Métricas de Risco

MBB, while providing access to mortgage-backed securities, carries certain risks. The fund's country exposure is heavily weighted towards 'Other' at 94.7%, which introduces geographical risk beyond the U.S. market. Although the fund invests in investment-grade mortgage-backed securities, the concentration in a single sector (Cash & Others at 100%) increases sector-specific risk. The fund's beta is 1.12, indicating that it is more volatile than the broader market. With over 11,141 holdings, the fund is well-diversified within its specific asset class, mitigating some concentration risk. The expense ratio of 0.0400% can be considered a low expense drag on returns. Past performance does not guarantee future results.
