The DAX 30 Stock Market Index (full name the Deutscher Aktien IndeX, which means German Stock Index) consists of 30 large, blue-chip German companies trading on the Frankfurt Stock Exchange.
Just like the FTSE 100 and S&P500 it is a capitalization-weighted index so it essentially measures the performance of the 30 largest, publicly traded companies in Germany. It is therefore a strong indicator of the strength of the German economy and investor sentiment towards German equities.
Companies that Make Up the DAX 30 Stock Market Index
