Q2 Earnings Season Sees Market-Wide Expansion Amid Tech Sector Dominance

The Q2 earnings season has been quite impressive, with over 60% of S&P 500 companies already reporting and another 27% on deck this week. The highlight of the season so far has been the 'Magnificent Seven,' a group of tech giants that includes Microsoft, Amazon, Alphabet, Nvidia, and others. These companies have delivered blockbuster results, with blended quarterly earnings up +85.5% from last year on +27.5% higher revenues.

However, it's not just these big-name companies that are driving the market-wide earnings expansion. Q3 estimates are rising across 8 of the 16 Zacks sectors, including Transportation, Finance, Aerospace, Industrials, Utilities, and Construction alongside Tech and Energy. Full-year 2026 estimates are also going up, with total S&P 500 earnings expected to increase +40.8% compared to last year on +13.8% higher revenues.

The Tech sector is a major driver of earnings growth, accounting for 41.2% of all S&P 500 earnings and 45.4% of the index's market capitalization. However, excluding the contribution from Alphabet, Micron, and Nvidia, Q2 earnings for the rest of the Zacks Tech sector would be up +30.3%. The way to read this chart is that one-third of all S&P 500 earnings growth in 2026 is coming from these three Tech companies.
