ISM Manufacturing PMI reflects business conditions in the US manufacturing sector in the specified month. The indicator is based on a survey of representatives from more than 400 companies. Unlike Markit, ISM considers not only private companies but is based on the common NAICS (North American Industrial Classification System) list. The questionnaire considers employment, production level, inventories, new orders and supplier deliveries.
Readings above 50 can have a positive effect on US dollar quotes.
