The worked question on this page is original educational practice. It is not represented as a question from an official previous-year examination paper.
01 / UNDERSTANDING
Review the question
Use an original practice case with identical bond terms but different purchase prices. Ask which amounts remain fixed and which yield measure changes. In paper analysis, underline whether the question asks for coupon income, current yield or a discounted-cash-flow yield, and check whether the quoted price includes or excludes accrued interest.
02 / UNDERSTANDING
The concept in context
Yield to maturity is a discount rate that equates the price with the promised cash flows under stated conventions. It is not a guarantee of the investor's realised return, which depends on factors such as sale price, payment performance and reinvestment. A precise discussion identifies the purchase price, holding period and cash-flow assumptions.
03 / UNDERSTANDING
A worked learning case
A fictional bond pays an annual coupon of 6 units on a face value of 100. One learner buys it for 100 and another for 90. Both receive the same promised coupon, but their current yields differ. The class then includes the eventual principal repayment to explain why current yield alone does not measure yield to maturity.
ORIGINAL EDUCATIONAL PRACTICE
Try it before you check.
Does buying a fixed-coupon bond at a lower price change its promised coupon amount?
Show the answer and reasoning
No; it changes the relationship between the purchase price and the cash flows.
The contractual coupon follows the bond's terms, not the price paid by a new holder in the market. A lower purchase price raises the coupon relative to that price, all else equal. A complete holding-period return still needs the remaining payments, any sale or redemption value and relevant reinvestment assumptions.
Two traps to watch for.
- Calling the coupon rate the investor's guaranteed realised return.
- Using current yield as if it included every remaining cash flow.
