# KOSPI: What It Measures and How It Is Built







## Direct Answer



> The KOSPI is a rule-based measurement of main korean stock-market benchmark, maintained by Korea 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 KOSPI covers main korean stock-market benchmark, within the South Korea market. Korea Exchange 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 Korea Exchange's current methodology document, so none is stated here rather than guessed. The provider link below is authoritative.








## Current KOSPI constituents



Korea Exchange publishes and licenses the KOSPI constituent list. Swoopr does not republish it here. The provider's own page is the authoritative source for current membership and weights.
