At Invesco Fixed Income, we believe a portfolio’s tracking error is an inadequate measure of volatility when it comes to local currency emerging market debt because it gives equal treatment to the positive and negative differences between a portfolio and its benchmark.
Thus, to reduce volatility throughout the emerging market cycle, we employ asymmetric risk budgeting by generally taking tracking error below that of the benchmark’s long-term standard deviation. For example, if tracking error is 6% and the benchmark has a standard deviation of 12%, we typically stay in the 6-12% range for standard deviation not in the 12–18% range.
- Maintaining a low tracking error and high volatility in risk-on periods.
- Maintaining a high tracking error and low volatility in risk-off periods.
Locally denominated debt securities in emerging markets expose investors to a variety of risks driven by foreign exchange, credit quality, interest rates, macroeconomic conditions, and regional politics. This unique combination of risks, in our view, warrants special emphasis on limiting potential downside.
We believe this is best achieved through manager skill, which at the same time can wring value from market exposure to attractive yields and income.
