Favorable Capital Returns

How effectively does the company reward shareholders?

Around the middle of the covered universe — and capital returns are researched separately from the Suggested Investment Score.

Why it stands out

  • More disclosed holders are new or increasing than reducing or exiting.

What holds it back

  • Elevated valuation: the current market price reflects a premium to this company's historical valuation and comparable companies (Valuation Intelligence 41 out of 100, Elevated).

Long-term view

CLEAN HARBORS INC scores 52 on Long-Term Potential (D+), described by the research model as insufficient data. This describes business characteristics only — it is not a forecast of future returns.

Ownership view

Disclosed ownership evidence reads 26 (F): Positive disclosed activity. 3 tracked managers disclosed a position in the latest reporting period. Ownership filings are historical disclosures, not signals.

Valuation view

CLEAN HARBORS INC reads 41 out of 100 on Valuation Intelligence, recorded as Elevated. The stock currently trades above most of its own recent valuation history and above comparable companies. This describes the price being paid relative to the company's financials — it is not a forecast and not a fair value. Valuation Intelligence is a research model and contributes nothing to the Suggested Investment Score or the daily ranking.

Capital returns view

CLEAN HARBORS INC reads 64 out of 100 on Capital Returns Intelligence (Favorable Capital Returns), reflecting a share count falling about 0.7% a year. Direct capital returns are limited because the company continues reinvesting most of its cash. Capital Returns Intelligence is a research model and contributes nothing to the Suggested Investment Score or the daily ranking.

What changed

No meaningful recorded changes in the stored history.

Risk Intelligence is a core model, Long-Term Potential, Fundamental Momentum, Valuation Intelligence and Capital Returns Intelligence are research models, and Ownership Intelligence is supplemental descriptive evidence. Valuation Intelligence and Capital Returns Intelligence each contribute 0% to the Suggested Investment Score. Nothing here is a recommendation.

What kind of price you'd be paying

Valuation is currently the main point of caution: Valuation Intelligence reads 41 out of 100 (D), recorded as Elevated. CLEAN HARBORS INC reads 41 out of 100 on Valuation Intelligence, recorded as Elevated. The stock currently trades above most of its own recent valuation history and above comparable companies.

How the company rewards shareholders

Capital Returns Intelligence reads 64 out of 100 (C), recorded as Favorable Capital Returns. CLEAN HARBORS INC reads 64 out of 100 on Capital Returns Intelligence (Favorable Capital Returns), reflecting a share count falling about 0.7% a year. Direct capital returns are limited because the company continues reinvesting most of its cash.

What could go wrong

Elevated valuation: the current market price reflects a premium to this company's historical valuation and comparable companies (Valuation Intelligence 41 out of 100, Elevated). Data confidence for this company is partial.

Bottom line

No individual layer reaches the strongest band today. Long-Term Potential and Fundamental Momentum and Ownership Intelligence remain the main area to watch. Separately from the score, valuation reads elevated at today's price.

Ownership Intelligence summarizes publicly disclosed activity among professional investment managers, broader institutions, company insiders, and significant strategic owners. It adds context to investment research but is not a validated predictor of future performance. Ownership information is publicly reported with a delay; the latest applicable reporting period is 2026-06-30, publicly disclosed 9/11/2026. Congressional activity is unavailable pending legal review and contributes nothing to this reading.

Why it ranks here

No component ranks in the top quartile of the qualified universe.

What holds it back

  • Risk Intelligence is less favourable

    Defensive characteristics rank below the middle of the qualified universe.

  • Long-term potential is mid-pack

    Long-Term Potential ranks below the qualified median. This remains a research model.

  • Fundamental Momentum is softer

    Reported business trends rank below the qualified median.

  • Ownership evidence is not uniformly supportive

    Disclosed elite investor activity evidence is weak or neutral. Ownership evidence is supplemental and never automatically positive.

  • Ownership evidence disagrees

    Different owner groups point in different directions, so the combined reading is best read as mixed rather than uniformly favourable.

Score explanation

Why this company scores the way it does

Four research areas carry fixed weights. Each area is compared against every other eligible company, then weighted. The four contributions below add to 32.9 of the stored score (32.9).

  • Risk Intelligence

    30% of the score · contributes 12.7 points

    How strong and defensively sound is the company?

    Stands at the 42 percentile of eligible companies · stored reading 62 · 39% of this company’s total score

    How financially sturdy the company has been when conditions turned against it.

    How this area is measured

    Risk Intelligence reads stored balance-sheet strength, historical downside behaviour and the company's price-risk grouping. A stronger reading describes past resilience; it does not protect against future losses.

    Full methodology
  • Long-Term Potential

    30% of the score · contributes 13.0 points

    Does the business have the characteristics needed to create value over many years?

    Stands at the 43 percentile of eligible companies · stored reading 52 · 40% of this company’s total score

    Whether the business has the durable characteristics long-term owners look for.

    How this area is measured

    Long-Term Potential reads durability characteristics such as profitability consistency, cash generation and reinvestment capability over multiple reported periods.

    Full methodology
  • Fundamental Momentum

    20% of the score · contributes 6.8 points

    Is the underlying business getting stronger or weaker?

    Stands at the 34 percentile of eligible companies · stored reading 44 · 21% of this company’s total score

    Whether the reported business results have been getting stronger or weaker.

    How this area is measured

    Fundamental Momentum compares recent reported fundamentals with the company's own earlier periods, so improvement or deterioration is measured against its history rather than against a forecast.

    Full methodology
  • Ownership Intelligence

    20% of the score · contributes 0.4 points

    What are important owners actually doing?

    Stands at the 2 percentile of eligible companies · stored reading 26 · 1% of this company’s total score

    What large reporting owners have actually been doing with their positions.

    How this area is measured

    Ownership Intelligence reads public ownership filings: how many tracked reporting owners hold the company, and whether they were adding, holding, reducing or exiting in the latest disclosed period.

    Full methodology

What is helping the score

No research area currently stands in the stronger half of eligible companies.

Valuation is inherently uncertain. A stock that appears inexpensive can continue falling, and a stock that appears expensive can continue rising. Valuation Intelligence provides context about the price investors are paying — it does not predict short-term market movements, and it never produces a fair value, a price target or a buy or sell range.

Stored readings only. History builds forward from activation rather than being reconstructed.

Only one stored reading exists for this measure so far, so there is nothing to chart yet.

Why higher yield isn't always better

A very high dividend yield may reflect a falling share price or an unsustainable payout. Capital Returns Intelligence emphasizes consistency and sustainability rather than simply rewarding the highest yield.

Why buybacks can be misleading

Announced or gross buyback spending does not always mean shareholders are gaining ownership. Companies can simultaneously issue shares through employee compensation or acquisitions. Suggested Investments therefore considers actual share-count changes alongside repurchase spending.

What these terms mean
Dividend Yield
The annual dividend relative to the current share price.
Payout Ratio
The share of company earnings used to pay dividends.
Free Cash Flow Payout
How much of the company's available cash is being used for dividends.
Share Repurchases
When a company buys back its own stock.
Dilution
When the number of shares increases, reducing each existing share's percentage ownership of the company.
Shareholder Yield
A combined view of dividends and net share repurchases relative to the company's market value.

Capital Returns Intelligence describes how a company returns capital to shareholders. It is not a measure of stock-price performance, it does not predict future returns, and a strong reading is never a recommendation to buy. Dividends and repurchases can be reduced or stopped at any time. Model CAPITAL_RETURNS_INTELLIGENCE_V1, contributing 0% to the Suggested Investment Score.
