This is a systematic core ETF that tracks the broad developed-market stock universe outside the US while placing extra weight on factors such as small caps, undervalued stocks and high profitability. It holds a wide range of securities, giving it broad country and sector diversification.

It suits investors who want to diversify across developed markets outside the US while seeking long-term, factor-driven excess returns.

It is an actively managed ETF run by Dimensional.

The fund holds the full developed-market universe outside the US broadly, while applying a factor tilt that overweights small-cap, undervalued and high-profitability stocks relative to the market. A distinguishing feature is that the manager uses discretion to account for elements such as short-term price momentum and trading costs in order to improve efficiency.

• A combination of broad diversification and factor tilts
• Systematic managerial discretion rather than index replication

Assets under management (AUM) stand at $18.3B, and the total expense ratio is 0.18% per year.

The fund moves with developed markets outside the US, and volatility appears depending on exchange rates, the global economy and the interest rate environment. The effect of its factor tilts tends to show up over the long term rather than the short term.

Fund flows are driven by demand to diversify away from US-concentrated assets and by demand for diversified developed-market core holdings. It is a category that has drawn steady attention from an asset allocation perspective among investors looking to raise their global diversification.

Broad diversification and factor-based management are its strengths, while currency exposure and the volatility specific to non-US markets are its drawbacks.

DFIC and DFAX, shown in the table, are international and global diversified ETFs from the same Dimensional family, and they differ in whether the US is included and in the strength of their factor tilts. If you want a higher dividend orientation, VYMI and IDV are also worth comparing, and if you prefer an emphasis on dividend growth, VIGI is another candidate. Additionally, if you are looking for a low-fee, broad developed-market core, you can consider IEFA, and if you want diversification across the entire non-US market, you can also review VXUS.

These are the points to review before investing in DFAI. The concept of developed-market diversification outside the US is clear, but its factor characteristics, exposure to many currencies and fee level all affect long-term performance, so they should be confirmed in advance.

Periods in which the factor tilts lag the market can run long, and exposure to many currencies means exchange rate swings directly affect returns. Policy and political shifts in non-US markets are also a source of volatility.

It is a core holding suited to long-term investors who want to diversify across developed markets outside the US on a factor basis. If you want global diversification that includes the US, comparing it with DFAX is recommended, and if you want a simple, low-fee developed-market core, comparing it with IEFA is recommended.
