Direct Answer
The SET50 Index is a rule-based measurement of thai blue-chip equity benchmark, maintained by Stock Exchange of Thailand. 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 SET50 Index covers thai blue-chip equity benchmark, within the Thailand market. Stock Exchange of Thailand 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 50 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.

Swoopr has not verified the weighting method for this index against Stock Exchange of Thailand's current methodology document, so none is stated here rather than guessed. The provider link below is authoritative.
