This is an actively managed US equity ETF run by Dimensional Fund Advisors. It invests in companies that meet environmental, social, and governance (ESG) sustainability criteria, with higher weights in small-cap, value, and high-profitability factors. It does not track a specific index and selects securities using its own model.

It suits long-term investors who want to reflect ESG values in their investments while still pursuing systematic, factor-based diversification.

Dimensional Fund Advisors launched this actively managed ETF in 2022.

The portfolio is built by assigning small-cap, value, and high-profitability factor weights to US companies that pass ESG sustainability screening. Rather than simply tracking an index, it adjusts position weights using its own model, and it keeps trading costs low through very low turnover.

• A hybrid strategy that applies ESG criteria and factor investing (small-cap, value, high profitability) at the same time
• More than 1,800 holdings, providing broad diversification and low single-stock and sector concentration risk

Assets under management (AUM) stand at $2.4B, and the expense ratio is 0.15% per year.

Its fees are low relative to the category average, so it is cost-efficient even for an actively managed ETF. Liquidity is more limited than that of comparable large passive ETFs, but it is adequate for ordinary long-term trading.

During periods of strength in US growth stocks, the fund's relatively low weighting in large-cap growth names may cause it to lag the category average, while the factor-weighting effect can show up when value and small-cap stocks are in favor. The ESG filter tends to reduce exposure to the energy and materials sectors.

As interest in ESG investing persists over the long term, the fund continues to draw steady inflows from institutional and individual investors who prefer factor-based management. Its assets are growing amid the broader expansion of the sustainability-themed ETF market.

Its strength is the combination of ESG values and factor diversification, while its weaknesses are relative performance in markets concentrated in large-cap growth stocks and the risk of changes in how ESG is defined.

Among the products in the table, DYNF is a factor-based US equity ETF managed by BlackRock that differs in the scope of ESG application and in how factors are constructed, and THRO is a dividend-focused ETF that reflects ESG criteria and offers a different choice for income-oriented investors. ARKK is an actively managed ETF concentrated in innovative growth stocks, so its portfolio character is entirely different, and JMEE is a US equity ETF that applies ESG principles. In addition, ESGU (tracking a broad ESG index) and SUSA (tracking an MSCI ESG index) are alternatives within the same ESG theme, and from a factor-investing perspective, DFSV (Dimensional's small-cap value ETF) is also worth considering.

These are the key items to review when considering an investment in DFSU. Because it is an actively managed ETF, it is important to understand its management approach, ESG criteria, and cost structure thoroughly in advance.

Expected returns may differ if ESG criteria change or if the factor strategy loses its effectiveness. Relative performance may lag in markets dominated by large-cap growth stocks, and by the nature of active management, it adds uncertainty about the manager's judgment compared with passive ETFs.

It is a suitable choice for long-term investors seeking ESG values and factor-based diversification together. If you want a purely low-cost passive option, consider ESGU or SUSA, and if you want to focus more on factor investing, it is worth comparing it with DFSV.
