| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Class A shares of the Fund returned 17.33% (unadjusted for sales charges) for the period ended September 30, 2024. The Fund's broad-based index, the Russell 3000 ® ® ® The Fund’s underperformance was primarily driven by its relatively defensive positioning. In addition, the factors that the Fund is most correlated with, including earnings relative to assets, operating cash flow yield, and sales relative to enterprise value, performed unusually poorly during the period. Leading individual contributors to relative performance included Stride, Inc. (4.0%), a digital education company. Stride continues to benefit from steady enrollment growth in its K–12 programs. The company increasingly appears to be the beneficiary of a structural shift toward online forms of primary and secondary education. Sprouts Farmers Market, Inc. (2.3%) bucked the challenging macro backdrop for consumer-facing companies as a result of both the company’s specific initiatives and the resilience of its premium natural and organic product selection. RadNet, Inc. (2.0%) is a leading U.S. operator of freestanding diagnostic imaging centers. The stock performed well as RadNet is experiencing accelerating volume growth at its imaging centers as a result of both artificial intelligence initiatives and its long-term strategic positioning in the healthcare ecosystem relative to higher cost hospital-based providers. The most significant individual detractors from relative performance included Cross Country Healthcare, Inc. (0.6%), which saw its shares decline due to the soft market for healthcare staffing following belt tightening by hospitals. While the Fund trimmed exposure to the stock during the period, it maintained a position on a positive view of the company’s long-term outlook. Results for petroleum refiner PBF Energy, Inc. (0.7%) suffered due to weak pricing for gasoline and diesel. Holdings of the stock were trimmed during the period, but the Fund maintained a position on the view that the stock was undervalued relative to a conservative estimate of the net present value of PBF’s future cash flows. Titan Machinery, Inc. (0.7%) has been negatively impacted by a cyclical downturn in demand for farm equipment. The Fund added to the position on the view that the stock has substantial upside potential over the next three-to-five years as the demand cycle bottoms out and inflects positively. Percentages in parentheses are based on the Fund’s net assets as of September 30, 2024. |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Class R6 shares of the Fund returned 17.77% for the period ended September 30, 2024. The Fund's broad-based index, the Russell 3000 ® ® ® The Fund’s underperformance was primarily driven by its relatively defensive positioning. In addition, the factors that the Fund is most correlated with, including earnings relative to assets, operating cash flow yield, and sales relative to enterprise value, performed unusually poorly during the period. Leading individual contributors to relative performance included Stride, Inc. (4.0%), a digital education company. Stride continues to benefit from steady enrollment growth in its K–12 programs. The company increasingly appears to be the beneficiary of a structural shift toward online forms of primary and secondary education. Sprouts Farmers Market, Inc. (2.3%) bucked the challenging macro backdrop for consumer-facing companies as a result of both the company’s specific initiatives and the resilience of its premium natural and organic product selection. RadNet, Inc. (2.0%) is a leading U.S. operator of freestanding diagnostic imaging centers. The stock performed well as RadNet is experiencing accelerating volume growth at its imaging centers as a result of both artificial intelligence initiatives and its long-term strategic positioning in the healthcare ecosystem relative to higher cost hospital-based providers. The most significant individual detractors from relative performance included Cross Country Healthcare, Inc. (0.6%), which saw its shares decline due to the soft market for healthcare staffing following belt tightening by hospitals. While the Fund trimmed exposure to the stock during the period, it maintained a position on a positive view of the company’s long-term outlook. Results for petroleum refiner PBF Energy, Inc. (0.7%) suffered due to weak pricing for gasoline and diesel. Holdings of the stock were trimmed during the period, but the Fund maintained a position on the view that the stock was undervalued relative to a conservative estimate of the net present value of PBF’s future cash flows. Titan Machinery, Inc. (0.7%) has been negatively impacted by a cyclical downturn in demand for farm equipment. The Fund added to the position on the view that the stock has substantial upside potential over the next three-to-five years as the demand cycle bottoms out and inflects positively.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Class S shares of the Fund returned 17.61% for the period ended September 30, 2024. The Fund's broad-based index, the Russell 3000 ® ® ® The Fund’s underperformance was primarily driven by its relatively defensive positioning. In addition, the factors that the Fund is most correlated with, including earnings relative to assets, operating cash flow yield, and sales relative to enterprise value, performed unusually poorly during the period. Leading individual contributors to relative performance included Stride, Inc. (4.0%), a digital education company. Stride continues to benefit from steady enrollment growth in its K–12 programs. The company increasingly appears to be the beneficiary of a structural shift toward online forms of primary and secondary education. Sprouts Farmers Market, Inc. (2.3%) bucked the challenging macro backdrop for consumer-facing companies as a result of both the company’s specific initiatives and the resilience of its premium natural and organic product selection. RadNet, Inc. (2.0%) is a leading U.S. operator of freestanding diagnostic imaging centers. The stock performed well as RadNet is experiencing accelerating volume growth at its imaging centers as a result of both artificial intelligence initiatives and its long-term strategic positioning in the healthcare ecosystem relative to higher cost hospital-based providers. The most significant individual detractors from relative performance included Cross Country Healthcare, Inc. (0.6%), which saw its shares decline due to the soft market for healthcare staffing following belt tightening by hospitals. While the Fund trimmed exposure to the stock during the period, it maintained a position on a positive view of the company’s long-term outlook. Results for petroleum refiner PBF Energy, Inc. (0.7%) suffered due to weak pricing for gasoline and diesel. Holdings of the stock were trimmed during the period, but the Fund maintained a position on the view that the stock was undervalued relative to a conservative estimate of the net present value of PBF’s future cash flows. Titan Machinery, Inc. (0.7%) has been negatively impacted by a cyclical downturn in demand for farm equipment. The Fund added to the position on the view that the stock has substantial upside potential over the next three-to-five years as the demand cycle bottoms out and inflects positively.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Institutional Class shares of the Fund returned 17.69% for the period ended September 30, 2024. The Fund's broad-based index, the Russell 3000 ® ® ® The Fund’s underperformance was primarily driven by its relatively defensive positioning. In addition, the factors that the Fund is most correlated with, including earnings relative to assets, operating cash flow yield, and sales relative to enterprise value, performed unusually poorly during the period. Leading individual contributors to relative performance included Stride, Inc. (4.0%), a digital education company. Stride continues to benefit from steady enrollment growth in its K–12 programs. The company increasingly appears to be the beneficiary of a structural shift toward online forms of primary and secondary education. Sprouts Farmers Market, Inc. (2.3%) bucked the challenging macro backdrop for consumer-facing companies as a result of both the company’s specific initiatives and the resilience of its premium natural and organic product selection. RadNet, Inc. (2.0%) is a leading U.S. operator of freestanding diagnostic imaging centers. The stock performed well as RadNet is experiencing accelerating volume growth at its imaging centers as a result of both artificial intelligence initiatives and its long-term strategic positioning in the healthcare ecosystem relative to higher cost hospital-based providers. The most significant individual detractors from relative performance included Cross Country Healthcare, Inc. (0.6%), which saw its shares decline due to the soft market for healthcare staffing following belt tightening by hospitals. While the Fund trimmed exposure to the stock during the period, it maintained a position on a positive view of the company’s long-term outlook. Results for petroleum refiner PBF Energy, Inc. (0.7%) suffered due to weak pricing for gasoline and diesel. Holdings of the stock were trimmed during the period, but the Fund maintained a position on the view that the stock was undervalued relative to a conservative estimate of the net present value of PBF’s future cash flows. Titan Machinery, Inc. (0.7%) has been negatively impacted by a cyclical downturn in demand for farm equipment. The Fund added to the position on the view that the stock has substantial upside potential over the next three-to-five years as the demand cycle bottoms out and inflects positively. Percentages in parentheses are based on the Fund’s net assets as of September 30, 2024. |
