The PRIX index uses a diffusion index methodology based on that of PMIs. However, rather than drawing on purchasing managers, it uses country analysts based in the world's 20 largest oil exporting countries to forecast political events that may affect global oil exports. Diffusion indexes are typically used when surveys such as Purchasing Managers’ Index™ (PMI™) surveys ask respondents to report whether a variable, such as their output or employment numbers, has risen, remained unchanged or fallen during the survey period in question. A diffusion index measures how many stocks are advancing within an index, typically on a daily time frame. In other words, it measures how many stocks advanced from the close of the prior session. The tick index is a shorter-term breadth indicator, as it measures how many stocks had an uptick versus a downtick. A PMI index over 50 represents growth or expansion within the manufacturing sector of the economy compared with the prior month. A reading under 50 represents contraction, and a reading at 50 indicates an equal balance between manufacturers reporting advances and declines in their business. The Purchasing Managers' Index (PMI) is an indicator of economic health for manufacturing and service sectors.
2 Feb 2006 Since the PMI is a composite of diffusion indexes, the relevance of a diffusion index must be understood. A diffusion index is cre- ated by 1 May 2015 plus one-half of those responding the same (considered positive). The composite PMI is a weighted average of the following diffusion indices: The PRIX index uses a diffusion index methodology based on that of PMIs.

The Purchasing Managers' Index (PMI) is an indicator of economic health for manufacturing and service sectors. PMI indices are calculated as diffusion indices. For each variable, the index is the sum of the percentage of ‘higher’ responses and half the percentage of ‘no change’ responses. The indices vary between 0 and 100, with a reading above 50 indicating an overall increase compared to the previous month, and below 50 an overall decrease.
21 Oct 2019 Constructing the diffusion indices. For the purposes of this analysis, diffusion indices comparable with the Purchasing Managers' Index (PMI) The Diffusion Index shows the general tendency of respondents about a certain Business Confidence Index (BCI) and Purchasing Managers Index (PMI) are For China and USA the indicators used correspond to the PMI, which are normally expressed as diffusion indices. The OECD converts the indices into balances PMI, Production PMI, Employment PMI, Supplier Deliveries PMI, Own Inventories PMI. The sub‐indexes are computed using a diffusion index methodology. 22 Nov 2019 U.S. Composite PMI Output Index posted 51.9 in Diffusion indexes have the properties of leading indicators and are convenient summary Created with Highstock 1.3.7 Zoom Diffusion index, seasonally adjusted General Business Conditions -40 -20 0 20 40 60 80 2010 2020 1m 3m 6m YTD 1y All. if the manufacturing PMI and its key sub-indices can shed light on the performance in the form of diffusion indices.

The Purchasing Managers' Index (PMI) is an index of the prevailing direction of economic trends in the manufacturing and service sectors. It consists of a diffusion index that summarizes whether market conditions, as viewed by purchasing managers, are expanding, staying the same, or contracting. The ISM Manufacturing PMI in the US fell to 51.2 in July 2019 from 51.7 in the previous month, missing market expectations of 53.4. The latest reading pointed to the weakest pace of expansion in the manufacturing sector since August 2016. The ISM Manufacturing PMI in the US fell to 51.7 in June The PMI is a composite index based on the seasonally adjusted diffusion indices for five of the indicators with varying weights: New Orders --30% Production --25% Employment --20% Supplier Deliveries --15% and Inventories -- 10%. The PMI ® is a composite index based on the diffusion indexes of five of the indexes with equal weights: New Orders (seasonally adjusted), Production (seasonally adjusted), Employment (seasonally adjusted), Supplier Deliveries (seasonally adjusted), and Inventories.
