# S&P/BMV IPC CompMX: What It Measures and How It Is Built

## Direct Answer

> The S&P/BMV IPC CompMX is a rule-based measurement of an extended universe of Mexican equities listed on the BMV beyond the core IPC, maintained by S&P Dow Jones Indices. Like every index it owns nothing: it is a number produced by applying a published weighting formula to a selected list of securities, revised on a schedule the provider sets.

## What this index covers

The S&P/BMV IPC CompMX covers an extended universe of Mexican equities listed on the BMV beyond the core IPC. S&P Dow Jones Indices defines which securities are eligible, how they are selected from that pool, and how much each one contributes to the published number.

The methodology document, published by S&P Dow Jones Indices, sets the rules for inclusion and removal. Corporate actions, index reviews, and eligibility changes all move the constituent list on the timetable the provider specifies.

## How constituents are weighted

Swoopr has not verified the weighting method for this index against S&P Dow Jones Indices's current methodology document, so none is stated here rather than guessed. The provider link below is authoritative.

## Current S&P/BMV IPC CompMX constituents

S&P Dow Jones Indices publishes and licenses the S&P/BMV IPC CompMX constituent list. Swoopr does not republish it here. The provider's own page is the authoritative source for current membership and weights.
