Index Description

The STOXX Global and Country blue-chip indices are fixed-number indices designed to represent the largest components by free-float market cap of their geographic region defined by the relevant benchmark indices.

Key facts

  • Liquid indices, as they cover about 60% of the free-float market cap of the relevant benchmark index
  • The indices are diversified, as they incorporate a capping factor to ensure that no country/component can dominate the index
  • Buffers are used to achieve the fixed number of components and to maintain stability of the indices by reducing index composition changes

Methodology

The index universe is the relevant benchmark index. To be eligible for inclusion, the three-month average daily trading volume (3-month ADTV) has to be at least 1 million euros. Components are selected on the basis of the free-float market cap and a 10% buffer rule applies for the ranking. If the number of stocks selected is still below the required component count after applying the buffer rules, the largest remaining stocks are selected until there are enough stocks. The detailed methodology including the calculation formula can be found in our rulebook: http://www.stoxx.com/indices/rulebooks.html
