What Is DFIS? Dimensional International Small Cap ETF
Last updated September 2026
Short answer
DFIS is Dimensional International Small Cap ETF, an ETF that tracks Actively managed, no tracked index at a 0.39% expense ratio. DFIS is Dimensional's systematic approach applied to smaller companies in developed markets outside the United States. It follows no index, instead sorting the eligible universe on size, relative price and profitability and holding an extremely wide portfolio built from those rankings. The largest position is 0.5% and the ten largest come to 4.1% of assets, the most evenly spread fund in this group. Industrials at 24% and materials at 14% dominate the sector mix. It charges 0.39%, yields 2.04%, holds $5.8B and dates only to 2022.
DFIS is issued by Dimensional Fund Advisors and tracks Actively managed, no tracked index. It charges a 0.39% expense ratio, holds approximately $5.8B in assets under management, yields about 2.04%, and launched in 2022.
A short history, deliberately noted
The fund launched in 2022, which means its entire life has taken place within a single stretch of monetary policy and dollar behaviour. International small-cap equity is an asset class where the difference between one decade and the next has historically been very large, and a fund with a few years of history cannot show how the strategy behaves across regimes. Dimensional has run comparable mandates for far longer in other vehicles, but this particular fund's own record is short and should be read that way.
That matters more here than it would for a large-cap fund, because smaller foreign companies are more exposed to domestic economic conditions in their home markets and less able to offset weakness through global operations. A Japanese machinery supplier or an Austrian regional bank is a bet on Japan and Austria in a way that Toyota and Allianz are not.
Age also affects practical things. Newer funds trade with wider spreads until liquidity builds, and $5.8B is substantial but not enormous for a strategy that holds a very long list of small foreign securities, each with its own local market hours and settlement conventions.
Systematic rather than index-tracking
Dimensional does not follow a published benchmark. It defines an eligible universe, ranks companies on size, price relative to book value and measures of profitability, and then buys with flexibility about timing. That last part is the point of not tracking an index: a fund obliged to match a benchmark must trade on the dates the benchmark rebalances, whoever is on the other side. A systematic manager can wait, which reduces the cost of implementing the same idea.
The trade-off is that performance will not match any published index and cannot be evaluated against one cleanly. There is no external reference for whether a given month's difference came from the screens working or from implementation choices. Investors are buying a process rather than a rule they can inspect line by line.
The 0.39% fee reflects that. It is well above what plain international small-cap index exposure costs and well below traditional active management. Whether the middle ground is worth it depends on how much value you assign to trading flexibility and to the profitability screen, neither of which shows up in a holdings list.
What international small caps actually are
Industrials at 24% and materials at 14% together account for well over a third of the fund, with consumer discretionary at 14%, financials at 12% and technology at 9% behind them. Small companies outside the United States are heavily weighted toward manufacturing, engineering, mining and industrial supply, not toward the software and consumer platforms that dominate US small-cap growth indices.
The holdings illustrate it. VAT Group makes vacuum valves used in semiconductor manufacturing. Finning International distributes and services heavy equipment. Rexel distributes electrical supplies. Shibaura Mechatronics builds semiconductor processing equipment. Hudbay Minerals mines copper and zinc. Alongside them sit Bawag Group, an Austrian bank, Telecom Italia, Qiagen in diagnostics, Mercari in Japanese online marketplaces and Games Workshop, the British miniatures company.
That mix is genuinely different from a US portfolio, which is the main argument for holding it. It is also more cyclical, more currency-exposed and less liquid. The fund makes no attempt to hedge the currency, so returns to a dollar investor combine local company performance with movements in the yen, euro, Swiss franc, Canadian dollar and sterling among others.

FAQ
Does DFIS track an index?
+
No. Dimensional runs it systematically rather than against a published benchmark, defining an eligible universe of smaller developed-market companies outside the United States and sorting on size, relative price and profitability. The absence of a benchmark gives the manager freedom over trade timing, which is the main practical advantage claimed for the approach.
Why does the 2022 launch date matter?
+
Because the fund's entire record covers one monetary regime and one phase of the dollar cycle. International small caps have historically behaved very differently across decades, and a few years of data cannot show that. Dimensional applies similar processes in longer-running vehicles, but this fund's own history is short and should not be treated as evidence about the strategy over a full cycle.
How diversified is it?
+
Exceptionally. The largest holding is 0.5% and the ten largest come to 4.1% of assets, spread across hundreds of companies in many countries. No individual position can move the fund. That structure is characteristic of Dimensional's approach, which relies on broad exposure to systematic characteristics rather than on concentrated stock selection.
Why are industrials and materials so heavy?
+
Because that is what smaller listed companies outside the United States tend to be. Industrials at 24% and materials at 14% reflect a universe of machinery makers, distributors, engineering firms and miners. The technology and consumer platform businesses that dominate US small-cap indices have far fewer counterparts of comparable size in Europe and Japan.
Is the currency exposure hedged?
+
No. Holdings are denominated in euros, yen, Swiss francs, Canadian dollars, sterling and other currencies, and those exposures reach a US investor unhedged. For smaller companies the effect can be larger than for multinationals, since a domestic manufacturer earns and reports entirely in its home currency without any natural offset.
Is 0.39% expensive?
+
It sits between index and traditional active pricing. Plain international small-cap index funds cost considerably less, and conventional active managers in this space cost more. The premium pays for the profitability screen and for trading flexibility, neither of which is visible in the portfolio. Whether that is worthwhile is a judgement about process rather than about holdings.
What does the profitability screen do?
+
It reduces exposure to companies with weak or negative operating profitability relative to their book value. Applied to small caps, this removes part of the loss-making tail that broad small-cap indices include by default. It is one of the characteristics Dimensional's research treats as a persistent driver of differences in return, and it shapes the portfolio without being a hard exclusion rule.
Who is this fund not for?
+
Anyone who needs a portfolio they can compare against a published benchmark, since there is none. It is also unsuitable for investors uncomfortable with unhedged currency exposure, or with a fund whose sector mix is dominated by cyclical manufacturing and mining. Its natural user wants a distinct, non-US, small-company exposure held for a long period.
What is DFIS's expense ratio?
+
DFIS has an expense ratio of 0.39% per year as of August 2026, charged by Dimensional Fund Advisors and deducted from the fund's value rather than billed to you separately. On a $10,000 position that is roughly $39 a year. Fees compound over time, so on a long-term holding the expense ratio is one of the few return drivers you control. It is worth comparing against other funds that track Actively managed, no tracked index before you choose.
How do I compare DFIS to similar ETFs?
+
Put a few fields side by side: the expense ratio (fees compound over decades), the index or strategy it tracks, the top holdings and how much they overlap with what you already own, the dividend yield, and the AUM, liquidity, and bid-ask spread that affect trading costs. For index funds, tracking error (how closely it follows its index) and tax efficiency matter too. DFIS's figures are above; the full method is in Walnut's guide on how to compare ETFs.
