Frequently Asked Questions About TWUIX

What does TWUIX invest in?

The fund primarily invests in equity securities of companies that the advisor anticipates will increase in value over the long term. Portfolio managers make investment choices by conducting thorough analyses of individual companies, rather than basing decisions on general economic predictions. They utilize various analytical research tools and methods to pinpoint shares of substantial corporations that align with their investment prerequisites. In typical market environments, the managers focus on companies demonstrating not only growth in earnings or revenue, but an accelerating pace of expansion.

What is the expense ratio of TWUIX?

American Century Ultra Fund - I Class (TWUIX) charges an expense ratio of 0.67%. This is the annual fee deducted from fund assets to cover management and operations.

Is TWUIX a good long-term hold?

TWUIX is a leveraged fund designed to deliver a daily multiple of its underlying index. Daily reset compounding means returns over multi-day periods can diverge significantly from the headline multiple, typically with negative drift in choppy markets. These funds are designed for short-term tactical use, not buy-and-hold. Review the fund's prospectus before holding more than a few days.

How does TWUIX's daily reset work?

TWUIX rebalances exposure each trading day to maintain its target leverage ratio against the next day's move. The daily reset means returns compound at the daily level, so a +1%, −1% sequence on the underlying doesn't return the underlying to flat after the leverage multiplier. Over time this path-dependence erodes returns in volatile markets and amplifies them in trending markets.

How big is TWUIX?

American Century Ultra Fund - I Class (TWUIX) manages $25.78B in total assets. AUM determines bid-ask liquidity and the fund's vulnerability to closure. Funds below ~$50M are at higher risk of liquidation.

Is TWUIX actively managed or an index fund?

TWUIX's management style is described in the fund's prospectus. See the description on the Summary tab for the published strategy.
