| Factors Affecting Performance [Text Block] | How did the Fund perform in the last year? Market Summary: Fund Performance: Positioning: In Technology, the Fund trimmed its position in Monolithic Power after significant gains but maintains an overweight to semiconductors and semi-cap equipment. We believe this aligns with our focus on companies we view as poised to capitalize on the Gen-AI revolution. Healthcare was also a key sector, with an overweight in biotech, where clinical catalysts and promising product pipelines we believe offer opportunities. Additionally, we added to MedTech companies with strong financials, expecting that improved market sentiment has the potential to present attractive opportunities. Outlook: |
