The ISM manufacturing index or purchasing managers' index is considered a key indicator of the state of the U.S. economy.
It indicates the level of demand for products by measuring the amount of ordering activity at the nation's factories.
The PMI number, which is announced on the first business day of each month, can greatly influence investor and business confidence.
An index of more than 50 indicates an expansion in the manufacturing segment of the economy in comparison with the previous month while a reading of 50 indicates no change and a reading below 50 suggests a contraction of the manufacturing sector.
The ISM will be something to watch during the next couple of month giving us indications on the health of the economy
