Emerging Markets Debt Team

Bottom-Up and Top-Down Analysis

We believe a combination of bottom-up and top-down expertise deepens our understanding of performance drivers, improving the decision-making process.


We believe our robust, disciplined bottom-up and top-down research helps us better uncover mispricings in inefficient emerging markets debt. Our active approach is based on:

  • Rigorous fundamental research
  • Global macro analysis
  • Diversification discipline
  • Valuation focus
  • Integrated risk management
  • Integrated ESG analysis

The breadth of our team allows for specialization and regional focus, enhancing our ability to identify opportunities and to avoid unattractive risks.


The historical yield advantage of emerging markets debt over developed markets debt provides the potential for attractive risk-adjusted returns. We believe our disciplined bottom-up and top-down process helps us identify emerging markets debt with an attractive risk/reward profile, enabling us to deliver better outcomes for our portfolios and clients.
