Buy Small-Capitalization Stocks for Safety, Outperformance in the Coming Years

Advisor Perspectives welcomes guest contributions. The views presented here do not necessarily represent those of Advisor Perspectives.

Investors in large capitalization indexes now face historically elevated concentration, demanding valuations, and growing influence by leveraged/volatile investment products. In our view, these developments have shifted the relative risk-reward balance toward small-capitalization stocks.

Small-capitalization stocks may now provide greater diversification and less valuation risk than many of the market’s largest blue-chip companies. Moreover, it appears to us that this is just the beginning stages of a change in leadership, and it is possible small-capitalization stocks could outperform large stocks for the next few years.

Volatility Is the Dark Side of Leverage

The increasing use of leveraged and inverse exchange traded funds (ETFs) brings to mind a warning often attributed to Charlie Munger: “There are only three ways a smart person can go broke: liquor, ladies, and leverage.” Munger’s reasoning needs a gender refresh, but the warning about leverage does not.

Industry estimates suggest that U.S.-listed leveraged and inverse ETFs recently held approximately $200 billion in assets, representing close to $500 billion of gross market exposure.¹ That estimate does not include leverage employed through margin accounts, options, futures, and other trading vehicles.

Leveraged and inverse ETFs generally reset their targeted exposure each day. As markets move, the funds must rebalance their portfolios while derivatives’ counterparties may also need to adjust their hedges. During periods of heightened volatility, these transactions can produce procyclical flows that amplify market movements. This risk is potentially more significant today because the 10 largest companies account for close to 40% of the S&P 500. Investors who believe they own a broadly diversified index are therefore unusually dependent on a relatively small group of highly valued companies.
