Smart Money Signals — ACLS

Based on 348 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 ACLS 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.
📊

High ownership — 88% of 3.0Y peak

88% of all-time peak
348 funds currently hold this stock — 88% of the 3.0-year high of 396 funds (reached 2023 Q3). Ownership is elevated but not yet at maximum concentration. Room to grow, but watch if the trend reverses.
📶

Steady growth — +13% more funds vs a year ago

fund count last 6Q
+41 new funds entered over the past year (+13% YoY). Gradual, steady growth in institutional ownership is generally a healthy signal — not a speculative rush, but consistent conviction.
🟡

Slight buying edge — 51% buying

182 buying174 selling
Last quarter: 182 funds bought or added vs 174 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 (-9 vs last Q)

new funds entering per quarter
Funds opening this position for the first time: 43 → 66 → 75 → 66. 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
211 out of 348 hedge funds have held ACLS 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
-14%
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.
📈

Growing discovery — still being found

55 → 43 → 66 → 75 → 66 new funds/Q
New funds entering each quarter: 43 → 66 → 75 → 66. A growing number of institutions are discovering ACLS each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.
🏛️

Deep conviction — 66% of holders stayed 2+ years

■ 66% veterans ■ 11% 1-2yr ■ 23% new
Of 361 current holders: 239 (66%) 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 — 50% AUM from top-100 funds

50% from top-100 AUM funds
41 of 348 holders are among the 100 largest funds by AUM, controlling 50% of total institutional value in ACLS. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
3.2
out of 10
Low Exit Risk
Exit risk score 3.2/10 — 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.
