The S&P 500 fourth-quarter returns in midterm election years average 5.5%, and investors should maintain exposure to third-quarter market leaders rather than taking early profits, according to CFRA Chief Investment Strategist Sam Stovall. Speaking on CNBC's "The Exchange" on Monday, Stovall shared historical performance data as the S&P 500 dropped 0.77% to close at 7,683.69 under pressure from climbing bond yields.
Key Takeaways
- Historical Q4 Rally: Fourth quarters in midterm years average 5.5% gains and turn positive 75% of the time following a strong Q3.
- 2026 Market Metrics: The S&P 500 is up over 2% for Q3 and more than 12% year-to-date in 2026 ahead of Wednesday's close.
- Low-Debt Sector Strength: Sectors with low net debt relative to EBITDA—led by energy, healthcare, technology, and communication services—outperformed during Q3.
- Surging Yield Environment: The 10-year Treasury yield spiked to 5.23% on Friday, its highest reading since June 2007, up from 3.99% in late February.
Historical Midterm Trends Favor Holding Strong Sectors
Historically, second and third quarters in midterm election years deliver sluggish or dismal market returns. However, when the S&P 500 posts a positive third quarter, fourth-quarter gains follow in 75% of historical instances. With the index up over 2% in Q3 and more than 12% for 2026, Stovall dismissed concerns that recent momentum exhausted fourth-quarter upside potential.
"Following a strong Q3, you want to let your winners ride," Stovall explained during his CNBC interview. He noted that while a weak Q3 typically prompts a strategy of buying the three worst-performing sectors, a solid third quarter rewards sticking with established market leaders.
Balance Sheet Quality Drives Sector Rotation
Recent market leadership was heavily dictated by balance sheet strength, specifically companies maintaining lower ratios of net debt to EBITDA (earnings before interest, taxes, depreciation, and amortization). Concerns over macroeconomic conditions and rising Treasury yields spurred investor rotation into resilient sectors.
Energy, healthcare, technology, and communication services posted the strongest results. Technology accounts for nearly 40% of the S&P 500 market capitalization, while adding communication services brings that share to approximately half the index. Furthermore, elevated energy markets boosted the valuation of proven oil reserves for major producers like Exxon and Chevron. Conversely, industrials, real estate, and utilities lagged behind. Similar macro headwinds from elevated energy prices and interest rates have also created broad risk-off sentiment across related markets, where rising oil and yields weigh on sentiment.
Why It Matters
Stovall's historical analysis highlights how corporate debt exposure dictates equity performance when interest rates stay high. By focusing on balance sheet durability and low debt-to-EBITDA metrics, institutional capital is positioning itself to weather tight monetary policy while participating in seasonal year-end strength. Unless macroeconomic headwinds ease rapidly, high-margin, low-debt technology and energy majors are likely to remain the primary drivers of index performance through the end of the year.
