📉
Selling streak — 1 quarter in a row
For 1 consecutive quarter, more hedge funds reduced or closed their MOS 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 — 92% of 3.0Y peak
92% of all-time peak
608 funds currently hold this stock — 92% of the 3.0-year high of 659 funds (reached 2025 Q3). Ownership is elevated but not yet at maximum concentration. Room to grow, but watch if the trend reverses.
📶
Steady growth — +5% more funds vs a year ago
fund count last 6Q
+27 new funds entered over the past year (+5% YoY). Gradual, steady growth in institutional ownership is generally a healthy signal — not a speculative rush, but consistent conviction. The peak was reached in just 3 quarters from the low — a sharp move.
🟠
More sellers than buyers — 45% buying
330 buying404 selling
Last quarter: 404 funds reduced or exited vs 330 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.
📈
More new buyers each quarter (+10 vs last Q)
new funds entering per quarter
Funds opening a new MOS position: 118 → 144 → 104 → 114. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.
🔒

■ 69% conviction (2yr+)
■ 15% medium
■ 16% new
422 out of 608 hedge funds have held MOS 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.
💎
Buying through price weakness — shares -2%, value -29%
Last quarter: funds added -2% more shares while total portfolio value only changed -29%. Institutions were buying while the price was falling — a high-conviction accumulation signal. They're deliberately loading up on the dip.
📊
Peak discovery — momentum slowing
89 → 118 → 144 → 104 → 114 new funds/Q
New funds entering each quarter: 118 → 144 → 104 → 114. MOS is well-known in the hedge fund world, but fresh entries are gradually declining. The explosive phase of institutional discovery is likely behind us.
🏛️
Deep conviction — 75% of holders stayed 2+ years
■ 75% veterans
■ 8% 1-2yr
■ 17% new
Of 654 current holders: 493 (75%) 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.
🏆
Elite ownership — 64% AUM from top-100 funds
64% from top-100 AUM funds
43 of 608 holders are among the 100 largest funds by AUM, controlling 64% of total institutional value in MOS. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
Exit risk score 3.3/10 — low institutional crowding. Ownership is below peak levels, holder base is relatively sticky, and buying momentum is positive.
