About AIORX

The American Century International Opportunities Fund Class R is an open-end mutual fund that focuses on achieving long-term capital growth by investing primarily in equity securities of small-cap companies located outside the United States. The fund applies a fundamental, bottom-up stock selection approach, targeting aggressive growth stocks with significant potential in both developed and emerging markets. By benchmarking its performance against the MSCI ACWI ex-U.S. Small Cap Growth Index, the fund offers exposure to a diverse set of international small-cap growth opportunities, aiming to capitalize on the dynamic potential of smaller companies globally. The fund is tailored specifically for retirement plan investors, providing access to sectors and regions that may not be adequately represented in large-cap or U.S.-centric portfolios. Its strategy is designed to help diversify risk through geographic and sectoral variety, though it can be subject to volatility and unique risks associated with international, small-cap, and emerging market investments.
