This is an active ETF that selects stocks from a US small and mid cap universe using volatility, correlation, profitability, and valuation metrics. Its diversification-weighted design seeks to deliver excess returns over the index.

It suits investors who want diversified exposure to US small and mid cap stocks along with an active strategy that differs from market-cap-weighted indexes.

The ETF is managed by Intech using an active management approach.

The fund analyzes volatility, correlation, profitability, and valuation across the US small and mid cap universe to select stocks, then builds its portfolio using a diversification-weighted approach. Rather than relying on market-cap weighting, it uses weights that maximize diversification benefits, pursuing excess returns over the index through an active strategy.

• Diversification-weighted design based on volatility and correlation
• Active stock selection within small and mid cap stocks

Assets under management (AUM) stand at $130.0M, and the Expense Ratio is 0.35% per year.

Compared with traditional market-cap-weighted small and mid cap index ETFs, it takes a different management approach by applying active selection and diversification weighting.

Since its launch, assets under management have grown quickly, drawing market attention. Given the nature of small and mid cap stocks, volatility tends to be higher than for large caps, and returns are affected by interest rates, the economic cycle, and earnings seasons.

Demand for active small and mid cap strategies has kept inflows coming. However, the small and mid cap category is more sensitive to changes in trading conditions than large caps, so fund flows can fluctuate depending on the market phase.

Its strength is a differentiated active strategy built on diversification weighting, while small and mid cap volatility and active management costs are the drawbacks.

The two ETFs shown in the table, HELO and FHEQ, are equity strategies with an added hedge overlay. Others, such as the large-cap core active INFO and the tail-risk-focused CAOS, are strategy-driven products with different management approaches, and their exposure and strategy differ from the small and mid cap diversification-weighted active approach of SMDX. Meanwhile, as low-cost passive alternatives in the same US small and mid cap space, investors can also consider core ETFs such as IJR, which tracks S&P 600 small caps, IJH, which tracks mid caps, and VXF, which offers exposure to broad small and mid cap stocks.

Here are the points to review before investing in SMDX. As an active small and mid cap ETF, it is wise to check in advance its volatility, fee costs, and the durability of its diversification-weighted strategy's performance, and to compare it with passive core ETFs as well.

The main risks are the high volatility of small and mid cap stocks and the uncertainty of the active strategy's performance. In volatile markets, drawdowns can be larger than for large caps, and the diversification-weighted model does not always beat the index.

It is an option worth considering for investors who want to approach US small and mid cap stocks with a differentiated active strategy. For simple, low-cost exposure, passive core ETFs such as IJR and IJH are more suitable, while SMDX fits those who want a diversification-weighted active strategy.
