DAX 30
A German stock index made up of 30 blue chip stocks. Like the S&P500, the CAC-40 and the FTSE 100 it is a market-value weighted index. Unlike these other indices, which only measure change in market prices, the DAX attempts to measure changes in the total return of its constituents. The DAX takes account of dividend income and notionally reinvests any dividend income in additional shares of the company concerned in the same proportion as their weighting index. Even if there is no change in German share prices it is possible for the DAX to rise because an inflow of dividend income. Futures and options contracts on the DAX 30 are listed on the EUREX exchange.
