One of the weakest points of the report, according to Markit's Chief Business Economist Chris Williamson, was the growth in orders for manufacturing firms.
"However, a slowdown in overall order book growth is a warning light that domestic demand has waned in August, and the pull-back in hiring suggests manufacturers have become increasingly cautious about the outlook," wrote Williamson in the release.
The reading on the health of America's industrial sector fell from the prior month's 52.9
July's reading was the strongest since November 2015, which mitigates the disappointment and the reading was still above 50, signalling expansion. The August reading is less worrying given the strong number the month prior, said Williamson, but the new report was nonetheless "disappointment."
Export growth was the strongest in 23 months, but was held back slightly due to concerns over the US presidential election according to the release.
"While some companies commented that a number of clients had adopted a wait-and-a-see approach until the outcome of the presidential election, others mentioned that total new work had been boosted by new foreign client wins over the latest survey period," said the release.
Employment was weaker than recent readings, according to the release from Markit, registering the weakest month for payroll growth in four months.
