The Most Boring Blog You’ll Read All Year: Bonds


For the first time in over a decade, investors are reconsidering the bond holdings in their portfolio. Rising interest rates over the past year have eroded bond values leading to the worst year on record for bond returns (Think SVB). This has impacted bonds with longer maturity the most as they are most sensitive to rate fluctuation. This has sparked conversations among investors and financial advisors to explore other opportunities for yield in their accounts outside of traditional bond funds.  

We began an extensive analysis of our fixed income holdings in January. This included several webinars and phone calls with fixed income experts, academics, and one of our bond managers1. These individuals operate and analyze the fixed income market daily.  The objective was simple: explore options for fixed income in our portfolios to ensure we’re maximizing investor value where possible. Further, to better understand how these experts view fixed income in this evolving environment. Our fundamental question was:

Do we replace bond funds in our portfolios with short-term treasuries?


There is more to consider than rates or current value when analyzing bond portfolios.  As rates increase and prices fall, the total rate of return that will be earned by a bond when it makes all interest payments and repays original principal also increases; known as the Yield to Maturity. While bond values have gone lower, holding them to maturity still means investors will be made whole as the face value of these bonds are repaid over time. Further, our bond managers actively search for new opportunities in the fixed income market every day, replacing underperforming bonds with more attractive holdings.  

In summary, our portfolios have always held short maturity and higher quality bonds to hedge against interest rate fluctuation. Using this disciplined method to fixed income which relies on market pricing and actively replacing underperforming bonds with more attractive holdings will continue to be a successful approach.
