Index Weight
Constituent weight data for major indices, spanning the CSI 300, MSCI, FTSE and other index families, giving each member stock's weight within a given rebalancing period. It is used to track index reconstitutions, estimate passive-fund indexing flows, and build benchmark or index-replication portfolios. Typically updated monthly with weights expressed as percentages; data shifts notably around effective rebalancing dates, so query by constituent period.
