Direct Answer
The MT30 Index is a rule-based measurement of top 30 companies listed on the saudi exchange weighted by free-float market capitalisation, maintained by Saudi 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 MT30 Index covers top 30 companies listed on the saudi exchange weighted by free-float market capitalisation, within the Saudi Arabia market. Saudi 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 30 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 Saudi Exchange's current methodology document, so none is stated here rather than guessed. The provider link below is authoritative.
Current MT30 Index constituents
Saudi Exchange publishes and licenses the MT30 Index constituent list. Swoopr does not republish it here. The provider's own page is the authoritative source for current membership and weights.
