Should you consider adding State Street SPDR S&P MIDCAP 400 ETF Trust (MDY) to your investment watchlist?

Overview of SPDR S&P MIDCAP 400 ETF Trust (MDY)

For investors seeking comprehensive access to the U.S. mid-cap blend equity market, the SPDR S&P MIDCAP 400 ETF Trust (MDY) is a notable choice. This passively managed exchange-traded fund has been available since May 4, 1995.

Managed by State Street Investment Management, MDY has accumulated over $25.63 billion in assets, positioning it among the largest ETFs focused on the mid-cap blend segment of U.S. equities.

Understanding the Mid Cap Blend Segment

Mid-cap companies typically have market capitalizations ranging from $2 billion to $10 billion. These firms often offer greater growth potential than large-cap companies while generally experiencing less volatility than small-cap stocks. As a result, mid-cap investments can provide a balanced mix of stability and growth.

Blend ETFs, such as MDY, include both growth and value stocks, capturing characteristics of both investment styles.

Fees and Expenses

Expense ratios play a significant role in ETF returns. Over time, funds with lower costs can outperform more expensive alternatives, assuming all other factors are equal.

MDY has an annual expense ratio of 0.23%, which is comparable to similar ETFs in this category.

The fund also offers a 12-month trailing dividend yield of 1.05%.

Sector Allocation and Leading Holdings

While ETFs provide broad diversification and reduce the risk associated with individual stocks, it’s important to review the fund’s specific holdings. Most ETFs, including MDY, are transparent and disclose their portfolios daily.

MDY allocates the largest portion of its assets—about 25.4%—to the Industrials sector. Information Technology and Financials are also among the top sectors represented in the fund.

Key individual holdings include Lumentum Holdings Inc. (LITE), which makes up approximately 1.11% of assets, followed by Ciena Corporation (CIEN) and Coherent Corp. (COHR).

The top ten holdings collectively represent around 7.95% of the fund’s total assets.

Performance and Risk Profile

The goal of MDY is to replicate the performance of the S&P MidCap 400 Index, before accounting for fees and expenses. This index consists of 400 selected U.S. stocks across a wide range of industries.

Year-to-date, MDY has returned about 8.68%, and over the past year (as of 02/26/2026), it has gained roughly 17.15%. During the last 52 weeks, its price has fluctuated between $468.22 and $658.61.

With a beta of 1.05 and a three-year standard deviation of 17.9%, MDY is considered a medium-risk investment. The fund holds approximately 401 stocks, helping to minimize company-specific risk through diversification.

Alternative ETF Options

MDY is rated as a Zacks ETF Rank 3 (Hold), which takes into account factors such as expected returns, fees, and momentum. For those interested in the mid-cap blend space, MDY is a solid choice, but there are other ETFs worth considering.

• Vanguard Mid-Cap ETF (VO): Tracks a similar index, with $95.81 billion in assets and a low expense ratio of 0.03%.
• iShares Core S&P Mid-Cap ETF (IJH): Also follows a comparable benchmark, managing $112.34 billion in assets and charging a 0.05% expense ratio.

Conclusion

Passively managed ETFs like MDY have become increasingly popular among both individual and institutional investors due to their low costs, transparency, flexibility, and tax advantages. They are particularly well-suited for long-term investment strategies.
