| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Class A shares of the Fund returned 15.11% (unadjusted for sales charges) for the period ended May 31, 2024. The Fund's broad-based index, the S&P 500 ® The Funds absolute performance was supported as healthcare stocks in aggregate finished the period higher. Within the Funds additional index, performance was led by pharmaceutical stocks, most notably large-capitalization companies bringing innovative treatments to market including GLP-1 drugs which have demonstrated efficacy in promoting weight loss. Leading contributors to the Funds outperformance vs. the additional index included pharmaceutical giant Eli Lilly and Company, which has seen strong sales of Mounjaro ® ® ® Leading detractors included Penumbra Inc., a global healthcare company focused on designing and manufacturing devices for clot removal and thrombectomy, aneurysm treatment and clots causing acute ischemic conditions. Shares declined as the company delayed the launch of a new product platform. UnitedHealth Group Inc. is a leading health insurance company offering commercial health insurance under Medicare Advantage and Medicaid plans. After a period of low health care utilization during COVID-19, United Health has experienced a period of elevated utilization resulting in higher-than-expected costs relative to total insurance premiums collected. Biogen Inc. develops, manufactures and commercializes therapies focused on neurology, oncology, and immunology. The company announced it was withdrawing its Alzheimers drug from the market and has also seen the loss of patent exclusivity and increased competition from generics for its multiple sclerosis treatment. | |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Institutional Class shares of the Fund returned 15.46% for the period ended May 31, 2024. The Fund's broad-based index, the S&P 500 ® The Funds absolute performance was supported as healthcare stocks in aggregate finished the period higher. Within the Funds additional index, performance was led by pharmaceutical stocks, most notably large-capitalization companies bringing innovative treatments to market including GLP-1 drugs which have demonstrated efficacy in promoting weight loss. Leading contributors to the Funds outperformance vs. the additional index included pharmaceutical giant Eli Lilly and Company, which has seen strong sales of Mounjaro ® ® ® Leading detractors included Penumbra Inc., a global healthcare company focused on designing and manufacturing devices for clot removal and thrombectomy, aneurysm treatment and clots causing acute ischemic conditions. Shares declined as the company delayed the launch of a new product platform. UnitedHealth Group Inc. is a leading health insurance company offering commercial health insurance under Medicare Advantage and Medicaid plans. After a period of low health care utilization during COVID-19, United Health has experienced a period of elevated utilization resulting in higher-than-expected costs relative to total insurance premiums collected. Biogen Inc. develops, manufactures and commercializes therapies focused on neurology, oncology, and immunology. The company announced it was withdrawing its Alzheimers drug from the market and has also seen the loss of patent exclusivity and increased competition from generics for its multiple sclerosis treatment. | |
