The Purchasing Managers' Index (PMI) is a widely used economic indicator that measures the health of the manufacturing sector. It is calculated by surveying a panel of purchasing managers and asking them to rate their outlook on a number of factors, such as production, new orders, and employment. The results are then compiled into an index that ranges from 0 to 100, with a reading above 50 indicating expansion and a reading below 50 indicating contraction.
The PMI is a valuable tool for economists and investors because it provides an early indication of the direction of the economy. It is also used by businesses to make decisions about production, inventory, and hiring. The PMI is calculated by a number of private companies, including the Institute for Supply Management (ISM) in the United States and Markit in the United Kingdom. The ISM PMI is the most widely followed, and it is often referred to simply as the PMI.
The PMI is calculated using a formula that weights the responses of purchasing managers based on the size of their companies. The calculation is also adjusted for seasonal variations, which can distort the data.

Surveys purchasing managers.
The PMI is calculated by surveying a panel of purchasing managers from a variety of manufacturing industries. These managers are asked to rate their outlook on a number of factors, including production, new orders, and employment. They are also asked about their expectations for the future.
-
Panel selection:
The panel of purchasing managers is carefully selected to ensure that it is representative of the manufacturing sector as a whole. The managers are selected from a variety of industries and company sizes.
-
Survey questions:
The purchasing managers are asked a series of questions about their current and future outlook. The questions are designed to capture the overall health of the manufacturing sector.
-
Responses:
The purchasing managers respond to the survey questions on a scale of 0 to 100. A rating of 50 indicates that there is no change from the previous month. A rating above 50 indicates expansion, while a rating below 50 indicates contraction.
-
Compilation:
The responses from the purchasing managers are compiled into an index that ranges from 0 to 100. The index is calculated by weighting the responses of the purchasing managers based on the size of their companies. The index is also adjusted for seasonal variations.
The PMI is a valuable tool for economists and investors because it provides an early indication of the direction of the economy. It is also used by businesses to make decisions about production, inventory, and hiring.
Rates factors like production, orders.
The PMI survey asks purchasing managers to rate their outlook on a number of factors, including production, new orders, and employment. These factors are important because they are key indicators of the health of the manufacturing sector.
-
Production:
Purchasing managers are asked to rate their outlook on production levels in the coming month. A positive rating indicates that they expect production to increase, while a negative rating indicates that they expect production to decrease.
-
New orders:
Purchasing managers are also asked to rate their outlook on new orders. A positive rating indicates that they expect to receive more orders in the coming month, while a negative rating indicates that they expect to receive fewer orders.

Index from 0 to 100.
The PMI index is calculated by weighting the responses of the purchasing managers based on the size of their companies. The index is also adjusted for seasonal variations.
The PMI index ranges from 0 to 100. A reading above 50 indicates that the manufacturing sector is expanding, while a reading below 50 indicates that the manufacturing sector is contracting.
The PMI index is a diffusion index, which means that it is based on the percentage of purchasing managers who report an increase in activity, compared to the percentage who report a decrease in activity. A reading of 50 indicates that the number of purchasing managers who report an increase in activity is equal to the number who report a decrease in activity.
The PMI index is a leading indicator of economic activity. This means that it can provide an early indication of the direction of the economy. A rising PMI index typically indicates that the economy is growing, while a falling PMI index typically indicates that the economy is contracting.
The PMI index is a valuable tool for economists and investors. It is also used by businesses to make decisions about production, inventory, and hiring.
Above 50 indicates expansion.
A PMI reading above 50 indicates that the manufacturing sector is expanding. This means that more purchasing managers are reporting an increase in activity than are reporting a decrease in activity.
-
Increased production:
When the PMI is above 50, it typically indicates that production levels are increasing. This is a positive sign for the economy, as it means that businesses are producing more goods and services.
-
Rising new orders:

A PMI reading above 50 also typically indicates that supplier deliveries are faster. This is a positive sign for the economy, as it means that businesses are receiving their supplies more quickly.
Overall, a PMI reading above 50 is a positive sign for the economy. It indicates that the manufacturing sector is expanding and that the economy is growing.
Below 50 indicates contraction.
A PMI reading below 50 indicates that the manufacturing sector is contracting. This means that more purchasing managers are reporting a decrease in activity than are reporting an increase in activity.
A PMI reading below 50 is a negative sign for the economy. It typically indicates that production levels are decreasing, new orders are falling, employment levels are declining, and supplier deliveries are slower.

Businesses use PMI for decisions.
Businesses use the PMI to make decisions about production, inventory, and hiring.
Production: A rising PMI index typically indicates that businesses should increase production. This is because a rising PMI index suggests that demand for goods and services is increasing. Conversely, a falling PMI index typically indicates that businesses should reduce production. This is because a falling PMI index suggests that demand for goods and services is decreasing.
Inventory: Businesses also use the PMI to make decisions about inventory levels. A rising PMI index typically indicates that businesses should increase their inventory levels. This is because a rising PMI index suggests that demand for goods and services is increasing. Conversely, a falling PMI index typically indicates that businesses should reduce their inventory levels. This is because a falling PMI index suggests that demand for goods and services is decreasing.
Hiring: Businesses also use the PMI to make decisions about hiring. A rising PMI index typically indicates that businesses should hire more workers. This is because a rising PMI index suggests that the economy is growing and that businesses need more workers to meet demand.

Calculated by private companies.
The PMI is calculated by a number of private companies, including the Institute for Supply Management (ISM) in the United States and Markit in the United Kingdom.
These companies collect data from a panel of purchasing managers and use this data to calculate the PMI index. The ISM PMI is the most widely followed, and it is often referred to simply as the PMI.
The PMI is a valuable tool for economists, investors, and businesses. However, it is important to note that the PMI is not an official government statistic. This means that it is not subject to the same level of scrutiny as government data.
As a result, it is important to be aware of the potential limitations of the PMI. For example, the PMI is based on a survey of purchasing managers. This means that it is possible for the PMI to be biased if the survey respondents are not representative of the manufacturing sector as a whole.
Overall, the PMI is a valuable tool for economic analysis. However, it is important to be aware of its limitations and to use it in conjunction with other economic data.
