Definition of the Purchasing Managers’ Index (PMI)
The Purchasing Managers’ Index (PMI) is a key economic indicator that shows the prevailing direction of economic trends in both the manufacturing and service sectors. Compiled monthly by the Institute for Supply Management (ISM), this diffusion index helps gauge whether the overall market conditions are expanding, stable, or contracting, as perceived through the lens of purchasing managers. Think of PMI as the economic heartbeat—pulsating to give a signal about where the economy might be heading!

- Production
- Employment
- Supplier Deliveries
