The Big Picture When It Comes to Small Caps
Small caps have outperformed large caps handily in developed non-US markets and emerging markets.
Talk of the size premium has skewed negative recently over its performance in the US, where small cap stock indices have underperformed their large cap index counterparts over the past two decades. But as is often the case, taking a global point of view improves the picture.
Small caps have outperformed large caps handily in developed non-US markets and emerging markets. As Meat Loaf once sang, “Two out of three ain’t bad.”
The success of the size premium in international markets is a reminder of the value of global diversification. Premiums don’t always move in lockstep across markets, so diversifying globally may increase the reliability of capturing them.

Index descriptions
The Dimensional indices have been retrospectively calculated by Dimensional Fund Advisors LP and did not exist prior to their inception dates. Accordingly, results shown during the periods prior to each index’s inception date do not represent actual returns of the index. Other periods selected may have different results, including losses. Backtested index performance is hypothetical and is provided for informational purposes only to indicate historical performance had the index been calculated over the relevant time periods. Backtested performance results assume the reinvestment of dividends and capital gains.
Dimensional US Small Cap Index was created by Dimensional in March 2007 and is compiled by Dimensional. It represents a market-capitalization-weighted index of securities of the smallest US companies whose market capitalization falls in the lowest 8% of the total market capitalization of the eligible market. The eligible market is composed of securities of US companies traded on the NYSE, NYSE MKT (formerly AMEX), and Nasdaq Global Market. Exclusions: non-US companies, REITs, UITs, and investment companies. From January 1975 to the present, the index excludes companies with the lowest profitability and highest relative price within the small cap universe. The index also excludes those companies with the highest asset growth within the small cap universe. Profitability is measured as operating income before depreciation and amortization minus interest expense scaled by book. Asset growth is defined as change in total assets from the prior fiscal year to current fiscal year. Source: CRSP and Compustat. The index monthly returns are computed as the simple average of the monthly returns of 12 subindices, each one reconstituted once a year at the end of a different month of the year. The calculation methodology was amended on January 1, 2014, to include profitability as a factor in selecting securities for inclusion in the index. The calculation methodology was amended in December 2019 to include asset growth as a factor in selecting securities for inclusion in the index.
