📈
Buying streak — 1 quarter in a row
For 1 consecutive quarter, more hedge funds added BRK/A 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
1,316 hedge funds hold BRK/A 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 — +33% more funds vs a year ago
fund count last 6Q
+327 new funds entered over the past year (+33% 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 — 49% buying
205 buying214 selling
Last quarter: 214 funds reduced or exited vs 205 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 (+46 vs last Q)
new funds entering per quarter
Funds opening a new BRK/A position: 357 → 62 → 56 → 102. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.
🔒
67% of holders stayed for 2+ years
■ 67% conviction (2yr+)
■ 24% medium
■ 9% new
878 out of 1,316 hedge funds have held BRK/A 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 +36394%, value +7%
Last quarter: funds added +36394% more shares while total portfolio value only changed +7%. 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
68 → 357 → 62 → 56 → 102 new funds/Q
New funds entering each quarter: 357 → 62 → 56 → 102. BRK/A 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 — 69% of holders stayed 2+ years
■ 69% veterans
■ 8% 1-2yr
■ 24% new
Of 1,318 current holders: 906 (69%) 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 — 49% AUM from top-100 funds
49% from top-100 AUM funds
38 of 1316 holders are among the 100 largest funds by AUM, controlling 49% of total institutional value in BRK/A. 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 3.5/10 — low institutional crowding. Ownership is below peak levels, holder base is relatively sticky, and buying momentum is positive.
