Smart Money Signals — BBNX

Based on 129 hedge funds · latest filing: 2026 Q1 · updated quarterly

📉

Selling streak — 1 quarter in a row

last 6Q
For 1 consecutive quarter, more hedge funds reduced or closed their BBNX 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 — 83% of 3.0Y peak

83% of all-time peak
129 funds currently hold this stock — 83% of the 3.0-year high of 155 funds (reached 2025 Q4). Ownership is elevated but not yet at maximum concentration. Room to grow, but watch if the trend reverses.
🚀

Fast accumulation — +26% more funds vs a year ago

fund count last 6Q
+27 new funds entered over the past year (+26% YoY). That's a rapid rush of institutional money. Fast accumulation often signals a major thesis — but it also means the stock could fall quickly if that thesis breaks.
🟠

More sellers than buyers — 42% buying

70 buying96 selling
Last quarter: 96 funds reduced or exited vs 70 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.
⚠️

Fewer new buyers each quarter (-25 vs last Q)

new funds entering per quarter
Funds opening this position for the first time: 26 → 28 → 48 → 23. Each quarter fewer new institutions are entering. This usually means most funds that wanted in are already in — the stock is well-known but the pool of potential new buyers is shrinking.
🔄

Mostly new holders — 38% entered in last year

■ 3% conviction (2yr+) ■ 59% medium ■ 38% new
Only 4 funds (3%) 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.
💎

Buying through price weakness — shares +4%, value -65%

Value
-65%
Shares
+4%
Last quarter: funds added +4% more shares while total portfolio value only changed -65%. Institutions were buying while the price was falling — a high-conviction accumulation signal. They're deliberately loading up on the dip.
📈

Growing discovery — still being found

102 → 26 → 28 → 48 → 23 new funds/Q
New funds entering each quarter: 26 → 28 → 48 → 23. A growing number of institutions are discovering BBNX each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.
🌱

Early stage — 94% of holders entered in last year

■ 6% veterans ■ 0% 1-2yr ■ 94% new
Of 130 current holders: 122 (94%) entered in the past year, only 8 (6%) are 2+ year veterans. This is an early-phase institutional idea — still being discovered. High upside potential if the thesis plays out, but thin conviction base.
📋

Smaller funds dominant — 18% AUM from top-100

18% from top-100 AUM funds
33 of 128 holders rank in the top 100 by AUM, but together hold only 18% of total institutional value. The stock is held primarily by smaller and mid-sized funds.
4.0
out of 10
Moderate Exit Risk
Exit risk score 4.0/10 — some crowding factors present, but no critical concentration. Watch ownership trend over the next 1–2 quarters for direction.

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.
