Smart Money Signals — ACET

Based on 48 hedge funds · latest filing: 2026 Q1 · updated quarterly

➡️

No change last quarter

last 6Q
The number of hedge funds holding this stock didn't change last quarter. Neither a buying nor selling signal on its own — watch the next quarter for direction.
🔻

Below peak — only 50% of 3.0Y high

50% of all-time peak
Only 48 funds hold ACET today versus a peak of 96 funds at 2024 Q1 — just 50% of the maximum. Low institutional ownership can mean the stock is out of favor, but it also means there's a large pool of potential buyers if sentiment turns.
📉

Outflows — 16% fewer funds vs a year ago

fund count last 6Q
9 fewer hedge funds hold ACET compared to a year ago (-16% decline). When institutions consistently reduce their exposure, it's worth exploring the underlying fundamental reasons driving them away.
🟡

Slight buying edge — 56% buying

24 buying19 selling
Last quarter: 24 funds bought or added vs 19 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 — ~12 new funds per quarter

new funds entering per quarter
Funds opening this position for the first time: 8 → 13 → 14 → 12. A stable flow of new institutional buyers suggests ongoing interest without signs of either acceleration or slowdown.
🔒

54% of holders stayed for 2+ years

■ 54% conviction (2yr+) ■ 19% medium ■ 27% new
26 out of 48 hedge funds have held ACET 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 -2%, value -22%

Value
-22%
Shares
-2%
Last quarter: funds added -2% more shares while total portfolio value only changed -22%. 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

4 → 8 → 13 → 14 → 12 new funds/Q
New funds entering each quarter: 8 → 13 → 14 → 12. A growing number of institutions are discovering ACET each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.
🏛️

Veteran-anchored — 58% veterans vs 25% newcomers

■ 58% veterans ■ 17% 1-2yr ■ 25% new
Entry-cohort mix of 48 holders: 28 (58%) are 2+ year veterans, 8 entered 1–2 years ago, and 12 (25%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.
✅

Strong quality — 20% AUM from major funds

20% from top-100 AUM funds
13 of 47 holders rank in the top 100 by AUM, accounting for 20% of total institutional value held. A meaningful share of the ownership value comes from the most well-resourced institutions.
1.2
out of 10
Low Exit Risk
Exit risk score 1.2/10 — 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.
