Valuing the Smaller Things
Key Insights
- While U.S. value and small- and mid-cap stocks have been out of favor recently, we believe exposure to these styles can improve portfolio durability.
- Historically, small- and mid-cap value have played important return-enhancing and risk-reducing portfolio roles, helping to reduce downside market exposure.
- History also suggests that investors who miss the initial months of a small value outperformance cycle may sacrifice a large share of that outperformance.
The dynamic nature of capital markets means that generating durable investment results requires thoughtful portfolio design and ongoing revalidation of allocations through time. One key challenge is that markets evolve, and as a result, investment style leadership (such as the equity value style versus the growth style) tends to rotate over time. Historically, these cycles have lasted several years and have often prompted investors to question if an out‑of‑favor style will ever work again.
For most of the past decade, two equity styles—U.S. value and smaller capitalization (including both small‑ and mid‑cap stocks)—have been out of favor. However, while the shorter‑term performance of these styles has been challenged, longer‑term data (Figure 1) show that both approaches historically have been strong drivers of positive returns and have accounted for a meaningful portion of the broad U.S. equity market, equaling approximately 15% of the Russell 3000 Index as of March 31, 2020.1

The goal of this paper is not to validate the continued existence of any specific return premia for small‑ and mid‑cap value stocks. Rather, we focus here on the risk‑based case, hopefully demonstrating to investors the benefits of ensuring that their portfolio positioning is properly diversified through a thoughtful reexamination of their U.S. equity style and size exposures.
To help illustrate possible negative consequences of under‑diversification, we begin our analysis by reexamining the strategic allocation case for small‑ and mid‑cap value stocks, then take a closer look at some of the key attributes of these investment styles.
Our process seeks to avoid undesired structural bias caused by elevated (or reduced) exposure to particular investment styles..
Our Portfolio Construction Principles
We believe that strategic asset allocation is the most important driver of outcomes over time for many multi‑asset portfolios and that equity allocations should be broadly diversified across regions, sectors, capitalizations, and styles in an effort to distribute and mitigate overall portfolio risk.2 Unless we have a particular investment objective, we tend to design strategic asset allocations that are style‑ and size‑neutral relative to broad market benchmarks like the Russell 3000 Index. There are two key reasons for this practice:
- Size: Market capitalization weights essentially represent investors’ consensus view of company valuations, and thus, in our view, are reasonable starting points in the absence of any particular view or objective.
- Style: Our process seeks to avoid undesired structural bias caused by elevated (or reduced) exposure to particular investment styles relative to the most commonly used core benchmarks.

Important Information — Hypothetical Portfolio
The information presented herein for the hypothetical portfolio is hypothetical in nature and is shown for illustrative, informational purposes only. It does not reflect the actual returns of any portfolio /strategy but rather a theoretical blend of the indicated benchmarks. The assumption of constant benchmark weights has been made for modelling purposes and is unlikely to be realized. The hypothetical portfolio does not reflect the impact that material economic, market or other factors may have on weighting decisions. If the weightings change, results would be different. Transaction costs, taxes, and other potential expenses, are not considered and would reduce returns. Actual results experienced by clients may vary significantly from the hypothetical illustrations shown. Data shown for the hypothetical portfolio is as of the dates shown and represents the manager’s analysis as of that date and is subject to change over time.
