Rank-Adjusted Weight is a metric that recalibrates the portfolio or holding weight of securities according to their relative ranking within a given Investment Theme. Rather than treating all securities equally, this measure provides a more precise representation of a portfolio's effective thematic exposure by attributing greater weight to higher-ranked securities β those most central to the theme β while proportionally discounting lower-ranked securities that maintain a more peripheral association with the theme.
