Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The A Class of the Fund returned 50.52% (with sales charges) and 59.74% (without sales charges) for the twelve months ended June 30, 2025, compared to the S&P 500 Index return of 15.16%.

• The headwinds that once pressured disruptive technologies lessened due to broader market participation, favorable policy shifts around crypto, Artificial Intelligence, and healthcare, coupled with expectations for potential fiscal catalysts like tax cuts.

• The Fund’s investments in software and capital markets companies materially helped performance for the period. Conversely, its investments in biotechnology and semiconductors and semiconductor equipment companies detracted from performance.
