📈
Buying streak — 1 quarter in a row
For 1 consecutive quarter, more hedge funds added IONR 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
21 hedge funds hold IONR 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 — +250% more funds vs a year ago
fund count last 6Q
+15 new funds entered over the past year (+250% 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 buyers than sellers — 71% buying
15 buying6 selling
Last quarter: 15 funds were net buyers (11 opened a brand new position + 4 added to an existing one). Only 6 were sellers (4 trimmed + 2 sold completely). A clear majority buying is a strong confirmation signal.
📈
More new buyers each quarter (+8 vs last Q)
new funds entering per quarter
Funds opening a new IONR position: 2 → 5 → 3 → 11. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.
🔄
Mostly new holders — 62% entered in last year
■ 10% conviction (2yr+)
■ 29% medium
■ 62% new
Only 2 funds (10%) 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 +295% but shares only +267% — price-driven
Last quarter: the total dollar value of institutional holdings rose +295%, but actual share count only changed +267%. 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.
📈
Growing discovery — still being found
3 → 2 → 5 → 3 → 11 new funds/Q
New funds entering each quarter: 2 → 5 → 3 → 11. A growing number of institutions are discovering IONR each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.
🌱
Early stage — 71% of holders entered in last year
■ 24% veterans
■ 5% 1-2yr
■ 71% new
Of 21 current holders: 15 (71%) entered in the past year, only 5 (24%) 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.
📋
Smaller funds dominant — 13% AUM from top-100
13% from top-100 AUM funds
4 of 21 holders rank in the top 100 by AUM, but together hold only 13% of total institutional value. The stock is held primarily by smaller and mid-sized funds.

Moderate Exit Risk
Exit risk score 6.4/10 — some crowding factors present, but no critical concentration. Watch ownership trend over the next 1–2 quarters for direction.
