International small cap

🇺🇸

Since US large-cap stocks and international large-cap stocks have high correlation, some investors look for international small cap mutual funds and ETFs to further diversify their portfolios. This page is intended to present a summary of international small cap mutual funds and ETFs.

Selection
Since new ETFs open regularly this list is not complete. It includes the major ETFs, but excludes some which are very expensive, very small and thus expensive to trade, or very new.

Tracking error
Since these ETFs trade in illiquid stocks, many of them only sample the indexes they track, and they incur transaction costs when the indexes change. Therefore, the ETFs do not necessarily track the index well; deviations of 1% annually are common. EWX underperformed its index by about 3% annually through 2012, but was close in 2013-2015 and outperformed the index in 2016-2018. (This tracking error is based on the net asset value; when you buy or sell an ETF, this may add to the tracking error because these ETFs frequently trade at a premium or discount to net asset value.)

Tax efficiency
Vanguard International Explorer Fund has been very tax inefficient at least for the past 10 years, and since it is actively managed, it is likely to remain tax-inefficient,  You should strongly consider holding it in a tax-advantaged account.

Small-cap international ETFs tend to distribute more capital gains than other ETFs, possibly because there is less creation/redemption activity. Some foreign countries, particularly emerging markets, do not allow in-kind redemptions, eliminating the tax benefit from the redemption process. Small-cap ETFs should be less likely to distribute gains after several years of operation, because the redemption process is more effective at reducing gains when shares have been purchased at a wide range of prices. As of 2016, only the SPDR ETFs GWX and EWX have distributed gains after the second year.

GWX has has the largest distributions; it distributed a 1.5% short-term gain in its first year (2007), an 0.8% long-term gain in 2011, a 2.7% short-term and 7.5% long-term gain in 2014, an 0.5% short-term and trivial long-term gain in 2015, an 0.8% short-term and 0.5% long-term gain in 2016, and a 2.0% short-term and 0.9% long-term gain in 2019. EWX distributed a 1.5% short-term gain in its second year (2009), a 2.1% short-term and 0.5% long-term gain in 2010, and a 1.3% short-term and 2.2% long-term gain in 2011. VSS distributed a 0.7% short-term gain in its first year (2009) and 0.4% short-term and 0.4% long-term in its second year (2010). DLS distributed an 0.8% short-term gain in its second year (2007).

Independent of capital gains, DLS and DGS are likely to have higher tax costs than the other ETFs, because their indexes overweight stocks with a higher dividend yield.

Trading costs
Many of the ETFs above are thinly traded, and even those which have fairly high volume have larger-than-average bid/ask spread because the value of the underlying stocks is more difficult to estimate.

Underlying securities
The products above have quite different sets and weights of underlying securities. Because of different definitions of developed and emerging markets, two indexes in the same market segment may have different country holdings. Even within the same countries, market-cap-weighted indexes have different country weights because of different definitions of small-cap by country. You are strongly advised to read the prospectus of each product and, if necessary, do additional research before investing in any of the products above.
