| Factors Affecting Performance [Text Block] | Management's Discussion of Fund Performance The following discussion compares the performance of the Fund to the Russell Midcap Growth Index to show how the Fund’s performance compares to the returns of similar investments for the reporting period. See the Average Annual Total Returns table below for the returns of the Fund and related indexes, including the Russell 3000 Index, which represents approximately 98% of investable U.S. equities by market capitalization. The Fund seeks to provide capital appreciation by investing principally in common stocks of small and medium-sized companies that are traded on national securities exchanges, the NASDAQ stock market and on the over-the-counter market. Top Contributors to Performance ■ By sector, allocation to the Industrials and Financials sectors positively affected Fund relative performance. ■ Top individual Fund holdings that contributed positively to performance included Apollo Global, Blue Owl, Eaton Corp., Hamilton Lane, Quanta Services and Trane Technologies. ■ Fund holdings in the Consumer Staples sector also led to outperformance as companies with pricing power were able to pass price increases through to customers during the reporting period. Top Detractors from Performance ■ The allocation to the Healthcare sector detracted from Fund relative performance as these stocks lagged the overall market significantly during the reporting period. ■ By sector, stock selection in Real Estate detracted from Fund relative performance. ■ A top individual Fund holding that detracted from performance was New Fortress Energy, Inc. |

| Factors Affecting Performance [Text Block] | Management's Discussion of Fund Performance The following discussion compares the performance of the Fund to the Russell 1000 Growth Index to show how the Fund’s performance compares to the returns of similar investments for the reporting period. See the Average Annual Total Returns table below for the returns of the Fund and related indexes, including the Russell 3000 Index, which represents approximately 98% of investable U.S. equities by market capitalization. The Fund seeks to provide capital appreciation by investing primarily in securities of large-cap companies traded on national security exchanges, the NASDAQ stock market and on the over-the-counter market. Top Contributors to Performance ■ By sector, allocations to Consumer Staples, Industrials and Materials positively affected Fund relative performance. ■ The Materials sector contributed to performance of the Fund as inflation persisted which benefitted Fund holdings like Sherwin Williams and Ecolab which were able to pass along pricing with a profit margin boost. ■ Top individual Fund holdings that contributed positively to performance included BlackRock, Inc., Costco, Eaton Corp., Quanta Services and Trane Technologies. Top Detractors from Performance ■ Stock selection in the Healthcare and Communication Services sectors detracted the most from Fund relative performance. ■ The allocation to the Technology sector was a laggard for the Fund as the underweight to the sector and stock selection detracted from Fund relative performance. |

| Factors Affecting Performance [Text Block] | Management's Discussion of Fund Performance The following discussion compares the performance of the Fund to the Russell 1000 Growth Index to show how the Fund’s performance compares to the returns of similar investments for the reporting period. See the Average Annual Total Returns table below for the returns of the Fund and related indexes, including the Russell 3000 Index, which represents approximately 98% of investable U.S. equities by market capitalization. The Fund seeks to provide capital appreciation by investing primarily in securities of large-cap companies traded on national security exchanges, the NASDAQ stock market and on the over-the-counter market. Top Contributors to Performance ■ By sector, allocations to Consumer Staples, Industrials and Materials positively affected Fund relative performance. ■ The Materials sector contributed to performance of the Fund as inflation persisted which benefitted Fund holdings like Sherwin Williams and Ecolab which were able to pass along pricing with a profit margin boost. ■ Top individual Fund holdings that contributed positively to performance included BlackRock, Inc., Costco, Eaton Corp., Quanta Services and Trane Technologies. Top Detractors from Performance ■ Stock selection in the Healthcare and Communication Services sectors detracted the most from Fund relative performance. ■ The allocation to the Technology sector was a laggard for the Fund as the underweight to the sector and stock selection detracted from Fund relative performance. |

| Factors Affecting Performance [Text Block] | Management's Discussion of Fund Performance The following discussion compares the performance of the Fund to the Russell Midcap Growth Index to show how the Fund’s performance compares to the returns of similar investments for the reporting period. See the Average Annual Total Returns table below for the returns of the Fund and related indexes, including the Russell 3000 Index, which represents approximately 98% of investable U.S. equities by market capitalization. The Fund seeks to provide appreciation of capital by investing primarily in domestic, mid cap common stocks that offer superior growth prospects. Top Contributors to Performance ■ An overweight position in and solid stock selection among younger companies with strong analyst conviction contributed positively to Fund relative performance. ■ By sector, stock selection in Consumer Discretionary and Information Technology aided performance. ■ Top individual Fund holdings that contributed positively to performance included overweight positions in AppLovin Corp. (Class A), Allison Transmission Holdings, Inc. and Spotify Technology SA. Top Detractors from Performance ■ An underweight position in companies with negative analyst conviction, positive free cash flow and weakening earnings to price ratios detracted from Fund relative performance. ■ By sector, stock selection in Financials detracted from performance. ■ Top individual Fund holdings that detracted from performance were underweight positions in Palantir Technologies Inc. (Class A) and Fair Isaac Corporation. |
