Core inflation remains high despite the Fed’s aggressive interest-rate hikes. Is now the time to allocate to US small cap stocks?


  • Inflation resistance: In the inflationary 1970s, US small caps outperformed large caps by 4% annually.
  • Compelling value: US small caps are trading at a 45.6% price-to-earnings discount to large caps—well below the historical average.
  • Active stock selection: Prudent active management should, in our view, help navigate times of economic slowdown.

US small caps can, in fact, deliver results in periods of high inflation

From World War II until now, the US has experienced roughly half a dozen episodes in which inflation (as measured by the Consumer Price Index) exceeded 5%. The 1970s isn’t the most recent occurrence of heightened inflation, but the decade does represent the longest stretch of it. For insight into that era, we turn to the work of well-known economist Ken French, which relies on data from the Center for Research in Security Prices (the Russell 2000 Index didn’t exist until 1984). From 1970 through the end of 1979 — when inflation surged from nearly 6% to almost 14% — US small cap stocks returned 9.0% per year, compared with 5.4% for US large caps (Exhibit 1). While this doesn’t necessarily show a correlation between high inflation and small cap outperformance, it does suggest that rising costs present different obstacles to large companies than to their smaller peers — and that some small companies should be better positioned to overcome price inflation.

Small cap companies (those with a market capitalization under $2 billion) tend to have lower margins and may get squeezed by inflated input costs. However, well-managed small companies may be able to pass along price increases to their customers while controlling their own costs and increasing their productivity. We believe that these companies should enjoy stronger earnings growth, since incremental improvements in operating margins will have a more pronounced effect relative to their larger, higher-margin counterparts.

Large and small cap returns begin in 1979. To measure the performance of these categories during the 1970s, the chart is based on the work of Nobel Economics laureate Ken French, which uses data from CRSP to create three portfolios: large cap (top 30% by market cap), mid cap (middle 40% by market cap) and small cap (bottom 30% by market cap). Monthly returns for each portfolio are calculated as the market cap-weighted average return. The results of large and small cap performance using this method are tightly correlated (>97%) with the respective Russell 1000 and Russell 2000 Indexes since index inception (01/01/84–03/31/23). Past performance is no guarantee of future results.

US small caps offer a compelling valuation case

Following sharp compression in earnings multiples year to date, US small cap growth stocks are at their cheapest levels relative to large cap growth stocks since January 2001. Over the long term, the Russell 2000 Growth Index (R2000G) has traded at a 4% average price-to-earnings (P/E) discount to the Russell 1000 Growth Index (R1000G). Today, the P/E ratios for the indexes are 15.02x and 27.64x, respectively, representing a 45.6% discount (Exhibit 2).

Beyond the P/E story, US small caps are trading at discounts to their large cap counterparts across most valuation metrics, except for price to cash flow (Exhibit 3). Since valuation relationships tend to revert to their means, we see potential for significant relative upside for the small cap universe.

Stock selection will be key amid slowing economy

Earnings growth is expected to decline for both small and large companies amid concerns about an economic slowdown and a possible recession this year. In our view, prudent stock selection will play a key role in navigating this environment, particularly within companies and industries that are expected to benefit from strong secular demand trends, such as IT software companies that offer security, accounting or efficiency-enhancing services. We believe that companies with a decisive competitive edge (due to proprietary technology or high barriers to entry), lower debt profiles, and strong cash flow should outperform their respective markets.

As investors continue to grapple with questions about inflation, geopolitical concerns and economic difficulties, we believe US small cap stocks offer attractive characteristics for those pursuing long-term investment goals.


Voya Small Cap Growth Fund was launched on April 4, 2022, after Voya’s acquisition of Tygh Capital Management (TCM) on January 1, 2022. In connection with this acquisition, the Board approved the reorganization of the TCM Small Cap Growth Fund with and into the Voya Small Cap Growth Fund. The historic performance provided prior to the launch date is that of the TCM Fund’s I share. This performance information reflects applicable fee waivers/expense limitations, if any, during the periods shown and absent such fee waivers/expense limitation, performance would have been lower. Performance of other share classes would differ to the extent they have differences in their fees and expenses. As a result of the reorganization, the TCM Fund’s shareholders received Class I shares of the Fund.

The principal risks are generally those attributable to investing in stocks and related derivative instruments. Holdings are subject to market, issuer and other risks, and their values may fluctuate. Market risk is the risk that securities or other instruments may decline in value due to factors affecting the securities markets or particular industries. Issuer risk is the risk that the value of a security or instrument may decline for reasons specific to the issuer, such as changes in its financial condition. More particularly, the strategy invests in smaller companies which may be more susceptible to price swings than larger companies because they have fewer resources and more limited products, and many are dependent on a few key managers.

Investment risks: Investing involves risks of fluctuating prices and the uncertainties of rates of returns and yield inherent in investing. In exchange for higher growth potential, investing in stocks of small companies may entail greater price volatility and less liquidity than investing in stocks of larger companies. Other risks of the Fund include but are not limited to company; growth investing; investment model; market trends; other investment companies; and securities lending risks.
