Index Description

SDAX tracks the performance of German small-sized companies, so called small caps. The SDAX contains 70 companies listed on the Regulated Market of Frankfurter Wertpapierboerse (FWB, the Frankfurt Stock Exchange), which fulfill certain quality requirements and follow the 40 DAX companies and 50 MDAX companies in terms of free float market capitalization. Similar to DAX, the SDAX is primarily calculated as a performance index, thus fully reflecting the actual performance of an investment in the index portfolio.

Key facts

  • SDAX is the defining index for German small caps, it serves as underlying for financial products (options, futures, ETFs, structured products) and for benchmarking purposes
  • Index calculation and index composition is determined on the basis of a clear and publicly available set of rules.
  • To be eligible for index inclusion, companies must fulfill a set of basic criteria. The selection of index components is based on free float market capitalization.
  • The index composition is reviewed quarterly in March, June, September and December.
  • Index components are capped at a maximum weight of 15% on a quarterly basis.

A company that is already an index component must have a minimum order book volume over the last 12 months of at least 0.8 bn EUR or show a turnover rate of 10% at monthly selection list cut-off date in order to remain in the index. The selection of index components is based on free float market capitalization.
