Signals & Noise: Why small & mid-caps are leading the 2026 market rally – and what’s next

Macro Outlook & Performance Thesis:

• U.S. Small & Mid-Caps (SMID) are projected to outperform Mega-Caps in 2026 as earnings growth, rather than valuation expansion, drives market returns.
• Earnings growth is expected to accelerate in the second half of 2026, driven by a recovery in manufacturing and a multi-year capital expenditure cycle.
• SMID segments are identified as less crowded and less expensive than Mega-Cap counterparts, positioning them to benefit from reshoring trends.
• The ISM manufacturing indicator recently expanded into growth territory, correlating more strongly with the Russell 2000 than in previous years.
• Higher oil prices are viewed as supportive for the Russell 2000 due to its sector weighting favoring energy beneficiaries over hurt sectors.
• Historically, small caps have outperformed large caps within equities during stagflationary environments.

Valuation Metrics:

• While broad U.S. equities trade above historical averages, SMID caps remain the least expensive segment of the market.
• The Russell 2000 and Russell Mid-Cap indices trade at approximately 17x forward consensus earnings.
• The Russell 1000 (Large Cap) index trades at 21x forward earnings, highlighting a valuation gap.
• The relative multiple of small-to-large and mid-to-mega caps remains well below historic averages, suggesting continued relative value.

Federal Reserve & Interest Rate Sensitivity:

• The Russell 2000 has become increasingly sensitive to Fed expectations since 2022 due to higher leverage, greater floating-rate debt, and more short-term debt maturation than large caps.
• Estimated refinancing risk is elevated, with a higher proportion of small-cap debt coming due over the next five years.
• Modeling suggests every 25 basis point Fed rate cut could benefit Russell 2000 operating earnings by approximately 2%.
• Market pricing currently reflects rate cut expectations for 2026, though recent shifts have priced in potential hikes.
• Despite rate sensitivity, small caps have outperformed in 2026, indicating a decoupling of price from Fed expectations driven by upward earnings revisions.
• Bank of America economists project the Fed will hold rates steady through 2026, with cuts beginning partway through 2027.
• If market pricing shifts toward further Fed hikes, the investment case for small caps would become less compelling.

Geopolitical & Risk Factors:

• Increased geopolitical risk is identified as a volatility driver that typically negatively impacts small caps.
• Scenario analysis suggests that if the Strait of Hormuz reopens and inflation remains sticky, small caps could benefit if markets price in a less hawkish Fed stance to ease refinancing concerns.
• Investors are advised to focus on less levered small caps with low refinancing risk given the current monetary backdrop.

Sector & Stock Selection Opportunities:

• Financials (specifically small cap) and Energy (specifically mid cap) are ranked as top sectors, aligning with a preference for value over growth during profit recoveries.
• Small-cap healthcare presents a new opportunity after poor performance in prior years, supported by picking M&A activity and improving stock quality.
• The median age of small-cap biotech stocks has increased to eight years, compared to three to four years in 2021, indicating a shift toward more mature, profitable companies.
• Preferred stock characteristics include exposure to manufacturing recovery, capital expenditure beneficiaries, positive earnings growth revisions, and potential AI-driven efficiency gains.
• Small caps are noted as the most labor-intensive market segment, making them particularly susceptible to AI efficiency applications.

Methodology & Coverage:

• Bank of America Global Research covers approximately 1,000 U.S. small and mid-cap stocks, offering granular stock selection opportunities.
• Proliferation of ETFs in the SMID space now allows investors access to various styles, indices, and thematic exposures.
• The strategic conclusion favors SMID caps over Mega-Caps but emphasizes selectivity and monitoring of the Fed and manufacturing macro trends.
