Definitions
In plain terms
With 20 constituents, each begins at a 5% target weight before market movements cause weights to drift.
Technical
The methodology must define rebalance dates, target population, pricing, share calculation, corporate-action handling, rounding, turnover, and treatment between rebalances.
Scope
Weights are equal only at the defined reset and can drift afterward.
Formula
w_i = 1 / Nw_i=1/N| Symbol | Meaning | Unit |
|---|---|---|
N | number of eligible constituents at rebalance | count |
Output unit: decimal weight
Examples
- A governed index record identifies equal-weighted index with its applicable methodology version, effective time, source, and units.
Common misconceptions
- Equal-Weighted Index does not have one universal implementation without the named index methodology, data cutoff, and governance context.
