Description

The SPDR S&P MidCap 400 ETF (MDY) holds roughly 400 U.S. mid‑cap stocks, concentrating on companies headquartered in North America and weighted by market capitalization, with the largest sector allocations in Industrials, Financials, Information Technology, Health Care and Consumer Discretionary. Its investment approach is to fully replicate the S&P MidCap 400 Total Return Index, providing broad, low‑turnover exposure to the mid‑cap segment of the U.S. equity market. This fund is appropriate for investors who want diversified exposure to mid‑size American companies as a complement to large‑cap or small‑cap holdings, seeking potential growth and a balance between risk and return without focusing on specific sectors or regions.
