Factors Affecting Performance [Text Block] | What affected the Fund's performance this period? • U.S. taxable investment-grade bonds achieved a solid gain for the 12 months ending July 31, 2024. The period was marked by high levels of volatility, as investors anxiously awaited the arrival of interest-rate reductions by the U.S. Federal Reserve. • Against this backdrop, positioning in GNMA securities was the primary contributor to the fund's performance versus the benchmark, the Bloomberg GNMA Index, for the fiscal year. This relative gain was led by a timely overweight established last fall after GNMA securities suffered sharp selloffs in September and October. The bond class then rebounded through the end of 2023. • Picks among GNMAs, particularly overweights to securities with coupons 3% and below and 5% and above, also boosted the fund's relative performance. • The fund's non-benchmark exposure to 15- and 20-year Fannie Mae/Freddie Mac mortgage-backed securities provided another performance lift. • Overweights to MBS made up of reverse mortgages (including home equity conversion mortgages insured by the Federal Housing Administration) added value as well. • An overweight to government-agency securities made up of commercial mortgages was another notable contributor. These CMBS were among the mortgage market's best performers the past 12 months. • In contrast, the biggest detractor from relative performance was an untimely decision to reduce exposure to securities with coupons 5% and above in the fall of 2023. |
