Direct Answer
The CAC All-Tradable is the widest French equity benchmark administered by Euronext, covering equities listed on both the regulated market and Euronext Growth Paris (the growth market). It extends beyond the CAC All Shares by including growth-market listings, making it the broadest representation of French-listed companies in the CAC family.
What this index covers
The CAC All-Tradable covers the France equity market through the Euronext Paris (regulated and growth markets). Euronext defines which securities are eligible, how they are selected from that pool and how much each contributes to the published number.
The eligible universe is: All equities listed on Euronext Paris regulated market and Euronext Growth Paris that meet the minimum eligibility criteria in the published Euronext index methodology.
Understanding the eligible universe is the most important step in understanding what an index measures. An index that selects by listing venue will behave differently from one that selects by company domicile, and a sector index will have very different risk characteristics from a broad market measure even if they share some constituents.
How constituents are weighted
Free-float-adjusted market-capitalisation weighting, per the Euronext published index methodology.
Weighting is the mechanism that translates a list of companies into a single number. Free-float-adjusted market-capitalisation weighting is the most common method: larger companies contribute more to the index level than smaller ones, and the free-float adjustment excludes shares that are not available to public investors (such as government-held strategic stakes or closely-held founder shares). This makes the index level reflect the actual investable market rather than total market size.
Eligible universe and eligibility rules
Eligibility rules determine which companies can be included at a review and which must exit. The key dimensions to verify are: which exchange or market segment is in scope; whether domicile or listing venue determines eligibility; the minimum free-float threshold; the liquidity screen; and whether there are sector restrictions.
For the CAC All-Tradable, the relevant market is the Euronext Paris (regulated and growth markets) and the administrator is Euronext. Per the published Euronext methodology (verification date: August 31, 2026), the eligible universe is defined as: All equities listed on Euronext Paris regulated market and Euronext Growth Paris that meet the minimum eligibility criteria in the published Euronext index methodology.
Reconstitution schedule
Quarterly, aligned with the Euronext CAC index family review schedule.
Reconstitution is the date on which the index changes shape by design rather than by price. Passive funds tracking the index must trade toward the new membership list, which creates predictable order flow around the review date. Active managers often position around reconstitution events to capture or avoid that flow.
How investors use this index
Widest-universe French equity reference; useful for research requiring coverage of growth-market companies not captured by regulated-market-only indexes such as CAC All Shares.
For any index, three uses are distinct: as a performance benchmark (measuring how well a portfolio did relative to the market), as a product underlying (an ETF or structured product replicating the index), and as a research reference (tracking market-cap, sector weights or concentration over time). The same index can serve all three purposes, but the choice of which to use depends on the investment mandate and the specific question being answered.
Comparisons with related indexes
The CAC All-Tradable is most often compared with:
- CAC All Shares: regulated market only; CAC All-Tradable adds growth-market listings.
- CAC 40: concentrated blue-chip benchmark; CAC All-Tradable covers the full spectrum including small growth-market companies.
When switching from one benchmark to another, the practical question is what changes in coverage: does the alternative add smaller companies, exclude a sector, change the weighting method or extend to a different currency? Each of these changes alters what the index can tell you about market performance.

Frequently Asked Questions
Who administers the CAC All-Tradable?
Euronext administers the CAC All-Tradable under its published CAC index family methodology.
What is the key difference between CAC All-Tradable and CAC All Shares?
CAC All-Tradable includes listings from Euronext Growth Paris (the growth market), while CAC All Shares covers only the regulated market. All-Tradable is therefore the broader of the two.
Are growth-market companies weighted the same way?
Weighting follows the same free-float-adjusted market-capitalisation methodology regardless of market segment. Growth-market companies are typically smaller and therefore carry lower weights.
How often is the CAC All-Tradable reconstituted?
Quarterly, on the same Euronext review schedule as the broader CAC family.
Where can I find current CAC All-Tradable data?
Euronext publishes index data on its official index pages. Swoopr links to the provider rather than reproducing licensed constituent lists.
