Today’s post provides an update to 2026 and 2027 earnings and revenue growth rate estimates for the S&P 500 Index (“Index”) and each of its eleven sectors. The Index closed at 7,409 on 5/15/26, below its all-time high of 7,501 (5/14/26), and up a staggering 50.7% (total return) from its most recent low of 4,983 (4/8/25). For comparison, from 1928-2025 (98 years) the Index posted an average annual total return of 9.8%.

Calendar year 2026 earnings growth rate estimates increased since our last post on this topic.

The Index’s year-over-year (y-o-y) earnings growth rate estimates were observed at 22.6% and 14.7% in 2026 and 2027, respectively, on 5/15/26. Estimates for calendar year 2026 have increased since our last post when they came in at 13.7%. Click here to view that post. Not a single sector is estimated to see earnings decline y-o-y in 2026.

Revenue growth rate estimates remain favorable as well. In fact, observations for 2026 also increased since our last post on this topic.

The Index’s 2026 estimated y-o-y revenue growth rate totaled 10.4% on 5/15/26, up from 7.3% on 2/23/26 (the date of our last post). Each of the Index’s eleven sectors reflect positive y-o-y revenue growth rate estimates in 2026, with ten of them estimated to surpass 5.0% (up from nine in February). Information Technology commands the highest estimated revenue growth rates at 27.8% and 18.5% in 2026 and 2027, respectively.

Takeaway: Earnings and revenue growth rate estimates reflect continued strength, with ten of the Index’s eleven sectors seeing increased 2026 earnings growth rate estimates since 2/23/26 (data from our last post on this topic). The Index itself saw estimated 2026 earnings growth rates increase from an already favorable 13.7% in February, to an astonishing 22.6% on 5/15/26. Unsurprisingly, increased estimates translated into higher equity prices, with the Index surging to an all-time high of 7,501 on 5/14/26. Revenue growth rates remain persistently positive as well, with 2026 and 2027 registering estimated increases of 10.4% and 7.1%, respectively. We find calendar year 2026 estimates particularly notable as they reflect difficult comparisons for most sectors (2025 earnings were also quite strong). As revealed in the table, Energy, Information Technology and Materials stand out among their peers for 2026 earnings growth rate estimates. That said, the increases in earnings growth rate estimates exhibit wide dispersion. As noted above, 2026 estimates increased for ten of the Index’s eleven sectors over the past few months. Time will ultimately reveal the accuracy of these estimates, but we maintain that higher revenues could be the best catalyst for continued earnings growth.
