The Philly Fed's Manufacturing Business Outlook Survey is a monthly report for the Third Federal Reserve District, covers eastern Pennsylvania, southern New Jersey, and Delaware. While it focuses exclusively on business in this district, this regional survey gives a generally reliable clue as to the direction of the broader Chicago Fed's National Activity Index.

The latest Manufacturing Index came in at 8.5, down 5.2 from last month's 13.7. The 3-month moving average came in at 6.0, down from 8.9 last month. Since this is a diffusion index, negative readings indicate contraction, positive ones indicate expansion. The Six-Month Outlook came in at 19.1, down from the previous month's 21.8.

Today's 8.5 headline number came in below the 10.4 forecast at Investing.com.

Here is the introduction from the survey released today:

Regional manufacturing activity continued to grow in April, according to results from this month’sManufacturing Business Outlook Survey. Although the survey’s indicators for general activity and shipments fell from their readings last month, the indicators for new orders, employment, and the workweek improved. The survey’s indexes for future activity and employment continued to moderate, but the surveyed firms remained generally optimistic about growth over the next six months. (Full Report)

The first chart below gives us a look at this diffusion index since 2000, which shows us how it has behaved in proximity to the two 21st century recessions. The red dots show the indicator itself, which is quite noisy, and the 3-month moving average, which is more useful as an indicator of coincident economic activity. We can see periods of contraction in 2011, 2012 and 2015, and a shallower contraction in 2013. 2016 saw an improvement but has since lost its gains and has been detracting.

In the next chart, we see the complete series, which dates from May 1960. For proof of the high volatility of the headline indicator, note that the average absolute monthly change across this data series is 7.7.

The next chart is an overlay of the General Activity Index and the Future General Activity Index — the outlook six months ahead.

For comparison, here is the latest ISM Manufacturing survey.

Let's compare all five Regional Manufacturing indicators. Here is a three-month moving average overlay of each since 2001 (for those with data).

Here is the same chart including the average of the five. Readers will notice the range in expansion and contraction between all regions.
