Robust 2026-2027 Earnings Growth is a Live Probability

The Wall Street consensus for S&P 500 earnings growth sits at 21.8% for calendar 2026 and another 14.8% in 2027. Those look like big, tough-to-achieve numbers, but they are totally doable if we check the historic record. Going back to the early 1980s, the S&P’s annual earnings growth rate peaked 53, 76, 59, 44, 40, and 41 months after the Fed embarked on its rate cutting cycles. The year-over-year earnings growth rate at those peaks was 41%, 20%, 16%, 23%, 41% and 51%, sequentially.

In the current cycle, the Fed started cutting rates 19 months ago, in September 2024. If past is prologue, earnings growth could hit its most stretched point as far out as 2028, 2029, maybe even 2030.

We mapped out some S&P 500 scenarios using the earnings consensus to try to get a gauge for where the S&P 500 may go in 2028, based on what will then be trailing earnings for 2027. As we parse through the numbers, we take Yogi Berra to heart: “It’s tough to make predictions, especially about the future.”

Nevertheless, start with a wildly bullish outcome: the S&P in 2028 decides to trade for a P/E multiple on trailing earnings akin to what we saw in the 2021 mania. In that scenario, the market would run to 10,369 from 7,152 today.

For the bears, how about the 2022 P/E low? On 2027 earnings, the S&P would close 2028 at 6,137. The issue with that figure: if the S&P spends the better part of the next three years declining by roughly a thousand points, it would seem logical that the reason is a problem in the “E” part of P/E, whereas our thought experiment assumes the consensus nails it on earnings growth.

Here are some middling scenarios. Using the median trailing price/earnings ratio of the last two decades, and assuming the Street gets the earnings picture right in 2026 and 2027, the S&P would close 2028 at 6,624. But if we change the multiple to the median of the last 10 years, we get 7,533. How about the median since March 2020, to capture the COVID and post-COVID eras? On those valuations, the S&P would hit 8,702. Outside of the 2021 scenario, none of these figures are the stuff of raging bull markets, and some would best be described as a grinding, annoying, but not devastating quasi-bear.

Perhaps the best reason to stay the course in stocks is to figure out if inflation, labor dynamics and other primary concerns will come bite us.
