Q3 Earnings Season Preview: What Can Investors Expect?

The outlook for the upcoming Q3 earnings season is notably strong, with aggregate S&P 500 earnings projected to increase 24.0% year-over-year alongside an 11.4% rise in total revenues. This performance marks the eighth consecutive quarter of double-digit earnings growth for the benchmark index. While the Technology sector continues to serve as the dominant driver—bolstered by robust growth forecasts from heavyweights such as NVIDIA and Micron—the overall earnings momentum remains broad-based across the market. Earnings growth is projected to be positive in 14 of the 16 Zacks sectors, with double-digit growth anticipated in five sectors: Aerospace (+159.3%), Energy (+111.9%), Technology (+41.9%), Basic Materials (+31.2%), and Transportation (+15.1%). Estimate revisions remain broadly positive across 8 sectors, extending an upward momentum trend that has persisted for nearly a year. Excluding the Energy sector, index earnings growth adjusts to +20%, while excluding Tech drops the rate to +14.4%. The reporting season is scheduled to accelerate materially in mid-October as major financial institutions deliver results.
