Explained on 26 October 2026. This is an educational answer drawn from the dated article below; examples are hypothetical unless a specific source observation is identified.
How it works
Each measure answers a different question: benchmark representation, portfolio concentration or ownership stake. A fund can hold a meaningful portfolio weight while owning a small fraction of a large company. Do not compare percentages until their bases are named and the dates align.
A simple example
A hypothetical stock is 2% of an index, 1% of a scheme and represents a 0.05% company stake for that scheme. None of the figures contradicts the others. They use different denominators and cannot substitute for one another in an exposure calculation.
| Measure | Relevant base |
|---|---|
| Index weight | Benchmark value under its method |
| Fund weight | Scheme assets |
| Ownership | Company shares |
What to check
- Label the denominator next to every percentage.
- Use the scheme weight for look-through exposure.
- Use share counts and company shares for ownership.
