Quick Answer

PMI is a diffusion index built from surveys of purchasing managers and indicates the direction of business activity compared with the previous month. A reading above 50 generally signals an overall increase and below 50 an overall decrease. It is not a GDP growth rate or a forecast of stock-market returns.

Correct Interpretation and Practical Use

Start with the Core Point

PMIs may cover manufacturing, services or the whole economy, and their components and weights can differ. A reading of 52 does not mean the economy grew 2%, while 49 does not by itself confirm a recession. It summarises the direction and breadth reported by surveyed firms. One month can be affected by seasonality, delivery times and short-term events, so review the trend, sub-indices and other economic data.

How to Use This

Identify the PMI series, region and publisher first.
Review several months rather than one release.
Do not convert PMI directly into a stock-market trading signal.

Frequently Asked Questions

Does this method guarantee an outcome?

No. It is a tool for organising a decision, not a guarantee of returns, wealth or behavioural outcomes.

Should I rely on one number or rule?

No. At minimum, consider the goal, horizon, risk, cost, liquidity and date of the information together.
