Direct Answer
The MSCI World IMI is a rule-based measurement of large-, mid-, and small-cap equities across 23 developed market countries worldwide, maintained by MSCI. 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 MSCI World IMI covers large-, mid-, and small-cap equities across 23 developed market countries worldwide, within the Global market. MSCI 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 MSCI's current methodology document, so none is stated here rather than guessed. The provider link below is authoritative.
Current MSCI World IMI constituents
