ISM Manufacturing in United States
It is a measurement where US executives in the manufacturing unit are surveyed to acquire their expectations in future inventories, production, deliveries, new orders and employment. Because manufacturing fluctuations influence the overall economic trend, changes in this figure may have significant impact over the GDP. Furthermore, the ISM is one of the most influential measurement in indicating economic turnarounds. For example if the ISM increases over times of recession, this indicates a jump in manufacturing demand and thus a upward jump in the economy.
