Read MoreHide Full Article

Launched on 11/08/2005, the SPDR S&P 400 Mid Cap Growth ETF (MDYG - Free Report) is a passively managed exchange traded fund designed to provide a broad exposure to the Mid Cap Growth segment of the US equity market.

The fund is sponsored by State Street Global Advisors. It has amassed assets over $1.66 billion, making it one of the larger ETFs attempting to match the Mid Cap Growth segment of the US equity market.

Why Mid Cap Growth

Mid cap companies, with market capitalization in the range of $2 billion and $10 billion, offer investors many things that small and large companies don't, including less risk and higher growth opportunities. These types of companies, then, have a good balance of stability and growth potential.

While growth stocks do boast higher than average sales and earnings growth rates, and they are expected to grow faster than the wider market, investors should note these kinds of stocks have higher valuations. Something to keep in mind is the higher level of volatility that is affiliated with growth stocks. When you consider growth versus value, growth stocks are usually the clear winner in strong bull markets but tend to fall flat in nearly all other environments.


Investors should also pay attention to an ETF's expense ratio. Lower cost products will produce better results than those with a higher cost, assuming all other metrics remain the same.

Annual operating expenses for this ETF are 0.15%, making it one of the least expensive products in the space.

It has a 12-month trailing dividend yield of 1.11%.

Sector Exposure and Top Holdings

It is important to delve into an ETF's holdings before investing despite the many upsides to these kinds of funds like diversified exposure, which minimizes single stock risk. And, most ETFs are very transparent products that disclose their holdings on a daily basis.

This ETF has heaviest allocation to the Industrials sector--about 18.70% of the portfolio. Information Technology and Consumer Discretionary round out the top three.

Looking at individual holdings, Steel Dynamics Inc. (STLD - Free Report) accounts for about 1.85% of total assets, followed by Carlisle Companies Incorporated (CSL - Free Report) and Neurocrine Biosciences Inc. (NBIX - Free Report) .

The top 10 holdings account for about 11.54% of total assets under management.

Performance and Risk

MDYG seeks to match the performance of the S&P MidCap 400 Growth Index before fees and expenses. The S&P MidCap 400 Growth Index measures the performance of the mid-capitalization growth sector in the U.S. equity market.

The ETF has added roughly 4.82% so far this year and is down about -3.26% in the last one year (as of 01/24/2023). In the past 52-week period, it has traded between $59.32 and $76.65.

The ETF has a beta of 1.08 and standard deviation of 29.40% for the trailing three-year period, making it a medium risk choice in the space. With about 237 holdings, it effectively diversifies company-specific risk.
