Smart Money Signals — BRK/B

Based on 4440 hedge funds · latest filing: 2025 Q4 · 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
4,440 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 — +8% more funds vs a year ago

fund count last 6Q
+346 new funds entered over the past year (+8% YoY). Gradual, steady growth in institutional ownership is generally a healthy signal — not a speculative rush, but consistent conviction.
🟡

Slight buying edge — 52% buying

2146 buying2008 selling
Last quarter: 2,146 funds bought or added vs 2,008 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.
📈

More new buyers each quarter (+261 vs last Q)

3.4
out of 10
Low Exit Risk
Exit risk score 3.4/10 — 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.
