- American Century Ultra Fund - I Class (TWUIX) is an open-end equity mutual fund managed by American Century Investments that seeks long-term capital growth through investments primarily in large-cap growth stocks of companies demonstrating accelerated earnings or revenue growth and high profitability. The fund employs a bottom-up fundamental analysis approach, focusing on quality-oriented securities across diversified sectors such as technology, healthcare, and consumer discretionary; it benchmarks performance against the Russell 1000 Growth Index and maintains a portfolio turnover of approximately 7%, with assets under management exceeding $26 billion as of mid-2025. Available exclusively through financial intermediaries with a minimum initial investment of $5 million, TWUIX features a net expense ratio of 0.67%-0.69% following management fee waivers in effect through July 31, 2026. American Century Ultra Fund - I Class operates within the large growth category, targeting institutional and high-net-worth investors seeking exposure to U.S. equities comprising about 98% U.S. stocks, 1% non-U.S. stocks, and minimal cash; the fund emphasizes stock selection over market timing to deliver style-pure large-cap growth returns. American Century Investments, the fund's adviser, founded in 1958 as Twentieth Century Mutual Funds and rebranded in 1997, is headquartered at 4500 Main Street in Kansas City, Missouri, with additional offices in New York, London, Hong Kong, and Sydney; the firm manages over $200 billion in assets and supports a portion of its dividends to the Stowers Institute for Medical Research. In recent developments, American Century Investments announced in July 2025 plans to close and liquidate two ETFs, Quality Preferred ETF (QPFF) and Quality Convertible Securities ETF (QCON), as part of portfolio optimization, while its ETF assets reached $72 billion by June 30, 2025; the firm also launched two new actively managed funds in 2025 to expand its offerings. Earlier strategic expansions include the 2023 completion of a transaction integrating the 3x5 Partners venture capital team to enter the $10 trillion private markets, focusing on impact investing in healthcare and climate solutions from Portland, Oregon. These moves align with ongoing fee waivers for Ultra Fund share classes and quarterly performance commentaries highlighting resilience amid market highs in Q2 2025.
