| Factors Affecting Performance [Text Block] | Management’s discussion of Fund performance Performance highlights Delaware Ivy Wilshire Global Allocation Fund (Class A) returned 10.40% (excluding sales charge) for the 12 months ended June 30, 2024. Top contributors to performance: Slowing inflation and rallying global equity markets were the primary drivers of performance. Domestic large-cap growth and large-cap blend investment styles performed the strongest and contributed the most to Fund returns. Delaware Ivy Large Cap Growth Fund was the largest contributor to performance for the year. Top detractors from performance: Although inflation rates fell, concerns regarding the persistence of inflation kept global interest rates high. Although generally positive, global fixed income results were anemic when compared with global equities as rising interest rates served as a headwind to returns for funds that invest in most types of fixed income. The since-liquidated Delaware Ivy Total Return Bond Fund was the largest detractor from performance for the year. *The blended benchmark is computed using a combination of 65% MSCI ACWI Index (net) / 35% Bloomberg Multiverse Index (USD Hedged). |
