The Purchasing Managers Index (PMI) is a composite indicator designed to provide an overall view of activity in the manufacturing sector and acts as an leading indicator for the whole economy. The PMI is a composite index based on the diffusion indexes for the following five indicators and their weight: New orders - 0.3, Output - 0.25 , Employment - 0.2, Suppliers delivery times - 0.15 and Stock of items purchased - 0.1 with the Delivery times index inverted so that it moves in a comparable direction. When PMI is below 50.0 this indicates that the manufacturing economy is declining and a value above 50.0 indicates an expansion of the manufacturing economy. The individual survey indexes have been seasonally adjusted using the US Bureau of Census X-11 programme. The seasonally adjusted series are then used to calculate the seasonally adjusted PMI.
A higher than expected reading should be taken as positive/bullish for the INR , while a lower than expected reading should be taken as negative/bearish for the INR.
