Direct Answer
The BGBX40 is a rule-based measurement of bulgarian large-cap equity benchmark, maintained by Bulgarian Stock Exchange. Like every index it owns nothing: it is a number produced by applying a published weighting formula to a selected list of companies, revised on a schedule the provider sets.
What this index covers
The BGBX40 covers bulgarian large-cap equity benchmark, within the Bulgaria market. Bulgarian Stock Exchange defines which securities are eligible, how they are selected from that pool, and how much each one contributes to the published number.
The name states a target of 40 companies. A target is not a guarantee of the exact count on any given day: corporate actions, dual share classes and pending additions all move the real number around it.
How constituents are weighted
Swoopr has not verified the weighting method for this index against Bulgarian Stock Exchange's current methodology document, so none is stated here rather than guessed. The provider link below is authoritative.
Current BGBX40 constituents
Bulgarian Stock Exchange publishes and licenses the BGBX40 constituent list. Swoopr does not republish it here. The provider's own page is the authoritative source for current membership and weights.
