RCTR is passively managed to track an index of companies with significant revenue exposure to nuclear-related activities. Companies must operate in at least one of three nuclear ecosystem categories: power generation (nuclear plant operators), Uranium (miners/enrichers), or equipment and engineering (nuclear plant/technology services). An evaluation of operational and financial factors like production scalability, capital allocation, customer relationships, and capital access are considered. Companies are scored and placed in one of three tiers based on revenue and thematic assessments. Only the top tier firms, meeting free float and liquidity thresholds, are eligible. The top 50 names by revenue and market-cap are included, with weights adjusted by revenue assessment and capped at 4.5%. The index is rebalanced quarterly.
