Calculate your own indices

You calculate your own indices in the Infront Portfolio Manager by assigning the option "Index composition" to securities of the type "Index" in the quote properties. You select the composition of the index individually.

For the index calculation (without rebasing), the security prices (after factor adjustment and currency conversion) are multiplied by the respective weights. These values are then added up for all securities. The result is divided by the base factor, which gives the index price.

A price is calculated for the index for the days on which a price exists for at least one index participant. This also applies in particular to index calculations with rebasing.
