📈
Buying streak — 4 quarters in a row
For 4 consecutive quarters, more hedge funds added SPXX than sold it. That's a consistent pattern of professional buying — not a one-time trade. When institutions keep buying quarter after quarter, it usually means they see a multi-year opportunity, not just a short-term momentum flip.
🏔️
At the ownership peak (100% of max)
100% of all-time peak
231 hedge funds hold SPXX right now — the highest count in 3.0 years. When ownership is this concentrated, any bad news can trigger a chain reaction: one big fund sells, others follow. This is a classic 'crowded trade' — high popularity doesn't equal safety.
🚀
Fast accumulation — +391% more funds vs a year ago
fund count last 6Q
+184 new funds entered over the past year (+391% YoY). That's a rapid rush of institutional money. Fast accumulation often signals a major thesis — but it also means the stock could fall quickly if that thesis breaks.
🟠
More sellers than buyers — 45% buying
93 buying114 selling
Last quarter: 114 funds reduced or exited vs 93 that bought or added. When more than half of active funds are selling, it's a caution flag — especially if the stock price hasn't moved down yet.
⚠️
Fewer new buyers each quarter (-141 vs last Q)
new funds entering per quarter
Funds opening this position for the first time: 7 → 16 → 172 → 31. Each quarter fewer new institutions are entering. This usually means most funds that wanted in are already in — the stock is well-known but the pool of potential new buyers is shrinking.
🔄
Mostly new holders — 71% entered in last year
■ 22% conviction (2yr+)
■ 8% medium
■ 71% new
Only 50 funds (22%) have held >2 years. The majority of current holders are relatively new to the position. New holders tend to sell faster when prices drop — a shallow conviction base that could amplify any sell-off.
💰
Value +18% but shares only +2% — price-driven
Last quarter: the total dollar value of institutional holdings rose +18%, but actual share count only changed +2%. The gap is explained by the stock's price rising — not new buying. Strong value growth with weak share growth means the rally is price momentum, not fresh institutional demand.
🚀
Acceleration phase — new buyers rushing in
6 → 7 → 16 → 172 → 31 new funds/Q
New funds entering each quarter: 7 → 16 → 172 → 31. The pace of institutional discovery is accelerating sharply. This is the 'hot idea' phase — the thesis is being passed from fund to fund. You are not late — the accumulation wave is still building.
🌱
Early stage — 69% of holders entered in last year
■ 26% veterans
■ 5% 1-2yr
■ 69% new
Of 231 current holders: 159 (69%) entered in the past year, only 61 (26%) are 2+ year veterans. This is an early-phase institutional idea — still being discovered. High upside potential if the thesis plays out, but thin conviction base.
🏆
Elite ownership — 56% AUM from top-100 funds
56% from top-100 AUM funds
20 of 231 holders are among the 100 largest funds by AUM, controlling 56% of total institutional value in SPXX. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
Exit risk score 7.0/10 — multiple crowding signals converge. Institutional ownership is at 100% of its all-time high — near peak crowding. Selling pressure exceeds buying: only 45% of active funds buying. Crowded trades can unwind fast — a single catalyst can trigger a cascade.
