Participation is not spreading downward this month; the larger companies are still carrying most of it.
Both lines start at 200 in the same week, so the distance between them is the whole story: the industry line is an equal-weighted index of its 6 companies. The bars underneath are trailing 12-month earnings per share, one bar per reported quarter, each member rebased to 100 at the start and the industry taking the median — so a price line pulling away from flat bars is a re-rating, not earnings. A bar turns red when that figure is lower than the quarter before. Rules are fixed and applied identically everywhere on this site: ahead by 5% or more over three months, or behind by 20% or more over a year while earnings grew 20% or more. Hover any point to read both values and the gap. This is a description of what the numbers did, not advice.

4-Factor Sector Score
An additive sector-relative research score. The four displayed point contributions always equal the total: Growth & earnings (35), Capital efficiency (25), Valuation (20), and Relative strength (20). Missing or stale evidence is absorbed inside the affected factor, never applied as a hidden adjustment.
Zurn Elkay Water Solutions Corporation has the strongest current balance of earnings trajectory, business quality, valuation and price confirmation, with 79% evidence confidence.
Missing observations are not scored as bad. Their missing weight lowers confidence and pulls the final score toward neutral. PEG is guarded: positive earnings, positive 5–60% three-year EPS growth, and a positive P/E are required.
Decision use: Fill the missing evidence before acting; the ranking is deliberately pulled toward neutral.

This conclusion weakens if: CAPEX rises without higher utilization, operating cash flow or incremental returns.
CAPEX is cash spent on property, plant, equipment and other reported capital assets. CAPEX intensity divides that spend by revenue; high intensity is a reinvestment signal, not proof that the reinvestment will earn attractive returns.

Capacity base is net fixed assets plus capital work in progress, straight off the reported balance sheet. It is not cash spent, so it answers a narrower question than CAPEX — but it is reported for companies whose cash-flow CAPEX is not published, which is why it leads here.

This conclusion weakens if: Net debt rises faster than revenue and profit for two consecutive reported periods.
Gross debt shows contractual borrowings. Net debt subtracts reported cash; a negative value means net cash. Lower debt can create capacity, but should be read against the scale and capital intensity of the business.

PEG is shown only when earnings are positive and three-year EPS growth is between 5% and 60%. It is recomputed consistently as the trailing P/E divided by that growth rate — reported earnings, never an expected-earnings multiple. On Indian companies it is shown only where the two data sources reconciled. A missing PEG is more honest than a low-base fiction.

What can make this comparison misleading?
This Pollution & Treatment Controls comparison names 5 specific ways its own evidence can mislead, all listed below. All 7 companies here report on comparable dates, so no rank carries a stale marker. 1 of the 8 ranked sections has fewer than three usable current readings. A high growth rate can still be a low-base artefact.
Keep these limits visible
A high growth rate can be a low-base artefact. The page keeps level and change separate for that reason.
A high ROCE can be temporary or flattered by a small capital base. Read it beside margin, cash conversion and reinvestment.
The 4-Factor Sector Score ranks research priority, not portfolio action. Management quality, catalysts and risks need equally fresh evidence before capital is deployed.
An “all companies” line chart preserves completeness, but rank changes should be checked against reporting dates before drawing a conclusion.
Thin comparisons: Valuation have fewer than three usable current readings.

The charts above default to a selective view; this register is the complete set, with each company's own latest reporting date beside it.
AHEAD means the company is beating the index by 5% or more over three months. LAGGING, FUNDAMENTALS UP means it is 20% or more behind over a year while its trailing twelve-month earnings grew 20% or more. Both rules are fixed and applied the same way in every sector.
This comparison is built from the reported filings of 7 Pollution & Treatment Controls companies, normalized to a common $ scale and a shared quarter axis of up to 20 quarters each. Fundamentals run through Jun 2026 and market data through 2026-07-28. A second data feed fills gaps only after identity and scale reconciliation, and missing observations are never interpolated.

Pollution & Treatment Controls company comparison FAQs
These 17 answers restate the Pollution & Treatment Controls comparison above in question form. Every one is computed from the same 7 companies and the same reported filings as the rankings and charts, current through Jun 2026. Price and relative-strength answers run through 2026-07-28. Nothing here is estimated, and none of it is a recommendation.
Which Pollution & Treatment Controls company is the biggest?
Zurn Elkay Water Solutions Corporation is the largest, with trailing-twelve-month revenue of $1,740 million, ahead of CECO Environmental Corp. at $804 million. That covers 5 of 7 companies with comparable reporting through Mar 2026.
Which Pollution & Treatment Controls company is growing fastest?
CleanCore Solutions, Inc. has the fastest revenue growth at 100% year on year, across 4 of 7 comparable companies. Fast growth off a small base is not the same as proven scale — check whether the rate holds across several quarters on the chart above before treating it as a trend.
Which Pollution & Treatment Controls company has the best profit margins?
Veralto Corporation has the highest operating margin at 23.8%, from 4 of 7 comparable companies. Aduro Clean Technologies Inc. shows the biggest recent improvement, at +3610.8 percentage points. A high margin matters most when it is holding or rising, not when it is peaking.
Which Pollution & Treatment Controls company makes the most profit?
Zurn Elkay Water Solutions Corporation earns the most, at $211 million of trailing-twelve-month net profit, from 6 of 7 comparable companies. Zurn Elkay Water Solutions Corporation has the fastest profit growth at 27.1%, though growth off a small or recovering profit base overstates how much has actually changed.
Which Pollution & Treatment Controls company earns the highest return on capital?
Veralto Corporation leads on return on capital employed at 6.1%, across 7 of 7 companies. Read it beside the length of its reported history: a high return that repeats for years is evidence of a durable business, while a single high reading can be a small capital base or one good year.
Which Pollution & Treatment Controls stock is the cheapest?
On guarded PEG — where a LOWER number is cheaper — Zurn Elkay Water Solutions Corporation screens cheapest at 1.36×. Only 2 of 7 companies pass the comparability guard, so this is not a sector-wide "cheapest stock" verdict. Cheap on a multiple is a reason to investigate, never a reason to buy on its own.
Which Pollution & Treatment Controls company has the strongest balance sheet?
Aduro Clean Technologies Inc. carries the lowest comparable gross debt at $0 million, from 7 of 7 companies. Absolute rupee debt alone does not settle it, because company scale differs — net debt and debt-to-equity in the chart above carry more information, and a very low-debt balance sheet can also mean under-investment.
Which Pollution & Treatment Controls company is investing most in new capacity?
Veralto Corporation reports the largest capital spending at $12 million, across 7 of 7 companies. Spending consumes cash before it earns anything, so treat the ranking as a diligence queue: check commissioning, utilisation and the return earned on the completed assets before reading spend as value creation.
Is the Pollution & Treatment Controls sector beating the market?
Pollution & Treatment Controls has underperformed S&P 500 by 20.1% over the last 52 weeks and 8.7% over 13 weeks, measured on an equal-weight index of its current members. Inside the sector, 0 of 7 covered companies are beating the market on their own. Sector strength does not transfer evenly to every stock in it.
Which Pollution & Treatment Controls stock has the strongest price momentum?
CECO Environmental Corp. has the strongest relative strength against S&P 500. Relative strength answers last, after growth, quality and valuation: price can move well before the fundamentals confirm it, and sometimes without them confirming at all.
Which Pollution & Treatment Controls company scores highest for research priority?
Zurn Elkay Water Solutions Corporation scores 60.8 out of 100 with 79% evidence confidence, from 24.3 points on growth and earnings, 15.8 on capital efficiency, 11.7 on valuation and 9 on relative strength.
