About STMGX

The American Beacon Stephens Mid-Cap Growth Fund Investor Class is a mutual fund that seeks to deliver long-term capital growth by investing primarily in the equity securities of medium-sized U.S. companies. Managed by Stephens Investment Management Group, the fund maintains a focused strategy that emphasizes selecting mid-cap growth companies believed to have above-average earnings growth potential. The management team leverages fundamental analysis to identify opportunities within the mid-cap segment—an area considered by the managers to be less efficiently priced and home to some of the fastest-growing businesses in the public markets. The fund typically invests at least 80% of its net assets in mid-cap stocks, spanning sectors such as technology, healthcare, industrials, and consumer goods. The portfolio is diversified but tends to have concentrated positions in companies demonstrating consistent growth characteristics. As a mid-cap growth fund, it plays a vital role in offering investors exposure to dynamic businesses that may occupy a space between the stability of large-caps and the rapid expansion opportunities of small-caps. The fund is designed for investors seeking exposure to potential capital appreciation from innovative and expanding U.S. businesses.
