Smart Money Signals — MIRM

Based on 309 hedge funds · latest filing: 2026 Q1 · updated quarterly

📈

Buying streak — 7 quarters in a row

last 6Q
For 7 consecutive quarters, more hedge funds added MIRM 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
309 hedge funds hold MIRM 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 — +45% more funds vs a year ago

fund count last 6Q
+96 new funds entered over the past year (+45% 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 — 60% buying

186 buying125 selling
Last quarter: 186 funds were net buyers (68 opened a brand new position + 118 added to an existing one). Only 125 were sellers (88 trimmed + 37 sold completely). A clear majority buying is a strong confirmation signal.
📈

More new buyers each quarter (+7 vs last Q)

new funds entering per quarter
Funds opening a new MIRM position: 34 → 70 → 61 → 68. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.
🔒

41% of holders stayed for 2+ years

41% conviction (2yr+) 24% medium 35% new
127 out of 309 hedge funds have held MIRM for over 2 years without selling. Long-term investors are generally harder to shake out during market stress, creating a stable ownership base that limits the risk of sudden capitulation.
💰

Value +28% but shares only +12% — price-driven

Value
+27%
Shares
+11%
Last quarter: the total dollar value of institutional holdings rose +28%, but actual share count only changed +12%. 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

37 → 34 → 70 → 61 → 68 new funds/Q
New funds entering each quarter: 34 → 70 → 61 → 68. A growing number of institutions are discovering MIRM each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.
🏛️

Veteran-anchored — 46% veterans vs 41% newcomers

46% veterans 13% 1-2yr 41% new
Entry-cohort mix of 314 holders: 144 (46%) are 2+ year veterans, 40 entered 1–2 years ago, and 130 (41%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.
🏆

Elite ownership — 44% AUM from top-100 funds

44% from top-100 AUM funds
55 of 307 holders are among the 100 largest funds by AUM, controlling 44% of total institutional value in MIRM. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
4.4
out of 10
Moderate Exit Risk
Exit risk score 4.4/10 — some crowding factors present, but no critical concentration. Watch ownership trend over the next 1–2 quarters for direction.

Methodology note: these Smart Money cards use consecutive 13F disclosure snapshots, not trade-by-trade execution data. "Buying", "selling", "new holders", and "trimmed" refer to quarter-over-quarter changes in reported holders, aggregate shares, or disclosed position values between filings. They are useful for ownership regime analysis and crowding, but they do not imply exact trade timing on the filing date.
