About PMAPX

The Principal MidCap S&P 400 Index Fund Class R6 is a mutual fund designed to track the performance of the S&P MidCap 400 Index, a widely recognized benchmark representing U.S. mid-cap equities. The fund primarily invests, under normal circumstances, at least 80% of its net assets in the equity securities that make up the S&P MidCap 400. This index includes 400 mid-sized U.S. companies, selected for their market size, liquidity, and sector representation, providing diversified exposure across various industries. The fund’s investment strategy is passive, aiming to replicate the index’s holdings and performance, rather than seeking to actively outperform it. With a broad portfolio spread across hundreds of holdings, the fund minimizes company-specific risk and serves as a core holding for investors seeking exposure to the mid-cap segment of the U.S. equity market. Known for its low expense ratio and competitive fee structure, the fund is structured to appeal to retirement plans and institutional investors, particularly through its R6 share class. This makes it a significant component for those aiming to achieve long-term capital growth through mid-cap U.S. equities.
