A Wider Net on Premiums


Even the most patient angler can get frustrated when the fish are refusing to take the bait. Likewise, investors can lose patience when a desired premium doesn’t turn up for years on end. The answer in both cases is to cast one’s net as widely as possible.

I was thinking about this lesson in the context of small cap value performance. Many investors have expressed concern over small cap value stocks underperforming large caps in the US over the 20 years ending in February. Two decades is a long time for an expected premium not to show up, and investor frustration is understandable.

But there are a couple of points to make here. Firstly, this long period of small value trailing large caps is most noticeable in the US and is largely an outlier from a global perspective. In major non-US markets, by contrast, small caps have outperformed large caps over the same period.

Secondly, we know that predicting when and where positive size, value and profitability premiums will appear next is a tough ask. The record shows that the realised volatility of these premiums at the country level has been higher than when considering all countries together.

Like an angler who fishes in more than one spot, the answer is global diversification. Spreading your investments across many countries is an effective tool both in managing idiosyncratic country risk and ensuring you capture positive premiums where and when they occur.

This can help you stay on track with your long-term goals through all kinds of markets.

Index Definitions

The Dimensional indices have been retrospectively calculated by Dimensional Fund Advisors LP and did not exist prior to their index inception dates. Accordingly, results shown during the periods prior to each index’s index 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.


The Dimensional Indices represent academic concepts that may be used in portfolio construction and are not available for direct investment or for use as a benchmark.  Index returns are not representative of actual portfolios and do not reflect costs and fees associated with an actual investment.


Dimensional US Small Cap Value Index was created by Dimensional in March 2007 and is compiled by Dimensional. It represents a market-capitalisation-weighted index of securities of the smallest US companies whose market capitalisation falls in the lowest 8% of the total market capitalisation and whose relative price is in the bottom 35% of the eligible market, or 25% prior to January 1975, after the exclusion of utilities, companies lacking financial data, and companies with negative relative price. 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, 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 amortisation minus interest expense scaled by book. Asset growth is defined as change in total assets from the prior fiscal year to the current fiscal year. Source: CRSP and Compustat.
