Third Quarter Equity Outlook

The Great Lengthening

Over the past roughly 40 years, a marked change has crept into the U.S. economy: periods of economic expansion have substantially lengthened. In fact, going all the way back to 1854, the average economic expansion lasted just over 40 months, or roughly three and a half years. However, since 1982, the average economic expansion has lasted over 100 months, or more than eight and a half years. In other words, economic expansions over the past roughly 40 years have more than doubled in length!

It is also worth noting that three of the four longest economic expansions in U.S. history since 1854 all occurred after 1982, again reflecting the fact that economic expansions have significantly lengthened over the past roughly 40 years. And the most recent economic expansion from 2009-2020 was the longest on record, only to be interrupted by the exogenous Covid-19 pandemic.
