The DAX, or Deutscher Aktienindex, is a stock market index that comprises 30 of the largest and most liquid German companies trading on the Frankfurt Stock Exchange. It is a critical benchmark for Germany’s economy and an important indicator for the European markets.
Types

Detailed Explanation
The DAX index uses a free-float market capitalization-weighted methodology. This means that companies with a higher market value have a more significant influence on the index’s movement.
The DAX is calculated using the following formula:
$$ \text{DAX} = \frac{\sum_{i=1}^{n} (P_i \cdot Q_i \cdot F_i)}{\text{Index Divisor}} $$
Where:
- \( P_i \) = Price of stock \( i \)
- \( Q_i \) = Number of shares of stock \( i \)
- \( F_i \) = Free float factor of stock \( i \)
- \( n \) = Number of companies in the index
