Fund profile
As filed in the prospectus · 2026 Q1
Capital appreciation.
The fund invests in equity securities of companies the manager identifies as innovation leaders with superior management and competitive advantages across sectors, using fundamental bottom-up research to target sustainable earnings growth; it may concentrate holdings in fewer issuers than diversified funds and can hold up to 15% in foreign securities. Because the fund may at times hold a smaller number of issuers and higher percentages in individual companies due to market fluctuations, performance depends on the success of those concentrated positions.

These classes hold the same portfolio, so the 8.16pp spread over 5 years is the cost difference between them — roughly 1.63pp a year — not a difference in what they own.
May 2026 and Jun 2026 have been filed since the trailing figures were struck, so they are not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
