The KOF Economic Barometer is a composite leading indicator for the Swiss economy. Monthly from January 1991.
The KOF economic barometer is an index that (as of 2017) is sythesized from over 200 indicator variables selected from a pool of more than 500 candidates. Every year the source may choose to change the composition and weighting of the index. The chosen variables best meet these two criteria: They (a) have an economically plausible influence and (b) have a certain lead time of a relevant strength over the economic trend.
Each year, after release of GDP, the source produces a new vintage of the Barometer. After redefining its components, the Barometer is recomputed and full revised history is published.
