Selling streak — 1 quarter in a row
For 1 consecutive quarter, more hedge funds reduced or closed their BA positions than added to them. Sustained institutional selling is a meaningful warning sign — these are professionals with deep research teams collectively deciding to exit.
🏔️
At the ownership peak (100% of max)
100% of all-time peak
2,513 hedge funds hold BA 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 — +20% more funds vs a year ago
fund count last 6Q
+419 new funds entered over the past year (+20% YoY). Gradual, steady growth in institutional ownership is generally a healthy signal — not a speculative rush, but consistent conviction.
🟡
Slight buying edge — 58% buying
1387 buying1023 selling
Last quarter: 1,387 funds bought or added vs 1,023 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.
⚠️
Fewer new buyers each quarter (-125 vs last Q)
new funds entering per quarter
