Review (indices)

Mathematical method used to ensure the consistency of an index when the index is given a new weighting, or when there are changes to its composition

On the third Friday in the last month of the quarter (March, June, September, December), Deutsche Börse AG reviews its indices. In the review process, the variables used in calculating the index are adapted to the current composition of the index. For example, adjustment factors, changes to the capital stock, and dividend payments that took place between review dates are given a value of one in the index formula. To ensure consistency, the newly calculated index values are multiplied by a review factor. Reviews are conducted using the Xetra® closing prices on the review date.
