Today's charts are intended to give investors a visual perspective on historical and estimated earnings performance for the S&P 500 Index (“LargeCap Index”), the S&P MidCap 400 Index (“MidCap Index”), and the S&P SmallCap 600 Index (“SmallCap Index”). The charts track each Index’s quarterly reported earnings per share (EPS) beginning in Q4’23 through Q3’25. They also include Bloomberg’s estimated EPS for Q4’25.

As the chart reveals, headline EPS increased in Q3’25 (both quarter-over-quarter and year-over-year), with Q4’25 estimates signaling continued strength.

Year-over-year EPS increased by 11.27% (LargeCap Index), 4.86% (MidCap Index), and 7.57% (SmallCap Index) in Q3’25. Year-over-year earnings growth rate estimates for Q4’25 are currently as follows: 10.34% (LargeCap Index), 3.88% (MidCap Index), and 4.96% (SmallCap Index).

Estimated 2025 calendar year EPS for each Index were as follows (not in the charts): S&P 500 Index ($271.37); S&P MidCap 400 Index ($181.32); S&P SmallCap 600 Index ($86.22). 

Year-over-year earnings growth rates implied by these estimates are as follows: S&P 500 Index (+13.89%); S&P MidCap 400 Index (+1.69%); S&P SmallCap 600 Index (+7.16%). Despite their estimated growth, annual EPS for the MidCap and SmallCap Indices remain below their all-time highs of $194.25 and $97.53, respectively, which were both set in 2022. The overall trend is positive, however, and may imply that analysts expect a favorable climate for small and mid-sized companies in the near-term. 

Takeaway: We wrote extensively about the S&P 500 Index’s earnings earlier this week (click here). Today we provide an extended view into the earnings climate of the mid and small-cap segments of the market as well. We believe that corporate earnings drive the direction of stock prices over time, especially when the major indices are trading at or near record highs. As the data shows, EPS are expected to trend higher across each of these Indices in Q4’25, with full year estimates reaching record highs for each Index tracked in 2026. As always, these are estimates and are subject to change (and have changed since our last post). We will continue to report back as developments warrant.
