| Factors Affecting Performance [Text Block] | How did the fund perform last six months and what affected its performance? The Fund's Institutional Class generated a total return of 14.44% during the six months ended June 30, 2024. This compares to the 15.29% return of the Fund’s benchmark, the S&P 500 Index, during the semiannual period. The Fund’s secondary benchmark, the Russell 1000 Growth Index, posted a return of 20.70% during the semiannual period. The Fund underperformed the S&P 500 ® ® Stock selection in the health care, consumer discretionary and communication services sectors detracted most from the Fund’s relative results. Within health care, having an overweighted allocation to the biotechnology industry, which performed weakly, and an underweighted exposure to the pharmaceuticals industry, which was the strongest segment of the sector, particularly dampened relative results. Having an overweighted allocation to consumer discretionary, which lagged the S&P 500 ® During the semiannual period, the stocks that detracted most from the Fund’s performance were molecular diagnostics company Exact Sciences, electric vehicle manufacturer Rivian Automotive and online dating services operator Match Group. Exact Sciences’ double-digit share price decline largely reflected competition risks, even as the company demonstrated strong execution and a sizable market opportunity for cancer tests, including its Cologuard for colon cancer. Shares of Rivian Automotive saw a double-digit price decline, partially due to economic and geopolitical uncertainties pressuring electric vehicle pricing as well as some competitive and financial concerns. Match Group’s shares fell substantially, largely driven by the lackluster performance of its Tinder segment, including lower than expected user growth. The individual stocks that contributed most positively to the Fund’s relative results were computer graphics processors manufacturer NVIDIA, cybersecurity technology company CrowdStrike Holdings and financial services platform operator Robinhood Markets. NVIDIA’s triple-digit share price advance, driven by strong quarterly results and execution and its leadership position in the fast-growing and transformational artificial intelligence (AI) semiconductor market. CrowdStrike Holdings enjoyed a significant double-digit share price gain, largely reflecting strong execution and demand for its AI software security solutions. Shares of Robinhood Markets saw a robust double-digit price gain, driven primarily by strong transaction revenue and deposit growth as well as increasing scale and profitability metrics. | |
