Fund profile

As filed in the prospectus · 2026 Q1

Capital appreciation.

Strategy · summarised

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.
