📉
Selling streak — 1 quarter in a row
For 1 consecutive quarter, more hedge funds reduced or closed their AMBA 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 (97% of max)
97% of all-time peak
310 hedge funds hold AMBA 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 — +10% more funds vs a year ago
fund count last 6Q
+27 new funds entered over the past year (+10% YoY). Gradual, steady growth in institutional ownership is generally a healthy signal — not a speculative rush, but consistent conviction.
🟠
More sellers than buyers — 45% buying
159 buying192 selling
Last quarter: 192 funds reduced or exited vs 159 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 (-8 vs last Q)
new funds entering per quarter
Funds opening this position for the first time: 57 → 59 → 66 → 58. 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.
🔒
61% of holders stayed for 2+ years
■ 61% conviction (2yr+)
■ 18% medium
■ 21% new
189 out of 310 hedge funds have held AMBA 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 +3%, value -14%
Last quarter: funds added +3% more shares while total portfolio value only changed -14%. Institutions were buying while the price was falling — a high-conviction accumulation signal. They're deliberately loading up on the dip.
➡️
Steady discovery — ~58 new funds/quarter
64 → 57 → 59 → 66 → 58 new funds/Q
New funds entering each quarter: 57 → 59 → 66 → 58. Consistent flow of new institutional buyers without clear acceleration or slowdown.
🏛️
Deep conviction — 71% of holders stayed 2+ years
■ 71% veterans
■ 7% 1-2yr
■ 22% new
Of 334 current holders: 236 (71%) 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.
✅
Strong quality — 38% AUM from major funds
38% from top-100 AUM funds
34 of 310 holders rank in the top 100 by AUM, accounting for 38% of total institutional value held. A meaningful share of the ownership value comes from the most well-resourced institutions.
Exit risk score 3.8/10 — low institutional crowding. Ownership is below peak levels, holder base is relatively sticky, and buying momentum is positive.
