Factors Affecting Performance [Text Block]

WHAT FACTORS INFLUENCED PERFORMANCE FOR THE PERIOD?

The Fund provides a globally diversified portfolio with an allocation to stocks and bonds (through the Fund’s investment in broad-based ETFs) over a moderate time horizon. During the fiscal year ended July 31, 2024, the Fund outperformed shorter duration aggregate bond indices but underperformed longer duration stock indices due to the Fund’s defined duration strategy, which targets a ten-year duration. This is in line with our broader expectations of long-term returns, given that the fund will never be as aggressive as a pure equity portfolio or as conservative as a pure bond portfolio.

During the period, the Fund benefited from increased stability in the bond market as the Federal Reserve positions for interest rate cuts during lower inflation rates. The Fund outperformed Aggregate Bond Indices due to the Fund’s moderate exposure to global stocks. The Fund’s overweight bond allocation helped maintain relative stability, even as equities were highly volatile at times.
