# VN30 Index: What It Measures and How It Is Built

## Direct Answer

> The VN30 Index is a rule-based measurement of Vietnamese blue-chip equity benchmark, maintained by HOSE/HNX. Like every index it owns nothing: it is a number produced by applying a published weighting formula to a selected list of companies, revised on a schedule the provider sets.

## What this index covers

The VN30 Index covers Vietnamese blue-chip equity benchmark, within the Vietnam market. HOSE/HNX defines which securities are eligible, how they are selected from that pool, and how much each one contributes to the published number.

The name states a target of 30 companies. A target is not a guarantee of the exact count on any given day: corporate actions, dual share classes and pending additions all move the real number around it.

## How constituents are weighted

Swoopr has not verified the weighting method for this index against HOSE/HNX's current methodology document, so none is stated here rather than guessed. The provider link below is authoritative.

## Current VN30 Index constituents

HOSE/HNX publishes and licenses the VN30 Index constituent list. Swoopr does not republish it here. The provider's own page is the authoritative source for current membership and weights.
