Smart Money Signals — CABA

Based on 141 hedge funds · latest filing: 2026 Q2 · updated quarterly

📈

Buying streak — 3 quarters in a row

last 6Q
For 3 consecutive quarters, more hedge funds added CABA 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.
📊

High ownership — 92% of 3.0Y peak

92% of all-time peak
141 funds currently hold this stock — 92% of the 3.0-year high of 154 funds (reached 2024 Q1). Ownership is elevated but not yet at maximum concentration. Room to grow, but watch if the trend reverses.
🚀

Fast accumulation — +66% more funds vs a year ago

fund count last 6Q
+56 new funds entered over the past year (+66% 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 — 69% buying

104 buying47 selling
Last quarter: 104 funds were net buyers (53 opened a brand new position + 51 added to an existing one). Only 47 were sellers (24 trimmed + 23 sold completely). A clear majority buying is a strong confirmation signal.
📈

More new buyers each quarter (+24 vs last Q)

new funds entering per quarter
Funds opening a new CABA position: 13 → 30 → 29 → 53. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.
🔒

43% of holders stayed for 2+ years

■ 43% conviction (2yr+) ■ 27% medium ■ 30% new
60 out of 141 hedge funds have held CABA 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.
💰

Value +112% but shares only +85% — price-driven

Value
+112%
Shares
+84%
Last quarter: the total dollar value of institutional holdings rose +112%, but actual share count only changed +85%. 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

27 → 13 → 30 → 29 → 53 new funds/Q
New funds entering each quarter: 13 → 30 → 29 → 53. 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.
🏛️

Veteran-anchored — 59% veterans vs 27% newcomers

■ 59% veterans ■ 14% 1-2yr ■ 27% new
Entry-cohort mix of 147 holders: 87 (59%) are 2+ year veterans, 21 entered 1–2 years ago, and 39 (27%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.
🏆

Elite ownership — 51% AUM from top-100 funds

51% from top-100 AUM funds
45 of 138 holders are among the 100 largest funds by AUM, controlling 51% of total institutional value in CABA. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
4.3
out of 10
Moderate Exit Risk
Exit risk score 4.3/10 — 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.
