Factors Affecting Performance [Text Block] | How did the Fund perform last year? What affected the Fund’s performance? Entering 2024, investors focused on the pace at which inflation would normalize. Despite a slow start in reducing inflationary concerns, economic growth across major economies was more resilient and broad-based than expected. This led to increased optimism about the economic outlook and strong equity performance. Real Estate, a notable rate-sensitive asset class, tends to outperform in falling rate environments and underperform in rising rate environments. For the AB All Market Real Return Portfolio, our strategic allocation to Real Estate was a significant contributor, especially in the third quarter following the US Federal Reserve's first rate cut in September. Similarly, the Portfolio's exposure to inflation-sensitive equities contributed, driven by the broad-based equity market rally in 2024. However, our modest tactical underweights to Real Estate and commodity producers detracted from relative performance. The AB All Market Real Return Portfolio allocates to various inflation-sensitive asset classes, including real estate, commodity producers, commodity futures, FX, inflation-sensitive equities and future natural resource equities. From a security selection standpoint, the Portfolio benefited from positive selection within Real Estate but was hurt by negative selection within future natural resource equities. |
