Smart Money Signals — CLH

Based on 622 hedge funds · latest filing: 2026 Q1 · updated quarterly

📈

Buying streak — 2 quarters in a row

last 6Q
For 2 consecutive quarters, more hedge funds added CLH 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
622 hedge funds hold CLH 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.
📶

Steady growth — +13% more funds vs a year ago

fund count last 6Q
+72 new funds entered over the past year (+13% YoY). Gradual, steady growth in institutional ownership is generally a healthy signal — not a speculative rush, but consistent conviction.
🟡

Slight buying edge — 57% buying

329 buying252 selling
Last quarter: 329 funds bought or added vs 252 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 (+22 vs last Q)

new funds entering per quarter
Funds opening a new CLH position: 77 → 75 → 98 → 120. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.
🔒

56% of holders stayed for 2+ years

■ 56% conviction (2yr+) ■ 19% medium ■ 24% new
350 out of 622 hedge funds have held CLH 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.
💰

Price up while funds trimmed (+13% value, -4% shares)

Value
+12%
Shares
-4%
Last quarter: total value of institutional CLH holdings rose +13% even though funds reduced share count by 4%. The stock price increased enough to offset the selling. Institutions are quietly trimming into price strength — watch for rotation.
📈

Growing discovery — still being found

89 → 77 → 75 → 98 → 120 new funds/Q
New funds entering each quarter: 77 → 75 → 98 → 120. A growing number of institutions are discovering CLH each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.
🏛️

Veteran-anchored — 60% veterans vs 26% newcomers

■ 60% veterans ■ 14% 1-2yr ■ 26% new
Entry-cohort mix of 632 holders: 378 (60%) are 2+ year veterans, 87 entered 1–2 years ago, and 167 (26%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.
🏆

Elite ownership — 43% AUM from top-100 funds

43% from top-100 AUM funds
59 of 620 holders are among the 100 largest funds by AUM, controlling 43% of total institutional value in CLH. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
3.7
out of 10
Low Exit Risk
Exit risk score 3.7/10 — low institutional crowding. Ownership is below peak levels, holder base is relatively sticky, and buying momentum is positive.

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.
