This fund commits a substantial portion, at least 80% of its total assets, to investments in the underlying benchmark index's securities. This allocation also extends to American Depositary Receipts (ADRs) and Global Depositary Receipts (GDRs) that represent those same index components. The reference index itself is designed to reflect the overall performance of the broad Portuguese stock market, while still maintaining a minimum number of constituent companies. This investment vehicle is considered non-diversified.
