Is the Two-Year-Old Bull Market 2 Legit 2 Quit?

In markets, a year can feel like a lifetime. Ditto for two years, which is how old the S&P 500's current bull market now is (as of a couple days ago). While that calls for celebration, it perhaps begs for a deeper analysis into the unique nature of this run, what sets it apart from prior bull markets, and the outlook for its longevity.

Before getting into the meat of the current bull, it's instructive to look into its origins. At risk of stating the obvious, every bull market is born out of the end of a bear market. Below we've detailed 14 of the S&P 500's bears (using the standard -20% definition) in the post-WWII era. Bear markets that occurred in conjunction with a U.S. recession are highlighted in red. That has more often been the case, making the most recent downturn the first non-recession bear market since the late 1980s.

SP500 bear markets and recessions

It's not always the case that recessionary bears have worse drawdowns, but they have historically lasted longer. They also tended to breed longer lifespans for the subsequent bull run. Our friends at The Leuthold Group found that the average life of a bull market following a recession is nearly twice as long (61 months) as one that doesn't follow a recession (33 months).

Perhaps unsurprisingly, that has historically tended to mean stronger gains for post-recessionary bull markets. As shown in the table below, the current bull has logged a return of 62.7% in the first two years of its life. That is right in line with the average first two-year gain following a recession (62.9%) but stronger than the average following no recession (40.5%). Looking at gains after the first three years is where the more important distinction is, though. The average return for the S&P 500 bull's first three years following no recession is 41.9%, not that much stronger than the average in the first two years. Yet, following a recession, the average return for the first three years is much stronger at 66.8%.
