The ISM Manufacturing survey for December 2012 rose into expansion territory after contracting last month. The sub-index which historically correlates to the economy barely shows expansion – and is unchanged month-over-month.
The ISM Manufacturing survey index (PMI) rose from 49.5 to 50.7 (50 separates manufacturing contraction and expansion). This was within expectations which were between 50.5 and 51.0.
This index has been in a general downtrend since mid 2011 – and the November data continued to confirm this.
Relatively deep penetration of this index below 50 has normally resulted in a recession.
The noisy Backlog of Orders rose significantly from 41.0 to 48.5 – but remains in contraction territory. Backlog growth is an indicator of improving conditions; a number below 50 indicates contraction. Backlog accuracy does not have a high correlation against actual data (although the last few month’s declines are proving marginally accurate).
Economic activity in the manufacturing sector expanded in December, following one month of contraction, and the overall economy grew for the 43rd consecutive month, say the nation’s supply executives in the latest Manufacturing ISM Report On Business®.
“The PMI™ registered 50.7 percent, an increase of 1.2 percentage points from November’s reading of 49.5 percent, indicating expansion in manufacturing for only the third time in the last seven months. This month’s PMI™ reading moved manufacturing off its low point for 2012 in November. The New Orders Index remained at 50.3 percent, the same rate as in November, indicating growth in new orders for the fourth consecutive month. The Production Index registered 52.6 percent, a decrease of 1.1 percentage points, indicating growth in production for the third consecutive month. The Employment Index registered 52.7 percent, an increase of 4.3 percentage points, indicating a resumption of growth in employment following only one month of contraction since September 2009. Both the Exports and Imports Indexes registered 51.5 percent, returning both indexes to growth territory following consecutive periods of contraction of six and four months, respectively. Comments from the panel this month are mixed, with some indicating a strengthening of demand and others indicating a continuing softness in demand. Additionally, many respondents express uncertainty about government regulations, taxes and global economics in general as we approach 2013.”
PERFORMANCE BY INDUSTRY – Of the 18 manufacturing industries, seven are reporting growth in December in the following order: Furniture & Related Products; Paper Products; Petroleum & Coal Products; Wood Products; Primary Metals; Computer & Electronic Products; and Food, Beverage & Tobacco Products. The nine industries reporting contraction in December — listed in order — are: Nonmetallic Mineral Products; Chemical Products; Miscellaneous Manufacturing; Plastics & Rubber Products; Fabricated Metal Products; Transportation Equipment; Machinery; Electrical Equipment, Appliances & Components; and Apparel, Leather & Allied Products.
It is interesting to note that ISM Manufacturing represents less than 10% of USA employment, and approximately 20% of the business economy. Historically, it could be argued that the production portion of ISM Manufacturing leads the Fed’s Industrial Production index – however the correlation is not strong when looking at trends.
New orders have direct economic consequences. Expanding new orders is a relatively reliable sign a recession is NOT imminent. However, New Orders contraction have given false recession warnings twice since 2000. This subindex is in a long term downtrend – and remains close to contraction.
However, holding this and other survey’s Econintersect follows accountable for their predictions, the following graph compares the hard data from Industrial Products manufacturing subindex (dark blue bar) and US Census manufacturing shipments (lighter blue bar) to the ISM Manufacturing Survey (pink bar).
Comparing Surveys to Hard Data
Caveats on the use of ISM Manufacturing Index:
This is a survey, a quantification of opinion – not facts and data. However, as pointed out above, certain elements of this survey have good to excellent correlation to the economy. Surveys lead hard data by weeks to months, and can provide early insight into changing conditions.
Many use ISM manufacturing for guidance in estimating manufacturing employment growth. Econintersect has run correlation coefficients for the ISM manufacturing employment and the BLS manufacturing employment data series above going back to 1988, using quarterly data. The coincident correlations are actually negative, but poor (r = -0.2 to -0.4 for various time periods examined). See here for definitions.
Before 2000 the ISM employment data had a weak positive correlation to the BLS data 4 to 7 quarters later (r values above 0.6). Since 2000 the correlations for ISM manufacturing employment as a leading indicator for the BLS manufacturing employment have been between 0 and 0.3 for r (correlation coefficient). These values define correlations as none to poor.
In other words, ISM employment index is not useful in understanding manufacturing jobs growth. The graph below shows BLS manufacturing employment month-over-month gains against the ISM Manufacturing employment index.

The ISM employment index appears useful in predicting turning points which can lead the BLS data up to one year.
