This is an active ETF in which the management team selects US mid-cap growth companies that combine environmental and social impact credentials with growth potential. It does not track a specific index and instead builds its portfolio through active security selection.

It suits investors who want to add actively managed mid-cap growth exposure beyond a large-cap core while also factoring in an impact perspective.

The ETF is managed by American Century Investments using an active management approach.

From the universe of US mid-cap growth stocks, the fund selects holdings by evaluating revenue and earnings growth alongside environmental and social impact criteria. Rather than mechanically replicating an index, it is an active structure in which the management team adjusts position weights based on its own judgment.

• Security selection that reflects both impact criteria and growth potential
• Active management with no index tracking

Assets under management (AUM) stand at $101.7M, and the total expense ratio is 0.39% per year.

Unlike the large-cap growth ETFs shown in the table, this fund centers on mid-cap growth stocks, so its market capitalization range and exposure differ. Given its active management, its fees are somewhat high.

Mid-cap growth stocks tend to be more volatile than large caps, so performance varies with market risk appetite. Because of the active selection structure, the fund's results can diverge from its benchmark.

Fund flows into impact and mid-cap growth themes tend to fluctuate with the market environment and the interest rate cycle. Interest grows when appetite for growth stocks is strong, and money can flow out when investors turn risk averse.

Its strengths are mid-cap growth exposure and impact-based selection, while the cost burden of active management and volatility are points to watch.

Its market capitalization range is distinct from large-cap-focused active and blue-chip growth ETFs such as JGRO, FBCG, and TCHP shown in the table. Investors looking at the same mid-cap growth segment can also consider index-tracking alternatives such as IWP, VOT, and IJK. IMCG, which specializes in mid-cap growth, and MDY, which broadens exposure across mid caps generally, are also worth comparing.

Here are the points to review before investing in MID. Because it is an active mid-cap growth product, costs, volatility, and management approach should be confirmed in advance, and it is wise to look at both the overlap with a large-cap core and the exposure to the mid-cap segment.

Mid-cap growth volatility and the dispersion of active management results are the main risk factors. In risk-averse phases, declines can be larger than for large caps, and investors should also consider the possibility that performance diverges from the benchmark depending on security selection results.

It is a product worth considering for investors who want to add mid-cap growth exposure with an active, impact-oriented approach. For those who prefer low-cost index exposure, it is also wise to compare alternatives such as IWP and VOT.
