It is a core ETF that holds US-listed stocks broadly on a market-cap-weighted basis, tracking the performance of the overall US market. In line with Dimensional's investment philosophy, it adjusts holding weights by also considering factors such as price, size, and profitability.

It suits core-holding investors who want low-cost, long-term diversification across the US market and who value tax efficiency.

It is an actively managed ETF run by Dimensional.

The fund holds US large-, mid-, and small-cap stocks broadly, while adjusting holding weights by also considering factors such as price, size, and profitability, as well as liquidity and momentum. It also runs a tax-management strategy that delays and reduces realized capital gains, for example by selling losing positions to offset gains, in order to improve after-tax returns.

• Weight adjustments that reflect factors
• Tax-efficient management that takes after-tax returns into account

Assets under management (AUM) stand at $21.9B, and the expense ratio is 0.09% per year.

Over the long term, the fund has shown an upward trend in step with US economic growth, while short-term performance is affected by interest rates, earnings seasons, and broader market swings. Given its broad market exposure, it tends to follow the overall market trend rather than individual stocks.

Fund flows have been relatively steady alongside demand for core assets, and long-term capital that favors low costs and tax efficiency has been coming in. During periods of market volatility, its broad diversification can also soften the impact of shocks in individual sectors.

Its strengths are broad diversification, a low expense ratio, and tax efficiency. The point to watch is that, because of its factor-based management, performance may differ from a purely index-tracking fund.

Among the comparison targets shown in the table, DFAC is a core ETF also managed by Dimensional and differs in the intensity of its factor management, while VIG and SCHD are ETFs focused on dividend growth and high dividends, so their strategies differ from this fund's pursuit of broad market exposure, and their expense ratios also differ. Direct substitutes offering the same total US market exposure include ITOT, the low-cost broad core fund SCHB, VTI for the total US market, and the large-cap-focused VV, all of which are worth considering as well. These funds differ in expense ratio and management approach, so the choice depends on your preferences for cost and factor exposure.

Here are the points to review before investing in DFUS. Although it is a broad core asset, it helps long-term holding decisions to check in advance the expense ratio, the factor-based management approach, large-cap concentration, and currency exposure.

Factor-based weight adjustments can cause performance to differ from a pure index, and because of market-cap weighting, swings in large caps and exchange rates are the main drivers of short-term volatility. During market crashes, even a core asset can suffer significant short-term losses.

It is a core option suited to long-term investors who want low-cost diversification across the US market along with tax efficiency and factor-based management. If you prefer pure index tracking, it is also worth comparing broad core ETFs such as ITOT and VTI.
