit. SiriusXM at 4.51% is the obvious test case — does satellite-radio revenue belong in a space ETF? S-Network says yes. A reasonable investor might say no. If S-Network ever tightens its definition (as the index trustees have hinted they will at the 2026 methodology review), UFO could see a forced rotation of 15-20% of fund weight, which is a one-time event risk.

Liquidity risk: at $889M AUM the fund is now liquid enough for retail and small-institutional use, but creation/redemption arbitrage can break in fast melt-ups — premium-to-NAV can spike to 40-60 bps intraday during high-volatility prints. The underlying holds illiquid names (MDA Space trades thin on TSX; FLY is post-IPO with limited float), so APs cannot always hedge cleanly.

Tracking error: structurally low (under 10 bps annualized) due to full replication, but during semi-annual rebalances UFO has historically dragged the index by 30-50 bps over the rebalance window because the fund cannot front-run inclusion trades.

Bull / Gap / Optionality

Bull

1. Starlink IPO Fast-Track inclusion. The S-Network index revised methodology in 2025 to allow rapid inclusion of newly public companies — Starlink, if it IPOs in Q3 2026 as rumored, would be added off-cycle. Even at conservative free-float assumptions, Starlink would enter UFO at 8-10% weight day one, the new top position. That's a mechanical bid into UFO from every ETF AP and indexer on listing day.

2. AUM scaling unlocks institutional flows. UFO crossed $500M AUM in late 2025 and $889M today; the next thresholds ($1B, then $2.5B) unlock pension and insurance allocations that are currently size-blocked. Each threshold has historically driven 6-12 weeks of sustained inflows.

3. Broadest single-ticker beta to a space melt-up. UFO has rallied alongside the pure-plays (+14.8% above 50MA, RSI 71.7) but with materially less single-name idiosyncratic risk than RKLB or RDW individually. For an allocator who wants to add space without owning the single-name drawdown risk, UFO is the default vehicle.

4. Pure-play floor at 80% of weight. Unlike ITA where space exposure is <10% of fund, UFO is guaranteed by methodology to keep ≥80% of weight in space-revenue-majority names. That's a structural protection against fund drift as the index sponsor adds adjacencies.

Gap

1. RSI 71.7 / +14.8% vs 50MA — already extended. UFO is in the same melt-up tape as its underlyings. Buying here means buying after a 15% rally on the 50MA basis; a normal mean-reversion would take UFO to $53-55 (the 50MA), a 10-13% drawdown.

2. ~20% of weight is legacy satcom drag. SIRI, VSAT, IRDM, GSAT combined ~19.7% of fund. These names do NOT participate in space-launch / new-space rallies — they trade off satellite-radio subscribers and legacy ground-station bookings. So UFO underperforms ARKX during pure-play melt-ups and only catches up in broad rotation.

3. RKLB concentration drift. RKLB now 7.37% vs ~5% target at last rebalance. Single-name RKLB drawdown of 30% (plausible given RSI 69 + scanner EXIT_WARN) takes ~2.2% off UFO directly before any sympathy moves in the rest of the basket.

4. Premium-to-NAV widening in fast tape. Today UFO is likely trading 20-40 bps premium to NAV due to flow imbalance. Buying the premium means giving back that drag on any cool-off in volatility.

Optionality

The trade

UFO is the right primary hedge ETF for the Space theme — broadest pure-play exposure, lowest single-name idio risk, mechanical inclusion of Starlink whenever it lists — but the entry is wrong today. RSI 71.7 and +14.8% vs 50MA means you're chasing. The trade is to wait for one of two setups: either (a) a pullback to $58-60 area (within ±5% of current and just above 50MA $53.73), or (b) a confirmed close above $63 on a Starlink IPO catalyst with volume expansion. Entry zone: $58.62-$64.79 (current ±5%). Sizing: 2.5% of risk capital as a hedge sleeve, can scale to 4% if used as a substitute for individual single-name positions. Stop: $53.73 (50MA, ~13% below current — wide because this is a hedge, not a thesis trade). Catalyst: June 2026 semi-annual rebalance + Starlink IPO Fast-Track window. Pivot: if you want a cleaner expression of just the new-space melt-up without the satcom legacy drag, ARKX is more concentrated in the names that actually move; if you specifically want SpaceX exposure, NASA is the only listed ETF that gives it to you.

Conviction: 6 / 10. The vehicle is right; the entry needs to come to you.
