Direct Answer
The Nasdaq Composite is a rule-based measurement of nasdaq-listed common-type stocks, maintained by Nasdaq. 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 Nasdaq Composite covers nasdaq-listed common-type stocks, within the United States market. Nasdaq 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 Nasdaq's current methodology document, so none is stated here rather than guessed. The provider link below is authoritative.
Current Nasdaq Composite constituents
Nasdaq publishes and licenses the Nasdaq Composite constituent list. Swoopr does not republish it here. The provider's own page is the authoritative source for current membership and weights.
