ISM Manufacturing Index: Continued Expansion

Courtesy of Doug Short.

Today the Institute for Supply Management published its monthly Manufacturing Report for October. The latest headline PMI was 59.0, a rise from Septembers 56.6 percent and above the Investing.com forecast of 56.2.

Here is the key analysis from the report:

“The October PMI® registered 59 percent, an increase of 2.4 percentage points from September’s reading of 56.6 percent, indicating continued expansion in manufacturing. The New Orders Index registered 65.8 percent, an increase of 5.8 percentage points from the 60 percent reading in September, indicating growth in new orders for the 17th consecutive month. The Production Index registered 64.8 percent, 0.2 percentage point above the September reading of 64.6 percent. The Employment Index grew for the 16th consecutive month, registering 55.5 percent, an increase of 0.9 percentage point above the September reading of 54.6 percent. Inventories of raw materials registered 52.5 percent, an increase of 1 percentage point from the September reading of 51.5 percent, indicating growth in inventories for the third consecutive month. Comments from the panel generally cite positive business conditions, with growth in demand and production volumes.”

Here is the table of PMI components.

I’m reluctant to put too much focus on this index for various reasons, but they are essentially captured in Briefing.com’s Big Picture comment on this economic indicator.

This [the ISM Manufacturing Index] is a highly overrated index. It is merely a survey of purchasing managers. It is a diffusion index, which means that it reflects the number of people saying conditions are better compared to the number saying conditions are worse. It does not weight for size of the firm, or for the degree of better/worse. It can therefore underestimate conditions if there is a great deal of strength in a few firms. The data have thus not been either a good forecasting tool or a good read on current conditions during this business cycle. It must be recognized that the index is not hard data of any kind, but simply a survey that provides broad indications of trends.

The chart below shows the Manufacturing Composite series, which stretches back to 1948. I’ve highlighted the eleven recessions during this time frame and highlighted the index value the month before the recession starts.

For a diffusion index, the latest reading of 59.0 indicates expansion. What sort of correlation does that have with the months before the start of recessions? Here are the eleven data points for the months before recessions arranged in numeric order. The latest data pointed (highlighted in red) is higher than the level prior to ten of the eleven.

42.1, 44.8, 45.7, 47.2, 47.8, 48.5, 49.2, 50.5, 50.7, 53.2, 59.0, 66.2

How revealing is today’s 2.4 point change from last month? There are 802 monthly data points in this series. The absolute average month-to-month point change is 2.0 points. So the 2.4 point month-over-month change in today’s headline PMI number is slightly above the average MoM change.

Here is a closer look at the series beginning at the turn of the century.

To reiterate the Briefing.com assessment: “The data have thus not been either a good forecasting tool or a good read on current conditions during this business cycle.” The ISM reports nevertheless offer an interesting sidebar to the ongoing economic debate.

Note : I use the FRED USRECP series (Peak through the Period preceding the Trough) to highlight the recessions in the charts above. For example, the NBER dates the last cycle peak as December 2007, the trough as June 2009 and the duration as 18 months. The USRECP series thus flags December 2007 as the start of the recession and May 2009 as the last month of the recession, giving us the 18-month duration. The dot for the last recession in the charts above are thus for November 2007. The “Peak through the Period preceding the Trough” series is the one FRED uses in its monthly charts, as illustrated here.
