Weight: total market value of the sector's companies over the index total, without S&P's float adjustment (indicative). Companies with two share classes count once. The classification is the market-data provider's (Yahoo Finance), similar to but not the same as GICS: packaging makers, for instance, sit in consumer cyclical here.
The "best rank" is the sector's first company in the order a quantitative model produces today (data as of Sep 18, 2026). It is a calculation on public data, not a recommendation to buy or sell, and the portfolios built with it have simulated returns. How it is computed: see the methodology.
