| Factors Affecting Performance [Text Block] | What affected the Fund's performance this period? • U.S. equities gained for the 12 months ending July 31, 2024, driven by resilient corporate profits, a frenzy over generative artificial intelligence and the Federal Reserve’s likely pivot to cutting interest rates later this year. • Against this backdrop, diversified banks (+35%) contributed most to the fund's performance for the fiscal year.

In that same industry, Block returned -23% and further weighed on the fund's performance. Among regional banks, New York Community Bancorp (-74%) hindered the fund’s return as well. Lastly, in the consumer finance industry, the fund’s exposure to Sofi Technologies (-34%) and Upstart Holdings (-59%) also were detrimental to performance. | |
