The Deutscher Aktien Index, or DAX 30 for short, is the blue chip market index for the Frankfurt Stock Exchange. It follows the top 30 german stocks on the electronic Xetra system that is used on the exchange.

Weighting and Calculation

The DAX indices are all calculated using capitalization weighted index using the total return Laspeyres index for calculations^[1].

DAX Indices are weighted by shares.

• The formula is:

Current index = Current total market cap of constituents × Previous Value / Previous Period

In comparison, the Shanghai SSE indices use the Paasche weighted composite price index formula^[2]. This means that the index is bases its calculations on its previous period for its calculations as compared to the Shanghai Composite Index, which bases it on the base period.

The Base date for the index is 30 December, 1987 and it was started from a base value of 1,000. The Xetra system calculates the index after every 1 minute.^[3]
