Direct Answer
The NSE 20 Share Index is a rule-based measurement of top 20 companies listed on the nairobi securities exchange by market activity, maintained by Nairobi Securities 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 NSE 20 Share Index covers top 20 companies listed on the nairobi securities exchange by market activity, within the Kenya market. Nairobi Securities 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 20 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 Nairobi Securities Exchange's current methodology document, so none is stated here rather than guessed. The provider link below is authoritative.
