Purchasing Managers Index (PMI): Definition, How it works, Formula, Advantages
The Purchasing Managers’ Index, commonly referred to as PMI, is a monthly survey that provides insight into the health of the manufacturing sector. PMI are surveyed about key business metrics like production levels, new orders, employment, supplier delivery times, and inventories. Their responses are used to construct a diffusion index that summarizes economic conditions in the broader industrial economy. As professionals positioned early in the supply chain, purchasing managers feel changes in demand and activity before they are reflected in official output data. This makes the PMI a leading indicator of economic trends.
The Index is calculated from the results of surveys distributed by data firm IHS Markit to over 400 purchasing managers in 19 manufacturing industries across India. Respondents are asked whether conditions have improved, declined, or stayed the same compared to the previous month. These answers are weighted and combined to yield the headline PMI number, with any reading above 50 signaling expansion and below 50 indicating contraction. Higher or lower numbers further signify the strength of improvement or weakness.
Through its focus on both manufacturing orders and production schedules, the PMI sheds light on forthcoming shifts in industrial production, trade, inventories, hiring, and more. Its monthly frequency provides timely guidance to policymakers, businesses, investors, and economists seeking to understand where the economy is headed in advance of quarterly national accounts data. The following sections will explore how the PMI is compiled and interpreted, as well as what its movements typically portend for the broader economy.
What is the purchasing managers’ Index (PMI)?
The purchasing managers’ Index, commonly referred to as PMI, is a survey-based measure of private sector business conditions in the manufacturing sector. The Purchasing Managers’ Index provides insight into business sentiment and economic health by aggregating qualitative data from surveys of purchasing and supply executives at manufacturing firms. Respondents are asked five questions, which are used to compile the headline PMI number, with any reading above 50 indicating expansion and below 50 indicating contraction.
The purchasing managers’ Index utilizes a diffusion index methodology, where the percentage of positive responses to each survey question is given a weight, and then these weighted scores are summed to create the headline figure. This allows the Index to act as a single statistic that conveys the direction and magnitude of change detected across the manufacturing economy from one month to the next. Questions ask firm representatives about new orders, production, employment, supplier deliveries, and inventories.
Essentially, it gauges the pulse of the manufacturing sector from the perspective of materials managers. The genesis of the PMI lies in the need for timely indicators of economic conditions between the months when official government data is released. Back in the 1940s, leaders in the National Association of Purchasing Management, now called the Institute for Supply Management, recognized survey data that could provide crucial early signals of turns in the business cycle. They pioneered the first purchasing managers’ Index as a private metric to fill this information gap and help purchasing executives make better-informed decisions.
The PMI diffusion index itself is calculated as the average of the seasonally adjusted new orders, production, employment, supplier deliveries, and inventory component indices. It represents an early indication of the overall health of the manufacturing sector and trends through the eyes of purchasing managers. A composited index smooths some of the volatility of single component measures, amplifying the signal about the direction of change. Given its monthly frequency and timeliness, it provides forward-looking insight into areas like production, employment, and trade in between government reports.
How purchasing managers’ Index works?
The Purchasing Managers’ Index works by aggregating its insights from monthly surveys of procurement executives across major industries using a diffusion index to distill qualitative input into a single quantitative measure that signals the prevailing direction and velocity of change in business conditions, serving as a valuable leading indicator for decision-makers.
They are coordinated by the esteemed Institute for Supply Management, the non-profit responsible for establishing procurement best practices; each survey wave pollinates over 400 firms at the forefront of 19 industries staple to gross domestic product. Participants spanning sectors as diverse as petroleum and coal products to printing and related support activities are encouraged to candidly assess business conditions from their vantage overseeing procurement chains. Strategically weighting responses by industry output value ensures captured intel mirrors dollars churning through America’s industrial engine room.
Tabulating feedback revolves around a balanced quintet of interrelated queries aimed at illuminating the industrial pulse from multiple complementary angles. The initial question probes new order volumes, tapping a critical early indicator of altering demand dynamics rippling outward. Second examines gyrating stockpiles of materials and finished products, revealing inventories adjusting up or down to satisfy marketplace fluctuations. Third homes in on dynamism inside factory gates through production metrics like operations schedules and unfinished goods.
Logistical supply line performance serves as the next data point, with the expediency of input deliveries from providers signaling constraints or ease within global sourcing networks. Finally, employment levels, both permanent and contingent, round out the report card, conveying hiring and staffing modifications informing future productive potential. Each component contributes equally to the synthesizing diffusion index, canceling out biases to highlight overarching trajectories.
With purchasing directors on the frontlines of industrial tides changing course well in advance of official statistics, the PMI offers a valuable early warning. However, distilling myriad views into a single statistic demands interpretive context. Scores ranging from zero to 100 partition the spectrum of expansion versus contraction. Here, the halfway mark at 50 serves as the stalemate line. Readings above signal prevailing conditions strengthening compared to the last period. Below signals weakening. Moreover, the degree higher or lower from the fulcrum pinpoints intensity.
Naturally, qualitative research leaves room for sentiment fluctuations disconnected from underlying fundamentals. Additionally, the production sector represents just one slice of total output. Yet accuracy earned over decades affirms the PMI as economists’ indispensable compass between major reports, successfully anticipating inventory restocking cycles and output momentum shifts. With a network spanning the industrial supply chain, it illuminates the present to guide strategic planning into the future.
What is the formula for the purchasing manager’s Index?
The purchasing manager’s Index is calculated by multiplying the percentage of survey responses reporting improved conditions by 1, the percentage reporting no change by 0.5, and the percentage reporting worsening conditions by 0. The PMI formula weighs monthly survey responses on business conditions. These weighted figures are summed for each of the five key components, such as new orders, production, employment, supplier delivery times, and inventories.
The formula for PMI = (P1 * 1) + (P2 * 0.5) + (P3 * 0)
Where the three diffusion indexes, P1, P2, and P3, are given below.
P1 represents the “improving percentage,” which measures the percentage of survey respondents reporting an increase in a variable like production or new orders compared to the previous month.
P2 represents the “no change” percentage, which measures the percentage of respondents reporting no change in a variable compared to the previous month.
P3 represents the “deteriorating percentage,” which measures the percentage of respondents reporting a decrease in a variable compared to the previous month.
How to calculate the purchasing manager’s Index?
The purchasing manager’s Index (PMI) for a stock market is calculated by taking the percentage of survey respondents reporting better conditions (P1), adding 0.5 times the percentage reporting no change (P2), and subtracting the percentage reporting worse conditions (P3). The PMI is based on monthly surveys of purchasing managers at companies in the manufacturing sector, who are asked about variables like production levels, new orders, supplier deliveries, inventories, and employment levels.
The responses to these survey questions are used to calculate different diffusion indexes, which measure the percentage of respondents reporting an increase, the percentage reporting no change, and the percentage reporting a decrease. These diffusion indexes are then weighted and combined into a single composite PMI number.
So, for example, with P1=60, P2=20, and P3=10, the PMI calculation would be as given below.
PMI = (60 * 1) + (20 * 0.5) + (10 * 0)
= 60 + 10 + 0
The PMI ranges from 0 to 100, with a reading above 50 indicating overall growth or expansion in the manufacturing sector compared to the previous month. A reading below 50 indicates contraction.
The component weighting means that greater weight is given to the “improving” percentage (P1) and less weight to the “no change” and “deteriorating” percentages. This aims to provide a better balance between expansion and contraction signals in the final PMI.
Let’s look at four examples to illustrate how the formula is applied with different diffusion index values.
P1 = 70% (Improving percentage – 70% of respondents reported an increase)
P2 = 20% (No change percentage)
P3 = 10% (Deteriorating percentage – 10% reported decrease)
PMI = (70 * 1) + (20 * 0.5) + (10 * 0)
= 70 + 10 + 0
This is a strong reading above 50, indicating strong growth and expansion in the manufacturing sector. More weight is given to the high “improving” percentage.
P1 = 40%
P2 = 40%
P3 = 20%
PMI = (40 * 1) + (40 * 0.5) + (20 * 0)
= 40 + 20 + 0
This is a modest reading above 50, indicating continued growth but at a slower pace. The high “no change” percentage dampens the expansion signal somewhat.
P1 = 30%
P2 = 40%
P3 = 30%
PMI = (30 * 1) + (40 * 0.5) + (30 * 0)
= 30 + 20 + 0
A reading of 50 indicates that the manufacturing sector is at a standstill, with equal percentages of respondents reporting expansion and contraction. The high “deteriorating” percentage offsets the “improving” percentage.
P1 = 35%
P2 = 20%
P3 = 45%
PMI = (35 * 1) + (20 * 0.5) + (45 * 0)
= 35 + 10 + 0
This reading below 50 indicates a contraction in the manufacturing sector. More weight is given to the high “deteriorating” percentage than the “improving” percentage.
What is a diffusion index?
A diffusion index is a statistical tool used to aggregate diverse survey responses into a single number that summarizes the general direction and rate of change in the underlying data. Diffusion indexes are popular in economics for tracking sentiment and activity levels based on surveys of purchasing managers, investors, consumers, and other key stakeholders. The concept behind a diffusion index is straightforward.
Survey respondents are asked whether a given metric – like production, employment, or inventories – has increased, decreased, or stayed the same compared to the previous month. Based on the distribution of responses, a diffusion index reading is calculated that ranges from 0 to 100.
The calculation involves assigning a 1.0 weight to the percentage of respondents reporting an increase, a 0.5 weight to the percentage reporting no change, and a 0.0 weight to the percentage reporting a decrease. Suppose 60% is noted as an increase, 30% as no change, and 10% as a decrease; the diffusion index would be 60%*1.0 + 30%*0.5 + 10%*0.0 = 85.
What are the use cases of purchasing managers’ indexes?
The key uses of the PMI include economy, investors, suppliers, and business conditions. Details of the same are given below.
Analysts monitoring the ebbs and flows of macroeconomic conditions rely heavily on the Purchasing Managers’ Index for its early glimpses of shifts underway. As manufacturers comprise a sizable portion of output and employment, their inventories, sales, and staffing serve as leading clues to GDP, production, and job reports months in advance. The PMI thus provides policymakers and central bankers an invaluable compass for adjusting interest rates and fiscal policies accordingly to smooth business cycles. With a network in 19 industries, it illuminates nascent trends across entire sectors that traditional reports obscure.
For market participants allocating vast sums, peeking around the economic corner presents lucrative opportunities. The PMI delivers precisely such foresight through its monthly surveys preceding official data. Rising readings hint at expanding corporate earnings seasons away. Falling scores forecast potential weakness surfacing in analyst calls or economic data points. Either way, the PMI distills reams of qualitative input into investable intelligence, differentiating long-term positions. Through tracking not just the headline figure but component contributions, investors glean a multidimensional perspective on demand, logistics, and employment, supporting more informed capital allocation decisions.
Procurement executives likewise heed the PMI for its portents of procurable demand on their immediate horizon. Suppliers and manufacturers rely on stable orders and pricing power to forecast inventories and payroll accurately. The PMI sheds light on customer volumes, fulfillment times, and purchasing trends, guiding supplier production schedules and quotes. Periods of intensifying expansion signal holding prices while fulfilling bulk orders. Periods of slackening growth compels competitive pricing to sustain relationships. For planners further down industrial chains, the PMI acts as an indispensable monthly compass steering strategic decisions.
- Business Conditions
Perhaps most acutely attuned to PMI fluctuations rests corporate leadership overseeing sprawling operations. Chief procurement officers utilize the Index to inform budgeting cycles in sync with forthcoming sales momentum. Manufacturing executives model facility utilization and shift schedules around new order trends across regions. Logistics controllers replenish or reduce warehouse stocks, heeding inventory changes.
Even human resource directors forecast headcount needs according to hiring components. By distilling sentiment from peers nationwide, the PMI arms corporate strategists with real-time perspective on demand trajectories to proactively position companies for challenges and opportunities ahead.
The Purchasing Managers’ Index fills valuable use cases across the economy, markets, supply chains, and businesses through its early read on shifting conditions in manufacturing. As a leading indicator deeply embedded within industrial operations, the PMI continues empowering more informed decision-making for key stakeholders worldwide.
What does the Purchasing Managers’ Index measure?
The Purchasing Managers’ Index measures month-to-month changes in key business conditions reported by purchasing managers, including production, new orders, employment, inventories, and supplier deliveries. Specifically, the PMI tracks variables like output, new orders, employment, supplier deliveries, and inventory levels. It also includes a forward-looking component based on purchasing managers’ expectations for future output. The survey results are compiled into a composite PMI reading as well as sub-indices for each variable.
A PMI reading above 50 indicates overall growth in the manufacturing sector compared to the prior month, while a reading below 50 signals contraction. The further the reading is from 50, the greater the rate of change, whether positive or negative. As such, the PMI provides real-time insights into the trajectory of the manufacturing industry.
What Sectors Does the PMI Cover?
The PMI covers five major areas such as new orders, inventory levels, production, supplier deliveries, and employment. Each area provides unique insights into economic trends.
The new orders index is based on the question, “Is new business coming in better or worse than last month?” It is one of the most forward-looking components of the PMI. The new orders index reflects the demand side of the economy and provides an early indication of expansions or contractions. High new order growth signals rising demand from consumers and businesses. This typically translates into higher production to meet the incoming orders.
Conversely, a decline in new orders indicates faltering demand, which leads to cutbacks in production. Changes in new orders tend to precede changes in actual production by 1-3 months. Since new orders provide the earliest read on demand trends, this PMI component is useful for assessing the health of the overall economy. Growing new orders point to an expanding economy while declining new orders signal a potential economic downturn. Investors watch the new orders index closely as a leading indicator of economic momentum.
The inventory levels index tracks changes in inventories held by manufacturers and service providers. Rising inventory levels indicate that production exceeds new orders, suggesting slowing demand. Falling inventories signify that new orders exceed production, reflecting stronger demand. The relationship between new orders and inventories provides insights into the balance between supply and demand in the economy. For example, strong new orders coupled with falling inventories point to ramping production to meet rising demand. This combination signals economic expansion. Conversely, weak new orders alongside rising inventories suggest overproduction relative to demand. Companies are able to cut back on output in response, signaling a potential economic contraction. By tracking inventory trends, purchasing managers gauge shifts in aggregate supply and demand.
The production index measures changes in output levels at manufacturers and service providers compared to the previous month. Growth in production indicates companies are ramping up output to meet rising demand. Declining production suggests slowing demand is leading companies to cut back. Shifts in production tend to lag behind new orders by 1-3 months. New orders provide the earliest signal of demand changes, while production responds over subsequent months to align output with sales. Tracking the production index provides insights into how companies are responding to changing demand conditions.
Rising production coupled with strong new orders points to an expanding economy. Falling production alongside weak new orders signals declining economic momentum. Since production changes impact GDP, the Index offers clues into economic growth trends. The supplier deliveries index tracks changes in delivery times of suppliers to manufacturers and service companies. Slower deliveries indicate suppliers are having difficulty keeping up with demand. This reflects tight supply conditions in the economy. Faster deliveries suggest suppliers have excess capacity or falling demand.
Rising new orders overwhelm suppliers, causing delays in fulfilling orders. This indicates strong demand. Supply shortages and disruption constrain suppliers’ ability to deliver orders on time. This points to supply-side constraints. Transportation bottlenecks and logistics challenges cause slow deliveries. This highlights inefficiencies in supply chains. The supplier deliveries index provides insights into inflation trends.
Slower deliveries due to strong demand and tight supply often lead to rising prices as suppliers gain greater pricing power. Conversely, faster deliveries reflect weakening demand and signal disinflationary pressures. The employment index tracks hiring activity at manufacturers and service sector companies. Growing employment indicates rising business confidence and a willingness to boost payrolls to meet increasing demand. Falling employment points to declining optimism and a reluctance to expand payrolls.

What is a composite PMI?
The composite Purchasing Managers’ Index (PMI) is a weighted average of the manufacturing PMI and the services PMI, providing a single comprehensive figure reflecting overall economic conditions. To visualize prevailing commercial conditions across both goods-producing and service-providing spheres, analysts devised the composite purchasing managers’ Index.
Rather than siloed views of manufacturing or tertiary activities alone, this hybrid metric synthesizes both angles into a unified panorama. At the root, discrete PMI surveys continue interrogating procurement specialists independently regarding fluctuations in new orders, payrolls, pricing, and the like specific to their industrial or service realm. However, a composite approach then amalgamates raw data, applying weighted consideration.
Here, weightings stem rationally from each sector’s quantified contribution to gross domestic product as recorded through national accounting aggregates. Respecting shifting economic and architectural foundations over time, attached importance dynamically aligns with documented valuations across industries. For example, an economy transitioning towards a services-led model sees manufacturing importance waning in weighting versus services expanding.
This anchors the composite PMI scientifically to documented structural changes nestled within official output tallies. Once weighted appropriately, procurement sentiment findings from across manufacturing and service spectrums merge through a calculation. Here, responses enter as diffusion indexes enjoying proportional influence tied to financial significance. The ensuing singular number thereby fuses disparate viewpoints into a unified early warning system.
How is the purchasing manager’s index survey conducted?
The purchasing managers’ index survey is conducted through monthly questionnaires distributed to carefully selected panels of procurement executives across industries who report on changes in key business metrics compared to the previous period in order to derive a composite diffusion index tracked over time as a leading economic indicator. Administrators at S&P Global carefully curate representative panels across nations matching official sectoral GDP valuations.
Regularly enlisting approximately 80% response rates ensures accuracy over time. Participation anchors sampling scientifically versus casual volunteering. Questionnaires focus on factual changes to new orders, lead times, stockpiles, backlogs, and payrolls, relinquishing opinions for hard data. Respondents characterize fluctuations since the last period as elevated, steady, or diminished while elucidating seasonal influences. This differentiates underlying macroeconomic tides from expected variations.
Aggregating replies commence by quantifying reporting enhancements separately from those unchanged or deteriorated. Weighting then attaches imports, reflecting sub-sectors financial importance within GDP tallies. Summation derives diffusion indexes tracking divergence from stability signaling intensifying or slackening dynamics. As economic histories evolve, maintained flexibility redistributes weights fittingly.
Composite views also fuse manufacturing and service sector visions through rational GDP allocations. This constructs panoramas attentive to structural transitions between industrial and post-industrial models. Markit Economics applies alternative seasonal adjustments to accommodate immature datasets when histories lack adequate spans. By correlating stated rationales with reported shifts, non-seasonal undercurrents emerge untangled from anticipated fluctuations.
Who conducts a purchasing manager’s index survey?
The top 5 authorities that conduct purchasing managers’ index surveys are IHS Markit (India), ISM (United States), IHS Markit (China), Bank of Japan (Japan), and IHS Markit (United Kingdom). India’s purchasing managers’ index (PMI) survey is conducted by IHS Markit. IHS Markit is a global information provider and a leader in critical information, analytics, and solutions for major industries and markets.

The report has been published since April 2008, providing over a decade’s worth of insights into the Japanese manufacturing economy.
What is the current purchasing managers’ Index in India?
India’s current manufacturing PMI is 56.0 in November 2023, up from 55.5 in October. This marks the 29th straight month of growth in factory activity, with output expanding at an above-trend pace. New orders improved from October’s one-year low and outpaced historical averages. Foreign sales also grew for the 20th month, though at the slowest rate since June. Employment rose for the eighth month despite a slight uptick in outstanding business. Buying activity and input stocks increased due to buoyant demand. Delivery times were largely unchanged as vendor performance deteriorated modestly. Purchase costs rose the least in 40 months. Charges increased modestly as most firms kept fees steady. Confidence dipped to a 7-month low due to rising inflation expectations.
What is the global purchasing managers’ Index?
The global purchasing managers’ Index (PMI) is a composite indicator derived from monthly surveys of private sector companies’ purchasing managers that provides an early indication of economic growth trends across the world’s major economies. The Global Purchasing Managers’ Index provides a comprehensive one-number snapshot of worldwide business conditions by aggregating manufacturing and services PMI surveys from over 40 countries, accounting for approximately 90% of global GDP. It is distinct from singular domestic variants as it amalgamates perceptions across over 40 nations, representing approximately 90 percent of worldwide GDP.
At the foundation, questionnaires distributed monthly by data firm S&P Global probe goods and services enterprises internationally on conditions linked to orders, manufacturing, hiring, and beyond. Responses are pouring in from around 28,000 companies globally seeking clarity on fluctuations since the last period. Individual nation replies are then divided according to improvement, stability, or deterioration responses using established diffusion indexing methodology. Here, enhanced perceptions attract full weighting while others halve or nullify import depending on the message.
Separately, specialized institutes likewise gather manufacturing indices for major countries through respected surveys. Weighing each area appropriately relative to documented contributions to planetary output, sentiments integrating across nations emerge as the composite global PMI. Distinct from fragmented views, its solitary figure offers a panoramic perspective on synchronized dynamical shifts traversing hemispheres.
Readings hovering above 50 signal prevailing international circumstances expanding versus past months, while below denotes slackening. Magnitudes farther from the equipoise also convey vigor underlying alterations. For example, heightened scores are approaching 100 forecasts of robust growth proliferating globally.
What Does a High PMI Reading Indicate?
A high PMI reading indicates improving business conditions compared to the previous month, signaling that the prevailing economic expansion is continuing to build strength. It is encapsulated within the singular quantitative figure yielded by monthly purchasing managers’ index surveys that rests a veritable wellspring of illuminating economic guidance. Through ascribing predefined values relating to improvement, stasis, or deterioration responses, emerging diffusion scores populate a standardized spectrum permitting nuanced interpretation.
How is PMI data collected?
PMI data is collected through surveys of purchasing managers about production, orders, employment, inventories, prices, etc., as well as from economic indicators and reports compiled by statistical agencies and governments containing relevant manufacturing and industrial data. To derive the purchasing managers’ Index each month, researchers canvass a cross-section of procurement specialists populating industrialized sectors. Representatives stem from the esteemed Business Survey Committee of the Institute for Supply Management, encompassing enterprises across manufacturing subfields according to assigned organizational codes.
What are the advantages of PMI?
Early insights are one of the primary advantages of referencing the purchasing managers’ index, which lies in the early glimpses it provides into shifting economic tides. Through regularly surveying procurement managers monthly, fluctuations permeating industrial sectors surface weeks ahead of conventional data points. This presents analysts, policymakers, and enterprises valuable lead time optimizing strategies according to vast changes rippling outward. Being positioned at the forefront of supply chains amplifies detectable signals.
The PMI also benefits from a meticulously designed sampling methodology. By basing participation around the prestigious Business Survey Committee aligned with industrial significance, responses yield accurate microcosms of prevailing circumstances. Additional care ensuring appropriately balanced regional representation bolsters comprehensiveness. Regular 80% response rates safeguard consistency, elevating reliability versus informal collections vulnerable to biases. Rather than singular views, the PMI provides a multidimensional portrait by equating diverse angles synchronously.
New orders, production, payrolls, prices, and beyond surface interrelated dynamics from intricate networks. Breaking results into component contributions further illuminates initiating fluctuations. The policy thus discerns where impetus originates, guiding nuanced support. Corporates optimize resource deployment, understanding influential propagation routes.
The PMI revolutionizes commercial surveillance by algorithmically distilling myriad qualitative surveys into a standardized quantitative index. Weighted categorization according to improving, steady, and deteriorating replies constructs diffusion scores exhibiting momentum directionally. Through condensing complex realities into an intuitive statistic, the process unveils usable intelligence otherwise obscured amid verbal noise. Clear early warnings optimize navigation.
Comparative monthly tallies offer decision-makers enviable foresight into changing tides ahead of gross output tallies. Heights hinting at growth accelerating let strategists proactively position. Declines foreshadowing slowing traction signal potential targets for reforms. Overall, the PMI endows analysts, policymakers, and enterprises with an indispensable compass adjusting aims and tactics favorably shaping prosperity prospects amid fluid environments.
What are the disadvantages of PMI?
The main disadvantage of PMI is that it adds to the cost of obtaining a mortgage. Borrowers have to pay an upfront fee, typically 1-2% of the loan amount, to purchase private mortgage insurance. This increases closing costs and makes it more expensive to get a mortgage, especially for borrowers with less than a 20% down payment who are required to have PMI. PMI also results in higher monthly payments since the premiums are included in the mortgage payment. This increases the borrower’s debt-to-income ratio and makes it harder to qualify for the loan.
Additionally, PMI offers no direct benefit to the borrower – it only protects the lender in case of default. The borrower takes on the added cost with no upside. Finally, it is sometimes difficult to cancel PMI once home equity reaches 20%. Lenders often require an appraisal to confirm home value appreciation and may drag their feet on removing the requirement. This results in borrowers overpaying for unnecessary insurance. In summary, PMI disadvantages borrowers by increasing upfront and monthly costs, providing no direct benefit, and being difficult to remove.
Is PMI a leading indicator?
Yes, the Purchasing Managers’ Index is considered a leading economic indicator. As a monthly survey of procurement managers upstream in supply chains, the PMI detects fluctuations permeating industries before they appear in other lagging reports. Respondents feel changes to orders and activity early on, so movements in the diffusion index typically precede revisions to official output metrics by several months. A track record of the PMI reliably forecasting peaks and troughs in the business cycle confirms its leading quality for identifying forthcoming macroeconomic trends.
