Smart Money Signals — ASMB

Based on 69 hedge funds · latest filing: 2025 Q4 · updated quarterly

📈

Buying streak — 2 quarters in a row

last 6Q
For 2 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
69 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 — +109% more funds vs a year ago

fund count last 6Q
+36 new funds entered over the past year (+109% 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

45 buying23 selling
Last quarter: 45 funds were net buyers (21 opened a brand new position + 24 added to an existing one). Only 23 were sellers (14 trimmed + 9 sold completely). A clear majority buying is a strong confirmation signal.
⚠️

Fewer new buyers each quarter (-10 vs last Q)

new funds entering per quarter
Funds opening this position for the first time: 5 → 6 → 31 → 21. 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 — 55% entered in last year

■ 6% conviction (2yr+) ■ 39% medium ■ 55% new
Only 4 funds (6%) 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.
💰

Value +39% but shares only +6% — price-driven

Value
+39%
Shares
+5%
Last quarter: the total dollar value of institutional holdings rose +39%, but actual share count only changed +6%. The gap is explained by the stock's price rising — not new buying. Strong value growth with weak share growth means the rally is price momentum, not fresh institutional demand.
🚀

Acceleration phase — new buyers rushing in

8 → 5 → 6 → 31 → 21 new funds/Q
New funds entering each quarter: 5 → 6 → 31 → 21. The pace of institutional discovery is accelerating sharply. This is the 'hot idea' phase — the thesis is being passed from fund to fund. You are not late — the accumulation wave is still building.
🌱

Early stage — 65% of holders entered in last year

■ 6% veterans ■ 29% 1-2yr ■ 65% new
Of 69 current holders: 45 (65%) 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 — 16% AUM from top-100

16% from top-100 AUM funds
17 of 69 holders rank in the top 100 by AUM, but together hold only 16% of total institutional value. The stock is held primarily by smaller and mid-sized funds.
6.1
out of 10
Moderate Exit Risk
Exit risk score 6.1/10 — 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.
