Factors Affecting Performance [Text Block]

How did the Fund perform last year?

  • For the reporting period ended July 31, 2025, the Fund returned 13.78%.

  • For the same period, the S&P Total Market Index returned 15.73%.

What contributed to performance?

While U.S. consumer spending remained resilient during the reporting period, consumer patterns began to shift towards prioritizing essentials. The consumer discretionary sector was the largest contributor to the Fund’s return. Notably, a major e-commerce firm in the broadline retail segment saw significant gains due to its expansion into groceries and continued growth of its cloud computing business. Among specialty retail names, automotive retail companies benefited. An online used car platform was supported by an increased demand for used cars, while an auto parts and accessories specialist gained as consumers held onto older vehicles for longer. In the consumer staples sector, a focus on value and affordability helped two large discount retailers, as well as customer loyalty, lower pricing, investments in technology, and e-commerce strength.

What detracted from performance?

There were no meaningful detractors from the Fund’s performance during the reporting period.
