Smart Money Signals — MREO

Based on 71 hedge funds · latest filing: 2025 Q4 · updated quarterly

📉

Selling streak — 1 quarter in a row

last 6Q
For 1 consecutive quarter, 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.
📊

High ownership — 82% of 3.0Y peak

82% of all-time peak
71 funds currently hold this stock — 82% of the 3.0-year high of 87 funds (reached 2024 Q4). Ownership is elevated but not yet at maximum concentration. Room to grow, but watch if the trend reverses.
📉

Outflows — 18% fewer funds vs a year ago

fund count last 6Q
16 fewer hedge funds hold MREO compared to a year ago (-18% decline). When institutions consistently reduce their exposure, it's worth exploring the underlying fundamental reasons driving them away.
🟠

More sellers than buyers — 45% buying

43 buying53 selling
Last quarter: 53 funds reduced or exited vs 43 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.
➡️

Value
-99%
Shares
-35%
Last quarter: funds added -35% more shares while total portfolio value only changed -99%. Institutions were buying while the price was falling — a high-conviction accumulation signal. They're deliberately loading up on the dip.
📈

18 → 13 → 12 → 16 → 21 new funds/Q

Deep conviction — 63% of holders stayed 2+ years

■ 63% veterans ■ 7% 1-2yr ■ 30% new

7% from top-100 AUM funds

3.1
out of 10
Low Exit Risk
Exit risk score 3.1/10 — low institutional crowding. Ownership is below peak levels, holder base is relatively sticky, and buying momentum is positive.

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.
