Micron and Nvidia Drive Broad S&P 500 Earnings Growth
Micron and Nvidia are central to the strongest broad-based earnings expansion in recent years, with S&P 500 profits projected to rise 24.0% year-over-year.
Micron Technology and Nvidia are driving the strongest broad-based earnings expansion in recent years for the S&P 500. According to Zacks Investment Research, total index earnings are projected to increase 24.0% year-over-year, supported by an 11.3% rise in revenues. This performance marks the eighth consecutive quarter of double-digit growth, with 14 of the 16 Zacks sectors expected to report positive earnings gains.
The tech sector’s contribution is particularly significant, as excluding Micron and Nvidia would reduce the sector's Q3 earnings growth from 42.0% to 23.7%. This dependency highlights how these two semiconductor firms anchor the broader market’s profit trajectory amidst a favorable demand environment for chipmakers.
Tech Sector Relies on Chipmakers
The semiconductor industry continues to outperform within the tech sector, with Micron and Nvidia accounting for a substantial portion of the group's growth. The Zacks report notes that the tech sector remains a major contributor to aggregate earnings, with overall index growth dropping to 14.5% if the sector is excluded. This concentration of earnings power in specific hardware companies underscores the continued strength of the AI and data center buildout.
Energy Drives Estimate Revisions
Since the start of Q3, the energy sector has seen the most pronounced upgrade to its earnings outlook, reflecting elevated oil prices driven by geopolitical tensions in the Persian Gulf. Other sectors with positive estimate revisions include aerospace, industrial products, autos, transportation, finance, and utilities. Notably, the aggregate revisions trend remains positive even if the positive adjustments to energy or tech are removed, indicating broad-based confidence in corporate profitability.
Forward Estimates Remain Strong
The favorable revisions trend extends into the final quarter of the year, with mostly the same sectors enjoying positive estimate changes. This sustained momentum supports the current expectation of robust growth, as only the conglomerates sector is projected to see lower Q3 earnings relative to the prior year. The data suggests that corporate earnings growth is not limited to a few outliers but is supported by a wide array of industrial and financial activities.
