At first, just look at the chart superficially. These results are based on surveys of businesses of a wide variety of sizes, spread across all sectors of the economy (except agriculture and government), in all regions of the US. They're asked about their own businesses, in terms of sales, employment, and capital investment over the next 12 months. And the chart also shows how uncertain the participants are about their own expectations.
So this is about expectations for their own businesses, and about the uncertainty of their own expectations. For now, just look at the chart without analyzing it: It shows better than just about anything else what mess businesses face going forward: Their world has gone haywire.
