The DAX is a stock market index consisting of the 40 major German blue chip companies trading on the Frankfurt Stock Exchange. It is a total return index. Prices are taken from the Xetra trading venue. According to Deutsche Börse, the operator of Xetra, DAX measures the performance of the Prime Standard's 40 largest German companies in terms of order book volume and market capitalization. DAX is the equivalent of the UK FTSE 100 and the US Dow Jones Industrial Average, and because of its small company selection it does not necessarily represent the vitality of the German economy as a whole.
