This is a passive ETF that tracks an index built with the AlphaDEX selection method, which picks U.S. mid-cap stocks with strong growth characteristics and the potential for risk-adjusted outperformance. It seeks exposure that differs from a simple growth index.

By adding quantitative selection to U.S. mid-cap growth stocks, it aims for differentiation, making it suitable for growth-oriented investors willing to accept mid-cap volatility.

It is an ETF managed by First Trust using a passive (index-tracking) approach.

Using the AlphaDEX selection method, which scores U.S. mid-cap stocks on growth-related metrics, the fund picks stocks with strong growth characteristics and sets their weights. Because stocks are selected on a quantitative score rather than market-cap weighting, it offers differentiated exposure compared with a simple mid-cap growth index.

• Mid-cap growth selection based on AlphaDEX scores
• Quantitative exposure that differs from market-cap weighting

Assets under management (AUM) are $549.4M, and the total expense ratio is 0.73% per year.

Unlike market-cap-weighted growth ETFs, its quantitative selection and mid-cap weighting can cause performance to diverge from the market, and its volatility tends to be somewhat higher.

Mid-cap growth stocks react sensitively to the economic cycle, risk appetite, and investor preference for growth styles. They can be strong when growth stocks are in favor, but they may lag in periods of rising interest rates or value-led markets, so results depend heavily on the market style.

Money tends to flow into mid-cap growth ETFs when interest in mid-cap growth and quantitative selection rises, while inflows can slow when rates rise or preference for value stocks strengthens.

Its strength is mid-cap growth exposure enhanced by quantitative selection, while its weaknesses are volatility, performance dispersion, and turnover.

The VUG, IWF, and IVW shown in the table are market-cap-weighted ETFs focused on large-cap growth, so their market-cap range and weighting method differ. For more mid-cap growth exposure, you can also compare VOT (mid-cap growth), IWP (Russell Mid-Cap Growth), and IMCG (mid-cap growth). These funds differ in selection method, market-cap range, and fees, so it is best to choose according to your investment style.

Here are the points to review before investing in FNY. As a quantitatively selected mid-cap growth ETF, it is important to check volatility, performance dispersion, turnover, and fee level in advance.

Its weighting toward mid-cap growth stocks makes volatility somewhat large, and quantitative selection can create performance gaps versus the market. You should also consider that it may lag in periods of rising interest rates or value-led markets.

This is a passive ETF suited to growth-oriented investors who expect differentiation from adding quantitative selection to U.S. mid-cap growth stocks. If you want simple market-cap weighting, a standard growth ETF may be the better choice, while FNY can be an alternative if you want quantitative mid-cap growth selection.
