Do Earnings Revisions Support Markets Under the Surface?

With 90% of S&P 500 companies having reported second quarter results, corporate America has handily topped expectations, displaying resilience in the face of a challenging policy environment. Although the S&P 500 had a relatively low bar to clear of just 4.9% earnings growth expected for the quarter, America’s largest companies have cruised past estimates. S&P 500 earnings per share (EPS) growth, tracking over 11% year-over-year growth, is more than doubling the level expected at the start of the season on July 1. Alongside the better-than-anticipated results, an earnings season rarity has also caught investors’ attention.

Forward earnings per share (EPS) estimates typically decline over the course of each earnings season as companies adjust guidance and Wall Street fine-tunes its expectations — especially amid times of uncertainty, such as this year, when policy changes cloud the earnings outlook. However, through the end of last week, forward (next 12 months) EPS estimates for the S&P 500 have impressively increased 0.9%. To put this in perspective, over the last 20 quarters (going all the way back to the fourth quarter of 2020) S&P 500 earnings estimates have only risen seven times during the first month of the new quarter. This earnings season marks the seventh occurrence, and five of those instances came in the wake of the COVID-19 pandemic when expectations became far too pessimistic, with the second quarter of 2024 the other rarity.

How does this impact markets? Earnings revisions represent a resetting of expectations, and can be used to help judge an earnings season, but they’ve also been a quiet catalyst underpinning the market. Based on a basket of 100 S&P 500 names curated by our friends at Bloomberg, stocks with the highest earnings revisions over a rolling three-month period outperformed the broader index over both the last year and five years. Year to date, the EPS revision factor trails the S&P 500 by less than 0.3% and is bested only by the size factor, made up of the largest companies by market cap, which is the only basket to outperform the broader index — no surprise here. The EPS revision basket has also (somewhat surprisingly) outperformed the seemingly ever-dominant growth factor. Similarly, performance for the EPS revision factor has been the leading factor across the small cap benchmark Russell 2000 since the start of the year and has led factor returns across the Bloomberg World Index over the same period.

Given that markets are forward looking, it may not come as a surprise that the factor has emerged as a quiet force driving equity performance. The recent and longer-term strength of the factor is a reminder that earnings revisions are one of many important fundamental metrics for market participants to consider, as the factor tends to correlate with pockets of the market that are performing well on a relative basis. Broadly, with earnings revisions ticking higher at the index level this quarter, this gauge of fundamental momentum and market sentiment may continue to act as a tailwind for stocks.
