📈
Buying streak — 4 quarters in a row
For 4 consecutive quarters, more hedge funds added B than sold it. That's a consistent pattern of professional buying — not a one-time trade. When institutions keep buying quarter after quarter, it usually means they see a multi-year opportunity, not just a short-term momentum flip.
🏔️
At the ownership peak (100% of max)
100% of all-time peak
970 hedge funds hold B right now — the highest count in 3.0 years. When ownership is this concentrated, any bad news can trigger a chain reaction: one big fund sells, others follow. This is a classic 'crowded trade' — high popularity doesn't equal safety.
🚀
Fast accumulation — +32233% more funds vs a year ago
fund count last 6Q
+967 new funds entered over the past year (+32233% 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.
🟡
Slight buying edge — 55% buying
529 buying427 selling
Last quarter: 529 funds bought or added vs 427 that reduced or exited. It's nearly a 50/50 split — some institutions are convinced, others are taking profits. This mixed picture is normal near price highs.
➡️
Steady new buyers — ~223 new funds per quarter
new funds entering per quarter
Funds opening this position for the first time: 6 → 661 → 219 → 223. A stable flow of new institutional buyers suggests ongoing interest without signs of either acceleration or slowdown.
🔄
Mostly new holders — 93% entered in last year
■ 3% conviction (2yr+)
■ 4% medium
■ 93% new
Only 32 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 +1%, value -66%
Last quarter: funds added +1% more shares while total portfolio value only changed -66%. 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
0 → 6 → 661 → 219 → 223 new funds/Q
New funds entering each quarter: 6 → 661 → 219 → 223. B is well-known in the hedge fund world, but fresh entries are gradually declining. The explosive phase of institutional discovery is likely behind us.
🌱
Early stage — 98% of holders entered in last year
■ 2% veterans
■ 0% 1-2yr
■ 98% new
Of 1,040 current holders: 1,014 (98%) entered in the past year, only 26 (2%) 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.
🏆
Elite ownership — 45% AUM from top-100 funds
45% from top-100 AUM funds
45 of 970 holders are among the 100 largest funds by AUM, controlling 45% of total institutional value in B. 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 7.3/10 — multiple crowding signals converge. Institutional ownership is at 100% of its all-time high — near peak crowding. Crowded trades can unwind fast — a single catalyst can trigger a cascade.
