Read a PMI as a survey indicator

Purchasing managers indexes collect business responses about changes in activity. TradingPedia’s PMI lesson introduces a composite survey indicator and discusses components such as production, orders, employment and inventories. The result differs from a direct count of everything produced across the economy.

Check the named survey provider and sector, then read how its index is constructed. A manufacturing survey and a services survey cover different businesses. Distinguish a preliminary estimate from a final result and retain the reporting month. When a survey uses 50 as its no change threshold, a number above that level refers to the survey’s comparison basis; it does not mean the economy grew by that percentage. Use components and accompanying commentary to understand the headline, without treating the survey as a certain trading signal.
