📉
Selling streak — 1 quarter in a row
For 1 consecutive quarter, more hedge funds reduced or closed their NRSN 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 — 75% of 3.0Y peak
75% of all-time peak
12 funds currently hold this stock — 75% of the 3.0-year high of 16 funds (reached 2025 Q2). Ownership is elevated but not yet at maximum concentration. Room to grow, but watch if the trend reverses.
📉
Outflows — 25% fewer funds vs a year ago
fund count last 6Q
4 fewer hedge funds hold NRSN compared to a year ago (-25% decline). When institutions consistently reduce their exposure, it's worth exploring the underlying fundamental reasons driving them away.
🟠
More sellers than buyers — 44% buying
4 buying5 selling

■ 17% conviction (2yr+)
■ 42% medium
■ 42% new
Only 2 funds (17%) have held >2 years. The majority of current holders are relatively new to the position. New holders tend to sell faster when prices drop — a shallow conviction base that could amplify any sell-off.
📊
Peak discovery — momentum slowing
8 → 1 → 5 → 3 → 2 new funds/Q
New funds entering each quarter: 1 → 5 → 3 → 2. NRSN is well-known in the hedge fund world, but fresh entries are gradually declining. The explosive phase of institutional discovery is likely behind us.
📊

Elite ownership — 40% AUM from top-100 funds
40% from top-100 AUM funds
5 of 12 holders are among the 100 largest funds by AUM, controlling 40% of total institutional value in NRSN. 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 3.1/10 — low institutional crowding. Ownership is below peak levels, holder base is relatively sticky, and buying momentum is positive.
