03 · Prism readout

What the signals say—and what they do not

The headline share is normalized water supply news attention across these five names. Partial community coverage and U.S.-scope patent records are displayed separately and are not blended into it.

Scale + attention

American Water leads the conversation

It holds 71.9% of measured water supply news attention and also carries the basket's largest revenue base at $5.12B.

Price path

SJW Group leads the available price paths

Its monthly-close return is -4.0% for the five-year window. At the other end, Middlesex Water is -43.7% for its five-year window. Windows printed on each card must be compared carefully; price history is not a forecast.

Profitability

Middlesex Water has the widest latest margin

Its FY2024 net margin is 23.1%. Its revenue history in this snapshot spans only the periods printed on its card, so longer histories are not treated as equivalent.

Price vs operating signals

Artesian Resources shows why one ratio is not a verdict

It has the basket's lowest snapshot P/E at 15.7x while its five-year window price return is -6.3%. Valuation, price path and readiness answer different questions.

How to read this snapshot

Basket and ranking

Five currently eligible U.S.-listed issuers classified under SEC SIC 4941 (Water Supply). The builder rechecks price, filing and Prism evidence before assembling the basket. This is a focused research comparison, not a complete sector index.

Companies are ordered by the Fliar BI Prism readiness score used by the Prism Finance USA source pack. The score is a research signal, not a recommendation.

Evidence used

  • Official annual filingsFY revenue history and latest profitability
  • U.S. exchange market snapshotDated price, 52-week range, P/E, market capitalisation and monthly-close return

Conclusions
Comparisons
Anomalies

Middlesex Water shows a price-operating divergence to inspect

Its displayed filing-revenue change is +35.6% while its available monthly-close return is -43.7%. The signs differ, but the two measures cover different windows and do not establish causality.

Open Middlesex Water in Companies Radar
Explanations

Attention measures coverage volume, not quality

American Water's 71.9% share says it appears most often in the matched Prism corpus. It does not score whether that coverage is favourable or whether the company is investable.

Open American Water in Companies Radar

Different windows explain why signals can disagree

Revenue comes from the printed filing periods, price paths use the dated monthly-close windows, and Prism signals use their stated event windows. No causal attribution is made across them.
