About MPSIX

The Principal MidCap S&P 400 Index Fund Institutional Class is a passively managed mutual fund that seeks to closely replicate the performance of the S&P MidCap 400 Index. This index comprises U.S. mid-cap companies, offering exposure to a diverse range of sectors in the mid-cap segment of the equity market. The fund invests at least 80% of its assets in the stocks that compose the S&P MidCap 400 Index, thus targeting firms that are generally considered to have established operations and growth potential but are not as large as their large-cap counterparts. By tracking an index of 400 stocks, the fund provides broad diversification, helping to manage idiosyncratic risks, with holdings in industries such as industrials, consumer discretionary, healthcare, and financials. The fund typically keeps a relatively small portion of assets concentrated in its largest holdings, further reducing single-company risk. Designed for institutional investors, it offers a cost-efficient vehicle for gaining targeted mid-cap U.S. equity exposure and plays a significant role in portfolio diversification strategies, often complementing both small- and large-cap asset allocations.
