Smart Money Signals — ASMB

Based on 91 hedge funds · latest filing: 2026 Q2 · updated quarterly

📈

Buying streak — 4 quarters in a row

last 6Q
For 4 consecutive quarters, more hedge funds added ASMB 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
91 hedge funds hold ASMB 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 — +168% more funds vs a year ago

fund count last 6Q
+57 new funds entered over the past year (+168% 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.
🟢

More buyers than sellers — 66% buying

69 buying35 selling
Last quarter: 69 funds were net buyers (37 opened a brand new position + 32 added to an existing one). Only 35 were sellers (18 trimmed + 17 sold completely). A clear majority buying is a strong confirmation signal.
📈

More new buyers each quarter (+23 vs last Q)

new funds entering per quarter
Funds opening a new ASMB position: 31 → 21 → 14 → 37. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.
🔄

Mostly new holders — 57% entered in last year

■ 16% conviction (2yr+) ■ 26% medium ■ 57% new
Only 15 funds (16%) 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.
➡️

Steady discovery — ~37 new funds/quarter

6 → 31 → 21 → 14 → 37 new funds/Q
New funds entering each quarter: 31 → 21 → 14 → 37. Consistent flow of new institutional buyers without clear acceleration or slowdown.
🌱

Early stage — 63% of holders entered in last year

■ 17% veterans ■ 19% 1-2yr ■ 63% new
Of 93 current holders: 59 (63%) entered in the past year, only 16 (17%) 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 — 15% AUM from top-100

15% from top-100 AUM funds
32 of 90 holders rank in the top 100 by AUM, but together hold only 15% of total institutional value. The stock is held primarily by smaller and mid-sized funds.
5.4
out of 10
Moderate Exit Risk
Exit risk score 5.4/10 — some crowding factors present, but no critical concentration. Watch ownership trend over the next 1–2 quarters for direction.

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.
