Smart Money Signals — MREO

Based on 58 hedge funds · latest filing: 2026 Q2 · updated quarterly

📉

Selling streak — 3 quarters in a row

last 6Q
For 3 consecutive quarters, more hedge funds reduced or closed their MREO positions than added to them. Sustained institutional selling is a meaningful warning sign — these are professionals with deep research teams collectively deciding to exit.
🔻

Below peak — only 65% of 3.0Y high

65% of all-time peak
Only 58 funds hold MREO today versus a peak of 89 funds at 2024 Q4 — just 65% of the maximum. Low institutional ownership can mean the stock is out of favor, but it also means there's a large pool of potential buyers if sentiment turns.
📉

Outflows — 31% fewer funds vs a year ago

fund count last 6Q
26 fewer hedge funds hold MREO compared to a year ago (-31% decline). When institutions consistently reduce their exposure, it's worth exploring the underlying fundamental reasons driving them away.
🟠

More sellers than buyers — 45% buying

27 buying33 selling
Last quarter: 33 funds reduced or exited vs 27 that bought or added. When more than half of active funds are selling, it's a caution flag — especially if the stock price hasn't moved down yet.
➡️

Steady new buyers — ~14 new funds per quarter

📊

Peak discovery — momentum slowing

12 → 17 → 21 → 12 → 14 new funds/Q
New funds entering each quarter: 17 → 21 → 12 → 14. MREO 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 — 67% veterans vs 30% newcomers

■ 67% veterans ■ 3% 1-2yr ■ 30% new
Entry-cohort mix of 63 holders: 42 (67%) are 2+ year veterans, 2 entered 1–2 years ago, and 19 (30%) 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.
