Fund profile
As filed in the prospectus · 2025 Q4
The Funds investment objective is long-term growth of capital through a diversified and actively managed portfolio consisting of developing growth companies, many of which are traded over the counter.
The fund seeks long-term capital growth by actively selecting equity securities of small companies in their developing growth phase, defined as the period of rapid expansion after start-up when growth typically exceeds that of mature companies. The portfolio management team identifies companies it believes are strongly positioned within this phase, with at least 65% of net assets in small-cap equities as defined by the Russell 2000 Index range, and may allocate up to 20% to foreign securities including emerging markets. Because security selection depends on the portfolio team's assessment of individual companies' growth prospects and market positioning, fund performance will diverge from any index. The fund may engage in active and frequent trading and may use defensive strategies that could cause it to miss investment opportunities.
