- American Century Investments Focused Dynamic Growth Fund - Investor Class (ACFOX) is an open-end mutual fund managed by American Century Investments that seeks long-term capital growth by investing primarily in common stocks of large-cap growth companies exhibiting high growth rates, competitive advantages, and higher profitability, with a focus on industry-innovating firms; the portfolio typically emphasizes U.S. equities (approximately 93%) supplemented by non-U.S. stocks (around 6%), cash, and sector allocations led by technology (over 40%); it employs a quantitative investment process and maintains a low turnover rate of about 17%, with a net expense ratio of 0.86% and minimum initial investments of $2,500 for non-retirement accounts or $1,000 for IRAs. American Century Investments, the fund's sponsor, founded in 1958 and headquartered at 4500 Main Street in Kansas City, Missouri, operates as an independent global asset manager serving financial professionals, institutions, corporations, and individual investors through mutual funds, ETFs, collective investment trusts, separately managed accounts, and private investments; the firm maintains offices in New York, London, Hong Kong, Sydney, and other locations, managing over $300 billion in assets under supervision as of September 2025. Recent developments at American Century Investments include achieving a historic $300 billion milestone in assets under supervision in September 2025 driven by client-focused growth and innovation across investment vehicles; launching Small Cap Insights ETFs (ACSG and ACSV) in October 2025 to expand its active ETF platform with benchmark-consistent small-cap strategies; completing the integration of a private investments team from 3x5 Partners in September 2023 to enter early-stage growth investing in healthcare and climate sectors for institutional and high-net-worth clients; and closing the Emerging Markets Bond ETF (AEMB) in 2024 as part of lineup adjustments. The firm maintains a strategic alliance with Nomura Holdings, which holds a 41% economic interest since 2016, enabling complementary product distribution in Japan, Asia, and the U.S., while directing over 40% of profits annually to the Stowers Institute for Medical Research. ACFOX, launched on May 31, 2006, is managed by Keith Lee and Henry He since 2016, with John Rabroker joining in July 2024, and ranks in the Large Growth category with strong historical performance, including 28.90% one-year returns as of recent data.
