📉
Selling streak — 3 quarters in a row
For 3 consecutive quarters, more hedge funds reduced or closed their NBB 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
62 funds currently hold this stock — 82% of the 3.0-year high of 76 funds (reached 2023 Q4). Ownership is elevated but not yet at maximum concentration. Room to grow, but watch if the trend reverses.
📉
Outflows — 17% fewer funds vs a year ago
fund count last 6Q
13 fewer hedge funds hold NBB compared to a year ago (-17% decline). When institutions consistently reduce their exposure, it's worth exploring the underlying fundamental reasons driving them away.
🟠
More sellers than buyers — 44% buying
24 buying31 selling
Last quarter: 31 funds reduced or exited vs 24 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.

74% of holders stayed for 2+ years
■ 74% conviction (2yr+)
■ 18% medium
■ 8% new
46 out of 62 hedge funds have held NBB 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 -4%, value -60%
Last quarter: funds added -4% more shares while total portfolio value only changed -60%. 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
14 → 8 → 5 → 5 → 4 new funds/Q
New funds entering each quarter: 8 → 5 → 5 → 4. NBB 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 — 71% of holders stayed 2+ years
■ 71% veterans
■ 13% 1-2yr
■ 16% new
Of 62 current holders: 44 (71%) 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.
✅
Strong quality — 36% AUM from major funds
36% from top-100 AUM funds
10 of 62 holders rank in the top 100 by AUM, accounting for 36% of total institutional value held. A meaningful share of the ownership value comes from the most well-resourced institutions.
Exit risk score 2.6/10 — low institutional crowding. Ownership is below peak levels, holder base is relatively sticky, and buying momentum is positive.
