Direct Answer
The KOSPI 50 is a rule-based measurement of korean large-cap equity 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 50 covers korean large-cap equity 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 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.
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 50 constituents
