Signals ยท Manufacturing pulse
Which signals lead, which follow.
A lead-lag correlation study of U.S. manufacturing signals, computed from five years of monthly changes: which indicators move together, which lead which and
Signals tracked
- 9 monthly manufacturing indicators are correlated here: industrial production, factory orders, truck tonnage, housing starts, vehicle sales, job openings, steel ppi, copper ppi, prime rate.
- Every series is reduced to its month-over-month percent change before correlating, so a shared trend cannot manufacture a relationship.
Strongest co-movements
- Vehicle sales and Job openings move inversely (correlation -0.59).
- Industrial production and Vehicle sales move together (correlation 0.51).
- Housing starts and Copper PPI move together (correlation 0.39).
- Factory orders and Steel PPI move together (correlation 0.39).
- Job openings and Copper PPI move together (correlation 0.34).
- Industrial production and Copper PPI move inversely (correlation -0.32).
- Job openings and Steel PPI move together (correlation 0.28).
- Housing starts and Vehicle sales move together (correlation 0.28).
Methodology
- Correlations are ordinary Pearson coefficients over the months two series have in common; a pair needs at least a year of overlap to appear.
- The interactive page also scans one-to-six-month lags to rank which signals lead which, and publishes each series' out-of-sample forecast accuracy. These are statistical tendencies, not causal claims.
