Smart Money Signals — MIRM

Based on 330 hedge funds · latest filing: 2026 Q2 · updated quarterly

📈

Buying streak — 8 quarters in a row

last 6Q
For 8 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
330 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 — +54% more funds vs a year ago

fund count last 6Q
+116 new funds entered over the past year (+54% 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

193 buying147 selling
Last quarter: 193 funds bought or added vs 147 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.
➡️

Steady new buyers — ~67 new funds per quarter

new funds entering per quarter
Funds opening this position for the first time: 71 → 61 → 68 → 67. A stable flow of new institutional buyers suggests ongoing interest without signs of either acceleration or slowdown.
📌

Mixed — 39% long-term, 36% new

■ 39% conviction (2yr+) ■ 25% medium ■ 36% new
Of the 330 current holders: 130 (39%) held >2 years, 81 held 1–2 years, and 119 entered in the last year. A mixed base — the stock has long-term believers but also recent buyers who haven't been tested by a downturn yet.
💰

Value +32% but shares only +13% — price-driven

Value
+31%
Shares
+12%
Last quarter: the total dollar value of institutional holdings rose +32%, but actual share count only changed +13%. 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.
➡️

Steady discovery — ~67 new funds/quarter

34 → 71 → 61 → 68 → 67 new funds/Q
New funds entering each quarter: 71 → 61 → 68 → 67. Consistent flow of new institutional buyers without clear acceleration or slowdown.
🏛️

Veteran-anchored — 44% veterans vs 42% newcomers

■ 44% veterans ■ 13% 1-2yr ■ 42% new
Entry-cohort mix of 335 holders: 148 (44%) are 2+ year veterans, 45 entered 1–2 years ago, and 142 (42%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.
✅

Strong quality — 36% AUM from major funds

36% from top-100 AUM funds
53 of 327 holders rank in the top 100 by AUM, accounting for 36% 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.
