Toward S means a higher total-score band; toward F, a lower band. Badges are distinguished by ink intensity and shape (fill, outline, dashed) — never by hue.

Maegim maps a total score — built from sector-relative percentile scoring — onto fixed, predefined thresholds to assign one of six bands, S to F. This stock is scored by the same formula as all 2,523 graded stocks and is currently in band F with a total score of 13.5 points.
