Purchasing Managers’ Index surveys provide timely evidence about business activity. Traders compare the result with forecasts, the prior month, and the internal components rather than using the 50 threshold alone.
Expansion and contraction
A reading above 50 generally indicates expansion and below 50 contraction, but the rate of change matters. A reading can remain below 50 while improving significantly.
Manufacturing versus services
The relative importance of each survey depends on the economy. Services can carry more weight where it represents a larger share of activity.
Read prices and employment
Input prices, output prices, new orders, and employment can affect inflation and growth expectations beyond the headline index.
Watch preliminary and final releases
Flash estimates often create the larger reaction because they are the first signal. Final values can still matter when revisions are substantial.
Preparation checklist
- Identify flash or final data
- Compare with forecast and prior
- Read key subindexes
- Map the relevant currency
- Wait for market confirmation
