FYI: Bonds issued by United States companies with strong balance sheets have been delivering the weakest returns of all major American bond categories this year, adding to the headaches of fixed-income investors.
There have been plenty of problems affecting all bonds. Rising interest rates pushed yields higher and bond prices lower.
So far, higher yields have not offset the declines in bond prices. (Total return in a bond fund is the combination of a portfolio’s yield and the changes to the price of its bonds.)
