| Factors Affecting Performance [Text Block] | What drove fund performance during the past 12 months? Stocks in South Africa surged in the year ended October 31, 2024. Investors were greatly encouraged by the national elections in May 2024, which resulted in the African National Congress forming a Government of National Unity with the Democratic Alliance, a party viewed as economically liberal and market friendly. The oil price traded down as expectations for lower global oil demand growth, particularly from China, more than offset concerns over escalating regional geopolitical tensions. Saudi Arabian stocks registered gains; however, economic growth expectations for the kingdom were revised down. Versus the MSCI Arabian Markets & Africa 10/40 Investable Market Index Net, stock selection in the United Arab Emirates made a significant contribution to relative performance. Shares in Parkin soared following the Dubai-based parking operator’s initial public offering in February 2024. On a sector basis, energy contributed significantly to portfolio returns, driven by holdings in Adnoc Logistics & Services and Adnoc Drilling. On the negative side, stock selection in Saudi Arabia was a detractor from relative performance. In particular, the portfolio had no exposure to a number of large benchmark heavyweight names whose shares rose strongly over the review period. These included ACWA Power and Saudi Arabian Mining Co (Ma'aden), both excessively valued, in our view. On a sector basis, the lack of exposure to real estate names in the United Arab Emirates, where population growth has been stronger than we expected, weighed on relative returns. The fund seeks to deliver long-term growth of capital by identifying companies with attractive valuations and earnings that are growing faster than their local, regional, or global peers. We employ fundamental, bottom-up research supported by a top-down perspective that takes into account the relevant macroeconomic and political environment. | ||
