Key Takeaways
- The diversity and complexity of the bond market favors active managers over index tracking.
- The risk profile of a global flexible bond fund can change rapidly.
- The best funds in the category have an agile, wide-ranging investment process.
Given the inefficiencies, anomalies and variety in the bond market, there are large benefits to undertaking bottom-up research, both to uncover mispriced opportunities and to avoid defaults and downgrades. The challenges in price consistency and discovery, which make indexing difficult, are a blessing in disguise for active portfolio managers.
Flexible bond funds have the widest tool set of the fixed income coverage. Many are absolute-return oriented instead of being managed in relation to a traditional market index, and many present themselves as “all-weather” strategies that are expected to do well independently of the market cycle. Their flexibility is an enticing feature, as it allows the managers to express their views without constraints and to freely allocate to the bond market sectors that offer the best value over short, medium, and longer time frames.
At the same time, their wide leeway can make such funds more difficult to use in a broader portfolio: By definition, the risk profile of a global flexible bond fund can change rapidly. Therefore, while the category undoubtedly contains several gems, there are also many funds that have failed to use their flexibility for investors’ benefit.
How Should Investors Choose a Global Flexible Bond Fund?
Before investing in a global flexible bond fund, investors should consider the following key questions:
- Do the investment teams have relevant expertise in all of the different bond market subsectors they purport to scour for opportunities?
- Is there evidence of these teams getting tactical market calls consistently right?
- Have these teams experienced a full bond market cycle, including down markets, and how did they react when their strategy was out of favor?
- Global flexible bond funds tend to use derivatives-such as credit default swaps, futures contracts, and interest-rate swaps-more heavily than other, more traditional fixed income categories. Does the investment team have appropriate experience using derivatives, and are its risk management systems robust enough to monitor and stress-test these derivative exposures?
- What is a fair price to pay for potential alpha generation? The average fund in the EAA Global Flexible Bond category charges 1.06% in annual fees, or 1.28% for distribution share classes. That’s higher than its typical counterpart in the EAA Global Diversified Bond category, which charges 0.67%. and significantly more than a low-cost passive option tracking the global bond market.

This strategy’s seven-member global fixed-income committee averages 20 years’ experience, most spent at Dodge & Cox, with high personal investment in the strategy. While the firm has had some retirements in its senior ranks, leadership transitions have been orderly and Dodge & Cox invests heavily in talent development to prepare for the next generations of portfolio managers. In this strategy, the team builds a concentrated portfolio of 50-80 issuers, typically with a corporate bias and lower turnover than peers.
