SPDR S&P 400 Mid Cap Value ETF (MDYV) is an exchange-traded fund that seeks to provide investment results that, before fees and expenses, correspond generally to the total return performance of the S&P MidCap 400 Value Index. The fund employs a passive management strategy to track the market capitalization-weighted index comprising value stocks selected from the S&P MidCap 400 universe, focusing on mid-capitalization U.S. companies exhibiting value characteristics such as low price-to-earnings, price-to-book, and price-to-sales ratios; it holds approximately 296 stocks across sectors including financials (around 21%), industrials, and consumer discretionary, with top holdings such as Flex Ltd., US Foods Holding Corp., and Performance Food Group Company. MDYV offers investors exposure to the mid-cap value segment of the U.S. equity market through shares traded on the NYSE Arca exchange; quarterly dividend distributions; and a low expense ratio of 0.15%, with assets under management of approximately $2.45 billion. Launched on November 8, 2005, and issued by State Street Global Advisors, the fund is headquartered in Boston, Massachusetts, and primarily serves institutional and retail investors seeking diversified mid-cap value equity exposure with no significant geographic operations outside the United States beyond its underlying domestic holdings. In recent developments, State Street Global Advisors, the fund's sponsor, expanded its SPDR ETF suite in September 2025 with the launch of actively managed target maturity bond ETFs, including the SPDR SSGA My2035 Corporate Bond ETF (MYCO) and SPDR SSGA My2031 Municipal Bond ETF (MYMK), enhancing its fixed-income offerings alongside established equity products like MDYV; the fund itself has maintained stable operations with year-to-date returns of approximately 8.19% and one-year returns of 3.92% as of December 2025, amid ongoing portfolio rebalancing to align with the benchmark index.
