Redden Capital Management manages an intermediate, high-quality bond portfolio with a value of $12 million dollars. The modified duration of the portfolio is 4.4 years with a yield beta of 1.0. Scott Stuart, the manager of the portfolio is concerned about rising interest rates over the next few months and wants to make a tactical adjustment and cut the duration of the portfolio in half. Stuart asks Amy Swemba, a junior portfolio manager with Redden, to accomplish this task. Swemba is aware that a Treasury bond futures contract exists with a value of $102,000, with a modified duration of 8.2 years. Swemba replies to Stuart’s comments with the following statements:Statement 1: | The fastest and most cost-effective way to reduce the duration of the portfolio by half would be to sell $6 million dollars worth of the actual bonds in the portfolio. | | Statement 2: | The portfolio’s duration could also be adjusted by selling 40 of the Treasury bond futures contracts. |
After listening to Swemba’s statements, Stuart should:
A)
| disagree with Statement 1, but agree with Statement 2. |
| B)
| agree with Statement 1, but disagree with Statement 2. |
| C)
| disagree with both Statement 1 and Statement 2. |

NOTE – on the exam, it is very likely for material on tactical asset allocation to be tested in conjunction with material from derivatives as tactical asset allocation can be accomplished by selling assets, or with a derivative overlay. Stuart should disagree with both of Swemba’s statements. Although Stuart’s goal of reducing the duration could be accomplished by selling bonds in the portfolio, doing so would likely incur significant transaction costs. Also, since the duration of each bond in the portfolio is likely different, specific bonds would have to be selected in order to accomplish Stuart’s goal, making the process more difficult. A derivative overlay, accomplished by using futures contracts, would be much easier and cost effective. Swemba is also incorrect with respect to the number of futures contracts that would need to be sold. The correct number of futures contracts to be sold is: (1.0)[(2.2 – 4.4) / 8.2]($12,000,000 / $102,000) = -31.56 ≈ -32 futures contracts. The minus sign means that 32 contracts should be sold to achieve the desired duration in the portfolio. |
