Registering 57.2 for April, the Gardner Business Index (GBI): Precision Machining fell slightly from the prior month’s reading. For reference, the latest reading is higher than the peak reached during the last cyclical high recorded in 2014. Compared with the same month one year ago, the index increased by almost 8 percent. Gardner Intelligence’s review of the underlying data indicates that supplier deliveries and employment lifted the business index higher. The components, which lowered the index’s average-based calculation included production, new orders, backlog and exports. Exports contracted for a second consecutive month.

The latest month’s components readings showed that supplier deliveries led the index for a second consecutive month. The last time such an event occurred was in mid-2016. Gardner Intelligence’s interpretation of the components data is that strong new orders growth during the fourth quarter of 2017 was then followed by a sharp increase in production during the first quarter of 2018. As manufacturers increased production to meet heightened demand they stressed their supply chains, causing Gardner’s supplier delivery readings to peak in the most recent months.
