Direct Answer
The Dow Jones Industrial Average is a rule-based measurement of 30 u.s. blue-chip companies; price weighted, maintained by S&P Dow Jones Indices. 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 Dow Jones Industrial Average covers 30 u.s. blue-chip companies; price weighted, within the United States market. S&P Dow Jones Indices 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 S&P Dow Jones Indices's current methodology document, so none is stated here rather than guessed. The provider link below is authoritative.
