- American Century Ultra Investor Class (TWCUX) is an open-end mutual fund managed by American Century Investments that seeks long-term capital growth through investments primarily in common stocks of large-cap growth companies believed to exhibit accelerating earnings or revenue growth; the fund employs fundamental analysis of individual companies using quantitative research tools rather than broad economic forecasts, focusing on U.S. equities comprising approximately 98% of assets, with top holdings including NVIDIA Corp (16%), Apple Inc (9%), Microsoft Corp (7%), Amazon.com Inc (7%), and Alphabet Inc (5%), and leading sector allocations in technology (49%), communication services (16%), and consumer cyclical (14%). Investor Class shares feature a net expense ratio of 0.87%, a minimum initial investment of $2,500 for non-retirement accounts ($1,000 for IRAs), and no front-end or deferred loads, with daily pricing and availability through U.S. broker-dealers. The fund belongs to the large growth category, benchmarked against the Russell 1000 Growth Index, and as of December 17, 2025, reports a NAV of $91.39, YTD total return of 9.37%, and total net assets exceeding $28 billion across share classes.
Launched on November 2, 1981, and domiciled in the United States, the fund is headquartered with its investment manager, American Century Investments, at 450 W 7th Street in Kansas City, Missouri, serving retail and institutional investors focused on U.S. growth equity exposure. Portfolio management is led by Keith Lee (since 2008), Jeffrey Bourke (since 2013), and Tong Li (since July 2024), marking a recent addition to the team amid ongoing strategy execution. The Investor Class represents the largest share class at approximately $23.84 billion in assets.
Recent developments at American Century Investments include a management fee waiver extended through July 31, 2026, capping the Investor Class fee at 0.86% to enhance competitiveness; the addition of Tong Li to the Ultra Fund portfolio management team in July 2024; and broader firm milestones such as Avantis Investors (a global offering from American Century) surpassing $100 billion in assets under management in December 2025, fueled by nearly $27 billion in net new investments through November 2025. These changes reflect American Century's strategic emphasis on growth-oriented capabilities, sustained strategic alliances like the longstanding non-controlling partnership with Nomura Holdings (established 2016), and expansion into private markets via the 2023 integration of the 3x5 Partners venture capital team. The firm maintains operations primarily in the U.S., with international reach through partners in Europe, Australia, and Asia.
