The SPDR S&P MidCap 400 ETF Trust (MDY) is an exchange-traded fund designed to track the performance of U.S. mid-cap companies. The ETF is managed by State Street Global Advisors (SSGA) and trades under the ticker MDY on the NYSE Arca.

Classified as an equity ETF, the fund provides exposure to the mid-cap segment of the U.S. stock market, which consists of companies that generally fall between smaller growth-oriented businesses and large, well-established corporations.

The ETF follows a passive management approach and seeks to replicate the performance of the S&P MidCap 400 Index, a benchmark composed of 400 mid-sized U.S. companies selected according to liquidity, sector representation, and financial viability criteria.

Diversification and sector exposure

MDY provides exposure primarily associated with:

• Mid-cap companies.

• Industrials.

• Financial services.

• Consumer discretionary.

• Technology.

• Healthcare.

• Real estate.

• U.S. domestic economy.

The portfolio includes companies across a wide range of industries, providing diversified exposure to businesses often associated with growth, expansion, and increasing operational scale.

The ETF’s performance is closely tied to the mid-cap segment, which has historically exhibited characteristics distinct from both large-cap and small-cap equities. Many of these companies generate a significant portion of their revenue domestically and may benefit from strength in the U.S. economy.

Structure and costs

MDY shares trade on the secondary market on the NYSE Arca during regular trading hours. Share creation and redemption occur through authorized participants, a mechanism intended to help align the ETF’s market price with its net asset value (NAV).

The fund charges a management fee as outlined in its prospectus and does not apply a performance fee. Dividends received from portfolio holdings may be distributed periodically to shareholders according to the fund’s distribution policy.

Because it invests in mid-cap companies, the ETF may experience greater volatility than strategies focused exclusively on large-cap stocks, although it generally exhibits lower volatility than portfolios concentrated in small-cap equities.
