Assume that it is now 2016 and Marlene is currently evaluating two investment decisions: one involves an addition to their portfolio, the other a revision to it.

Dave and Marlene Carter live in the Boston area, where Dave has a successful orthodontics practice. Dave and Marlene have built up a sizable investment portfolio and have always had a major portion of their investments in fixed-income securities. They adhere to a fairly aggressive investment posture and actively go after both attractive current income and substantial capital gains. Assume that it is now 2016 and Marlene is currently evaluating two investment decisions: one involves an addition to their portfolio, the other a revision to it.

The Carters’ first investment decision involves a short-term trading opportunity. In particular, Marlene has a chance to buy a 7.5%, 25-year bond that is currently priced at $852 to yield 9%; she feels that in two years the promised yield of the issue should drop to 8%.

The second is a bond swap. The Carters hold some Beta Corporation 7%, 2029 bonds that are currently priced at $785. They want to improve both current income and yield to maturity and are considering one of three issues as a possible swap candidate: (a) Dental Floss, Inc., 7.5%, 2041, currently priced at $780; (b) Root Canal Products of America, 6.5%, 2029, selling at $885; and (c) Kansas City Dental Insurance, 8%, 2030, priced at $950. All of the swap candidates are of comparable quality and have comparable issue characteristics.

Case Problem 11.2     Grace Decides to Immunize Her Portfolio

Grace Hesketh is the owner of an extremely successful dress boutique in downtown Chicago. Although high fashion is Grace’s first love, she’s also interested in investments, particularly bonds and other fixed-income securities. She actively manages her own investments and over time has built up a substantial portfolio of securities. She’s well versed on the latest investment techniques and is not afraid to apply those procedures to her own investments.

Grace has been playing with the idea of trying to immunize a big chunk of her bond portfolio. She’d like to cash out this part of her portfolio in seven years and use the proceeds to buy a vacation home in her home state of Oregon. To do this, she intends to use the $200,000 she now has invested in the following four corporate bonds (she currently has $50,000 invested in each one).
