Tuesday, May 1 marked the US economy’s second-longest expansion since 1785, according to new research released by Cushman & Wakefield. If this trend continues through July 1, 2019, the expansion of this economic cycle will officially be the longest on record. Cushman & Wakefield’s report examines two of the most popular and widely-watched economic indicators–the yield curve and the state of the US stock market–to offer insight into the state and future of the current expansion. Long expansions are not the historical norm, according to Revathi Greenwood, head of Americas research with Cushman & Wakefield. Until this week, the expansion from 1961 through 1969 was the second longest in US history.—Lisa Brown
