Definition of 'ISM Non-Manufacturing Index'
An index based on surveys of more than 400 non-manufacturing firms' purchasing and supply executives, within 60 sectors across the nation, by the Institute of Supply Management (ISM). The ISM Non-Manufacturing Index tracks economic data, like the ISM Non-Manufacturing Business Activity Index. A composite diffusion index is created based on the data from these surveys, that monitors economic conditions of the nation.
Investopedia explains 'ISM Non-Manufacturing Index'
By monitoring the ISM Non-Manufacturing Index, investors are able to better understand national economic conditions. When this index is increasing, investors can assume that the stock markets should increase because of higher corporate profits. The opposite can be thought of the bond markets, which may decrease as the ISM Non-Manufacturing Index increases because of sensitivity to potential inflation.
The ISM Non-Manufacturing Index gets more attention than its manufacturing counterpart, partially due to its seasonally adjusted figures for several of its components.
