Definitions

In plain terms

It may hold every constituent in index weights or use a representative sample when full replication is costly or impossible.

Technical

The design requires target index and variant, holdings and cash, prices, corporate actions, rebalances, constraints, sampling, costs, taxes, lending, and tracking measurement.

Scope

The index itself is a calculation; a replication portfolio has implementation frictions and can diverge.

Examples

  • A governed methodology records replication portfolio with its source, cutoff, units, parameters, and effective version.

Common misconceptions

  • Replication Portfolio does not have one universal implementation without the declared methodology, data basis, and constraints.

    Supports: variant distinction

    Limits: Defines governed platform behavior rather than claiming these policies are universally prescribed by external McClellan methodology.
