The 0–100 composite combines relative strength (30%), momentum (20%), volume (15%), ETF weight (15%), node correlation (5%), new inclusion (5%) and short-squeeze positioning (10%). It is not a return forecast or a pure relative-strength ranking. A dash means data is unavailable, not zero.
Business roles are separate from the site's screening rules. ETF inclusion or pension-fund ownership does not establish a company's product mix. Source-backed notes below explain our classification; they do not quantify revenue exposure or recommend a trade.
