Composite PMI (The Cumulative PMI Index) reflects the monthly weighted average dynamics of two PMI indexes: service sectors and industry. The weight of each of the indices is taken into account on the basis of official data on GDP. The index assumes a value from 0 to 100. Values above 50 mean an increase in business activity compared to previous month. The index takes into account seasonal adjustments. Typically, the data on the results of the month are published at the end of the first working week of the next month.
