ISM Index

The Institute for Supply Management (ISM), formerly the National Association of Purchasing Management (NAPM), releases the “Report on Business” on the first working day of each month. Part of this report is the “diffusion index,” which tracks the economy’s ups and downs well.

In conducting this survey, the ISM questions purchasing executives from over 250 industrial companies compiling data on production, orders, commodity prices, inventories, vendor performance, and employment. Each of the respondents is asked to rank the categories as “up” or “down.” Various weights are applied to the individual components to form the composite index. A composite index reading of 50 can be thought of as a “swing point.” A reading above 50 implies an increase in economic activity, while a reading below 50 indicates a decline. The ISM report is difficult for economists to forecast because there is little data upon which to base an educated guess. The report has a large “surprise factor” and can cause market swings.

Be cautious heading into the data this week. The MBS market has seen extended periods of quiet trading but could be on the edge of volatility with continued fear and uncertainty in the financial markets.
