Does the ∆P index change over time compared to its value at the current moment?
Yes, it is possible. The ∆P index is the result of the currently available information. If some incoming data are delayed or changed, we make a recalculation then it is available, and annual subscribers get an updated ∆P index value with the following report. From our experience, it could cause minor changes in the ∆P index value, because economic processes have inertia.
