Highlights

The Chicago PMI fell back by 8.9 points to 46.9 in December from 55.8 in November to reverse almost all of its remarkable November rise from 44.0 in October. The December result was much weaker than the consensus 50.0 expectation and below the range of forecasts at 49.4 to 53.0, just as the November result was far above forecasts.

The Chicago report, which includes both manufacturing and non-manufacturing businesses, is highly volatile, presumably reflecting a small sample size. The November surge may also have reflected the impact of the end of the UAW autoworkers strike.

Market Consensus Before Announcement

The Chicago PMI is expected to fall back in December to 50.0 versus November's much higher-than-expected 55.8, a result that ended more than a full year of contraction.

Definition

The Institute For Supply Management - Chicago compiles a survey and a composite diffusion index of business conditions in the Chicago area. Since October 2011, the survey has been conducted by Market News International. Manufacturing and non-manufacturing firms both are surveyed. Hence, it is not directly comparable to pure manufacturing surveys. Readings above 50 indicate an expanding business sector.

Description

Although the report is commonly referred to as the Chicago PMI, the official name of this report is ISM - Chicago. ISM stands for Institute For Supply Management while PMI is shorthand for purchasing managers' index.

Investors should track economic data like the Chicago PMI to understand the economic backdrop for the various markets. The stock market likes to see healthy economic growth because that translates to higher corporate profits. The bond market prefers a moderate growth environment that will not generate inflationary pressures. The Chicago PMI gives a detailed look at the Chicago region's manufacturing and non-manufacturing sectors. Many market players, focused on manufacturing, don't realize that non-manufacturing activity is covered in this index. On its own, it can be viewed as a regional indicator of general business activity. Some of the Chicago PMI's sub-indexes also provide insight on commodity prices and other clues on inflation. One should be aware that this report is released to private subscribers several minutes prior to release to the media. This may account for occasional market activity just prior to public release.

This survey is somewhat local in nature, reflecting overall economic activity in the Chicago area. But many see the Chicago PMI as being representative of the overall economy.

Markets focus on the overall index - the Business Barometer which many refer to as the Chicago PMI. The breakeven point for the index is 50. Readings above 50 indicate positive growth while numbers below 50 indicate contraction. The farther the reading is from 50, the more rapid the pace of growth or decline.
