It is a passive ETF that tracks an index of US mid-cap growth stocks meeting environmental, social, and governance criteria. By screening holdings on ESG standards and diversifying across mid-sized companies with strong growth potential, it reflects a responsible investing perspective.

It suits growth-oriented investors who want to add an ESG lens to mid-cap growth investing and are willing to tolerate mid-cap volatility.

It is a passively managed (index-tracking) ETF run by Nuveen.

The fund tracks an index of US mid-cap growth stocks that meet environmental, social, and governance criteria. It excludes or underweights companies that fall short of ESG standards and diversifies across mid-sized companies with strong growth potential. The result is a structure similar to a conventional mid-cap growth index that also reflects a responsible investing perspective.

• Mid-cap growth stock exposure with ESG criteria applied
• Holdings screened on environmental, social, and governance standards

Assets under management (AUM) stand at $319.6M, and the total expense ratio is 0.31% per year.

Compared with a conventional mid-cap growth ETF that invests without ESG criteria, the ESG screening standard is the main point of comparison.

US mid-cap growth stocks react sensitively to interest rates, market risk appetite, and the economic cycle. They tend to be strong when investors favor growth stocks and weak when rates rise or value stocks come into favor. Because an ESG index excludes a limited number of stocks, its performance tends not to differ greatly from that of a conventional mid-cap growth index.

Fund flows into ESG mid-cap growth stocks vary with market risk appetite, the rate outlook, and demand for sustainability. When interest in responsible investing rises, money sometimes moves into this group of products. It is also worth noting that performance shifts with interest rates and style rotation.

ESG integration and mid-cap growth exposure are the strengths, while mid-cap volatility, weakness in growth stocks, and tracking differences are considerations.

For mid-cap growth exposure without ESG criteria, direct substitutes include IWP and VOT, and IMCG is another product worth comparing for mid-cap growth exposure. The three products shown in the table, JGRO, NULG, and TCHP, follow active growth, large-cap ESG growth, and blue-chip growth strategies respectively, and differ in market cap and criteria. This ETF is distinguished by its narrower exposure to mid-cap growth stocks that reflect ESG criteria.

Here are the points to review before investing in NUMG. ESG integration and mid-cap growth exposure are its appeal, but mid-cap volatility, weakness in growth stocks, and tracking differences should be checked in advance. It is also a good idea to compare it with mid-cap growth products that operate without ESG criteria.

Rising interest rates, weakness in growth stocks, and mid-cap volatility are the main variables for long-term performance, and ESG screening can make the fund's composition differ from that of a conventional mid-cap growth index. Given the nature of mid-cap stocks, declines can be steep during market crashes.

It is a suitable candidate for growth-oriented investors who want to add an ESG lens to mid-cap growth investing. For mid-cap growth exposure without ESG criteria, consider products such as IWP and VOT, and for ESG mid-cap growth exposure, it is advisable to compare this product alongside them before choosing.
