This is an actively managed ETF that uses a quantitative methodology to select U.S.-listed mid-cap stocks with exposure to value, momentum, quality and low-volatility factors. A substantial portion of its assets is allocated to mid-cap companies.

It suits investors who want active, factor-based mid-cap exposure that goes beyond simple index tracking.

It is an ETF run by First Trust using an active management approach.

The fund quantitatively combines four investment factors, value, momentum, quality and low volatility, to select mid-cap stocks with strong factor exposure. With active risk management added, factor weightings and holdings are adjusted to market conditions, and the fund does not replicate a fixed index.

• A multi-factor approach combining value, momentum, quality and low volatility
• Mid-cap-focused management combined with active risk management

Assets under management (AUM) stand at $244.2M, and the expense ratio is 0.68% per year.

Its management fee is relatively high compared with passive mid-cap ETFs, and its distinguishing features are active management and multi-factor selection.

Mid-cap factor strategies tend to show varying performance depending on the market phase. They can perform relatively well during periods of strong momentum, but results may be uneven in volatile markets, so the trend is not consistent.

Mid-cap stocks sit in the middle of the risk spectrum between large caps and small caps, and they react sensitively to interest rates and the economic cycle. Fund flows into factor ETFs tend to shift between inflows and outflows depending on market risk appetite and perceptions of factor performance.

Multi-factor active management is the differentiator, but the heavier fee burden compared with passive mid-cap ETFs is a drawback.

The two ETFs shown in the table, DYNF and THRO, are comparison targets that use active factor and thematic rotation strategies, and both involve management team discretion. JMEE is a strategy that emphasizes small and mid caps, and ARKK is a high-risk active ETF focused on disruptive innovation growth. If you want multi-factor exposure at a lower fee, you can consider JHMM, a passive multi-factor ETF, and if you want a simple mid-cap core, low-cost passive alternatives such as IJH and VO are also worth reviewing.

Here are the points to review before investing in AFMC. Because it is an active multi-factor ETF, it is wise to carefully check its fee level, the performance volatility of its factor strategy, trading liquidity and exchange-rate exposure in advance.

The main risks are that factor strategy performance can fluctuate with the market phase and that mid-cap stocks are inherently more volatile than large caps. Active management fees can also have a cumulative impact on long-term returns.

It is a worthwhile choice for investors who want active, factor-based mid-cap exposure. If cost is the priority, the passive mid-cap ETFs IJH and VO are a better fit, while this ETF suits those who value the distinctiveness of a multi-factor active strategy.
