🏔️

At the ownership peak (96% of max)

96% of all-time peak
351 hedge funds hold MIR 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.
📶

Steady growth — +16% more funds vs a year ago

fund count last 6Q
+49 new funds entered over the past year (+16% YoY). Gradual, steady growth in institutional ownership is generally a healthy signal — not a speculative rush, but consistent conviction.
🟡

Slight buying edge — 52% buying

205 buying191 selling
Last quarter: 205 funds bought or added vs 191 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 — ~60 new funds per quarter

new funds entering per quarter
Funds opening this position for the first time: 90 → 86 → 59 → 60. A stable flow of new institutional buyers suggests ongoing interest without signs of either acceleration or slowdown.

147 out of 351 hedge funds have held MIR 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.
📊

Peak discovery — momentum slowing

101 → 90 → 86 → 59 → 60 new funds/Q
New funds entering each quarter: 90 → 86 → 59 → 60. MIR is well-known in the hedge fund world, but fresh entries are gradually declining. The explosive phase of institutional discovery is likely behind us.
🏛️

Veteran-anchored — 48% veterans vs 36% newcomers

■ 48% veterans ■ 16% 1-2yr ■ 36% new
Entry-cohort mix of 371 holders: 179 (48%) are 2+ year veterans, 59 entered 1–2 years ago, and 133 (36%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.

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.
