Smart Money Signals — AACB

Based on 47 hedge funds · latest filing: 2025 Q4 · updated quarterly

📈

Buying streak — 3 quarters in a row

last 6Q
For 3 consecutive quarters, more hedge funds added AACB 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
47 hedge funds hold AACB 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.
🚀

Fast accumulation — +4600% more funds vs a year ago

fund count last 6Q
+46 new funds entered over the past year (+4600% YoY). That's a rapid rush of institutional money. Fast accumulation often signals a major thesis — but it also means the stock could fall quickly if that thesis breaks.
🟡

Slight buying edge — 57% buying

16 buying12 selling
Last quarter: 16 funds bought or added vs 12 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.
➡️

Steady new buyers — ~7 new funds per quarter

new funds entering per quarter
Funds opening this position for the first time: 0 → 40 → 6 → 7. A stable flow of new institutional buyers suggests ongoing interest without signs of either acceleration or slowdown.
🔄

Mostly new holders — 91% entered in last year

■ 2% conviction (2yr+) ■ 6% medium ■ 91% new
Only 1 funds (2%) have held >2 years. The majority of current holders are relatively new to the position. New holders tend to sell faster when prices drop — a shallow conviction base that could amplify any sell-off.
💎

Buying through price weakness — shares -1%, value -99%

Value
-99%
Shares
0%
Last quarter: funds added -1% more shares while total portfolio value only changed -99%. Institutions were buying while the price was falling — a high-conviction accumulation signal. They're deliberately loading up on the dip.
⚠️

Saturation — most institutions already know this story

0 → 0 → 40 → 6 → 7 new funds/Q
New funds entering each quarter: 0 → 40 → 6 → 7. Far fewer institutions are entering now vs. a year ago. When the pool of potential new buyers shrinks this fast, future price support from institutional inflows weakens significantly.
🌱

Early stage — 91% of holders entered in last year

■ 9% veterans ■ 0% 1-2yr ■ 91% new
Of 47 current holders: 43 (91%) entered in the past year, only 4 (9%) are 2+ year veterans. This is an early-phase institutional idea — still being discovered. High upside potential if the thesis plays out, but thin conviction base.
📋

Smaller funds dominant — 10% AUM from top-100

10% from top-100 AUM funds
5 of 47 holders rank in the top 100 by AUM, but together hold only 10% of total institutional value. The stock is held primarily by smaller and mid-sized funds.
7.3
out of 10
High Exit Risk
Exit risk score 7.3/10 — multiple crowding signals converge. Institutional ownership is at 100% of its all-time high — near peak crowding. Crowded trades can unwind fast — a single catalyst can trigger a cascade.

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.
