- American Century Growth Fund Investor Class (TWCGX) is an open-end mutual fund managed by American Century Investments that seeks long-term capital growth by primarily investing in large-cap U.S. growth stocks of companies demonstrating improving business characteristics, such as accelerating earnings, revenue growth, and improving cash flows; the portfolio employs a risk-aware, systematic investment process using analytical research tools to identify securities of larger-sized companies meeting these criteria, with a focus on U.S. equities comprising approximately 98.6% of assets, supplemented by limited non-U.S. stocks (1.2%) and minimal cash (0.2%); top holdings include Microsoft Corp. (13.3%), NVIDIA Corp. (12.5%), Apple Inc. (9.0%), Alphabet Inc. (6.0%), and Broadcom Inc. (5.5%), representing 46.3% of the portfolio, with key sector allocations in technology (52.3%), communication services (13.7%), and consumer cyclical (13.1%). The fund offers Investor Class shares with a minimum initial investment of $2,500 for non-retirement accounts ($1,000 for IRAs), $50 for additional investments, and a net expense ratio of 0.84% following management fee waivers through at least July 31, 2026; it targets individual investors, financial advisors, institutions, and retirement plans through various share classes including A, C, I, R, R5, R6, and Y. Launched on June 30, 1971, the fund is domiciled in the United States with total net assets of approximately $16.23 billion and Investor Class assets of $11.43 billion; it is managed by a team including Justin Brown (since January 2016), Scott Marolf (since March 2020), and Joseph Reiland (since September 2021). American Century Investments, the fund's investment manager founded in 1958 and headquartered in Kansas City, Missouri, operates globally with offices in New York, London, Hong Kong, Sydney, Los Angeles, Santa Clara, and Portland, managing over $270 billion in assets under supervision across mutual funds, ETFs, institutional separate accounts, and retirement products. Recent developments include the completion of a transaction in September 2023 with the 3x5 Partners venture capital team to establish private investment capabilities focused on early-stage growth in healthcare and climate solutions, led by Nicholas Walrod, Tony Arnerich, and Joe Biller reporting to Chief Investment Officer Victor Zhang; in October 2025, American Century launched Small Cap Insights ETFs to expand its exchange-traded fund platform; the firm also made an investment in Claros Technologies via convertible note in August 2025, reflecting ongoing strategic expansion into private markets and innovative asset classes amid growing client demand.
