| Factors Affecting Performance [Text Block] | What drove fund performance during the past 12 months? U.S. stocks advanced during the period, mainly driven higher by a narrow group of companies expected to benefit from artificial intelligence (AI) developments. Although inflation remained above the Federal Reserve’s long-term 2% target, the central bank shifted its focus toward the moderating labor market in the second half of the year and began reducing interest rates in mid-September. In the final months of the year, equity investors generally welcomed looser monetary policy and the U.S. election results. From an absolute perspective, the leading contributor to performance was the fund’s position in NVIDIA as shares benefited from a significant step-up in demand for advanced graphics processing units that are critical for the buildout of AI infrastructure. Apple also added value as investors appreciated the stabilization in its iPhone segment and the prospect of new AI features driving users to upgrade devices more frequently. Conversely, the leading detractor from absolute performance was Rivian Automotive due to the emerging electric vehicle manufacturer’s ongoing difficulty scaling production. Our stake in Dollar General also hurt returns. The stock fell when it became clear that an operational turnaround at the company was unlikely to materialize in the near term. The fund seeks to provide long-term capital growth through investments in the common stocks of well-established growth companies with leading market positions, seasoned management, and strong financial positions and with the potential for above-average growth and profitability. Information technology, consumer discretionary, and other traditional growth sectors remain areas of focus. |
