Which statements regarding bond portfolio immunization are CORRECT?

• A. Immunization ensures that the value of a bond portfolio remains the same regardless of interest rate changes.
• B. Immunization is accomplished by creating a portfolio whose duration is equal to the investor's investment time horizon.
• C. Immunization allows investors to earn a current yield that is equal to the yield to maturity.
• D. Immunization provides a specific rate of return, regardless of interest rates.

Answer: (B)

The concept of bond portfolio immunization primarily revolves around managing interest rate risk to ensure that the portfolio will provide sufficient funds at a specific future date to meet a financial obligation. This is effectively achieved when a portfolio's duration matches the investor's investment time horizon. When the duration of a bond portfolio is equal to the investment horizon, the portfolio is structured in such a way that any changes in interest rates do not affect the investor's ability to meet that future cash flow requirement. This is due to the fact that as interest rates change, the price of bonds will fluctuate, but the duration matching ensures that the investor will have the necessary cash flow available at the end of their investment period, regardless of market fluctuations in bond prices. Other choices involve concepts related to bonds, but they do not precisely capture the essence of immunization. Such an understanding is essential for financial planners looking to mitigate interest rate risks across their clients' bond investments effectively.
