Floating rate debt increases small-cap vulnerability
Sources: Bloomberg and Wells Fargo Investment Institute. Data as of October 13, 2026. Fixed- and floating-rate shares are calculated on debt classified by rate type, which represents a subset of each index’s total short- and long-term debt. An index is unmanaged and not available for direct investment. Past performance is not a guarantee of future results. Excerpted from Investment Strategy report (October 19)Small caps facing a more challenging rate environment
After outperforming for much of the past year, the Russell 2000 Index has recently lost momentum relative to the S&P 500 Index. As a result, U.S. small caps now trail large caps year-to-date, reversing part of their earlier gains. An explanation for the divergence is the recent shift in U.S. monetary policy following the Federal Reserve’s interest rate hike last month.
As seen in the chart, a key distinction between the two indexes is their exposure to floating-rate debt. Russell 2000 Index companies hold about 40% of their rate-classified debt at floating rates, nearly five times the S&P 500 Index share, while 91.5% of S&P 500 rate-classified debt is fixed rate. As a result, small-cap companies are more sensitive to rising interest rates and face greater pressure on debt-service costs.
What it may mean for investors
Higher financing costs can weigh on profitability, cash flow, and future investment for small-cap companies, potentially creating a headwind for earnings growth. We remain unfavorable on U.S. small-caps and recommend using their relatively strong year-to-date gains to rebalance into U.S. large-cap stocks and attractively valued sectors tied to artificial intelligence investment, including the Communication Services, Industrials, and Materials sectors.
Risk Considerations
Each asset class has its own risk and return characteristics. The level of risk associated with a particular investment or asset class generally correlates with the level of return the investment or asset class might achieve. Stock markets, especially foreign markets, are volatile. Stock values may fluctuate in response to general economic and market conditions, the prospects of individual companies, and industry sectors. Small- and mid-cap stocks are generally more volatile, subject to greater risks and are less liquid than large company stocks. Bonds are subject to market, interest rate, price, credit/default, liquidity, inflation and other risks. Prices tend to be inversely affected by changes in interest rates. High yield (junk) bonds have lower credit ratings and are subject to greater risk of default and greater principal risk. Floating rate securities are generally below investment grade quality (“high-yield securities or “junk” bonds) and should be viewed as speculative. Investors should review their ability to assume the risks associated with investments which utilize such securities.
Sector investing can be more volatile than investments that are broadly diversified over numerous sectors of the economy and will increase a portfolio’s vulnerability to any single economic, political, or regulatory development affecting the sector. This can result in greater price volatility. Communication services companies are vulnerable to their products and services becoming outdated because of technological advancement and the innovation of competitors. Companies in the communication services sector may also be affected by rapid technology changes; pricing competition, large equipment upgrades, substantial capital requirements and government regulation and approval of products and services. In addition, companies within the industry may invest heavily in research and development which is not guaranteed to lead to successful implementation of the proposed product. There is increased risk investing in the Industrials sector. The industries within the sector can be significantly affected by general market and economic conditions, competition, technological innovation, legislation and government regulations, among other things, all of which can significantly affect a portfolio’s performance. Materials industries can be significantly affected by the volatility of commodity prices, the exchange rate between foreign currency and the dollar, export/import concerns, worldwide competition, procurement and manufacturing and cost containment issues.
