Smart Money Signals — CMPS

Based on 194 hedge funds · latest filing: 2026 Q1 · updated quarterly

📈

Buying streak — 5 quarters in a row

last 6Q

For 5 consecutive quarters, more hedge funds added CMPS 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

194 hedge funds hold CMPS 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 — +43% more funds vs a year ago

fund count last 6Q

+58 new funds entered over the past year (+43% 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 — 67% buying

124 buying62 selling

Last quarter: 124 funds were net buyers (54 opened a brand new position + 70 added to an existing one). Only 62 were sellers (32 trimmed + 30 sold completely). A clear majority buying is a strong confirmation signal.

📈

More new buyers each quarter (+18 vs last Q)

new funds entering per quarter

■ 46% conviction (2yr+) ■ 25% medium ■ 29% new

89 out of 194 hedge funds have held CMPS 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.

Buying through price weakness — shares +69%, value +35%

Value

+35%

+69%

Last quarter: funds added +69% more shares while total portfolio value only changed +35%. Institutions were buying while the price was falling — a high-conviction accumulation signal. They're deliberately loading up on the dip.

📈

Growing discovery — still being found

25 → 25 → 39 → 36 → 54 new funds/Q

New funds entering each quarter: 25 → 39 → 36 → 54. A growing number of institutions are discovering CMPS each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.

🏛️

Deep conviction — 54% of holders stayed 2+ years

■ 54% veterans ■ 13% 1-2yr ■ 33% new

Of 205 current holders: 111 (54%) have held for over 2 years without selling. These are not momentum buyers — they have lived through drawdowns and stayed. A large veteran base acts as a stabilizing force during selloffs.

📋

Smaller funds dominant — 14% AUM from top-100

14% from top-100 AUM funds

26 of 194 holders rank in the top 100 by AUM, but together hold only 14% of total institutional value. The stock is held primarily by smaller and mid-sized funds.

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.
