Smart Money Signals — AMBA

Based on 323 hedge funds · latest filing: 2025 Q4 · updated quarterly

📉

Selling streak — 1 quarter in a row

last 6Q
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 (96% of max)

96% of all-time peak
323 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 — +9% more funds vs a year ago

fund count last 6Q
+27 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 — 45% buying

163 buying199 selling
Last quarter: 199 funds reduced or exited vs 163 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 (-10 vs last Q)

new funds entering per quarter
Funds opening this position for the first time: 59 → 61 → 69 → 59. 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.
🔒

60% of holders stayed for 2+ years

■ 60% conviction (2yr+) ■ 19% medium ■ 21% new
194 out of 323 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%

Value
-13%
Shares
+2%
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 — ~59 new funds/quarter

71 → 59 → 61 → 69 → 59 new funds/Q
New funds entering each quarter: 59 → 61 → 69 → 59. Consistent flow of new institutional buyers without clear acceleration or slowdown.
🏛️

Deep conviction — 69% of holders stayed 2+ years

■ 69% veterans ■ 7% 1-2yr ■ 23% new
Of 347 current holders: 241 (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
51 of 323 holders are among the 100 largest funds by AUM, controlling 49% of total institutional value in AMBA. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
3.8
out of 10
Low Exit Risk
Exit risk score 3.8/10 — 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.
