Q2-23 reporting is about halfway complete for firms in the S&P 500. Bottom-up operating EPS estimates for Q2 are once again sliding lower as we wade farther into earnings season. This attrition is not uncommon but it is certainly a break from Q1 announcements, where EPS estimates rose 5% over the course of reporting. Q1’s action was a bullish talking point for many who touted the end of higher-than-normal erosion in forward EPS estimates over the past year. Since peaking in April 2022 at $61.56, Q2’s EPS estimate has shrunk nearly 17% (Chart 1).
