| Factors Affecting Performance [Text Block] | How did the Fund perform in the period? For the period December 6, 2023 (inception) through October 31, 2024, the Fund slightly underperformed the Russell 1000 Growth Index (USD) (TR), delivering a cumulative inception to date return of 28.57% (NAV) compared to the benchmark's 30.34%, resulting in a performance variation of -1.77%. What factors influenced the fund’s performance? The Information Technology sector contributed positively to relative performance due to strong stock picking. A sizable overweight in Nvidia, the market leader in supplying key technologies for generative artificial intelligence, drove strong performance within the sector. The Fund also benefited from an underweight in the Consumer Staples sector which declined over the stated period, significantly underperforming the Russell 1000 Growth Index (USD) (TR). Positive relative returns in the Health Care sector came from Intuitive Surgical, sparked by a rebound in the company’s robotic surgery procedure growth. Meta Platform, another top contributor, successfully implemented Generative Artificial Intelligence driving increased advertising revenue growth. Detracting from the Fund’s relative returns was the Health Care sector due to an overweight in an underperforming sector as well as unfavorable stock selection. Specifically, Dexcom led the detractors as growing competition in the constant glucose monitoring market negatively impacted the company’s outlook. How is the fund positioned? The Fund’s investment strategy concentrates on companies with dominant market positions, manifested in high and durable free cash flow margins. Notably, Generative AI is impacting capital investment decisions throughout the economy, as diverse industries look to improve efficiencies with this nascent technology. | |
