PMI as Leading Economic Activity Indicator

Purchasing Managers' Index surveys are the most reliable leading economic indicators available in real time.

They are released monthly within the first week and are not revised, making them highly tradeable.

The 50-level threshold distinguishes expansion from contraction.

But the trajectory and rate of change matter more than the absolute level:

A PMI rising from 48 to 49 can be more bullish than one falling from 54 to 53.

Manufacturing PMI leads the business cycle, while Services PMI is more resilient (services represent 70-80% of developed economies).

Their divergence — "bifurcated economy" — has been a structural feature post-2022:

Manufacturing in contraction while services expand.

Global PMI aggregates (JP Morgan Global Composite) provide cross-asset regime context.

Synchronized global PMI contraction historically precedes equities drawdowns; synchronized expansion supports risk-on positioning.

New Orders sub-index is the most forward-looking component within PMI, leading the headline by 1-2 months. **Examples:

** 2015–2016 — Global markets:

JP Morgan Global Manufacturing PMI fell below 50 for 8 consecutive months → industrial metals declined 25% (copper:

-30%), emerging market equities underperformed developed markets by 15% over the period, and global growth stocks underperformed defensives. **Example 2:

** 2020–2021 — Global markets:

Global Composite PMI collapsed to 26.6 in April 2020 then recovered to 58.5 by May 2021 — the sharpest expansion in survey history → commodity-linked assets led recoveries; copper rose 90% in 12 months; cyclical equities outperformed defensives by 35%.
