How the National Stock Indices works
Each market lists its main exchanges with local trading hours, its benchmark indices and the 25 largest constituents of the flagship index with ticker and GICS-style sector.
Most benchmarks are free-float market-capitalisation weighted, so the largest companies move the index the most. The Dow Jones Industrial Average and Nikkei 225 are notable exceptions that are price weighted.
Formulas used
- Cap-weighted index
level = Σ(price × free-float shares) ÷ divisor
