The TecDAX stock index tracks the performance of the 30 largest German companies from the technology sector. In terms of order book turnover and market capitalization the companies rank below those included in the DAX.

The TecDax was introduced on 24 March 2003. It succeeded the NEMAX50 (Neuer Markt — new market) stock index of German new economy companies that existed from 1997 to 2003 and was discontinued after extreme value loss due to the burst of the dot-com bubble.

TecDAX is based on prices generated in Xetra. The index is calculated on every trading day, between 9am and 5.30pm CET .


The following 30 companies make up the index as of the quarterly review effective 19 September 2011, which saw PSI and XING replace Phoenix Solar and Roth & Rau.[1] The index was left unchanged at the quarterly review of December 2011.
