The ISM Services PMI is a composite index consisting of four equally weighted diffusion indexes: Business Activity, New Orders, Employment, and Supplier Deliveries. A reading above 50 indicates expansion in the services sector, while below 50 suggests contraction. Supplier Deliveries is the only ISM index that is inversed; a reading above 50 indicates slower deliveries.

The ISM figures are available in Haver's USECON database, with additional detail in the SURVEYS database. The expectations figure from Action Economics is in the AS1REPNA database.
