| Factors Affecting Performance [Text Block] | WHAT AFFECTED THE FUND’S PERFORMANCE DURING THE REPORTING PERIOD? ■ During the reporting period, equities generally posted solid results driven by enthusiasm regarding generative artificial intelligence, the end to US Federal Reserve interest rate hikes, and continued growth in the US economy. Mid-cap stocks, as represented by the Russell Midcap Index, performed well in aggregate but trailed the large-cap S&P 500 Index. ■ Security selection within the consumer sectors, especially specialty retail and food products, added the most to the Fund’s performance relative to the Index. The Fund’s overweights in real estate and information technology and its underweight in healthcare also bolstered relative results. ■ Stock selection within healthcare (especially biotechnology), information technology (primarily due to software), and industrials (weighed down by professional services) were primary sources of weakness relative to the Index. |

| Factors Affecting Performance [Text Block] | WHAT AFFECTED THE FUND’S PERFORMANCE DURING THE REPORTING PERIOD? ■ During the reporting period, equities generally posted solid results driven by enthusiasm regarding generative artificial intelligence, the end to US Federal Reserve interest rate hikes, and continued growth in the US economy. Mid-cap stocks, as represented by the Russell Midcap Index, performed well in aggregate but trailed the large-cap S&P 500 Index. ■ Security selection within the consumer sectors, especially specialty retail and food products, added the most to the Fund’s performance relative to the Index. The Fund’s overweights in real estate and information technology and its underweight in healthcare also bolstered relative results. ■ Stock selection within healthcare (especially biotechnology), information technology (primarily due to software), and industrials (weighed down by professional services) were primary sources of weakness relative to the Index. |
