Q3 Earnings Season Setup Remains Favorable: What to Know

The Q3 earnings season is underway with a notably positive estimate revisions trend, particularly in the Finance and Tech sectors, which are driving the aggregate S&P 500 outlook. Current expectations project Q3 earnings growth of +5.7% on +6.1% higher revenues for the S&P 500, an upward revision from +4.2% at the quarter's start, though this pace would be the slowest in two years if not surpassed. This week's reports from major financial institutions, including JPMorgan and Bank of America, will be critical in validating these positive revisions and influencing the broader market's Q4 expectations, especially given JPMorgan's strong year-to-date performance and continued positive estimate revisions.

Analysis

The Q3 earnings season commences with a notably positive estimate revisions trend, particularly driven by the Finance and Technology sectors, which collectively account for nearly half of the S&P 500's total earnings. Current expectations for Q3 S&P 500 earnings growth stand at +5.7% year-over-year on +6.1% higher revenues, an upward revision from +4.2% at the quarter's outset. This positive momentum extends into Q4 2025, with favorable revisions noted across eight of the sixteen Zacks sectors.

Despite the aggregate positive trend, a significant divergence exists, with estimates increasing for only six sectors while ten sectors, including Basic Materials and Medical, face downward pressure. While the +5.7% projected growth rate represents an improvement, it would mark the slowest S&P 500 earnings growth in two years if not surpassed, indicating underlying mixed conditions. Early Q3 results from 23 S&P 500 members show promising momentum, with 78.3% beating EPS estimates and 82.6% beating revenue estimates, and earnings up +9.1% on +6.4% revenue.

This week's reports from major financial institutions like JPMorgan Chase (JPM) and Bank of America (BAC) are crucial for validating the positive revisions. JPMorgan is expected to report robust growth (+10.5% EPS, +5.2% revenue) with estimates revised upwards significantly over the past three months, reflecting its strong year-to-date stock performance (+26.7%). In contrast, Bank of America's Q3 estimates have remained largely unchanged, despite projected strong growth (+16.1% EPS, +7% revenue), suggesting a more stable outlook.

Key Decisions for Investors

• Monitor actual Q3 earnings reports from key Finance and Tech companies to validate the positive revisions trend and assess the sustainability of growth.
• Evaluate sector-specific performance and forward guidance for Q4 and 2025 to inform portfolio allocation, considering the divergence between strong and pressured sectors.
• Assess individual company performance within the Finance sector, such as JPMorgan's continued positive estimate revisions versus Bank of America's stable outlook, for potential alpha generation.
