Smart Money Signals — MIRM

Based on 267 hedge funds · latest filing: 2025 Q4 · updated quarterly

📈

Buying streak — 2 quarters in a row

last 6Q
For 2 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
267 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 — +37% more funds vs a year ago

fund count last 6Q
+72 new funds entered over the past year (+37% 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.
🟡

Slight buying edge — 57% buying

160 buying122 selling
Last quarter: 160 funds bought or added vs 122 that reduced or exited. It's nearly a 50/50 split — some institutions are convinced, others are taking profits. This mixed picture is normal near price highs.
⚠️

Fewer new buyers each quarter (-9 vs last Q)

new funds entering per quarter
Funds opening this position for the first time: 36 → 32 → 67 → 58. 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.
🔒

45% of holders stayed for 2+ years

45% conviction (2yr+) 21% medium 34% new
119 out of 267 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.
🚀

Acceleration phase — new buyers rushing in

38 → 36 → 32 → 67 → 58 new funds/Q
New funds entering each quarter: 36 → 32 → 67 → 58. 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.
🏛️

Deep conviction — 49% of holders stayed 2+ years

49% veterans 13% 1-2yr 38% new
Of 272 current holders: 133 (49%) have held for over 2 years without selling. These are not momentum buyers — they have lived through drawdowns and stayed. A large veteran base acts as a stabilizing force during selloffs.

Strong quality — 34% AUM from major funds

34% from top-100 AUM funds
36 of 267 holders rank in the top 100 by AUM, accounting for 34% of total institutional value held. A meaningful share of the ownership value comes from the most well-resourced institutions.
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.
