Smart Money Signals — ABVX

Based on 306 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 ABVX 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
306 hedge funds hold ABVX 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 — +612% more funds vs a year ago

fund count last 6Q
+263 new funds entered over the past year (+612% 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.
🟡

Slight buying edge — 57% buying

201 buying152 selling
Last quarter: 201 funds bought or added vs 152 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.
📈

More new buyers each quarter (+46 vs last Q)

new funds entering per quarter
Funds opening a new ABVX position: 132 → 104 → 52 → 98. 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

■ 12% conviction (2yr+) ■ 31% medium ■ 57% new
Only 36 funds (12%) 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 +54% but shares only +27% — price-driven

Value
+54%
Shares
+27%
Last quarter: the total dollar value of institutional holdings rose +54%, but actual share count only changed +27%. 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.
📊

Peak discovery — momentum slowing

7 → 132 → 104 → 52 → 98 new funds/Q
New funds entering each quarter: 132 → 104 → 52 → 98. ABVX is well-known in the hedge fund world, but fresh entries are gradually declining. The explosive phase of institutional discovery is likely behind us.
🌱

Early stage — 80% of holders entered in last year

■ 15% veterans ■ 5% 1-2yr ■ 80% new
Of 365 current holders: 291 (80%) entered in the past year, only 54 (15%) 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 — 19% AUM from top-100

19% from top-100 AUM funds
40 of 301 holders rank in the top 100 by AUM, but together hold only 19% 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.
