Key Takeaways

  • Due to balance sheet concerns, the higher-for-longer interest rate environment has been a significant headwind for the relative performance of U.S. small-cap equities.
  • The market’s expectation of a Fed rate-cutting cycle starting in September 2024 triggered a “catch-up” rotation into small caps in July 2024.
  • Going forward, we think small caps can continue to benefit from gradually easing monetary policy, reasonable economic growth (i.e., avoiding a near-term recession) and attractive valuations.
  • Within our Model Portfolios, we remain modestly over-weight in U.S. mid- and small-cap stocks relative to their larger counterparts.

Throughout 2023 and the first half of 2024, the returns on U.S. small-cap equities significantly lagged behind their larger peers. This performance gap can be attributed to several factors, but one key fundamental driver has been the higher-for-longer interest rate environment and the sensitivity of smaller companies to elevated short-term yields.  

Smaller companies tend to utilize floating rate debt to a much greater extent than larger companies. As highlighted by our colleague Jeff Weniger in a recent piece, in 2023 roughly 30% of small-cap companies’ debt was variable rate, compared to less than 10% for large caps. We identified this risk several years ago, yet the market continuously punished these smaller companies due to concerns around this balance sheet dynamic.

This can be seen in the close relationship between small-cap performance and Fed policy expectations in recent years despite a relatively robust economic environment.

Changes in Fed Policy Expectations and Interest Rates Have Been Highly Correlated to the Relative Performance of U.S. Small Caps vs. Their Larger Counterparts

While it is up for debate whether this market action was justified based on the fundamental impact that higher interest costs had on small-cap companies’ bottom lines, going forward, we see several reasons for optimism.

First, the market is anticipating that a Fed easing cycle could begin as early as September of this year. This spurred a brief, albeit dramatic, rotation into small caps last month, which continued the trend of performance correlation with interest rate implications.

Looking ahead, we think this rotation may have legs, as small caps have historically outperformed larger companies in the 12-month period following the first Fed rate cut in a monetary policy easing cycle.

Lastly, prevailing valuations remain attractive. For virtually the entire post-pandemic environment, small-cap multiples hovered about two standard deviations below their historical median versus large caps and remain there today, providing an attractive entry point for those considering an allocation.

Several factors are contributing to the valuation gap between large and small caps, including the aforementioned interest rate burden, AI enthusiasm—particularly within the large- and mega-cap space—and a residual fear of recession that continues to dissipate.

While the U.S. economy may be showing signs of weakening, small caps are arguably already priced for a recession. In this scenario, we anticipate that unexpected macroeconomic trouble would disproportionately afflict richly valued large caps more than already-discounted small caps.

Should the macro environment continue to signal a soft landing or simply stable economic conditions, small caps may finally enjoy a long overdue catch-up rally. In this scenario, even modest multiple expansion back toward their historical median versus large caps could produce significant gains for an asset class desperately in need of them. For a market that has historically been associated with sky-high multiples during periods of risk-on enthusiasm, today’s measures look surprisingly modest amid a backdrop of impressive large-cap gains.

With these factors in mind, we continue to tilt toward high-quality U.S. mid-caps and small caps within our Model Portfolios. We look to achieve this quality focus through strategies that use static and trend-based observations of return on equity (ROE) and return on assets (ROA) to identify companies that are more profitable and growing earnings faster than the broader universe.
