DAX Index Review Frequency and Historical Constituents

Summary

The document answers two practical questions about DAX constituent weights: how often index composition is reviewed and where historical weights can be found. It says an exchange committee reviews the composition quarterly, while changes are relatively infrequent. It also points readers to the DAX index provider’s composition spreadsheets for current and past weights.

The historical data described only extends back to 2009, which limits longer-term constituent or weight analysis. The source gives no details on the index’s weighting methodology, exact effective dates, or a downloadable dataset within the text. Researchers using the data should therefore verify the provider’s records and coverage before relying on them for historical portfolio reconstruction or backtests.

Key ideas

• A committee reviews DAX index composition quarterly.
• Constituent changes are described as relatively infrequent.
• Composition spreadsheets from the index provider contain current and historical weights.
• The cited historical coverage extends back only to 2009.
• The document does not explain the DAX weighting methodology or provide detailed effective dates.

A committee at the exchange reviews the composition of the DAX quarterly. In practice there are relatively few and infrequent changes. Current and past weights are given here dax-indices.com/EN/index.aspx?pageID=4 , but the old data only goes back to 2009. Look for spreadsheet files called "Composition DAX".
