The funds investment objective is to seek capital appreciation.
The fund invests primarily in large-capitalization growth stocks selected through bottom-up fundamental analysis of individual companies, with a focus on those expected to deliver above-average earnings growth rates and duration. The fund may concentrate a significant portion of assets in a single issuer or small number of issuers, and may also invest meaningfully in foreign securities and single sectors. Because performance depends on the adviser's security selection, the fund's returns will diverge from the broader market based on which stocks are chosen.
