ISM Non-Manufacturing: May Beats Expectations

Today the Institute for Supply Management published its latest Non-Manufacturing Report. The headline NMI Composite Index is at 56.3 percent, up from last month's 55.2 percent. Today's number came in above the Investing.com forecast of 55.5.

Here is the report summary:

"The NMI® registered 56.3 percent in May, 1.1 percentage points higher than April are reading of 55.2 percent. This represents continued growth at a faster rate in the Non-Manufacturing sector and is the highest reading for the index since August 2013, when the index registered 57.9 percent. The Non-Manufacturing Business Activity Index increased to 62.1 percent, which is 1.2 percentage points higher than the April reading of 60.9 percent, reflecting growth for the 58th consecutive month at a faster rate. The New Orders Index registered 60.5 percent, 2.3 percentage points higher than the reading of 58.2 percent registered in April. The Employment Index increased 1.1 percentage points to 52.4 percent from the April reading of 51.3 percent and indicates growth for the third consecutive month and at a faster rate. The Prices Index increased 0.6 percentage point from the April reading of 60.8 percent to 61.4 percent, indicating prices increased at a faster rate in May when compared to April. According to the NMI®, 17 non-manufacturing industries reported growth in May. The majority of respondents' comments indicate that that there is steady incremental growth and project a positive outlook on business conditions."

Like its much older kin, the ISM Manufacturing Series, I have been reluctant to focus on this collection of diffusion indexes. For one thing, there is relatively little history for ISM's Non-Manufacturing data, especially for the headline Composite Index, which dates from 2008. The chart below shows Non-Manufacturing Composite. We have only a single recession to gauge is behavior as a business cycle indicator.

In my view, the more interesting and useful subcomponent is the Non-Manufacturing Business Activity Index. The latest data point at 62.1 percent is a 1.2 increase from the previous month.

For a diffusion index, this can be an extremely volatile indicator. Thus I've added a six-month moving average to assist us in visualizing the trend, which has been relatively range bound for the past two years, and we're currently at the bottom of the range.

Theoretically, I believe, this indicator will become more useful as the timeframe of its coverage expands. Manufacturing may be a more sensitive barometer than Non-Manufacturing activity, but we are increasingly a services-oriented economy, which explains my intention to keep this series on the radar.
