Take, for instance, the PIMCO Dynamic Income Fund ( PDI ), a complex taxable-bond-and-derivative fund that invests in similar assets as another CEF: the Western Asset Inflation-Linked Opportunities and Income Fund ( WIW ). WIWaEURtms 4.2% yield is half of PDIaEURtms 8.4%, but thataEURtms not the main reason IaEURtmll take the PIMCO fund over WIW. WIWaEURtms management has failed to deliver a strong return, even though their fundaEURtms mix of mortgage-backed securities, corporate bonds and derivatives is comparable to PDIaEURtms portfolio.
