Fund profile

This fund files no prospectus profile. Unit investment trusts and closed-end funds register on forms that carry no objective or fee tagging, and some fund families file without it — a gap in what was filed, not a fund without an objective or without fees.

Cumulative return· Jul 2023 – Apr 2026

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.
