| Factors Affecting Performance [Text Block] | How did the Fund perform during the reporting period? For the 12 months ended October 31, 2024, the Fund underperformed its benchmark, the Russell 1000 Value Index. U.S. economic growth hovered around 3% on a year-over-year basis during the period, quelling recession fears. The Federal Reserve embarked on a rate-cutting cycle toward the end of the period, and the year-over-year rate of consumer price inflation eased to around 2.5%. U.S. stocks posted very strong returns. The Fund’s holdings in the health care and financial sectors detracted most from performance, while selection in information technology was the strongest contributor. All 11 industry sectors recorded positive returns, but only three finished higher than the benchmark. For the 10 years ended October 31, 2024, the Fund surpassed its benchmark by about 1 percentage point on an annualized basis. |
