Smart Money Signals — ASMB

Based on 71 hedge funds · latest filing: 2026 Q1 · updated quarterly

📈

Buying streak — 3 quarters in a row

last 6Q
For 3 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
71 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 — +97% more funds vs a year ago

fund count last 6Q
+35 new funds entered over the past year (+97% 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 — 60% buying

43 buying29 selling
Last quarter: 43 funds were net buyers (14 opened a brand new position + 29 added to an existing one). Only 29 were sellers (17 trimmed + 12 sold completely). A clear majority buying is a strong confirmation signal.
⚠️

Fewer new buyers each quarter (-7 vs last Q)

new funds entering per quarter
Funds opening this position for the first time: 6 → 31 → 21 → 14. 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.
🔄

Mostly new holders — 59% entered in last year

■ 15% conviction (2yr+) ■ 25% medium ■ 59% new
Only 11 funds (15%) 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 -20%

Value
-20%
Shares
-1%
Last quarter: funds added -1% more shares while total portfolio value only changed -20%. Institutions were buying while the price was falling — a high-conviction accumulation signal. They're deliberately loading up on the dip.
➡️

Steady discovery — ~14 new funds/quarter

5 → 6 → 31 → 21 → 14 new funds/Q
New funds entering each quarter: 6 → 31 → 21 → 14. Consistent flow of new institutional buyers without clear acceleration or slowdown.
🌱

Early stage — 61% of holders entered in last year

■ 6% veterans ■ 34% 1-2yr ■ 61% new
Of 71 current holders: 43 (61%) entered in the past year, only 4 (6%) 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 — 12% AUM from top-100

12% from top-100 AUM funds
21 of 71 holders rank in the top 100 by AUM, but together hold only 12% of total institutional value. The stock is held primarily by smaller and mid-sized funds.
5.8
out of 10
Moderate Exit Risk
Exit risk score 5.8/10 — 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.
