Smart Money Signals — AACB

Based on 48 hedge funds · latest filing: 2026 Q2 · updated quarterly

📉

Selling streak — 1 quarter in a row

last 6Q
For 1 consecutive quarter, more hedge funds reduced or closed their AACB 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
48 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.
📶

Steady growth — +17% more funds vs a year ago

fund count last 6Q
+7 new funds entered over the past year (+17% 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

10 buying12 selling
Last quarter: 12 funds reduced or exited vs 10 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.
➡️

Steady new buyers — ~3 new funds per quarter

new funds entering per quarter
Funds opening this position for the first time: 6 → 7 → 6 → 3. A stable flow of new institutional buyers suggests ongoing interest without signs of either acceleration or slowdown.
🔄

Mostly new holders — 21% entered in last year

■ 4% conviction (2yr+) ■ 75% medium ■ 21% new
Only 2 funds (4%) 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.
📊

Peak discovery — momentum slowing

40 → 6 → 7 → 6 → 3 new funds/Q
New funds entering each quarter: 6 → 7 → 6 → 3. AACB is well-known in the hedge fund world, but fresh entries are gradually declining. The explosive phase of institutional discovery is likely behind us.
🌱

Early stage — 96% of holders entered in last year

■ 4% veterans ■ 0% 1-2yr ■ 96% new
Of 48 current holders: 46 (96%) entered in the past year, only 2 (4%) 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 — 11% AUM from top-100

11% from top-100 AUM funds
6 of 48 holders rank in the top 100 by AUM, but together hold only 11% of total institutional value. The stock is held primarily by smaller and mid-sized funds.
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.
