Direct Answer
The SEMDEX is a rule-based measurement of all companies listed on the official market of the stock exchange of mauritius, maintained by Stock Exchange of Mauritius. 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 SEMDEX covers all companies listed on the official market of the stock exchange of mauritius, within the Mauritius market. Stock Exchange of Mauritius defines which securities are eligible, how they are selected from that pool, and how much each one contributes to the published number.
The index name does not state a fixed company count, so the number of constituents follows the eligibility rules rather than a target.
How constituents are weighted
Swoopr has not verified the weighting method for this index against Stock Exchange of Mauritius's current methodology document, so none is stated here rather than guessed. The provider link below is authoritative.
Current SEMDEX constituents
Stock Exchange of Mauritius publishes and licenses the SEMDEX constituent list. Swoopr does not republish it here. The provider's own page is the authoritative source for current membership and weights.
