Definitions
In plain terms
A leveraged, hedged, volatility-control, or decrement index starts from a particular underlying return variant.
Technical
Identity includes administrator, methodology and version, ticker or code, return variant, currency, calendar, dissemination source, correction policy, and licensing context.
Scope
The underlying name alone is insufficient when price, gross, net, or currency variants exist.
Examples
- A governed methodology records underlying index with its source, cutoff, units, parameters, and effective version.
Common misconceptions
- Underlying Index does not have one universal implementation without the declared methodology, data basis, and constraints.
