February 2013 ISM Manufacturing Survey Good and Again Above Expectations

Written by

The ISM Manufacturing survey for February 2013 continued rising in expansion territory for the third month in a row. The sub-index which historically correlates to the economy showed strong expansion.

The ISM Manufacturing survey index (PMI) rose from 53.1 to 54.2 (50 separates manufacturing contraction and expansion). This was well above expectations which were between 52.0 and 52.4.

This index has been in a general downtrend since mid 2011 – however, the January data may be suggesting the downward trend is ending.

Relatively deep penetration of this index below 50 has normally resulted in a recession.

The noisy Backlog of Orders jumped from 47.5 to 55.0. 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.

Economic activity in the manufacturing sector expanded in February for the third consecutive month, and the overall economy grew for the 45th consecutive month, say the nation’s supply executives in the latest Manufacturing ISM Report On Business®.

The report was issued today by Bradley J. Holcomb, CPSM, CPSD, chair of the Institute for Supply Management™ Manufacturing Business Survey Committee. “The PMI™ registered 54.2 percent, an increase of 1.1 percentage points from January’s reading of 53.1 percent, indicating expansion in manufacturing for the third consecutive month. This month’s reading reflects the highest PMI™ since June 2011, when the index registered 55.8 percent. The New Orders Index registered 57.8 percent, an increase of 4.5 percent over January’s reading of 53.3 percent, indicating growth in new orders for the second consecutive month. As was the case in January, all five of the PMI™’s component indexes — new orders, production, employment, supplier deliveries and inventories — registered in positive territory in February. In addition, the Backlog of Orders, Exports and Imports Indexes all grew in February relative to January.”

Of the 18 manufacturing industries, 15 are reporting growth in February in the following order: Apparel, Leather & Allied Products; Miscellaneous Manufacturing; Paper Products; Electrical Equipment, Appliances & Components; Plastics & Rubber Products; Fabricated Metal Products; Furniture & Related Products; Petroleum & Coal Products; Wood Products; Printing & Related Support Activities; Transportation Equipment; Nonmetallic Mineral Products; Food, Beverage & Tobacco Products; Machinery; and Primary Metals. The three industries reporting contraction in February are: Textile Mills; Computer & Electronic Products; and Chemical 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.

    That’s a big leap from previous years! Great job! I hope I’ll be able to get up from the recession here. Still having hard times.
