How is this ranking built?

Every industry list applies the same steps at its own cutoff: industry membership, the latest AI report rating on or before the cutoff, a report age limit, dated market data, then a sort by rating with ties ordered by ticker. The animation steps through them with one real example, the live cybersecurity list refreshed on October 13, 2026.

A live list's cutoff is its refresh time. A past year's list uses December 31 of the year before, and the current year's list uses the time it was generated. A Top N page shows the first N rows of its year's list and exists only when that list has at least N companies.

What best means in this list

This list was refreshed on 2026-11-07 using existing company reports. The report date in each row is the date of the underlying analysis; refreshing the list does not create a new company report.

Best means the highest stored NexusTrade report ratings within this selection. Ratings use the product's 1-to-5 scale. The list sorts by rating from high to low, with ticker order breaking equal-rating ties. A rating summarizes a report; it does not predict a stock's return.

Companies belong to the Clean Energy classification, based on company products and revenue. Classifications can overlap, so a company may appear in several industry lists.

What the leading companies do

The first 5 companies below lead the ratings in this snapshot; equal ratings are ordered by ticker. Their company profiles describe different businesses even when they share the Clean Energy selection.

These are company descriptions, not estimates of revenue from this theme. Industry membership does not identify a pure-play business or establish how much sales depend on it. Open the company profile and examine segment disclosures before treating an overlapping classification as equivalent exposure.

Valuation and company size within this selection

These summaries use the 238 displayed companies. Each company retains its own market observation date in the ratings table above. Medians are unweighted; they are not a sector index valuation.

Positive P/E and price-to-book values are summarized separately. Missing, zero and negative values are excluded from those medians, with the included count shown. A lower multiple alone does not establish better value: profitability, growth, debt and business mix can differ.

Other business classifications in the list

A company can appear in several product and revenue classifications. These overlapping memberships help identify different business mixes to investigate; they are not verified revenue shares or mutually exclusive subindustries.

Dates and coverage

Report dates range from 2025-12-31 to 2026-10-15. Market observations range from 2026-11-06 to 2026-11-06. These dates may differ across companies. Daily closes are not synchronized live quotes.

The selection includes 4 companies without a report, 0 with invalid latest rating metadata, 0 with older reports, 5 with missing required fundamentals and 0 with out-of-date market observations. Missing companies receive no substitute score.

How the ranking is built

The ranking uses the latest stored report at or before the refresh cutoff for each active eligible company. The report date, fiscal year/period and producing model remain visible. The latest invalid score is excluded; an older favorable score does not replace it. Publication policy stock-ratings-v1 accepts report ages up to 550 days and market observations up to 10 calendar days, with a positive close and market capitalization. Optional missing ratios remain not reported.

Report ages can differ substantially, particularly between annual and quarterly reports. Different producing models may also use different judgments. Read the date, fiscal period and model before comparing scores. Private report analysis and account data are not published here.

A refresh reads existing reports and market data. It does not rerun a model or create a new analysis. Compare business fundamentals and your own research constraints alongside the score before making a decision.
