# SET Index: What It Measures and How It Is Built







## Direct Answer



> The SET Index is a rule-based measurement of broad thai 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 SET Index covers broad thai 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 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 Thailand's current methodology document, so none is stated here rather than guessed. The provider link below is authoritative.








## Current SET Index constituents



Stock Exchange of Thailand publishes and licenses the SET Index constituent list. Swoopr does not republish it here. The provider's own page is the authoritative source for current membership and weights.
