SDAX Index components | values (DE0009653386)

The SDAX (derived from Small-Cap-DAX) is a German share index that was introduced by Deutsche Börse AG on June 21, 1999. It is the selection index for 70 smaller companies, so-called small caps, which follow the values ​​contained in the MDAX in terms of trading volume and market capitalization. The 165/165 rule applies here, which means that only listed companies that, according to these criteria, are among the 165 largest stocks listed in the Prime Standard can be included. The same criteria apply for exclusion from the SDAX if they are missed for a long time or by a large margin. The value selection is checked quarterly at the beginning of March, June, September and December.


The basic rating of the SDAX is December 30, 1987 with a value of 1000 points.


Until June 24, 2002 (see web link for historical index composition) the SDAX contained the 100 most important small caps. In the course of the index redesign, it was reduced to 50 values ​​in March 2003. In September 2018, the SDAX was expanded to 70 stocks in order to also include some of the stocks previously exclusively listed in the TecDAX.


In addition to the DAX, TecDAX and MDAX, the SDAX is part of the Prime Standard and the DAX index family.


The SDAX is based on the prices of the electronic trading system Xetra. Its calculation begins every trading day at 9:00 a.m. CET and ends with the prices from the Xetra closing auction, which starts at 5:30 p.m. CET. Deutsche Börse calculates the L-SDAX between 5:45 p.m. and 8:00 p.m. CET. This so-called “late index” is an indicator of the performance of German small caps after the end of Xetra trading.
