Smart Money Signals — BRK/B

Based on 4816 hedge funds · latest filing: 2026 Q1 · updated quarterly

📈

Buying streak — 11 quarters in a row

last 6Q
For 11 consecutive quarters, more hedge funds added BRK/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
4,816 hedge funds hold BRK/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.
📶

Steady growth — +9% more funds vs a year ago

fund count last 6Q
+380 new funds entered over the past year (+9% YoY). Gradual, steady growth in institutional ownership is generally a healthy signal — not a speculative rush, but consistent conviction.
🟠

More sellers than buyers — 49% buying

2216 buying2274 selling
Last quarter: 2,274 funds reduced or exited vs 2,216 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 (-247 vs last Q)

new funds entering per quarter
Funds opening this position for the first time: 244 → 220 → 519 → 272. 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.
🔒

70% of holders stayed for 2+ years

■ 70% conviction (2yr+) ■ 17% medium ■ 13% new
3,361 out of 4,816 hedge funds have held BRK/B 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.
🚀

Acceleration phase — new buyers rushing in

272 → 244 → 220 → 519 → 272 new funds/Q
New funds entering each quarter: 244 → 220 → 519 → 272. The pace of institutional discovery is accelerating sharply. This is the 'hot idea' phase — the thesis is being passed from fund to fund. You are not late — the accumulation wave is still building.
🏛️

Deep conviction — 69% of holders stayed 2+ years

■ 69% veterans ■ 14% 1-2yr ■ 16% new
Of 4,908 current holders: 3,411 (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 — 41% AUM from top-100 funds

41% from top-100 AUM funds
66 of 4816 holders are among the 100 largest funds by AUM, controlling 41% of total institutional value in BRK/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.
3.5
out of 10
Low Exit Risk
Exit risk score 3.5/10 — low institutional crowding. Ownership is below peak levels, holder base is relatively sticky, and buying momentum is positive.

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.
