This morning the Institute for Supply Management published its monthly Manufacturing Report for September. The latest headline Purchasing Managers Index (PMI) was 55.4, a decrease of 0.6 from 56.0 the previous month. Today's headline number was below the Investing.com forecast of 56.4 percent.

Here is the key analysis from the report:

“The Inventories Index registered 47.1 percent, 2.7 percentage points higher than the August reading of 44.4 percent. The Prices Index registered 62.8 percent, up 3.3 percentage points compared to the August reading of 59.5 percent. The New Export Orders Index registered 54.3 percent, an increase of 1 percentage point compared to the August reading of 53.3 percent. The Imports Index registered 54 percent, a 1.6-percentage point decrease from the August reading of 55.6 percent.

“After the coronavirus (COVID-19) pandemic brought manufacturing activity to historic lows, the sector continued its recovery in September. Survey Committee members reported that their companies and suppliers continue to operate in reconfigured factories and are becoming more proficient at maintaining output. Panel sentiment was optimistic (2.3 positive comments for every cautious comment), an improvement compared to August. Demand expanded, with the (1) New Orders Index growing at strong levels, supported by the New Export Orders Index expanding moderately, (2) Customers’ Inventories Index at its lowest figure since June 2010, a level considered a positive for future production, and the (3) Backlog of Orders Index expanding at a faster rate compared to the prior two months. Consumption (measured by the Production and Employment indexes) contributed positively (a combined 0.9-percentage point increase) to the PMI® calculation, with five of the top six industries continuing to expand output strongly. Employment neared expansion territory for the first time since July 2019. Inputs — expressed as supplier deliveries, inventories and imports — continued to indicate input-driven constraints to further production expansion, but at slower rates compared to August. Inventory levels contracted again due to strong production output and supplier delivery difficulties. Overall, inputs improved compared to August and contributed positively to the PMI® calculation. (The Supplier Deliveries and Inventories indexes directly factor into the PMI®; the Imports Index does not.) Prices continued to expand at higher rates, reflecting a continued shift to seller pricing power — a positive for new-order growth.

“Among the six biggest manufacturing industries, Food, Beverage & Tobacco Products remains the best-performing sector, with Fabricated Metal Products and Chemical Products growing strongly. Computer & Electronic Products and Transportation Equipment expanded moderately. Petroleum & Coal Products remained a headwind to PMI® performance.

“Manufacturing performed well in the month with demand, consumption and inputs registering growth indicative of a normal expansion cycle. While certain industry sectors are experiencing difficulties that will continue in the near term, the manufacturing community as a whole has learned to conduct business effectively and deal with the variables imposed by the COVID-19 pandemic,” says Fiore.
