Smart Money Signals — CTMX

Based on 179 hedge funds · latest filing: 2026 Q1 · updated quarterly

📈

Buying streak — 4 quarters in a row

last 6Q
For 4 consecutive quarters, more hedge funds added CTMX 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
179 hedge funds hold CTMX 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 — +180% more funds vs a year ago

fund count last 6Q
+115 new funds entered over the past year (+180% 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 — 73% buying

138 buying51 selling
Last quarter: 138 funds were net buyers (78 opened a brand new position + 60 added to an existing one). Only 51 were sellers (30 trimmed + 21 sold completely). A clear majority buying is a strong confirmation signal.
📈

More new buyers each quarter (+38 vs last Q)

new funds entering per quarter
Funds opening a new CTMX position: 31 → 34 → 40 → 78. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.
📌

Mixed — 39% long-term, 46% new

■ 39% conviction (2yr+) ■ 16% medium ■ 46% new
Of the 179 current holders: 69 (39%) held >2 years, 28 held 1–2 years, and 82 entered in the last year. A mixed base — the stock has long-term believers but also recent buyers who haven't been tested by a downturn yet.
🚀

Acceleration phase — new buyers rushing in

7 → 31 → 34 → 40 → 78 new funds/Q
New funds entering each quarter: 31 → 34 → 40 → 78. 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 — 51% veterans vs 42% newcomers

■ 51% veterans ■ 7% 1-2yr ■ 42% new
Entry-cohort mix of 190 holders: 97 (51%) are 2+ year veterans, 14 entered 1–2 years ago, and 79 (42%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.
🏆

Elite ownership — 40% AUM from top-100 funds

40% from top-100 AUM funds
36 of 177 holders are among the 100 largest funds by AUM, controlling 40% of total institutional value in CTMX. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
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.
