| Factors Affecting Performance [Text Block] | WHAT AFFECTED THE FUND’S PERFORMANCE DURING THE REPORTING PERIOD? ■ Global risk assets rallied over the reporting period even as concerns about a recession and rising yields led to some market volatility. US economic growth was resilient and inflationary pressures continued to ease, prompting the US Federal Reserve to start its rate-cutting cycle in September 2024, with a larger-than-expected reduction of 0.50%. Commodities struggled over the period, due to slowing manufacturing growth and softer oil demand, even as OPEC supply cuts approached their predetermined expiry date. Other real asset markets, such as global infrastructure, master limited partnerships (MLPs), real estate, and gold posted strong performance. ■ The Fund’s performance relative to the Custom Blended Index, a model portfolio consisting of the Bloomberg Commodity Index (33.3%), MSCI World Real Estate Net Index (33.3%), and Bloomberg US Treasury Inflation-Protected Securities (TIPS) Index (33.3%), benefited from an underweight in lagging treasury inflation-protected securities and commodities. Relative returns were also bolstered by out-of-Index exposure to outperforming MLPs, global infrastructure, and gold. ■ Underweight exposure to real estate, the best-performing asset class in the Index, detracted most from the Fund’s relative performance during the period. Among the Fund’s underlying funds, PGIM Jennison Global Infrastructure Fund, PGIM TIPS Fund, and PGIM Quant Solutions Commodity Strategies Fund all lagged their respective benchmarks, undermining relative returns. |
